Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a communication access method and apparatus. Background Technology

[0002] With rapid economic development, large banks have an increasing need for business collaboration with various partners. However, there are many partners, making it impossible to connect with banks through a unified communication protocol. Even if they all use the HTTP protocol, there will be different protocol versions, such as HTTP 1.0, HTTP 1.1, and HTTP 2.0. As the server, the bank needs to support various communication protocol versions.

[0003] Because the client protocol versions of partners vary significantly, and their business behaviors have many unique characteristics, protocol version incompatibility issues can easily arise when the bank's server-side undergoes protocol version changes. For example, previously all partners accessed the bank via the HTTP 1.1 protocol. One day, a partner requested access via the HTTP 2.0 protocol. The bank cooperated by modifying its system to support this communication access. However, this partner's transaction volume was very low, perhaps even zero for several months. During this period, the bank's server-side protocol version was upgraded rapidly, possibly with new versions released every month. The bank's server-side developers might easily overlook HTTP 2.0 support. As a result, after several protocol version updates, the server no longer supports HTTP 2.0. Then, one day, when a partner suddenly experiences a surge in transaction requests, the bank's server will experience numerous anomalies (generally, the server only has one port, which can easily cause a global impact), thereby affecting the access of other partners.

[0004] For this type of problem, since the server has updated multiple protocol versions, directly reverting to a previous server protocol version cannot guarantee that it will be applicable to all partners' clients, nor can it guarantee that the reverted protocol version will be suitable for the clients of partners with abnormal communication access. Therefore, it cannot be solved by reverting to the server protocol version. Generally, the only way to avoid this is to use a firewall to isolate the access of the partner, which will cause the partner's transaction to fail. Summary of the Invention

[0005] To address at least one problem in the prior art, this application proposes a communication access method and apparatus that can improve the reliability of communication access, thereby ensuring the stability of the financial transaction process.

[0006] To address the aforementioned technical problems, this application provides the following technical solution:

[0007] Firstly, this application provides a communication access method including:

[0008] When there is a client under test with abnormal communication access among the multiple clients corresponding to the financial institution's server, obtain the latest server protocol version and the server protocol version of the client under test during its last normal communication access.

[0009] Based on the latest server protocol version and the server protocol version during the last normal communication access, determine whether the client to be tested has a cross-version compatibility issue. If so, apply the server protocol version during the last normal communication access to complete the communication access of the client to be tested to the financial institution's server.

[0010] In one embodiment, the communication access method further includes:

[0011] By applying the latest server protocol version, the client other than the client to be tested can communicate with the financial institution's server.

[0012] In one embodiment, obtaining the latest server protocol version and the server protocol version of the client under test during its last normal communication access includes:

[0013] Obtain the latest server protocol version and the unique identifier of the client to be detected;

[0014] Based on the unique identifier of the client to be detected and the pre-stored access request processing information, the communication access time of the client to be detected during its last normal communication access is determined. The pre-stored access request processing information includes the correspondence between the unique identifier of the client to be detected and the communication access time of each normal communication access.

[0015] Based on the communication access time of the last normal communication access, obtain the version installation information from the pre-stored version installation information set, which has an effective time before the communication access time and an expiration time after the communication access time. Based on the version package storage path in the version installation information, obtain the server protocol version of the client under test during the last normal communication access.

[0016] In one embodiment, determining whether the client under test has a cross-version compatibility issue based on the latest server protocol version and the server protocol version during the last normal communication access, and if so, applying the server protocol version during the last normal communication access to complete the communication access of the client under test to the financial institution server, includes:

[0017] Determine whether the latest server protocol version differs from the server protocol version used during the last normal communication access by more than a preset number of protocol versions. If so, it is determined that the client under test has a cross-version compatibility issue, and the server protocol version used during the last normal access is applied to complete the communication access of the client under test to the financial institution's server.

[0018] In one embodiment, it also includes:

[0019] When there are no clients under test with abnormal communication access, the latest server protocol version is used to complete the communication access of each client to the financial institution's server.

[0020] In one embodiment, before obtaining the latest server protocol version and the server protocol version of the client under test during its last normal communication access, the method further includes:

[0021] After each server protocol version installation is completed, the version installation information of the server protocol version is added to the version installation information set. This version installation information includes: the version package save path, the effective time and the expiration time.

[0022] In one embodiment, after completing the client communication access to the financial institution server other than the client to be detected, the method further includes:

[0023] Store access request processing information for clients other than the client to be detected.

[0024] Secondly, this application provides a communication access device, comprising:

[0025] The acquisition module is used to acquire the latest server protocol version and the server protocol version of the client under test when there is an abnormal communication access among the multiple clients corresponding to the financial institution server.

[0026] The communication access module is used to determine whether the client to be tested has a cross-version compatibility issue based on the latest server protocol version and the server protocol version during the last normal communication access. If so, the client to be tested is used to complete the communication access to the financial institution's server by applying the server protocol version during the last normal communication access.

[0027] In one embodiment, the communication access device further includes:

[0028] The application module is used to apply the latest server protocol version to enable client communication access to the financial institution's server for clients other than the client to be tested.

[0029] In one embodiment, the acquisition module includes:

[0030] The acquisition unit is used to acquire the latest server protocol version and the unique identifier of the client to be detected;

[0031] The determining unit is configured to determine the communication access time of the client under test during its last normal communication access based on the unique identifier of the client under test and the pre-stored access request processing information. The pre-stored access request processing information includes the correspondence between the unique identifier of the client under test and the communication access time during each normal communication access.

[0032] The version installation information determination unit is used to obtain version installation information from a pre-stored version installation information set based on the communication access time during the last normal communication access. The version installation information includes versions whose effective time is before the communication access time and whose expiration time is after the communication access time. The version installation information is used to obtain the server protocol version of the client under test during the last normal communication access based on the version package storage path.

[0033] In one embodiment, the communication access module includes:

[0034] The judgment unit is used to determine whether the latest server protocol version differs from the server protocol version during the last normal communication access by more than a preset number of protocol versions. If so, it is determined that the client under test has a cross-version compatibility problem, and the server protocol version during the last normal access is applied to complete the communication access of the client under test to the financial institution server.

[0035] In one embodiment, the communication access device further includes:

[0036] The access module is used to enable each client to communicate and access the financial institution's server when there are no clients with abnormal communication access.

[0037] In one embodiment, the communication access device further includes:

[0038] The server-side version management module is used to add the version installation information of the server-side protocol version to the version installation information set after each server-side protocol version installation is completed. The version installation information includes: the version package storage path, the effective time and the expiration time.

[0039] In one embodiment, the communication access device further includes:

[0040] The client access record module is used to store access request processing information of clients other than the client to be detected.

[0041] As can be seen from the above technical solutions, this application provides a communication access method and apparatus. The method includes: when there is a client under test with abnormal communication access among multiple clients corresponding to the financial institution's server, obtaining the latest server protocol version and the server protocol version of the client under test during its last normal communication access; determining whether the client under test has cross-version compatibility issues based on the latest server protocol version and the server protocol version of the last normal communication access; if so, applying the server protocol version of the last normal communication access to complete the communication access of the client under test to the financial institution's server, which can improve the reliability of communication access and thus ensure the stability of the financial transaction process; it can achieve cross-version compatibility between clients and servers, cope with various special transaction behaviors of partners, and improve the high availability of the bank's server; specifically, by creating an independent specific server instance, clients with version compatibility issues can be restored to normal, without affecting existing clients and servers with normal access, with minimal intervention to the existing production environment, achieving multi-version compatibility of server communication access; through real-time access record management, it can proactively and automatically discover problems, and the environment can quickly self-recover without manual intervention, improving the efficiency of resolving server communication failures.

[0048] Figure 6 This is a schematic block diagram illustrating the system configuration of an electronic device according to an embodiment of this application. Detailed Implementation

[0049] To enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0050] In existing technologies, it is impossible to solve the problem of clients under test with abnormal communication access by directly rolling back the server protocol version; it is also difficult to analyze and locate the cause of the problem. There are many partners, and when the server suddenly becomes abnormal, it is difficult to determine which partner caused the problem, especially when the partner is not a new partner (it has been connected normally before).

[0051] To address at least one of the problems existing in the prior art and better ensure production safety and stability, as well as to deal with the incompatibility between client and server versions caused by various special transaction behaviors of partners, this application provides a communication access method and apparatus. By recording the relationship between client access and server version, when a client-server version incompatibility problem is detected, the method retrieves the server version that the client previously connected to normally, redeploys the specific version of the server, and routes the client's request to the specific server at the system level. This achieves multi-version compatibility for communication access and ensures that various clients with significant differences can access the server normally.

[0052] Therefore, in order to improve the reliability of communication access and thus ensure the stability of financial transactions, this application provides a communication access device. This device can be a server or a client device. The client device can include smartphones, tablet computers, network set-top boxes, portable computers, desktop computers, personal digital assistants (PDAs), in-vehicle devices, and smart wearable devices, etc. The smart wearable devices can include smart glasses, smartwatches, and smart bracelets, etc.

[0053] In practical applications, the communication access portion can be executed on the server side as described above, or all operations can be completed on the client device. The choice can be made based on the processing power of the client device and the limitations of the user's usage scenario. This application does not impose any limitations on this. If all operations are completed on the client device, the client device may further include a processor.

[0054] The aforementioned client device may have a communication module (i.e., a communication unit) that can communicate with a remote server to achieve data transmission. The server may include a server on the task scheduling center side; in other implementation scenarios, it may also include a server on an intermediate platform, such as a server on a third-party server platform that has a communication link with the task scheduling center server. The server may include a single computer device, a server cluster consisting of multiple servers, or a distributed server structure.

[0055] The server and the client device can communicate using any suitable network protocol, including network protocols not yet developed as of the date of this application. Such network protocols may include, for example, TCP / IP, UDP / IP, HTTP, HTTPS, etc. Of course, the network protocols may also include, for example, RPC (Remote Procedure Call Protocol) and REST (Representational State Transfer) protocols used on top of the above protocols.

[0056] It should be noted that the communication access method and apparatus disclosed in this application can be used in the field of financial technology, or in any field other than financial technology. The application field of the communication access method and apparatus disclosed in this application is not limited.

[0057] The following examples illustrate this in detail.

[0058] To improve the reliability of communication access and thus ensure the stability of financial transactions, this embodiment provides a communication access method in which the execution subject is a communication access device, including but not limited to a server, such as... Figure 1 As shown, this method specifically includes the following:

[0059] Step 100: When there is a client under test with abnormal communication access among the multiple clients corresponding to the financial institution server, obtain the latest server protocol version and the server protocol version of the client under test during its last normal communication access.

[0060] Specifically, the financial institution server can represent a bank server; the client can represent a client of the bank's partner, such as a mobile phone or tablet. An abnormal communication access by the client, i.e., an abnormal client access status, indicates that data communication between the client and the server is impossible. When an abnormal communication access error code is received from at least one of multiple clients corresponding to the financial institution server, the client sending the abnormal communication access error code is identified as the client to be tested for abnormal communication access. The abnormal communication access error code can be error code "400". The server protocol can be the HTTP protocol, and the protocol version can be HTTP 1.0, HTTP 1.1, HTTP 2.0, etc.

[0061] Step 200: Based on the latest server protocol version and the server protocol version during the last normal communication access, determine whether the client to be tested has a cross-version compatibility issue. If so, apply the server protocol version during the last normal communication access to complete the communication access of the client to be tested to the financial institution's server.

[0062] Specifically, the "last normal communication access" can refer to the most recent normal communication access. The system command IPTABLES can be used at the TCP / IP system level to transfer the communication access request of the client to be detected from the port of the latest server protocol version instance to the port of the server protocol version instance from the time of the last normal communication access. This allows the port of the server protocol version instance from the time of the last normal communication access to handle the access, thereby achieving compatible handling of multiple server version communication accesses.

[0063] To prevent abnormal client access from affecting other clients' communication access, and to ensure normal communication access for all clients, compatibility with multiple protocol versions is required. Figure 2 As shown, in one embodiment, the communication access method further includes:

[0064] Step 300: Apply the latest server protocol version to complete the client communication access to the financial institution server for clients other than the client to be tested.

[0065] To further improve the reliability of obtaining the server protocol version during the last successful communication access of the client under test, such as... Figure 3 As shown, in one embodiment, step 100 includes:

[0066] Step 101: Obtain the latest server protocol version and the unique identifier of the client to be tested.

[0067] Specifically, the unique identifier of the client to be detected is used to distinguish different clients, and it can be the client's IP address.

[0068] Step 102: Based on the unique identifier of the client to be detected and the pre-stored access request processing information, determine the communication access time of the client to be detected during its last normal communication access. The pre-stored access request processing information includes the correspondence between the unique identifier of the client to be detected and the communication access time during each normal communication access.

[0069] Specifically, the pre-stored access request information can be pre-stored locally on the communication access device.

[0070] Step 103: Based on the communication access time of the last normal communication access, obtain the version installation information from the pre-stored version installation information set, which has an effective time before the communication access time and an expiration time after the communication access time. Based on the version package storage path in the version installation information, obtain the server protocol version of the client to be tested during the last normal communication access.

[0071] To further improve the reliability of determining cross-version compatibility issues with clients, in one embodiment, step 200 includes:

[0072] Step 201: Determine whether the latest server protocol version differs from the server protocol version during the last normal communication access by more than a preset number of protocol versions. If so, it is determined that the client under test has a cross-version compatibility issue. Apply the server protocol version during the last normal access to complete the communication access of the client under test to the financial institution's server.

[0073] Specifically, the preset number can be set according to actual conditions, and this application does not impose any restrictions on it. For example, there is a difference of four protocol versions between the first version of the server protocol and the fifth version after version upgrade.

[0074] To further improve the reliability of communication access, in one embodiment, the communication access method further includes: when there are no clients under test with abnormal communication access, applying the latest server protocol version to complete the communication access of each client to the financial institution server.

[0075] Specifically, it can also store access request processing information for each client.

[0076] To further improve the reliability of the version installation information set, in one embodiment, before obtaining the latest server protocol version and the server protocol version of the client under test during its last normal communication access in step 100, the method further includes: after each server protocol version installation is completed, adding the version installation information of the server protocol version to the version installation information set, which includes: the version package storage path, the effective time, and the expiration time.

[0077] To further improve the reliability of access request processing information storage, in one embodiment, after the client other than the client to be detected has completed communication access to the financial institution's server, the method further includes: storing access request processing information of the client other than the client to be detected.

[0078] To address the problems existing in the prior art, this application provides an application example of a communication access method. Version deployment management is performed on the server side, saving each server version for subsequent redeployment. The processing status of each client access request is recorded, along with the latest time of each client's successful access and the server version number at that time. When a client access error occurs and the server version at the time of the client's last successful access differs from the latest version by more than two versions, it can be determined that there is a cross-version compatibility issue between the client and the server. This can trigger a specific version redeployment, and the client's access request can be specifically routed to a server with a specific version, thereby achieving multi-version compatibility for communication access. The specific description is as follows:

[0079] Step 1: During each server-side version installation, record the version installation information for each server-side version deployment. The version installation information includes: port, version number, effective time and expiration time, and version package storage path.

[0080] Step 2: Each time a client requests access, record the processing status of the client access request, i.e., access request processing information. Access request processing information includes: client IP, client version number, client HTTP communication protocol version, the time when the client last successfully accessed, access return status, etc.

[0081] Step 3: Based on the access time, obtain the server version number and server port information at that time. The client IP, client version number, and access return code are the unique keys for this information. Each time the client successfully accesses the network, the client access record module will obtain the client IP and client version number, and add the access return status to retrieve the access information. If it is not found, a new record will be added.

[0082] Step 4: If the client connection is determined to be abnormal, trigger multi-version compatibility processing and add a new record. This can be done by receiving an error code "400" from the client.

[0083] Step 5: Analyze the client and server version information from the client's last successful connection to determine if there are any version compatibility issues. If so, it can be determined that there is a cross-version compatibility issue between the client and server, and a redeployment of the specific version can be triggered.

[0084] Step 6: Based on the server version number of the last successful connection by the client, obtain the specific server version and start an instance of the specific server version on the server.

[0085] Step 7: Based on the IP address and HTTP protocol version of the specific client, at the TCP / IP system level, transfer the communication access request of the specific client from the port of the latest server version instance to the port of the specific server version instance, so that the specific server can handle the access.

[0086] From a software perspective, in order to improve the reliability of communication access and thus ensure the stability of financial transactions, this application provides an embodiment of a communication access device for implementing all or part of the communication access method, see [link to embodiment]. Figure 4 The communication access device specifically includes the following components:

[0087] The acquisition module 01 is used to acquire the latest server protocol version and the server protocol version of the client under test when there is an abnormal communication access among the multiple clients corresponding to the financial institution server.

[0088] The communication access module 02 is used to determine whether the client to be tested has a cross-version compatibility problem based on the latest server protocol version and the server protocol version during the last normal communication access. If so, the client to be tested is used to complete the communication access to the financial institution server by applying the server protocol version during the last normal communication access.

[0089] In one embodiment, the communication access device further includes:

[0090] The application module is used to apply the latest server protocol version to enable client communication access to the financial institution's server for clients other than the client to be tested.

[0091] In one embodiment, the acquisition module includes:

[0092] The acquisition unit is used to acquire the latest server protocol version and the unique identifier of the client to be detected;

[0093] The determining unit is configured to determine the communication access time of the client under test during its last normal communication access based on the unique identifier of the client under test and the pre-stored access request processing information. The pre-stored access request processing information includes the correspondence between the unique identifier of the client under test and the communication access time during each normal communication access.

[0094] The version installation information determination unit is used to obtain version installation information from a pre-stored version installation information set based on the communication access time during the last normal communication access. The version installation information includes versions whose effective time is before the communication access time and whose expiration time is after the communication access time. The version installation information is used to obtain the server protocol version of the client under test during the last normal communication access based on the version package storage path.

[0095] In one embodiment, the communication access module includes:

[0096] The judgment unit is used to determine whether the latest server protocol version differs from the server protocol version during the last normal communication access by more than a preset number of protocol versions. If so, it is determined that the client under test has a cross-version compatibility problem, and the server protocol version during the last normal access is applied to complete the communication access of the client under test to the financial institution server.

[0097] In one embodiment, the communication access device further includes:

[0098] The access module is used to enable each client to communicate and access the financial institution's server when there are no clients with abnormal communication access.

[0099] In one embodiment, the communication access device further includes:

[0100] The server-side version management module is used to add the version installation information of the server-side protocol version to the version installation information set after each server-side protocol version installation is completed. The version installation information includes: the version package storage path, the effective time and the expiration time.

[0101] In one embodiment, the communication access device further includes:

[0102] The client access record module is used to store access request processing information of clients other than the client to be detected.

[0103] The embodiments of the communication access device provided in this specification can be used to execute the processing flow of the embodiments of the above-described communication access method. Its functions will not be repeated here, but can be referred to the detailed description of the embodiments of the above-described communication access method.

[0104] To further illustrate this solution, and in conjunction with the application example of the aforementioned communication access method, this application provides an application example of a communication access device. In this application example, version deployment management can be performed on the server side, saving each server version for subsequent redeployment; the processing status of each client access request is recorded, along with the latest time of each client's successful access and the server version number at that time. When a client access error occurs and the server version at the time of the client's last successful access differs from the latest version by more than two versions, it can be determined that there is a cross-version compatibility issue between the client and the server. This can trigger a specific version redeployment, and the client's access request can be specifically routed to a specific version of the server, thereby achieving multi-version compatibility for communication access. The device specifically includes:

[0105] (I) Server-side version management module

[0106] This function is responsible for managing and storing server-side versions. Each time a server-side version is installed, it records the installation information for that version, including: port, version number, effective date, expiration date, and the path where the version package is saved. The saved version package can be used to redeploy a specific version of the server instance to restore access for certain clients.

[0107] (II) Client Access Record Module

[0108] This module is responsible for recording the processing status of client access requests, i.e., access request processing information. This information includes: client IP address, client version number, client HTTP protocol version, the last successful access time, and access return status. It also retrieves the server version number and server port information based on the access time. The client IP address, client version number, and access return code are unique keys for this information. Each time a client successfully accesses the server, the client access recording module retrieves the client IP address and client version number, along with the access return status, to search for access information. If no information is found, a new record is created; otherwise, the last successful access time is updated to the current time. If the client access is abnormal, the multi-version compatibility analysis module is triggered to perform multi-version compatibility processing and a new record is created. The functionality of the client access recording module is equivalent to the above.

[0109] (III) Multi-version compatibility analysis module

[0110] This module is responsible for analyzing the client and server version information from the client's last successful connection to determine if there are any version compatibility issues. The multi-version compatibility analysis module first checks if the client's current version is the same as the version used during the last successful connection. If so, it means the client hasn't been modified. Then, it checks if the server's current version differs from the version used during the last successful connection by more than two versions. If so, it can be determined that there is a cross-version compatibility issue between the client and server, triggering a redeployment of a specific version.

[0111] (iv) Specific version redeployment module

[0112] Based on the server version number from the client's last successful connection, a specific server version is retrieved from the server version package storage path. This server version has previously successfully connected to clients experiencing multi-version compatibility issues. Next, the server port for this specific server version is modified to differentiate it from the latest server version instance (which still provides external service). Then, a specific server version instance is started on the server, and finally, a specific access route is triggered.

[0113] (v) Specific access routing module

[0114] Based on the IP address and HTTP protocol version of a specific client, the system command IPTABLES redirects the client's communication access request from the port of the latest server version instance to the port of the specific server version instance at the TCP / IP system level, allowing the specific server to handle the access. This achieves compatibility handling for multi-version server communication access. The combined functionality of the multi-version compatibility analysis module, the specific version redeployment module, and the specific access routing module is equivalent to the functionality achieved by the aforementioned communication access module.

[0115] In one example, the connection between the client and the server is as follows: Figure 5 As shown, special clients, i.e., the characteristic versions of the client application server to be detected, communicate and access each other, while ordinary clients, i.e., the latest versions of the client application server other than the client to be detected, communicate and access each other. The server can be equivalent to the aforementioned communication access device.

[0116] From a hardware perspective, in order to improve the reliability of communication access and thus ensure the stability of financial transactions, this application provides an embodiment of an electronic device for implementing all or part of the communication access method. The electronic device specifically includes the following components:

[0117] The device comprises a processor, memory, a communications interface, and a bus; wherein the processor, memory, and communications interface communicate with each other via the bus; the communications interface is used to realize information transmission between the communications access device and related devices such as user terminals; the electronic device may be a desktop computer, tablet computer, or mobile terminal, etc., and this embodiment is not limited to these. In this embodiment, the electronic device can be implemented with reference to the embodiments for implementing the communications access method and the embodiments for implementing the communications access device, the contents of which are incorporated herein by reference, and repeated details will not be described again.

[0118] Figure 6 This is a schematic block diagram illustrating the system configuration of the electronic device 9600 according to an embodiment of this application. Figure 6 As shown, the electronic device 9600 may include a central processing unit 9100 and a memory 9140; the memory 9140 is coupled to the central processing unit 9100. It is worth noting that... Figure 6 This is an example; other types of structures can also be used to supplement or replace this structure to achieve telecommunications functions or other functions.
