Abstract

The present application discloses a method, device and system for storing function modules based on a microservice gateway, wherein when the gateway re-imports a legitimate function module, the function module will be stored in a network-attached storage server and a file server in the cluster respectively. When the gateway in any cluster is started or reloaded, it will be determined whether the function module is missing in the local disk. If so, the missing function module is first synchronized to the local disk through the network-attached storage server in the cluster. If the synchronization fails, the missing function module is synchronized from the file server to the local disk, and the function module is loaded from the local disk to provide corresponding functions externally, thereby avoiding gateway service anomalies caused by the loss of function modules and gateway service anomalies caused by inconsistent function modules of different gateways in the same cluster or different clusters, so that the gateway service can operate normally and the high availability of the gateway service is guaranteed.

Description

Technical Field

[0001] The present application relates to the field of Internet technology, and more specifically, to a method, device and system for storing functional modules based on a microservice gateway. Background Art

[0002] With the continuous increase in user demand, microservice architecture has gradually become the preferred architecture for software development. In the microservice architecture, the gateway provides a unified entrance for many microservices and has the ability to centrally process common non-business needs. The non-business needs processed by the gateway are often provided in the form of functional modules, such as service routing, traffic control, log monitoring, security authentication, etc.

[0003] In the microservice architecture, gateways are often deployed in multi-cluster mode. When deploying multi-cluster gateway services, each gateway needs to maintain its own functional modules. If the functional modules are lost due to abnormal events, the gateway service will be abnormal. For multi-cluster gateway services, the inconsistency of functional modules in different gateways in the same cluster or different clusters will also cause gateway service abnormalities. How to store functional modules to ensure the normal operation of gateway services has become an urgent problem to be solved.

[0004] In the existing functional module storage solution based on microservice gateway, the functional modules are stored in the gateway image file. However, due to the strong binding between the functional modules and the gateway, the iterative update of the former is inevitably accompanied by the redeployment of the latter, which makes the iterative update of the functional modules a high-risk operation. The abnormality of the functional modules will lead to the abnormality of the gateway service, and the normal operation of the gateway service cannot be guaranteed, and the high availability of the gateway service is difficult to guarantee.

[0071] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0072] The present application provides a method for storing functional modules based on a microservice gateway, wherein microservice is an architectural solution for software development. Microservice is a loosely coupled distributed architecture framework, each application consists of several independently deployable components, changes to a single component will not affect the entire application, and the development team can quickly build new components to meet changing business needs.

[0073] The present application embodiment provides a functional module storage solution based on a microservice gateway. Figure 1 The function module storage method based on the microservice gateway of the present application is described from the perspective of the gateway, such as Figure 1 As shown, the method may include:

[0074] Step S100: Send the imported legal function module to the file server.

[0075] Specifically, after the gateway imports a new functional module, it will perform a legitimacy check on the newly imported functional module. If the check fails, it will be re-imported. After each successful import of a legal functional module, the legal functional module will be sent to the file server so that the file server receives the functional module to implement storage of the functional module, generate an identifier of the functional module, and return the identifier.

[0076] Among them, the functional module is a general term for non-business functions in the gateway. The gateway centrally manages modules such as communication anti-counterfeiting, flow control, encryption and decryption. Each function is called a functional module. Customization of needs is achieved through the free combination of functional modules. The file server is a public file storage device. Any authorized user can read and write files on it. The file server is responsible for the management, transmission and reception of shared resources, and provides file sharing services for users in the network. In this application, the file server is shared between different clusters.

[0077] Step S110: Receive the identifier sent by the file server.

[0078] Step S120: Send the identifier to the network attached storage server in the cluster.

[0079] Specifically, after receiving the identifier of the function module sent by the file server, the identifier is sent to the network attached storage server in the cluster, so that the network attached storage server downloads the function module corresponding to the identifier from the file server to implement storage of the function module.

[0080] Among them, a network-attached storage server is a device connected to the network and has a data storage function. As a dedicated data storage server, the network-attached storage server completely separates the storage device from the server, and its storage efficiency is much higher than server storage. In this application, the network-attached storage server is mounted to the gateway cluster where it is located in the form of an attached disk, and all gateways in a single gateway cluster share the network-attached storage server in the cluster.

[0081] Step S130: When startup or reloading occurs, determine whether the local disk lacks a functional module.

[0082] Specifically, reloading refers to the process of reloading functional modules. During the reloading stage, the effective functional modules are loaded, and corresponding functions are provided to the outside world based on the functional modules owned. Therefore, when startup or reloading occurs, it should be determined first whether the functional modules are missing in the local disk to avoid gateway service abnormalities due to the missing functional modules or inconsistency with the functional modules stored in the local disk of other gateways.

[0083] If yes, execute the following step S140.

[0084] Step S140: Synchronize the missing functional modules from the network attached storage server to the local disk.

[0085] Specifically, since the missing functional modules may be stored in the network attached storage server in the cluster, the missing functional modules may be first synchronized to the local disk through the network attached storage server in the cluster.

[0086] If the synchronization fails, the following step S150 is executed.

[0087] Step S150: Synchronize the missing functional modules from the file server to the local disk.

[0088] Specifically, if synchronization from the network-attached storage server in the cluster fails, it means that the missing functional module is imported by the gateway in other clusters, so the gateway-attached storage server in this cluster does not store the missing functional module, or the network-attached storage server loses the missing functional module due to an abnormal event. Since the gateways in all clusters will send the imported functional modules to the file server, the file server stores all the functional modules. Therefore, in the event of a synchronization failure from the network-attached storage server, the missing functional module is synchronized from the file server.

[0089] Step S160: Load the function module from the local disk to provide corresponding functions externally.

[0090] Specifically, since the speed of loading function modules from a network-attached storage server and a file server is lower than the speed of loading function modules from a local disk, the present application preferentially loads function modules from a local disk to provide corresponding functions externally.

[0091] The functional module storage method based on the microservice gateway provided in the embodiment of the present application, when the gateway re-imports a legitimate functional module, the functional module will be stored in the network attached storage server and the file server in the cluster respectively. No matter which cluster the gateway is started or reloaded, it will be determined whether the local disk is missing the functional module. If so, the missing functional module is first synchronized to the local disk through the network attached storage server in the cluster. If the synchronization fails, the missing functional module is synchronized from the file server to the local disk, thereby avoiding gateway service anomalies caused by the loss of functional modules and gateway service anomalies caused by inconsistent functional modules of different gateways in the same cluster or different clusters, so that the gateway service can operate normally and ensure the high availability of the gateway service.

[0092] Furthermore, on the basis of ensuring the normal operation of the gateway service, the functional module will be loaded from the local disk to provide corresponding functions to the outside world, ensuring the startup efficiency of the gateway.

[0093] Optionally, in a function module storage method based on a microservice gateway provided in an embodiment of the present application, in order to implement the above step S130 to determine whether the local disk lacks a function module, the following steps may be performed after the identifier is sent to a network attached storage server in the cluster in the above step S120:

[0094] Step S121: Maintain the identification and attribute information of the functional module in a database.

[0095] Specifically, after receiving the identifier of the function module sent by the file server, the identifier and attribute information of the function module are maintained in the database, and all gateways in the gateway cluster can monitor the changes of the data in the database.

[0096] Based on this, before determining whether the local disk lacks a functional module in the above step S130, the following steps may be performed:

[0097] Step S122: Determine whether there is a changed functional module in the local disk according to the attribute information of the functional module in the database.

[0098] Specifically, each functional module has its corresponding attribute information. For functional modules that implement the same function, their attribute information may be the same or different. Since the functional module identifier and attribute information are maintained in the database whenever the functional module identifier is received from the file server, the database stores attribute information of functional modules with different functions and different attribute information of functional modules with the same functions. The attribute information of the functional modules in the database can be used to determine whether there are changed functional modules in the local disk. That is, for functional modules that implement the same function, if the attribute information in the local disk is inconsistent with the attribute information in the database, it means that the functional module has changed.

[0099] If not, directly execute step S130 to determine whether the local disk lacks a functional module; if so, execute the following step S123.

[0100] Step S123: Acquire the latest identification and attribute information of the changed functional module from the database and send them to the NAS server.

[0101] Specifically, since the database stores different identifications and attribute information of functional modules with the same functions, when there is a changed functional module in the local disk, the latest identification and attribute information of the changed functional module can be obtained from the database and sent to the network attached storage server in the cluster, so that the network attached storage server can register the changed functional module according to the latest identification and attribute information of the changed functional module.

[0102] Based on this, the process of determining whether the local disk lacks a functional module in the above step S130 may include:

[0103] Whether the local disk lacks a functional module is determined according to the registration status of the functional module by the network attached storage server.

[0104] Specifically, if there is a changed functional module in the local disk, the network attached storage server in the cluster where it is located will register the changed functional module. Therefore, it is possible to determine whether the local disk is missing a functional module based on the registration status of the functional module by the network attached storage server. If the functional module registered in the network attached storage server is consistent with the functional module in the local disk, it means that there is no lack of functional module in the local disk. If they are inconsistent, it means that there is a lack of functional module in the local disk.

[0105] Optionally, the network-attached storage server may store configuration information of the gateway, the configuration information including identification and attribute information of registered functional modules. Registration of functional modules by the network-attached storage server is to modify the identification and attribute information of the functional modules in the configuration information stored therein. Therefore, whether the functional modules are missing in the local disk may be determined by judging whether the identification and attribute information of the functional modules in the local disk are consistent with the identification and attribute information of the functional modules in the configuration information stored by the network-attached storage server. If they are consistent, it is determined that the functional modules are not missing in the local disk. If they are inconsistent, it is determined that the functional modules are missing in the local disk.

[0106] Optionally, in a method for storing a function module based on a microservice gateway provided in an embodiment of the present application, the process of maintaining the identification and attribute information of the function module in a database in step S121 may include:

[0107] The identification and abbreviation of the functional module, version information, update time, and the cluster to which it belongs are maintained in the database.

[0108] Based on this, the process of determining whether there is a changed functional module in the local disk according to the attribute information of the functional module in the database in step S122 may include:

[0109] It is determined whether the version information of the function module with the same abbreviation in the local disk is consistent with the latest version information in the database.

[0110] If they are consistent, it is determined that there is no changed functional module in the local disk.

[0111] If they are inconsistent, it is determined that there are changed functional modules in the local disk.

[0112] Specifically, functional modules with the same abbreviation are functional modules that implement the same function. Whether the functional module has changed can be determined based on the abbreviation and version information in the functional module attribute information. If the version information of the functional module with the same abbreviation in the local disk is inconsistent with the latest version information in the database, it means that the functional module has changed.

[0113] Optionally, based on the above embodiment, if the synchronization of the missing functional module from the network-attached storage server fails, it means that the network-attached storage server does not store the missing functional module, or the network-attached storage server loses the missing functional module due to an abnormal event. In order to avoid synchronization failure when the missing functional module needs to be synchronized from the network-attached storage server again, in a functional module storage method based on a microservice gateway provided in an embodiment of the present application, after synchronizing the missing functional module from the file server to the local disk in the above step S150, the following steps may be performed:

[0114] Step S151: Send the identifier of the missing functional module to the network attached storage server, so that the network attached storage server downloads the functional module corresponding to the identifier of the missing functional module from the file server for backup.

[0115] In some embodiments of the present application, in the event that synchronization of missing functional modules from a network-attached storage server fails, the network-attached storage server will download the missing functional modules from a file server for backup, so that when a gateway of a cluster where the network-attached storage server is located needs to synchronize the missing functional modules, it can be synchronized directly from the network-attached storage server without having to synchronize from the file server again, thereby improving the startup efficiency of the gateway.

[0116] The above embodiments are illustrated by means of specific examples. For example, in a certain microservice architecture, there are clusters A and cluster B. Cluster A includes gateway 1, gateway 2, and network-attached storage server 1. Cluster B includes gateway 3, gateway 4, and network-attached storage server 2. All gateways and network-attached storage servers in cluster A and cluster B share file server 1. It is assumed that the local disks in gateway 1, gateway 2, gateway 3, and gateway 4 and network-attached storage server 1, network-attached storage server 2, and file server 1 all store flow control modules. The flow control module is identified by identification 1, referred to as flow control, with version information 1.0, update time 2022 / 10 / 11, and the cluster to which it belongs is cluster A. The data stored in the database is (identification 1, flow control, 1.0, 2022 / 10 / 11, cluster A), and the configuration information in network-attached storage server 1 and network-attached storage server 2 is (identification 1, flow control, 1.0, 2022 / 10 / 11, cluster A).

[0117] Assume that gateway 3 has re-imported the flow control module. The re-imported flow control module is abbreviated as flow control, the version information is 2.0, the upload time is 2022 / 10 / 21, and the cluster it belongs to is cluster B. Gateway 3 sends the re-imported flow control module to file server 1. File server 1 receives and generates identifier 2, and returns identifier 2 to gateway 3. Gateway 3 maintains (identifier 2, flow control, 2.0, 2022 / 10 / 21, cluster B) and (identifier 2, flow control, 2.0, 2022 / 10 / 21, cluster A) to the database. At this time, the data stored in the database are: (identifier 2, flow control, 2.0, 2022 / 10 / 21, cluster A) and (identifier 2, flow control, 2.0, 2022 / 10 / 21, cluster B).

[0118] Taking gateway 1 as an example, when gateway 1 is started or reloaded, it is found that the version information of the flow control in the local disk is 1.0, and the latest version information of the flow control in the database is 2.0, indicating that the flow control function module has changed, updated from version 1.0 to 2.0. At this time, the latest flow control information is obtained from the database: (identifier 2, flow control, 2.0, 2022 / 10 / 21, cluster A), and the information is sent to the network-attached storage server 1. The network-attached storage server 1 modifies the configuration information (identifier 1, flow control, 1.0, 2022 / 10 / 11, cluster A) to (identifier 2, flow control, 2.0, 2022 / 10 / 21, cluster A) to register the changed flow control module and obtain the configuration in the network-attached storage server 1. The information is (identifier 2, flow control, 2.0, 2022 / 10 / 21, cluster A), and the information of the functional module in the local disk is (identifier 1, flow control, 1.0, 2022 / 10 / 11, cluster A). It is also a flow control module. The identification and attribute information of the two are inconsistent, indicating that the flow control module identified as identifier 2 is missing in the local disk. At this time, the module is synchronized through the network attached storage server 1, and the synchronization fails. The module is synchronized again through the file server 1. After the synchronization is successful, the flow control module identified as identifier 2 is loaded from the local disk to provide functions to the outside world, and identifier 2 is sent to the network attached storage server 1. The network attached storage server 1 downloads the flow control module corresponding to identifier 2 from the file server 1 according to identifier 2 for backup.
