Detailed Implementation
[0014] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, the embodiments of this application will be further described in detail below with reference to the accompanying drawings and specific implementation methods.
[0015] To facilitate understanding of the technical solution of this application, the technology involved in this application will be described below.
[0016] Currently, a common scenario for external network access to internal network is that users access applications running in the internal network environment through an integration platform deployed on the external network. To achieve this access, a proxy client deployed on the internal network receives a data access request from the external network. This data access request requests access to a specific application deployed on the internal network. Typically, the proxy server sends this data access request using a first application layer protocol. After receiving the data access request, the proxy client needs to determine whether the application being accessed supports the first application layer protocol. If not, the proxy client processes the data access request using a second application layer protocol supported by the application and then sends the processed data access request to the application.
[0017] However, due to the inherent limitations of the application layer protocol, it is impossible to transmit large file data, which also restricts some application scenarios.
[0018] Based on this, this application provides a data access method in which the proxy server and the proxy client communicate through the transport layer. In this way, the proxy client does not need to pay attention to the application layer protocol used by the proxy server, and it can support larger file data transfers, making it suitable for more intranet system connection scenarios.
[0019] The proxy server can be deployed on an external network integration platform. An integration platform is a tool or service used to integrate different systems, data, or applications, achieving information sharing and collaborative work through unified standards and interfaces. Its core functions include data integration, process automation, and cross-system connection management. The integration platform breaks down data barriers between systems through pre-built connectors, low-code tools, and other technologies, achieving unified governance across local and cloud systems. Specifically, the proxy server can be deployed in an Application Platform as a Service (aPaaS) platform, existing as a service component of the aPaaS platform. The aPaaS platform, also known as a low-code platform, is a cloud service platform that simplifies application deployment and management by providing scalable application infrastructure services.
[0020] In this embodiment, the integration platform can consolidate multiple systems belonging to an enterprise and provide a unified operation entry point. This allows users to complete corresponding operations through this unified entry point without having to access each system separately, thus improving business processing efficiency. The aforementioned unified operation entry point can be an entry point for accessing applications within the intranet. Users can trigger corresponding operations through this unified entry point to access applications within the intranet.
[0021] To facilitate understanding of the technical solution of this application, specific embodiments will be described below.
[0022] See Figure 1 The figure is a flowchart of a data access method provided in an embodiment of this application, as shown below. Figure 1 As shown, the method specifically includes the following steps: S101: The proxy server obtains a data access request, which is used to request access to the application data of the first application deployed on the intranet.
[0023] In one example, when the proxy server is deployed on an integration platform on the external network, in response to a user's operation triggered on that integration platform to access a first application deployed on the internal network, the first business component generates a data access request and sends it to the proxy server. Here, the first business component refers to a component corresponding to a specific business on the integration platform that needs to access the first application.
[0024] It should be noted that the integration platform can integrate functional components that can implement different business functions, and different business functions correspond to different business terminals. When a user accesses an application deployed on the intranet through a certain functional component on the integration platform, the business terminal corresponding to that functional component generates a data access request.
[0025] S102: The proxy server encapsulates the data access request and obtains the first message, which includes the data access request.
[0026] S103: The proxy server sends the first message to the proxy client, and the proxy client receives the first message accordingly.
[0027] In this embodiment, after receiving a data access request for the intranet, the proxy server encapsulates the request to obtain a first message, which is then sent to the proxy client deployed on the intranet. The first message is a transport layer message, and the data access request serves as its data payload.
[0028] In one example, when the proxy server and the proxy client communicate via the User Datagram Protocol (UDP), the proxy server will encapsulate the data access request using the UDP protocol to obtain the first message. Specifically, after the data access request is accessed at the transport layer, a UDP header (including source / destination ports, checksum, etc.) is added to form a UDP datagram.
[0029] In another example, when the proxy server and the proxy client communicate via the Transmission Control Protocol (TCP), the proxy server will encapsulate the data access request using the TCP protocol to obtain the first message. Specifically, after the data access request enters the transport layer, a TCP header (including source / destination ports, sequence number, acknowledgment number, etc.) is added to form a TCP segment.
[0030] Since TCP provides reliable data transmission, a TCP channel is established between the proxy server and the proxy client before communication. The proxy server then sends the first message to the proxy client through the TCP channel.
[0031] S104: The proxy client parses the first message and obtains the data access request.
[0032] S105: The proxy client sends a data access request to the first application, and the first application receives the data access request accordingly.
[0033] In this embodiment, after receiving the first message, the proxy client decapsulates the first message to obtain a data access request that can be directly processed by the first application, so that the first application can respond to the data access request. Then, the proxy client sends the data access request to the first application so that the first application can respond to the data access request.
[0034] In one example, if the first message is a TCP message, parsing a TCP message can include the following process: TCP header parsing: Checks the source / destination port numbers to determine the target application (i.e., the first application); verifies the sequence number and acknowledgment number to ensure data order; checks data integrity through checksums and discards erroneous segments.
[0035] Data reassembly: Segmented messages are arranged in order according to sequence number; received data is confirmed through a sliding window mechanism, triggering ACK feedback; when all segments arrive, they are merged into a complete data access request and sent to the target application.
[0036] In one example, if the first message is a UDP message, parsing the UDP message includes: Header processing: Directly parse the source / destination port number; no sequence number verification is required.
[0037] Data delivery: If checksums are enabled, data integrity is verified; otherwise, it is delivered directly to the first application.
[0038] S106: The first application sends a response message to the proxy client in response to the data access request, and the proxy client receives the response message accordingly.
[0039] In this embodiment, after receiving a data access request, the first application processes the data access request, obtains a response message, and sends the response message to the proxy client.
[0040] In one example, if the first application is a MySQL database, and the data access request is used to request the synchronization of data from the MySQL database to the external network, the response message includes the binary log file (Binlog) corresponding to the MySQL database. That is, in this implementation, the external network can directly read the Binlog corresponding to the database located on the internal network, thereby enabling large file data transfers.
[0041] S107: The proxy client encapsulates the response message and obtains the second message.
[0042] After receiving the response message, the proxy client encapsulates it using a transport layer protocol to obtain a second message. This second message is a transport layer message that includes the response message. Specifically, the response message serves as the data payload of the second message.
[0043] In one example, when the proxy server and the proxy client communicate via UDP, the proxy client will encapsulate the response message using the UDP protocol to obtain the second message.
[0044] In another example, when the proxy server and the proxy client communicate via TCP, the proxy client will encapsulate the response message using the TCP protocol to obtain the second message.
[0045] S108: The proxy client sends a second message to the proxy server, and the proxy server receives the second message accordingly.
[0046] S109: The proxy server parses the second message and obtains the response message.
[0047] In this embodiment, after receiving the second message, the proxy client sends it to the proxy server, thus achieving transport layer-based communication. Upon receiving the second message, the proxy server decapsulates it to obtain a response message, which is then sent to the corresponding service client.
[0048] For example, the response message includes the binary log file Binlog corresponding to the MySQL database located on the intranet. After obtaining the Binlog, the business side can realize data synchronization based on the Binlog.
[0049] As can be seen, the proxy server and the proxy client communicate through the transport layer. This means that the proxy client does not need to be concerned with the application layer protocol used by the proxy server, and it can support larger file data transfers, making it suitable for more intranet system connection scenarios.
[0050] For ease of understanding, see [link to relevant documentation]. Figure 2 The diagram illustrates an application scenario where a first business terminal 201, a second business terminal 202, and a proxy server 203 are deployed on an integration platform located on the external network, while a proxy client 301, a first application 302, and a second application 303 are deployed on the internal network. The first business terminal 201 accesses the first application 302, and the second business terminal 202 accesses the second application 303.
[0051] When the first business terminal 201 needs to access data in the first application 302, or when the second business terminal 202 needs to access data in the second application 303, the proxy server 203 and the proxy client 301 can access the data using the methods described above.
[0052] It should be noted that, Figure 2 The embodiments provided in this application are shown for the purpose of facilitating understanding of the solutions provided and do not constitute a limitation on the embodiments of this application. For example, a third application may also be deployed in the intranet 300, and the server 200 corresponding to the integration platform may also include a third business terminal corresponding to the third application.

[0057] S303: Send a first message to the agent client deployed on the intranet, so that the agent client can parse the first message, obtain the data access request, and send the data access request to the first application.
[0058] In one example, if a TCP channel is established between the proxy server and the proxy client, S302 can be implemented as follows: send the first message to the proxy client through the TCP channel.
[0059] In some implementations, the method further includes: receiving a second message sent by a proxy client, the second message being a transport layer message, the second message including a response message for the data access request; and parsing the second message to obtain the response message.
