[0063] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0064] The following describes the terms used in the embodiments of the present application.

[0065] Polling: A common web application communication method that continuously sends requests to query for updates on data or task status.

[0066] Websocket: A network protocol that provides full-duplex communication, allowing two-way communication over a single TCP connection and higher real-time performance than HTTP.

[0067] Multiplexing: A technique for transmitting multiple data streams simultaneously over a single TCP connection, which can reduce network overhead and improve communication efficiency.

[0068] Java server-side: refers to the server-side program that runs in the Java programming language.

[0069] Proxy: A type of middleware that acts as an intermediary between the client and the server, forwarding requests and responses and providing additional functionality and optimization.

[0070] HTTP request thread: A thread that processes HTTP requests in a web application. If too many polling requests occupy these threads, it will lead to resource waste and performance degradation.

[0071] Communication protocol: defines the rules and formats for data exchange between communicating parties.

[0072] Subscribe: Indicates that the client requests the server to update in real time or receive specific data.

[0073] API URL: This refers to the address of a specific API in a web application.

[0074] Polling interval: Specifies the time interval between polling requests, that is, how often polling is performed.

[0075] Metadata query: Use built-in monitoring and logging capabilities to query the current WebSocket connection status, subscribed interface information, connection time, and other information.

[0076] Heartbeat: A periodic message sent between the client and the server to ensure the activity and stability of the connection.

[0077] Data compression: By using compression algorithms to reduce the size of data transmission, network transmission efficiency is improved.

[0078] Protocol Buffers format: A data serialization format that can be used to efficiently compress and transmit data.

[0079] Authentication: The process of verifying the identity and permissions of a user or client to protect system and data security.

[0080] In traditional polling methods, frequent polling requests consume a large amount of client thread resources. Furthermore, when multiple different polling operations are in progress, multiple persistent connections must be maintained between the client and server, resulting in wasted resources and reduced performance. Furthermore, maintaining such polling code increases development complexity for front-end developers. For server-side developers, since polling requests often target more specific information within the server's API, supporting each specific polling request may require modifying the existing code and adding interfaces that adapt to polling requests, further increasing development complexity.

[0081] In order to solve the above problems, the embodiment of the present application proposes an information query method based on polling agent, such as Figure 1 As shown in , a front-end application runs in the client, and the front-end application can be in the form of a browser or a mobile client, and a back-end application runs on the server, and the server can be called an application server. The back-end application in the embodiment of the present application can be a Java server. The polling agent can be set in the server, that is, the polling agent is a service or module in the server, and the server includes the polling agent and the back-end application, or the polling agent can be independent of the server and there is a communication connection between the server. It should be noted that, in the case where the polling agent is set on the server, the interaction between the polling agent and the server described in the embodiment of the present application refers to the interaction between the polling agent and the back-end application in the server.

[0082] A first long connection can be established between the client and the polling agent. The first long connection supports full-duplex communication and multiplexing. Different polling can be achieved through the first long connection without establishing multiple connections. The client sends a subscription request to the polling agent to subscribe to the interface information that needs to be polled. The polling agent polls the corresponding interface in the server, and the client does not need to send requests frequently. For front-end developers, they only need to subscribe to the interface that needs to be polled according to the communication protocol, which greatly reduces the difficulty of development. For server developers, the polling agent queries the server's interface, and then returns the information in the interface query result required by the client to the client based on the interface query result. The server does not need to add interfaces to adapt to specific polling requests, and there is no need to change the original code.

[0083] Figure 2 This is a flow diagram of an information query method provided by an embodiment of the present application. Figure 1 .like Figure 2 As shown, the method includes:

[0084] S201. The client sends a subscription request to the polling proxy through a first persistent connection.

[0085] The subscription request includes one or more interface information to be queried, and the interface information includes the interface address and the polling interval. The first long connection supports full-duplex communication and multiplexing.

[0086] Each interface information in the subscription request indicates a polling object. The polling object can be the target interface or the target information in the target interface. The target interface is the interface for querying information on the server side. For example, the target interface is an interface for querying data, and the target information in the target interface is a data field returned by the interface for querying data. The target interface is an interface for querying task information, and the target information in the target interface is a certain task information returned by the interface for querying task information, such as task status. For the client, different polls can be subscribed through multiple interface information in one subscription request, or can be subscribed through multiple subscription requests. The first long connection supports multiplexing, and different subscription requests can be sent based on the first long connection.

[0087] The interface information includes the interface address and the polling interval. The interface address is used to indicate the target interface or the target information in the target interface, and the polling interval is used to indicate the time interval for the polling agent to query the server. The polling interval can be set according to specific needs, for example, the polling interval is 1s, 3s, 5s, 10s, 30s, 60s, etc. Optionally, the interface address includes path parameters and query parameters. For example, the interface address is the Uniform Resource Locator (URL) of the interface, and the URL contains path parameters and query parameters. The path parameters correspond to the interface for querying information provided by the server, that is, the target interface, and the query parameters correspond to part or all of the data returned by the target interface, that is, the target information. For example, the path parameters correspond to the product information interface on the server, and the query parameters correspond to the product inventory in the product information returned by the product information interface. For example, the path parameters correspond to the task details interface on the server, and the query parameters correspond to the task status in the task details returned by the task details interface.

[0088] S202: The polling agent sends an interface query request to the server based on the interface address and the polling interval.

[0089] Based on the target interface indicated in the interface address, the polling agent sends an interface query request to the server for the target interface. For example, if the interface address includes both path and query parameters, the polling agent sends an interface query request to the server based on the path parameter in the interface address and the polling interval in the interface information. For example, if the target interface corresponding to the path parameter is the product information interface and the polling interval is 10 seconds, the polling agent will send an interface query request to the server for this product information interface every 10 seconds.

[0090] S203: The server sends the interface query result to the polling agent.

[0091] The server receives the interface query request, obtains the corresponding information based on the interface query request, and returns it to the polling agent as the interface query result. For example, the target interface is the product information interface, and the interface query result of the product information interface includes product information such as product price and product inventory.

[0092] S204: The polling agent sends a subscription result to the client based on the interface address and the interface query result.

[0093] Based on the polled object indicated in the interface information and the interface query result returned by the server, the polling agent sends part or all of the information in the interface query result as a subscription result to the client via the first persistent connection. For example, if the interface address includes path parameters and query parameters, the polling agent determines the result in the interface query result corresponding to the query parameters as the subscription result based on the query parameters in the interface address, and sends the subscription result to the client.

[0094] For example, the target interface corresponding to the path parameter in the interface information is the product information interface, and the query parameter corresponds to the product inventory in the interface query result returned by the product information interface. After the server returns the interface query result containing product information such as product price and product inventory, the polling agent returns the product price as the subscription result to the client.

[0095] It can be understood that the polling agent sends an interface query request to the server according to the query interval. Accordingly, after receiving each interface query request, the server sends the corresponding interface query result to the polling agent. For the client, it will receive the subscription result sent by the polling agent based on the query interval.

[0096] The information query method provided in the embodiment of the present application implements polling based on the first long connection between the client and the polling agent. The first long connection supports full-duplex communication and multiplexing. Only one long connection needs to be maintained between the client and the polling agent to implement one or more polls, thereby reducing the overhead of connection establishment and disconnection. For each poll, the client only needs to send a corresponding subscription request to the polling agent, without frequently sending polling requests to the server, thereby reducing unnecessary polling requests, thereby improving communication efficiency and real-time performance, saving resources of the client and server, and avoiding performance degradation of the client and server.

[0097] Furthermore, by introducing a polling proxy, front-end applications are isolated from back-end application servers, providing more flexible architecture expansion and management. For front-end developers, they only need to subscribe to the polling interface according to the communication protocol, greatly reducing development complexity. For server-side developers, the polling proxy queries the server's existing interface and then returns the required information to the client based on the interface query results. The server does not need to add interfaces to adapt to specific polling requests, nor does it need to change the existing code.

[0098] Optionally, the first long connection in real time of this application is a WebSocket connection, and the polling agent is a Websocket agent, that is, the client sends a subscription request to the polling agent through the WebSocket connection, the Websocket agent sends an interface query request to the server based on the interface address and the polling interval, the server sends the interface query result to the polling agent, and the polling agent sends the subscription result to the client based on the interface address and the interface query result.

[0099] In the method of the embodiment of the present application, before S201, the following steps may be further included:

[0100] S200: Establish a first long connection between the client and the polling proxy.

[0101] The client can send multiple subscription requests to the polling proxy through the first long connection. That is, S200 is not necessarily executed before the client sends the subscription request. After establishing the first long connection through S200, the client can execute S201 multiple times to trigger subsequent corresponding steps.

[0102] When the first persistent connection is a WebSocket connection and the polling proxy is a WebSocket proxy, a WebSocket connection is established between the client and the WebSocket proxy. The process of establishing a WebSocket connection between the client and the WebSocket proxy can be found in related art and will not be described here. The authentication process can also be found in related art.

[0103] To ensure the viability of the first persistent connection, the client and the polling proxy use heartbeat messages to check and confirm. During communication, if an anomaly occurs, such as a connection loss, the polling proxy attempts to reestablish the connection. Alternatively, in the event of a service anomaly, the polling proxy can notify the client of the anomaly through the first persistent connection. For example, in a WebSocket connection, the client and WebSocket proxy use heartbeat messages to confirm the connection's viability. If the connection is lost, the WebSocket proxy can attempt to reestablish the WebSocket connection with the client.

[0104] Optionally, after sending a subscription request to the polling proxy, the client may also send a cancellation request through the first persistent connection according to actual circumstances to stop polling the corresponding interface.

[0105] Optionally, the client may also send a metadata query request to the polling proxy through the first persistent connection to query metadata information such as the subscribed interface, the last call time of the interface, and the last heartbeat time.

[0106] Optionally, to avoid polling from occupying resources for a long time, the polling agent disconnects the first persistent connection with the client when the subscription request exceeds a first preset duration or the first persistent connection is idle for longer than a second preset duration.

[0107] Wherein, "a subscription request exceeding a first preset duration" means that a first preset duration is set for a subscription request. If the client does not send a cancel subscription request after sending a subscription request for more than the first preset duration, the polling agent may trigger the disconnection of the first persistent connection to stop polling. "The first persistent connection being idle for longer than a second preset duration" means that no data is transmitted on the first persistent connection for longer than the second preset duration. In this case, the polling agent may trigger the disconnection of the first persistent connection to release network resources.

[0108] Optionally, in an embodiment of the present application, a data compression algorithm can be used in the messages transmitted between the client and the polling agent through the first long connection to reduce the amount of data transmitted and improve transmission efficiency. For example, the Protobuf format can be used for data transmission.
