TECHNICAL FIELD

[0002] SSE (Server-Sent Events) is a technology that allows a server to send streaming data to a client, and the client can continuously transmit streaming data without further requests during data transmission. The conventional SSE technology has the following characteristics: one-way communication, persistent connection, HTTP-based, automatic reconnection and simple implementation. This data transmission method is suitable for scenarios such as push notification, real-time update and data stream.

[0003] Since the conventional SSE technology is a one-way communication technology, if the client wants to interrupt the content transmitted by the server at a certain time point, the client usually has no way to inform the server. Therefore, in the prior art, in order to interrupt the continuous transmission of streaming data, the network connection between the client and the server has to be forcibly closed. When the server discovers that the network is disconnected, an exception will be thrown, and the server needs to handle the exception, thereby affecting the performance of the server. SUMMARY

[0004] Embodiments of the present application provide an interrupt control method and device for SSE stream output, a server and a medium, aiming to actively interrupt the server's stream output on the premise of keeping the network connection between the client and the server.

[0027] Please refer toFigure 1 , Figure 1 is a flowchart of an interrupt control method of SSE streaming output provided by an embodiment of the present application. The interrupt control method of SSE streaming output is described in detail below. As shown in Figure 1 , the method comprises the following steps S110-S140.

[0028] S110, obtaining a data transmission interrupt request sent by a client, the data transmission interrupt request comprising a unique identifier of the client.

[0029] In an embodiment of the present application, for the convenience of understanding, the SSE technology is first described. SSE is a technology that allows a server to actively send data to a client. Unlike the traditional HTTP request-response mode, SSE provides a lightweight, one-way communication mechanism, enabling the server to push information to the client in real time. This technology is very suitable for scenarios that require real-time updates, such as stock quotes, real-time news push, online chat applications, etc. Specifically, as shown in Figure 2 , the SSE technology has the following characteristics: one-way communication: SSE is one-way, only data can be sent from the server to the client. Persistent connection: once the client connects to the server, the connection will remain open until the client or server explicitly closes it. Based on HTTP: SSE uses a standard HTTP connection, but uses a special Content-Type (text / event-stream) to identify the data stream. Automatic reconnection: if the connection is disconnected, most browsers will automatically try to reconnect. Simple implementation: the client uses the EventSource interface of JavaScript to receive data, while the implementation of the server depends on specific server technology.

[0030] Since the SSE technology adopts a one-way communication mode, if the streaming output of the server needs to be interrupted, the server needs to open an interface, and the client accesses this interface by creating a new thread. The client carries the unique identifier of the client itself, such as "id": 1001, when sending the data transmission interrupt request. The server obtains the request and starts to execute the subsequent steps.

[0031] S120, querying a stored corresponding data transmission control field according to the unique identifier of the client and updating the data transmission control field, the data transmission control field being used to identify whether to interrupt the streaming output of the current data.

[0032] In an embodiment of the present invention, after a server receives a data transmission interruption request from a client, it queries a database based on the unique identifier of the client carried in the data transmission interruption request, and queries the corresponding data transmission control field. Specifically, the data transmission control field is used to indicate whether to interrupt the current streaming output. When the data transmission control field "isInterrupted" is "true", the current streaming output is interrupted; when the data transmission control field "isInterrupted" is "false", the current streaming output continues. The data transmission control field defaults to "false" when it is created. Therefore, in response to the data transmission interruption request, when the server queries "isInterrupted" to be "false", it needs to update "false" to "true", thereby allowing the current streaming output to be interrupted when the server makes subsequent queries. It should be noted that the database used to store data transmission control fields can replace various types of caches (such as Redis, Memcached, memory cache, etc.), message queues (such as RabbitMQ, Kafka, RocketMQ, etc.), MQTT (Message Queuing Telemetry Transport)-based middleware, and shared network file storage (such as Alibaba Cloud OSS and other cloud services) and other persistent networked components.

[0033] In one embodiment, the method further includes: obtaining an SSE data transmission request sent by a client, the SSE data transmission request including a unique identifier of the client, and streaming data to the client after a connection is established; and querying a currently stored corresponding data transmission control field based on the unique identifier of the client during data streaming with the client. This step is used to establish streaming data transmission between the client and the server. After the client and the server have established data streaming, the server periodically queries the currently stored corresponding data transmission control field based on the unique identifier of the client. Specifically, the step of querying the currently stored corresponding data transmission control field based on the unique identifier of the client during data streaming with the client further includes: querying the currently stored corresponding data transmission control field based on the unique identifier of the client after each round of streaming data transmission with the client. In this embodiment, to ensure normal data transmission each time, a field query is performed after each data transmission from the server to the client. That is, when the server sends streaming data to the client, after each stream of data is sent, the server queries a data transmission control field "isInterrupted" in the database.

[0034] S130: Determine whether to interrupt the streaming output of the current data according to the query result of the data transmission control field.

[0035] In the embodiment of the present application, the initial value of the data transmission control field is false, and the step of judging whether to interrupt the current data streaming output according to the query result of the data transmission control field further comprises: if the data transmission control field is true, interrupting the current data streaming output; and if the data transmission control field is false, continuing the current data streaming output.

[0036] Specifically, the server queries the corresponding data transmission control field "isInterrupted" in the database according to the unique identifier of the client, and the value of the data transmission control field is "true" or "false". When the server queries that the current corresponding data transmission control field "isInterrupted" is "true", the server interrupts the current streaming output and simultaneously interrupts the SSE connection with the client. When the server queries that the current corresponding data transmission control field "isInterrupted" is "false", the current streaming output is continued, and the next query is waited for. As can be seen, in the present scheme, the streaming output is interrupted first, and then the connection between the server and the client is disconnected. The server does not generate an error, and the graceful end of the output can ensure that the server performance is not affected, which is suitable for scenarios to improve service experience.

[0037] In one embodiment, after the step of judging whether to interrupt the current data streaming output according to the query result of the data transmission control field, the method further comprises: when the streaming output with the client is interrupted, disconnecting the connection with the client and restoring the data transmission control field corresponding to the unique identifier of the client to false, to wait for the next re-establishment of data transmission. Specifically, when the server responds to the interruption request of the client, the connection with the client is disconnected. Since the data transmission control field "isInterrupted" corresponding to the client has been updated to "true" before, if the client needs to re-establish the SSE transmission with the server subsequently, the corresponding transmission control field "isInterrupted" needs to be restored to "false" after the network interruption between the server and the client. In this way, it is ensured that the subsequent re-establishment of the SSE streaming data transmission between the client and the server can be performed normally.

[0038] In the embodiment of the present application, the server queries the stored data transmission control field when performing data streaming transmission with the client, judges whether to interrupt the streaming transmission with the client according to the value of the field, and the client can modify the value of the data transmission control field through a data transmission interruption request, thereby actively interrupting the streaming output of the server, and no network disconnection or other abnormalities occur in the whole process of actively interrupting the streaming output, thereby not affecting the performance of the server.

[0039] In one embodiment, referring to Figure 3 The flowchart of the interruption control method of the SSE streaming output is shown, and the specific implementation steps are as follows:

[0040] First, the user requests the SSE interface on the client side, and the client creates a thread to call the SSE interface of the server. Among them, the client carries the unique identification of the client when calling the SSE interface, such as the parameter {“id”:1001}.

[0041] Then, when the server receives the interface request sent by the client to establish a connection, it starts to execute the business logic, that is, the server starts to output the first stream data. During the data transmission process, the server will query the data transmission control field of id 1001 in the database according to the streaming output situation, and judge whether the data transmission control field “isInterrupted” field is “true”. If the query “isInterrupted” field is “true”, the data transmission is interrupted and the connection with the client is disconnected, if the query “isInterrupted” field is “false”, the data streaming transmission is continued.

[0042] When the user needs to actively interrupt the server streaming transmission, another thread is created through the client to request a HTTP interface of the server, while carrying the unique identification of the client, such as the parameter {“id”:1001}.

[0043] Then, after the server receives the parameter {“id”:1001}, it updates the corresponding data transmission control field “isInterrupted” in the database, and updates the value of the data transmission control field “isInterrupted” to “true”. It should be noted that when the server and the client establish a connection to start streaming transmission, the server can create the data transmission control field “isInterrupted” corresponding to the client in the database, and the default value of this field when created is “false”. Subsequently, when the server queries the “isInterrupted” value corresponding to the client id in the database during data transmission, it is directly ended if the “isInterrupted” value is updated to “true”, that is, the client can gracefully interrupt the server's streaming output, without producing network disconnection exceptions, effectively reducing the server load, and can be applied to streaming interruption of various projects using SSE technology (such as large language models, etc.).

[0044] In one embodiment, the data transmission interruption request further comprises an interruption timing parameter, and the method further comprises: when it is queried that the data transmission of the client needs to be interrupted, timing control is performed on the time of interrupting the data transmission according to the interruption timing parameter.

[0045] In the embodiment of the application, when the user interrupts the streaming output of the server through the client, the interruption can be controlled through different service variables. Specifically, the data transmission interruption request further comprises an interruption timing parameter. For example, the parameter countDown:5 is carried, which indicates that the server is told to disconnect after 5 seconds of countdown, and the server can be allowed to perform some service processing before disconnection. When the server queries that the data transmission of the client needs to be interrupted, the interruption timing parameter countDown:5 is obtained, and the data transmission is disconnected after 5 seconds of countdown.

[0046] In the embodiment, the timing of interruption is controlled through the interruption timing parameter, and the server can be ensured to have sufficient time to perform other services before interrupting the streaming output.

[0047] In one embodiment, the data transmission interruption request further comprises an interruption trigger condition parameter, and the method further comprises: querying the state bit corresponding to the current server according to the terminal trigger condition parameter, and disconnecting the streaming output of the client when the state bit meets the trigger condition.

[0048] In the embodiment of the application, when the user interrupts the streaming output of the server through the client, the interruption can be further controlled through the setting of the trigger condition parameter. For example, when the client sends the data transmission interruption request server interface through a thread, some state values dependent on the server are carried, such as isStatus:true, which indicates that the server is told to disconnect when a certain state bit (isStatus) of the server service side is true. Alternatively, the server needs to monitor the current usage rate, and the streaming output is interrupted when the usage rate exceeds a certain threshold. When the server obtains the request, the current state bit is checked, and the streaming output of the client is interrupted when the current state bit meets the trigger condition.

[0049] In the embodiment, the timing of interrupting the streaming output of the server is further controlled through the monitoring of the state value of the server, and the streaming output of the server can be interrupted more flexibly.
