项目用的SSE请求方法和@microsoft/fetch-event-source有什么区别吗

[Gijela]

hello，请教个问题，我看到项目中自己封装了个 SSE 的调用方法，想问下这个方法和 @microsoft/fetch-event-source 库有什么区别？是基于它完善的吗？
我在使用 @microsoft/fetch-event-source 的时候偶现一个问题，流式请求连接建立成功后并且返回了一段时间的流消息，会偶现触发 onerror 使得连接断开，但是查后端日志，发现是一直在发送流消息，想问下这个问题是 fetch-event-source这种库引起的吗？使用本项目中的调用方法可以解决这个问题吗？

hello, please ask a question. I saw that I encapsulate a SSE call method in the project. I would like to ask what is the difference between this method and the @microsoft/fetch-event-source library? Is it perfected based on it?
When I was using @microsoft/fetch-event-source, I encountered a problem. After the streaming request connection was successfully established and a stream message returned for a period of time, onerror was occasionally triggered to cause the connection to be disconnected. However, when I checked the backend log, I found that the stream message was being sent. I would like to ask whether this question was caused by a library like fetch-event-source? Can this problem be solved using the calling method in this project?

Hello, @Gijela! I'm here to help you with any bugs, questions, or contributions you may have. Let's see what's going on with your project.

I found a similar discussion regarding the SSE method and the @microsoft/fetch-event-source library, which is currently unsolved. You can view it here ^[1].

Regarding your question about the differences between the custom SSE method in the project and the @microsoft/fetch-event-source library, I couldn't find specific details on the implementation differences or error handling mechanisms within the repository. However, the fetchSSE.ts file in the project includes various dependencies and imports that support its functionality, such as handling streaming data, managing errors, and ensuring smooth animations and updates in the chat framework ^[2][3].

If you're experiencing issues with the @microsoft/fetch-event-source library, such as the connection unexpectedly triggering onerror, it might be worth trying the custom SSE method in the project to see if it resolves the problem. Unfortunately, without more detailed information on the custom implementation, it's difficult to determine if it will address the specific issue you're encountering.
