Django attempts SSE log push and analysis of AssertionError: Hop-by-hop headers not allowed exception

I found that there are errors during the process: Traceback (most recent call last): File “D:\Software\Anaconda3\lib\wsgiref\handlers.py”, line 137, in […]

WebFlux exception handling: onErrorReturn and onErrorResume
1 Origin I’m learning WebFlux recently, Some problems are encountered when handling exceptions. For example, exceptions thrown directly by Java cannot be directly caught by onErrorReturn and onErrorResume. However, exceptions after methods such as map or flatMap can be caught directly. So, I conducted a test and found that the exceptions that can be caught […]
