nignx causes repeated requests. The front-end console shows that nginx shows multiple processing
There is an interface for collecting device information, and the return time is relatively slow
The local win10 version nginx1.22.1 test is normal and can receive and return the results normally at one time
However, when testing on the company's test server, nginx1.19.0 shows multiple collection and processing in the nginx log, and multiple times in the background business, and then a network request is displayed in the front-end browser console, but there is no result, and finally a red mark is displayed But there is no response, and there is no configuration that lasts for 4-5 minutes
nginx configuration:
nginx version upgrade
1.19.0 upgrade to 1.22.1 still does not work
Finally, test the front-end interface of the request
Changed from 9000 to 9009, it works
Why is this? Does God know?
