Nginx file uploading error 413 Request Entity Too Large

As a result, I used the Http packet capture tool (HttpDetect), as shown in the following figure.

The returned status is 413 Request Entity Too Large (nginx/1.2.1), and Baidu finds that this is a problem where nginx sets the packets allowed to be uploaded. This is in line with the above situation, there is no exception information in the background, because the request does not reach our tomcat at all. nginx finds that the request package is greater than the set value, and then returns 413 directly.

The solution is to set the nginx package size to an appropriate value, as shown in the following figure.
