This article describes how to solve the 413 Request Entity Too Large problem on nginx, Apache, and IIS servers.

The reason for this problem is that the request entity is too long. Generally, when a Post request is sent, the Body contains too much Post data,
The uploaded files are too large and contain a large amount of POST data.

Add the client_max_body_size setting in nginx. conf. The default value is 1 MB, which can be increased to 8 MB to increase the file size limit. Of course, you can set a bigger point.
# Modify the following configurations in the http, server, or location segments:

# Set client body size to 8 M #
Client_max_body_size 8 M;

Ii. Apache server
Modify the LimitRequestBody configuration in the Apache configuration file. If it is a virtual host, contact the space provider for help.
