默认 nginx client_max_body_size [英] Default nginx client_max_body_size

问题描述

我一直收到 nginx 错误:

413 请求实体太大

我已经能够将我的 nginx.conf 文件的服务器部分中的 client_max_body_size 更新为 20M，这已经解决了这个问题.但是，默认的 nginx client_max_body_size 是多少?

解决方案

client_max_body_size 指令的默认值为 1 MiB.

它可以在 http、server 和 location 上下文中设置——如在 大多数情况，此嵌套块中的指令优先于祖先块中的同一指令.

摘自 ngx_http_core_module 文档:

<块引用>

语法:client_max_body_size size；默认值:client_max_body_size 1m；上下文:http、服务器、位置

设置客户端请求正文的最大允许大小，在Content-Length"请求头字段.如果请求中的大小超过配置值，413(请求实体太大)错误返回给客户.请注意浏览器不能正确显示此错误.将 size 设置为 0 将禁用检查客户端请求正文大小.

不要忘记重新加载配置通过 nginx -s reload 或 service nginx reload 命令加上 sudo(如果有).

I have been getting the nginx error:

413 Request Entity Too Large

I have been able to update my client_max_body_size in the server section of my nginx.conf file to 20M and this has fixed the issue. However, what is the default nginx client_max_body_size?

解决方案

The default value for client_max_body_size directive is 1 MiB.

It can be set in http, server and location context — as in the most cases, this directive in a nested block takes precedence over the same directive in the ancestors blocks.

Excerpt from the ngx_http_core_module documentation:

Syntax:   client_max_body_size size;
Default:  client_max_body_size 1m;
Context:  http, server, location

Sets the maximum allowed size of the client request body, specified in the "Content-Length" request header field. If the size in a request exceeds the configured value, the 413 (Request Entity Too Large) error is returned to the client. Please be aware that browsers cannot correctly display this error. Setting size to 0 disables checking of client request body size.

Don't forget to reload configuration by nginx -s reload or service nginx reload commands prepending with sudo (if any).
