Nginx 忽略 /etc/nginx/conf.d/ 中 nginx.conf 中定义的 client_max_body_size

Question

我有一个通过 django 服务器公开的上传 api。每当我尝试上传任何超过 1MB 的文件时，我都会从 nginx 收到一条错误消息，提示“413 Entity too large”

我有一个名为 nginx.conf 的配置文件，其中 client_max_body_size 在目录 /etc/nginx/conf.d 中设置为 75M 在/etc/nginx/nginx.conf 文件中，我将include /etc/nginx/conf.d/*.conf; 作为http 块的最后一行，那么为什么我会看到这个错误？

我已经按照https://uwsgi-docs.readthedocs.io/en/latest/tutorials/Django_and_nginx.html?highlight=client_max_body_size 使用 uWSGI 和 Nginx 配置 Django 和 webserver

nginx 版本 1.15.6

和site.conf文件在/etc/nginx/conf.d/

    # max upload size

    # Django media
    location /media  {
        alias /my-app/code/media;  # your Django project's media files - amend as required
    }

    # Finally, send all non-media requests to the Django server.
    location / {
        uwsgi_pass  django;
        include     /my-app/code/uwsgi_params; # the uwsgi_params file you installed
    }
}

Answer 1

确保将client_max_body_size 添加到服务器块

http {
    server {
        client_max_body_size 20M;
        listen       80;
        server_name  test.com;
    }
}

最重要的是通过以下方式使您的配置工作：

sudo /etc/init.d/nginx reload
