如果主体太大，Nginx/UWSGI/FLASK POST超时

Question

curl -H "Content-Type: application/json" -X POST http://10.4.5.168:5002/test -d '{"test": "test"}'

很好用。但是，如果我发布了一个更大的json文件，我会得到一个504：Gateway超时。

curl -H "Content-Type: application/json" -X POST http://10.4.5.168:5002/test -d @some_6mb_file.json

我感觉Nginx和Uwsgi之间的通信有一个问题，但我不知道如何解决它。

编辑：我跳入docker容器并手动重启nginx以获得更好的日志记录。我收到以下错误：

user  nginx;
worker_processes 1;

error_log  /var/log/nginx/error.log warn;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/conf.d/*.conf;
}
daemon off;

/etc/nginx/conf.d/nginx.conf：

server {
    listen 80;
    location / {
        try_files $uri @app;
    }
    location @app {
        include uwsgi_params;
        uwsgi_pass unix:///tmp/uwsgi.sock;
    }
    location /static {
        alias /app/static;
    }
}

/etc/nginx/conf.d/upload.conf：

client_max_body_size 128m;
client_body_buffer_size 128m;

我在代理aiohttp（Python）应用程序时遇到了这种行为。

在我的例子中，在代理的位置块中，我需要禁用缓存：

从块中移除：

proxy_set_header Upgrade $http_upgrade;
proxy_set_header Connection 'upgrade';
proxy_set_header Host $host;
proxy_cache_bypass $http_upgrade;

  server {
    listen 80;
    location / {
        try_files $uri @app;
    }
    location @app {
      proxy_set_header Host $http_host;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_redirect off;
      proxy_buffering off;
      proxy_pass http://myapp;
    }
    location /static {
        alias /app/static;
    }
}
