用 nodejs 配置 nginx，不支持上传文件 POST 请求？

Question

我正在尝试使用 nodejs（sails.js 框架）配置 nginx。 Nginx 在 80 端口监听请求并传递到 8080。除了上传文件 post 请求之外，所有请求都可以正常工作（都是 post）。

下面是我的 nginx 配置文件：

events {
    worker_connections 768;
    # multi_accept on;
}

http {

    ##
    # Basic Settings
    ##

    sendfile on;
    tcp_nopush on;
    tcp_nodelay on;
    keepalive_timeout 65;
    types_hash_max_size 2048;
    # server_tokens off
        upstream node {
         # One failed response will take a server out of circulation for 20 seconds.
         server localhost:8080 fail_timeout=20s;
                 keepalive 512;
    }
        server {
         listen 80 default_server;
         listen 8191;
         listen 443 ssl;
         ssl    on;
         ssl_certificate    /home/ubuntu/APP/cert.pem;
         ssl_certificate_key     /home/ubuntu/APP/key.pem;
         server_name localhost;

         location / {
            proxy_pass https://localhost:8080;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection 'upgrade';
            proxy_set_header Host $host;
            proxy_cache_bypass $http_upgrade;
            # define buffers, necessary for proper communication to prevent 502s
        proxy_buffer_size 128k;
        proxy_buffers 4 256k;
        proxy_busy_buffers_size 256k;
            }
        }
    # server_names_hash_bucket_size 64;
    # server_name_in_redirect off;

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

    include /etc/nginx/conf.d/*.conf;

您是否尝试取消注释这些行？

#passenger_root /usr;
#passenger_ruby /usr/bin/ruby;
