Question

使用nodejs创建网站时。在这个网站上我有一个页面可以上传图像到服务器。我在我的电脑上对它进行了测试，它的工作正常。我将它部署到服务器后它无法正常工作。我看了日志。我同时从访问和错误日志中获得了两个。

这是一个error.log

upstream prematurely closed connection while reading response header from upstream , client: xx.xx.xx.xx, server: example.com, request: "POST /admin/place/thumbnanil/upload HTTP/1.1", upstream: "http://127.0.0.1:3002/admin/place/thumbnanil/upload", host: "example.com", referrer: "https://example.com/admin/place/detail"

这是一个access.log

POST /admin/place/thumbnanil/upload HTTP/1.1" 502 583 "https://example.com/admin/place/detail"

这是我的nginx虚拟主机

upstream example {
    server 127.0.0.1:3002;
    keepalive 8;
}

server {
   listen                   80;
   server_name              example.com;
   return                   301 https://$server_name$request_uri;
}

server {
   listen                   443 ssl;
   server_name              example.com;
   ssl_certificate          /etc/letsencrypt/live/example.com/fullchain.pem;
   ssl_certificate_key      /etc/letsencrypt/live/example.com/privkey.pem;
   location / {
            proxy_pass      http://127.0.0.1:3002;
            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;

           proxy_buffering on;
           proxy_buffer_size 8k;
           proxy_buffers 2048 8k;
   }
}

我在AWS EC2上使用ubuntu 14.04。 NodeJS v4.4.7

这是我用于帖子的网址：https://example.com/admin/place/thumbnanil/upload

试试这个，

location / {
    proxy_set_header        Host $host;
    proxy_set_header        X-Real-IP $remote_addr;
    proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_set_header        X-Forwarded-Proto $scheme;

    proxy_pass          http://localhost:3002/;
    proxy_read_timeout  90;
    proxy_buffering     off;
    proxy_redirect      http://localhost:3002/  https://example.com/;

}

NodeJS无法上传文件导致上游过早关闭连接
