Question

我在带有SSL证书的NGINX服务器上运行Node.js应用程序。我刚刚意识到应用程序尝试返回前端的所有POST / PUT请求都是空的;本质上响应是一个空字符串。该应用程序在本地环境以及Heroku中运行良好，所有图像和GET请求都可以解决。

我期待JSON回到我的HTTP响应中，无论请求是成功还是有错误。现在我得到一个空字符串。下面是我的回复的屏幕截图，您会注意到内容长度标题完全丢失。

基本上，我的NGINX代理是否有问题阻止我的HTTP响应变回空白？

以下是我的NGINX配置文件

server {
    listen 80;

    server_name blah.com;
    rewrite ^/(.*) https://blah.com/$1 permanent;
}
server {
    # SSL configuration
    #
    listen 443 ssl default_server;
    ssl_certificate XXX;
    ssl_certificate_key XXX;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_prefer_server_ciphers on;
    ssl_ciphers 'EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH';

    root /var/www/html;

    # Add index.php to the list if you are using PHP
    index index.html index.htm index.nginx-debian.html;

    server_name blah.com;

    location / {
            proxy_pass http://127.0.0.1:8080;
            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;
    }
}

Bellow是应用程序生成的访问日志：

在版本大于0.11.X且小于1.0的Sails.js应用程序中，res.badRequest()响应在应用程序处于生产模式时将数据从响应中剥离。要解决此问题，请将Sails.js应用程序升级到1.X，将documentation can be found here升级为如何执行此操作，或者可以在api/responses/badRequest.js文件中注释掉以下行：

  // Only include errors in response if application environment
  // is not set to 'production'.  In production, we shouldn't
  // send back any identifying information about errors.
  if (sails.config.environment === 'production') {
    //data = undefined;
  }

在NGINX服务器上POST响应体为空
