在NGINX服務器上POST POST響應正文

我在帶有SSL證書的NGINX服務器上運行Node.js應用程序。我剛剛意識到，應用程序試圖返回到前端的所有POST/PUT請求都是空的;本質上，響應是一個空字符串。該應用程序在Heroku和本地環境中都可以正常工作，並且所有圖像和GET請求都應該如此解決。在NGINX服務器上POST POST響應正文

我期待JSON在我的HTTP響應中回來，無論請求是成功的還是有錯誤的。現在我得到一個空字符串。以下是我的回覆截圖，您會注意到內容長度標題完全丟失。

從本質上講，是有什麼不妥阻止我的HTTP響應回來空白我NGINX代理？

下面是我的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; 
    } 
}

位置塊的配置看起來繁瑣，因爲某些默認值很少需要更改，尤其是在調試期間沒有任何原因，所以一次更改多個值是非常複雜的錯誤。我建議禁止大量自定義指令，獲取Nginx訪問日誌，後端日誌，更新描述以使問題可以回覆。 – Anatoly

@Anatoly我更新了我的問題，添加了日誌，並簡化了我的配置。 –

HTTP 400是有效的響應代碼，它似乎是一個已知問題，可以通過更改後端配置來解決：https://github.com/socketio/socket.io/issues/1942#issuecomment-299764672 – Anatoly

在有一個版本Sails.js應用程序比0.11.X更大並且小於1.0時，res.badRequest()響應會在應用程序處於生產模式時從響應中除去數據。爲了解決這個問題，要麼升級Sails.js應用1.X以及如何做到這一點的documentation can be found here，或者你可以註釋掉api/responses/badRequest.js文件以下行：

// 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; 
    }
