.net核心nginx托管套接字不允许http发布

问题描述

我正在尝试建立一个具有http功能(包括http post功能)和Web套接字(例如signalR)的网站.我正在尝试使用nginx将这个网站托管在ubuntu服务器上.通常，在nginx上的设置是这样的:

I am trying to make a website that would have http functions including http post functions, and also web sockets (such as signalR). I am trying to host this website on an ubuntu server using nginx. Generally the set up is something like this on nginx:

server {
 listen 80;
 location / {
    proxy_pass http://localhost:5000;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection keep-alive;
    proxy_set_header Host $http_host;
    proxy_cache_bypass $http_upgrade;
 }
}

但是，我后来发现我需要添加proxy_set_header Connection "upgrade";才能使用websockets.但是，在.net核心项目中添加此行会导致所有http帖子请求显示400错误，如下所示.是否有一个既允许发布帖子又允许Web套接字的设置?

However, I later found that I need to add proxy_set_header Connection "upgrade"; in order to use websockets. However, adding this line in a .net core project results in all http post requests showing a 400 error as shown here 400 status error when posting form data in ASP.Net Core. Is there a set up that would allow both posts and web sockets?

推荐答案

使用$ http_connection而不是保持活动或升级

using $http_connection instead of keep-alive or upgrade

proxy_set_header Connection $http_connection;
