python-Nginx WebSocket代理不断获取HTTP 301重定向

在过去的几天里,我一直在尝试让Nginx WebSocket代理正常工作,但是对于我一生来说,我无法使其正常工作.我遵循官方指南here,一直使用Python的websockets模块作为服务器,并使用npm软件包wscat作为客户端.从wscat到Python WebSocket后端的直接连接工作正常(来自浏览器的连接也是如此).但是,一旦我在Nginx中分层,它就无法正常工作,并继续为我提供标准的HTTP 301 重定向.

使用Nginx代理进行cURL调试输出：

$curl 'http://test.ws:8080/websocket' \
> -H 'Pragma: no-cache' \
> -H 'Origin: http://localhost:8080' \
> -H 'Accept-Encoding: gzip,deflate,sdch' \

没有Nginx代理的cURL调试输出：

我的Nginx(版本1.8.0)配置是这样的(websockets运行在端口8765的test.ws(127.0.0.1)上),并且Nginx正在本地主机的8080端口上侦听：

worker_processes  1;

error_log  logs/error.log debug;

events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    sendfile        on;
    keepalive_timeout  65;

    upstream ws {
        server 127.0.0.1:8765;
    }

    # map $http_upgrade $connection_upgrade {
    #     default upgrade;
    #     ''      close;
    # }

    server {
        listen       8080;
        server_name  test.ws;

        access_log  logs/localhost.access.log;

        location / {
            root   html;
            index  index.html index.htm;
        }

        location /websocket/ {
            proxy_pass http://ws;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";
        }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }

}

include servers/*;

有人知道我在这里做错了什么,为什么给我301 重定向？

最佳答案

事实证明,我的Nginx配置中的根位置节一直在干扰WebSocket代理传递隧道.有三种方法可以解决此问题.

>修改根位置节以完全匹配.

location = / {
    root   html;
    index  index.html index.htm;
}

>将根位置节重新排序为websocket位置节之后(首先是特定的,最后是普通的,就像重写匹配规则如何工作一样).
>在Nginx配置中删除以下根位置节将使其起作用.

location / {
    root   html;
    index  index.html index.htm;
}
