Question

我正在尝试setup websocket proxy来定义位置（/ws），但是它不起作用。但是使用root（/）作为位置对我有用。

有效：

server {
    listen       80;
    server_name  localhost;

    location / {
        proxy_pass http://echo.websocket.org;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_buffering off;
    }
}

不起作用：

server {
    listen       80;
    server_name  localhost;

    location /ws {
        proxy_pass http://echo.websocket.org;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_buffering off;
    }
}

我还检查了服务器响应：

curl -i -N -H "Connection: Upgrade" -H "Upgrade: websocket" -H "Host: localhost:8888" -H "Origin: http://localhost:8888/ws" http://localhost:8888/ws

我在做什么错了？

我认为这里的问题在于模式匹配。首先，您必须从客户端将Websocket网址指定为 ws：// localhost：80 / ws / 请注意，您必须在网址末尾输入（ / ），并在NGINX服务器端以这种方式进行配置：

server {
listen       80;
server_name  localhost;

location /ws/ {
    proxy_pass http://echo.websocket.org;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_buffering off;
}}

请注意，您必须提供 / ws / 位置参考。
