Nginx为什么不将协议更改为WebSocket? [英] Why isn't Nginx changing the protocol to WebSocket?

问题描述

我正在尝试运行Laracvel-echo.

I am trying to run Laracvel-echo.

主机配置:

location /socket.io {
    proxy_pass http://127.0.0.1:6002/;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "Upgrade";
    proxy_set_header Host $host;
}

我用Socat捕获标题:

I catch headers with Socat:

socat -v TCP-LISTEN:6002,fork TCP:127.0.0.1:6001

在我的DEV服务器上，我发现一切正常，协议正在更改(HTTP/1.1 101交换协议):

On my DEV server, I see that everything is ok, the protocol is changing (HTTP/1.1 101 Switching Protocols):

2020/10/22 13:51:36.147102  length=175 from=0 to=174
HTTP/1.1 101 Switching Protocols\r
Upgrade: websocket\r
Connection: Upgrade\r
Sec-WebSocket-Accept: yU0AKhFOQaw5j9cQS8oq2bjx1pw=\r
Sec-WebSocket-Extensions: permessage-deflate\r

但是在PRODUCTION服务器中，我看到GET协议(GET/socket.io HTTP/1.1):

But in PRODUCTION server i see GET protocol (GET /socket.io HTTP/1.1):

 2020/10/22 13:50:34.161919  length=588 from=0 to=587
GET /socket.io HTTP/1.1\r
Upgrade: websocket\r
Connection: Upgrade\r
Host: localhost:6002\r
Pragma: no-cache\r
Cache-Control: no-cache\r

Origin: chrome-extension://pfdhoblngboilpfeibdedpjgfnlcodoo\r
Sec-WebSocket-Version: 13\r
Accept-Encoding: gzip, deflate\r
Accept-Language: ru-RU,ru;q=0.9,en-US;q=0.8,en;q=0.7\r
Sec-WebSocket-Key: rq5CaFXEzZ/vWSnOJ5H3PA==\r
Sec-WebSocket-Extensions: permessage-deflate; client_max_window_bits\r

我的问题与此有关:带有Laravel-echo-的WebSocket-服务器:502错误的网关NGINX问题还是我错了?

My question is related to this: WebSocket with Laravel-echo-server: 502 Bad gateway Is the NGINX problem or am I wrong?

请帮助我！)

推荐答案

我不知道问题出在哪里，但我找到了解决方案.我做了很多更新:将Nginx更新为1.19.1，可能安装了一些其他模块.npm不是全局安装的，而是本地安装的.而且有效...

I don't know what the problem is, but I found a solution. I've updated a lot: updated Nginx to 1.19.1, possibly installed some additional modules. Installed npm not globally, but locally. And it worked ...

注意:仅当您编写 location/socket.io.
