未收到 Socket.io 事件(nginx 反向代理，服务器到客户端) [英] Socket.io events not received (nginx reverse proxy, server to client)

问题描述

我有一个在 nginx 反向代理下运行的 nodejs socket.io 应用.

I have a nodejs socket.io app running under nginx reverse proxy.

我的nginx配置如下:

My nginx configuration is as follows:

location ~ ^/(online|socket\.io) {
        proxy_pass http://localhost:8888;
        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;
    }

这似乎有效，我的 nodejs 应用程序连接正常.在服务器端 socket.io 我有以下内容:

This seems to work, and my nodejs app picks up the connection fine. On the server side socket.io I have the following:

io.of('/online').on('connection', function(socket){

这似乎工作正常，并且 'connection' 事件正在触发

This seems to work fine, and the 'connection' event is firing

当我尝试从服务器向客户端发出事件时出现问题:

The problem arises when I try to emit an event from the server to the client:

socket.join("users");
io.sockets.in("users").emit("got_users",users);

'got_users' 事件没有被客户端接收.在客户端，我有以下内容:

The 'got_users' event is not being picked up by the client. On the client side I have the following:

a4e.socket=io.connect('http://www.example.com/online');

这似乎工作正常，但随后:

This seems to work fine, but then:

a4e.socket.on("got_users",function(online_users){

无论我尝试什么，这都不会触发got_users"事件.

This doesn't pick up the "got_users" event, no matter what I try.

非常感谢任何帮助.

推荐答案

我终于想通了，下面这行:

I finally figured this out, the following line:

io.sockets.in("users").emit("got_users",users);

应替换为:

io.of("/online").in("users").emit("got_users",users);

然后就可以了.
