[英]Socket.io events not received (nginx reverse proxy, server to client)
I have a nodejs socket.io app running under nginx reverse proxy. 我有一个在nginx反向代理下运行的nodejs socket.io应用程序。
My nginx configuration is as follows: 我的nginx配置如下:
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;
}
This seems to work, and my nodejs app picks up the connection fine. 这似乎可行,并且我的nodejs应用可以正常运行。 On the server side socket.io I have the following:
在服务器端socket.io上,我有以下内容:
io.of('/online').on('connection', function(socket){
This seems to work fine, and the 'connection' event is firing 这似乎工作正常,并且正在触发“连接”事件
The problem arises when I try to emit an event from the server to the client: 当我尝试从服务器向客户端发出事件时,就会出现问题:
socket.join("users");
io.sockets.in("users").emit("got_users",users);
The 'got_users' event is not being picked up by the client. 客户端未接收到“ got_users”事件。 On the client side I have the following:
在客户端,我有以下几点:
a4e.socket=io.connect('http://www.example.com/online');
This seems to work fine, but then: 这似乎工作正常,但是:
a4e.socket.on("got_users",function(online_users){
This doesn't pick up the "got_users" event, no matter what I try. 不管我尝试什么,这都不会发生“ got_users”事件。
Any help greatly appreciated. 任何帮助,不胜感激。
I finally figured this out, the following line: 我终于明白了,在下面的行:
io.sockets.in("users").emit("got_users",users);
Should be replaced with: 应替换为:
io.of("/online").in("users").emit("got_users",users);
Then it works. 然后就可以了。
