Question

我将使用socket.io与node.js服务器进行客户端python。我找到了socketIO-client，看起来不错。

当我启动我的客户端时，他从服务器接收消息（连接了多少客户端）。但几秒钟后，就会出现异常：

(slevin@localhost 52)./test.py  There is 2 client currently connected Traceback (most recent call last):   File "./test.py", line 9, in <module>
    socketIO.wait()   File "/usr/lib/python2.7/site-packages/socketIO_client/__init__.py", line 175, in wait
    self._process_events()   File "/usr/lib/python2.7/site-packages/socketIO_client/__init__.py", line 192, in _process_events
    for packet in self._transport.recv_packet():   File "/usr/lib/python2.7/site-packages/socketIO_client/transports.py", line 80, in recv_packet
    for packet_text in self.recv():   File "/usr/lib/python2.7/site-packages/socketIO_client/transports.py", line 150, in recv
    yield self._connection.recv()   File "/usr/lib/python2.7/site-packages/websocket.py", line 596, in recv
    opcode, data = self.recv_data()   File "/usr/lib/python2.7/site-packages/websocket.py", line 606, in recv_data
    frame = self.recv_frame()   File "/usr/lib/python2.7/site-packages/websocket.py", line 637, in recv_frame
    self._frame_header = self._recv_strict(2)   File "/usr/lib/python2.7/site-packages/websocket.py", line 746, in
_recv_strict
    bytes = self._recv(shortage)   File "/usr/lib/python2.7/site-packages/websocket.py", line 732, in _recv
    raise WebSocketTimeoutException(e.message) websocket.WebSocketTimeoutException: timed out

我没有找到引发此异常的地方。

备注：如果我连接了很多客户端，没有问题，所以我认为“socketIO.wait（）”就是问题所在。为什么我的客户超时？

这是我的客户代码：

    #!/usr/bin/python                                                                                       
from socketIO_client import SocketIO

def nbclient_update(*args):
    print 'There is %d client currently connected' % (args[0])

with SocketIO('localhost', 80) as socketIO:
    socketIO.on('nbClient', nbclient_update);
    socketIO.wait()

这是我的服务器代码：

var express = require('express');
var http = require('http');
var fs = require('fs');

var app = express();
var nbClient = 0;

app.get('/', function(req, res) {
    fs.readFile('./index.html', 'utf-8', function(error, content) {
        res.writeHead(200, {"Content-Type": "text/html"});
        res.end(content);
    });
});

// Server load                                                                                          
var server = http.createServer(app);

// Socket.io load                                                                                       
var io = require('socket.io').listen(server);
io.set('destroy upgrade', false);

io.sockets.on('connection', function (socket) {
    ++nbClient;
    socket.emit('nbClient', nbClient);
    socket.broadcast.emit('nbClient', nbClient);

    socket.on('disconnect', function() {
        --nbClient;
        socket.broadcast.emit('nbClient', nbClient);
    });
});

server.listen(80, "0.0.0.0");

Cound很高兴你有个主意。非常感谢。
