socket.io发出数据将断开客户端

编辑：我设法把我的问题简化成一些非常简单的事情：

这段代码没问题：

    socket.on('online', function(data){
        socket.emit("message", {"testField":"testData2"});
    });

这段代码断开了客户端的连接！：

    socket.on('online', function(data){
        socket.emit("message", {"testField":"testData"});
        socket.emit("message", {"testField":"testData2"});
    });

- (void) viewDidLoad
{
    [super viewDidLoad];
    socketIO = [[SocketIO alloc] initWithDelegate:self];
    [socketIO connectToHost:@"192.168.1.87" onPort:5000 withParams:@{@"token":@"avalidtoken"}];
}

经过深入研究，问题似乎归结为socket.io如何将多个消息组合到一个包中。

两期(#65#83)描述了手头的问题，并进一步详细讨论了这个问题。

总之，socket.io-objc库不处理这些特殊情况，并且始终假定数据包只包含单个消息。

�[packet_0 length]�[packet_0]�[packet_1 length]�[packet_1]�[packet_n

长度][packet_n]

目前，我认为onData只是将数据作为一个数据包来处理，但有时服务器会在一个响应中发送多个数据包。
