尝试与socket.io聊天 这是我的服务器

这是我的客户代码：
var socket=io.connect('http://myib:80',{
'max re connection attempts':5,
'sync disconnect on unload':true
});
这是客户活动 '错误' 'reconnect_failed' '连接失败' 还有一些聊天活动等等 当socket尝试连接时给我这个警告： “websocket连接无效” 套接字连接一两次 有时插座断开连接 当尝试socket重新连接时给我同样的警告 当某些情况下可能开始插座5 6 7时，切断与其中一些插座的接触并再次尝试连接，但会发出相同的警告并继续尝试，直到重新加载页面才能连接
我正在使用最新版本的节点 我试试 io.set（“transports”，[“xhr-polling”，“jsonp-polling”]）; 请告诉我导致此问题及其解决方案的所有可能性。 感谢。
答案 0 :(得分：0)
您没有启用可能导致问题的所有传输。使用此：
io.set('transports', [
'websocket',
'flashsocket',
'htmlfile',
'xhr-polling'
'jsonp-polling',
]);
});
另外，我怀疑你在
中对服务器的引用var socket=io.connect('http://myib:80')
这是什么myib ???你已经定义了吗？您应该使用localhost或IP地址代替myib
