Socket.io error handling
提问by user1856728
I am having a problem with Socket.IO.
我在使用 Socket.IO 时遇到问题。
I am trying to reconnect the socket after the socket errors but it won't reconnect. Here is the code:
我试图在套接字错误后重新连接套接字，但它不会重新连接。这是代码：
socket = io.connect(host, options);
socket.on('connect', this.onConnect);
socket.on('error', function() {
//here i change options
socket = io.connect(host, options);
});
Why it doesn't it create the new connection? (The host and port are being kept constant and it works for the first connection).
为什么它不创建新连接？（主机和端口保持不变，它适用于第一次连接）。

Try adding the option { 'force new connection': true }to io.connect. It sounds like it isn't retrying the connection.
尝试将选项添加{ 'force new connection': true }到io.connect. 听起来它没有重试连接。
Socket IO won't reconnect to a host that it has already tried, unless you specify this option.
除非您指定此选项，否则套接字 IO 不会重新连接到它已经尝试过的主机。
Here is a snippet with the options hash specified in-line:
这是一个带有内嵌指定的选项哈希的片段：
io.connect(host, {
'force new connection': true
});
