'connect' 事件

每次客户端请求 HTTP CONNECT 方法时触发。 如果未监听此事件,则请求 CONNECT 方法的客户端将关闭其连接。

除非用户指定 <net.Socket> 以外的套接字类型,否则此事件保证传入 <net.Socket> 类(<stream.Duplex> 的子类)的实例。

触发此事件后,请求的套接字将没有 'data' 事件监听器,这意味着需要绑定它才能处理发送到该套接字上的服务器的数据。

Emitted each time a client requests an HTTP CONNECT method. If this event is not listened for, then clients requesting a CONNECT method will have their connections closed.

This event is guaranteed to be passed an instance of the <net.Socket> class, a subclass of <stream.Duplex>, unless the user specifies a socket type other than <net.Socket>.

After this event is emitted, the request's socket will not have a 'data' event listener, meaning it will need to be bound in order to handle data sent to the server on that socket.
