request.setTimeout(timeout[, callback])

• timeout <number> 请求超时前的毫秒数。
• callback <Function> 发生超时时要调用的可选函数。 与绑定到 'timeout' 事件相同。
• 返回: <http.ClientRequest>

一旦套接字被分配给这个请求并被连接，则 socket.setTimeout() 将被调用。

• timeout <number> Milliseconds before a request times out.
• callback <Function> Optional function to be called when a timeout occurs. Same as binding to the 'timeout' event.
• Returns: <http.ClientRequest>

Once a socket is assigned to this request and is connected socket.setTimeout() will be called.
