request.setTimeout(msecs, callback)

• msecs <number>
• callback <Function>
• 返回：<http2.Http2ServerRequest>

将 Http2Stream 的超时值设置为 msecs。如果提供了回调函数，则会将其作为监听器添加到响应对象的 'timeout' 事件上。

【Sets the Http2Stream's timeout value to msecs. If a callback is provided, then it is added as a listener on the 'timeout' event on the response object.】

如果没有在请求、响应或服务器上添加 'timeout' 监听器，则在超时时，Http2Streams 会被销毁。如果为请求、响应或服务器的 'timeout' 事件分配了处理程序，则必须显式处理超时的套接字。

【If no 'timeout' listener is added to the request, the response, or the server, then Http2Streams are destroyed when they time out. If a handler is assigned to the request, the response, or the server's 'timeout' events, timed out sockets must be handled explicitly.】
