response.end([data][, encoding][, callback])


此方法向服务器发出信号,表明已发送所有响应头和主体,该服务器应该视为此消息已完成。 必须在每个响应上调用此 response.end() 方法。

如果指定了 data,则相当于调用 response.write(data, encoding) 之后再调用 response.end(callback)

如果指定了 callback,则当响应流完成时将调用它。

This method signals to the server that all of the response headers and body have been sent; that server should consider this message complete. The method, response.end(), MUST be called on each response.

If data is specified, it is equivalent to calling response.write(data, encoding) followed by response.end(callback).

If callback is specified, it will be called when the response stream is finished.
