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

结束发送请求。 如果部分请求主体还未被发送,则会刷新它们到流中。 如果请求是分块的,则会发送终止字符 '0\r\n\r\n'

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

如果指定了 callback,则当请求流结束时会被调用。

Finishes sending the request. If any parts of the body are unsent, it will flush them to the stream. If the request is chunked, this will send the terminating '0\r\n\r\n'.

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

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