使用隐式标头(不显式调用 response.writeHead())时,此属性控制在标头刷新时将发送到客户端的状态码。

response.statusCode = 404;


When using implicit headers (not calling response.writeHead() explicitly), this property controls the status code that will be sent to the client when the headers get flushed.

response.statusCode = 404;

After response header was sent to the client, this property indicates the status code which was sent out.
