'checkContinue' 事件


每次收到 HTTP Expect: 100-continue 的请求时都会触发。 如果未监听此事件,服务器将自动响应 100 Continue

处理此事件时,如果客户端应继续发送请求主体,则调用 response.writeContinue(),如果客户端不应继续发送请求主体,则生成适当的 HTTP 响应(例如 400 Bad Request)。

请注意,在触发和处理此事件时,不会触发 'request' 事件。

Emitted each time a request with an HTTP Expect: 100-continue is received. If this event is not listened for, the server will automatically respond with a 100 Continue as appropriate.

Handling this event involves calling response.writeContinue() if the client should continue to send the request body, or generating an appropriate HTTP response (e.g. 400 Bad Request) if the client should not continue to send the request body.

Note that when this event is emitted and handled, the 'request' event will not be emitted.
