202Accepted

请求已被接受并进行处理，但处理尚未完成，请求最终可能会被处理，也可能不会被处理。这个状态码被设计用来将请求交由另外一个进程或者服务器来进行处理，或者是对请求进行批处理的情形。

The request has been accepted for processing, but the processing has not been completed. The request might or might not eventually be acted upon, as it might be disallowed when processing actually takes place.

There is no facility in HTTP for re-sending a status code from an asynchronous operation.

The 202 response is intentionally noncommittal. Its purpose is to allow a server to accept a request for some other process (perhaps a batch-oriented process that is only run once per day) without requiring that the user agent's connection to the server persist until the process is completed. The representation sent with this response ought to describe the request's current status and point to (or embed) a status monitor that can provide the user with an estimate of when the request will be fulfilled.
