如何取消 REST api 请求? [英] How to Cancel a REST api request?

问题描述

我使用基于 REST API 的系统，其中有些请求需要很长时间才能完成.我想给用户一个取消请求的选项.

I use REST API based system, in which there are some requests that take long time to complete. I want to give user an option to cancel the request.

推荐答案

一、支持

POST /requests

将返回对请求状态的引用

which will return a reference to the status of the request

{
    "id": 1234,
    "self"": "/requests/1234"
    "status": "Running"
}

然后添加对

PUT /requests/1234
{
    "status": "Canceled:"
}

如果请求尚未完成，这将允许客户端取消请求.如果请求是创建某种其他类型的资源，则不使用 POST/requests，而是执行 POST/myResource，但仍返回带有指向/requests 的指针的状态对象在回复中.

That will let clients cancel a request if it hasn't finished yet. If the request is to create some other kind of resource, then instead of POST /requests, do POST /myResource, but still return the status object with the pointer to /requests in the response.

然后客户端可以轮询 /requests 以查看请求何时完成.

Clients can then poll /requests to see when the request is complete.
