表示“即发即忘"的 HTTP 方法RESTful 服务中的操作 [英] HTTP method to represent "fire and forget" actions in RESTful service

问题描述

考虑到 REST，将 HTTP 方法映射到 CRUD 操作相对容易:POST 用于创建，GET 用于读取等.但是即发即弃"操作呢?哪种 HTTP 方法最能代表触发并忘记操作，例如触发批处理作业(其中没有响应发送回调用者)?

Thinking about REST, it's relatively easy to map HTTP methods to CRUD actions: POST for create, GET for read, etc. But what about "fire and forget" actions? What HTTP method would best represent a fire and forget action such as triggering a batch job (in which no response is sent back to the caller)?

POST 会浮现在脑海中，但我认为 GET 也是一种合适的方法，因为 99% 的时间您只为这些类型的操作提供一堆参数.你怎么认为?

POST would spring to mind, but I think GET is also an appropriate method because 99% of the time you only supply a bunch of parameters to these types of actions. What do you think?

外部状态

我认为您使用的参数数量与您使用的动词无关.关键问题是您是否正在更改外部可见状态?

External State

I think that the number of parameters you use has nothing to do with the verb you use. The key issue is are you changing externally visible state?

在您的示例中，如果批处理作业不影响任何对象的外部可见状态，那么您可以将其实现为批处理作业.但是，您可以将批处理作业建模为具有关联资源容器的资源.

In your example, if the batch job does not affect the externally visible state of any object then you could implement it as a batch job. However you could model your batch job as a resource with an associated resource container.

您可以使用 Post 来创建新的 BatchJob 资源，并允许用户执行 GET 以查看到目前为止的作业进度.您可以对资源容器执行 GET 以列出所有正在运行的批处理作业，可能调用 DELETE 来终止一个.

You could use a Post to create a new BatchJob resource and allow the user to do a GET to see the progress of the job so far. You could do a GET on the resource container to list all of the running batch jobs, possibly calling DELETE to kill one.
