问题描述
在 RESTful 风格的编程中，我们应该使用 HTTP 方法作为我们的构建块.尽管哪些方法与经典的 CRUD 方法相匹配，但我有点困惑.GET/Read 和 DELETE/Delete 已经很明显了.
In RESTful style programming, we should use HTTP methods as our building blocks. I'm a little confused though which methods match up to the classic CRUD methods. GET/Read and DELETE/Delete are obvious enough.
但是，PUT/POST 有什么区别呢?它们是否与创建和更新一一匹配?
However, what is the difference between PUT/POST? Do they match one to one with Create and Update?
推荐答案
Create = PUT with a new URI
POST to a base URI returning a newly created URI
Read = GET
Update = PUT with an existing URI
Delete = DELETE
PUT 可以映射到 Create 和 Update，具体取决于与 PUT 一起使用的 URI 的存在.
PUT can map to both Create and Update depending on the existence of the URI used with the PUT.
POST 映射到 Create.
POST maps to Create.
更正:POST 也可以映射到更新，尽管它通常用于创建.POST 也可以是部分更新，因此我们不需要建议的 PATCH 方法.
Correction: POST can also map to Update although it's typically used for Create. POST can also be a partial update so we don't need the proposed PATCH method.
