| 请求方法   | 目　标   | 说　　明 | HTTP状态码                                                |
| ------ | ----- | ---- | ------------------------------------------------------ |

| GET    | 资源集合的 | URL  | 获取资源的集合（如果服务器实现了分页，就是一页中的资源） 200                       |
| POST   | 资源集合的 | URL  | 创建新资源，并将其加入目标集合。服务器为新资源指派 URL，并在响应的 Location 首部中返回 201 |
| PUT    | 单个资源的 | URL  | 修改一个现有资源。如果客户端能为资源指派 URL，还可用来创建新资源 200                 |
| DELETE | 单个资源的 | URL  | 删除一个资源 200                                             |
