HTTP request methods

 

HTTP defines a set of request methods to indicate the desired action to be performed for a given resource. Although they can also be nouns, these request methods are sometimes referred to as HTTP verbs. Each of them implements a different semantic, but some common features are shared by a group of them: e.g. a request method can be safe, idempotent, or cacheable.

GET

The GET method requests a representation of the specified resource. Requests using GET should only retrieve data.

HEAD

The HEAD method asks for a response identical to that of a GET request, but without the response body.

POST

The POST method is used to submit an entity to the specified resource, often causing a change in state or side effects on the server.

PUT

The PUT method replaces all current representations of the target resource with the request payload.

DELETE

The DELETE method deletes the specified resource.

CONNECT

The CONNECT method establishes a tunnel to the server identified by the target resource.

OPTIONS

The OPTIONS method is used to describe the communication options for the target resource.

TRACE

The TRACE method performs a message loop-back test along the path to the target resource.

PATCH

The PATCH method is used to apply partial modifications to a resource.

HTTP 请求方法

规范

 

 

HTTP 定义了一组请求方法, 以表明要对给定资源执行的操作。指示针对给定资源要执行的期望动作. 虽然他们也可以是名词, 但这些请求方法有时被称为HTTP动词. 每一个请求方法都实现了不同的语义, 但一些共同的特征由一组共享：: 例如一个请求方法可以是 safe, idempotent, 或 cacheable (en-US).

GET

GET方法请求一个指定资源的表示形式. 使用GET的请求应该只被用于获取数据.

HEAD

HEAD方法请求一个与GET请求的响应相同的响应，但没有响应体.

POST

POST方法用于将实体提交到指定的资源，通常导致在服务器上的状态变化或副作用. 

PUT

PUT方法用请求有效载荷替换目标资源的所有当前表示。

DELETE

DELETE方法删除指定的资源。

CONNECT

CONNECT方法建立一个到由目标资源标识的服务器的隧道。

OPTIONS

OPTIONS方法用于描述目标资源的通信选项。

TRACE

TRACE方法沿着到目标资源的路径执行一个消息环回测试。

PATCH

PATCH方法用于对资源应用部分修改。
