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。
