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。
