RESTful api：post 与 put的区别

无论是post还是put，两者都可以创建和更新资源。

• 创建：post不需要指定被创建资源的id，而put需要指定
• 更新：两者都要指定被更新资源的id

POST:

> modify and update a resource
POST /questions/ HTTP/1.1

> create a resource:
POST /questions HTTP/1.1

> Note that the following is an error:
POST /questions/ HTTP/1.1


PUT:

> To overwrite an existing resource:
PUT /questions/ HTTP/1.1

> create a resource:
PUT /questions/ HTTP/1.1
