StackOverFlow上的關於Rest put 和post請求的討論

--來自stackOverFlow上的關於，post和put請求區別的一場討論

Use POST to create, and PUT to update. That's how Rails is doing it, anyway.
PUT /items/1 #=> update
POST /items #=> create

PUT：
PUT /resources/<existingResourceId> HTTP/1.1
PUT /resources/<newResourceId> HTTP/1.1
在原來resourceID下進行Put請求，就是對資源的更新
在新的資源ID下進行PUT請求，則是建立新的資源
POST
Create a new resource under the /resources URI, or collection. Usually the identifier is returned by the server.
--POST /resources HTTP/1.1
--POST在原來的資源ID下新增新的物件

網友的評論：

• PUT is not for update, it is for replace, note that to create you are replacing nothing with something. POST is absolutely not for update in any shape of form.

--POST is used to create.
--PUT is used to create or update.

• Both PUT and POST can be used for creating.
