RESTful Services 幾項重點

1. HTTP Method 對應Server處理方式

HTTP Method	Data operate	Description
POST	Create	Create a resource without id.
GET	Read	Get a resource.
PUT	Update	Update a resource or create a resource with id if not existed.
DELETE	Delete	Delete a resource

2. Server Response Content Type

    JSON or XML or Text

3. 透過 HTTP Authorization 限制使用者存取資源的權限，也可用其它方式(ip、cookie)

4. response status code、error code 直接參考 http status code

5. REST 中的資源 一般是名詞 (podcasts, customers, user, accounts 等) 而不是動詞 (getPodcast, deleteUser 等)
