* **`200`** 及以上的状态码用于表示**成功**。这些状态码是最常用的
    * `200` 是默认状态代码，表示一切**正常**
    * `201` 表示**已创建**，通常在数据库中创建新记录后使用
    * `204` 是一种特殊的例子，表示**无内容**。该响应在没有为客户端返回内容时使用，因此，该响应不能包含响应体
* **`300`** 及以上的状态码用于**重定向**。具有这些状态码的响应不一定包含响应体，但 `304`**未修改**是个例外，该响应不得包含响应体
* **`400`** 及以上的状态码用于表示**客户端错误**。这些可能是第二常用的类型
    * `404`，用于**未找到**响应
    * 对于来自客户端的一般错误，可以只使用 `400`
