Python Falcon 简明教程

Python Falcon - Status Codes

默认情况下，HTTP 服务器对客户端请求的响应具有 200 OK 状态。Falcon 提供了自己的状态常量列表，以提高便利性和可读性。

例如，200 OK 状态代码表示为：

resp.status = falcon.HTTP_OK

这些预定义的 Falcon 常量避免了输入错误，并减少了准备响应时必须创建的字符串对象数量。然而，从 Falcon 3.0 版本开始，允许使用 int 代码。

resp.status = 200

对于 ASGI 应用程序，相同的状态代码适用。

Falcon 库中定义的部分状态代码如下：
