这个工具能做什么
每个 HTTP 响应都会带一个三位数状态码，用来告诉客户端发生了什么：2xx 表示成功，3xx 表示重定向，4xx 表示客户端问题，5xx 表示服务器故障。这个工具内置常见的 IANA 注册状态码和通俗说明，让你不用离开编辑器就能确认某个状态码的含义，或找到更适合接口返回的状态码。
使用方法
- 输入状态码、名称，或像“rate limit”这样的关键词。
- 可选地把结果缩小到某一类状态码（1xx-5xx）。
- 阅读匹配状态码的简短解释。
隐私说明
本工具完全在你的浏览器中运行。输入的内容不会被上传、保存或分享，关闭标签页即随之消失。
常见问题
- 这份列表来自哪里？
- 工具内置了一份常见 IANA 注册状态码表，覆盖网页 API 和浏览器交互中最常见的状态码，不会请求服务器。
- 401 和 403 有什么区别？
- 401 Unauthorized 表示请求需要有效的认证凭据；403 Forbidden 表示服务器知道你是谁，但仍然拒绝授权这次操作。
- 为什么会有 418？
- "I'm a Teapot" 来自 1998 年愚人节 RFC。它很少被严肃使用，不过有些 API 会把它当作彩蛋。
