HTTP状态码检查工具
检查任意URL返回的HTTP状态码。检测200、301、404、500等。
如何使用本工具
- 1
Paste a full URL (for example https://example.com/page) into the input box.
- 2
Click Analyze to have our server fetch the URL on your behalf.
- 3
Read the large status code, its status text, and the Final URL after any redirects.

Change the URL and run again to compare endpoints or recheck after a fix.
什么是HTTP状态码检查工具？
HTTP状态码告诉你一个请求是成功、重定向还是失败了。最重要的几个类别：2xx（成功）、3xx（重定向）、4xx（客户端错误：404 Not Found、403 Forbidden）、5xx（服务器错误：500 Internal Server Error、503 Service Unavailable）。监控状态码可以发现失效的页面、配置错误的重定向以及服务器宕机。
常见使用场景
Confirm a page returns 200 OK after deploying a change or fixing a broken link.
Verify that an old URL ends at the right destination after setting up redirects for a site migration.
Diagnose why a link is failing by seeing whether it returns 404, 403, 401, or a 5xx error.
Spot-check that a server is reachable over HTTPS rather than only plain HTTP.
Test whether a third-party API endpoint or webhook URL responds before wiring it into your code.
Check competitor or partner URLs for outages or moved pages without installing any software.
