使用说明与常见问题How-to & FAQ

「网页跳转代码生成」是什么？What is the Redirect Code Generator tool?

如何使用「网页跳转代码生成」？How do I use the Redirect Code Generator?

在输入框填写要跳转到的完整网址，选择 301（永久）或 302（临时）和需要的语言，复制生成的代码放进你的页面或配置即可。前端跳转（JS、meta）无法返回真正的 301 状态码。Enter the full destination URL, choose 301 (permanent) or 302 (temporary) and a language, then copy the code into your page or config. Client-side redirects (JS, meta) cannot send a real 301 status.

301 和 302 怎么选？Should I use 301 or 302?

网址永久搬家（换域名、改版后旧链接）用 301，搜索引擎会把收录和权重转移到新地址；只是临时跳转（活动页、维护页）用 302。307/308 与 302/301 含义相同，但要求浏览器保持原来的请求方法（如 POST）。Use 301 when a URL has moved for good (new domain, old links after a redesign) so search engines transfer indexing to the new URL; use 302 for temporary moves. 307/308 mean the same as 302/301 but require the browser to keep the request method (e.g. POST).

PHP 跳转报 headers already sent 怎么办？What if PHP says "headers already sent"?

header() 必须在任何输出（包括 HTML、空格、BOM）之前调用。把跳转代码放到文件最开头，并确认文件保存为无 BOM 的 UTF-8。header() must run before any output, including HTML, whitespace or a BOM. Put the redirect at the very top of the file and save it as UTF-8 without BOM.
