使用 PHP 进行 301 或 302 重定向 [英] 301 or 302 Redirection With PHP
问题描述
我正在考虑在网站启动阶段使用以下代码向用户显示一个停机维护页面，同时向我显示网站的其余部分.
I'm considering using the following code during a website launch phase to show users a down for maintenance page while showing me the rest of the site.
有没有办法向搜索引擎显示正确的 302 重定向状态，还是我应该寻找另一种基于 .htaccess 的方法?
Is there a way to show the correct 302 re-direction status to search engines or should I look for another .htaccess based approach?
$visitor = $_SERVER['REMOTE_ADDR'];
if (preg_match("/192.168.0.1/",$visitor)) {
header('Location: http://www.yoursite.com/thank-you.html');
} else {
header('Location: http://www.yoursite.com/home-page.html');
};
推荐答案
对于 302 Found，即临时重定向执行:
For a 302 Found, i.e. a temporary redirect do:
header('Location: http://www.example.com/home-page.html');
// OR: header('Location: http://www.example.com/home-page.html', true, 302);
exit;
如果您需要永久重定向，又名:301 Moved Permanently，请执行:
If you need a permanent redirect, aka: 301 Moved Permanently, do:
header('Location: http://www.example.com/home-page.html', true, 301);
exit;
有关更多信息，请查看 PHP 手册以了解 header 函数 Doc.另外，不要忘记在使用 header('Location: ');
For more info check the PHP manual for the header function Doc. Also, don't forget to call exit; when using header('Location: ');
但是，考虑到您正在进行临时维护(您不希望搜索引擎索引您的页面)，建议返回带有自定义消息的 503 Service Unavailable(即您不需要任何重定向):
But, considering you are doing a temporary maintenance (you don't want that search engines index your page) it's advised to return a 503 Service Unavailable with a custom message (i.e. you don't need any redirect):
<?php
header("HTTP/1.1 503 Service Unavailable");
header("Status: 503 Service Unavailable");
header("Retry-After: 3600");
?><!DOCTYPE html>
<html>
<head>
<title>Temporarily Unavailable</title>
<meta name="robots" content="none" />
</head>
<body>
Your message here.
</body>
</html>
