[英]How to redirect the page once the site is down in joomla
一旦我的 joomla 站点关闭,我如何重定向到另一个站点。
例如。
**http://localhost:8081/site** (it is orginal site)
如果它显示“页面无法显示”,它应该自动重定向到另一个站点
**http://localhost:8081/site1** (secondary site)
我试过了
<?php
header("http://localhost:8081/site/"); /*LIVE VERSION*/
function Redirect($http://localhost:8081/site/, $permanent = false)
{
if (headers_sent() === false)
{
header('Location: ' . $http://localhost:8081/site/, true, ($permanent === true) ? 301 : 302);
}
exit();
}
Redirect('http:http://localhost:8081/site1/', false);
die();
?>
但这对我不起作用。
您可以使用这样的函数:
$response = http_response_code();
movepage($response);
function movePage($num){
static $http = array (
100 => "HTTP/1.1 100 Continue",
101 => "HTTP/1.1 101 Switching Protocols",
200 => "HTTP/1.1 200 OK",
201 => "HTTP/1.1 201 Created",
202 => "HTTP/1.1 202 Accepted",
203 => "HTTP/1.1 203 Non-Authoritative Information",
204 => "HTTP/1.1 204 No Content",
205 => "HTTP/1.1 205 Reset Content",
206 => "HTTP/1.1 206 Partial Content",
300 => "HTTP/1.1 300 Multiple Choices",
301 => "HTTP/1.1 301 Moved Permanently",
302 => "HTTP/1.1 302 Found",
303 => "HTTP/1.1 303 See Other",
304 => "HTTP/1.1 304 Not Modified",
305 => "HTTP/1.1 305 Use Proxy",
307 => "HTTP/1.1 307 Temporary Redirect",
400 => "HTTP/1.1 400 Bad Request",
401 => "HTTP/1.1 401 Unauthorized",
402 => "HTTP/1.1 402 Payment Required",
403 => "HTTP/1.1 403 Forbidden",
404 => "HTTP/1.1 404 Not Found",
405 => "HTTP/1.1 405 Method Not Allowed",
406 => "HTTP/1.1 406 Not Acceptable",
407 => "HTTP/1.1 407 Proxy Authentication Required",
408 => "HTTP/1.1 408 Request Time-out",
409 => "HTTP/1.1 409 Conflict",
410 => "HTTP/1.1 410 Gone",
411 => "HTTP/1.1 411 Length Required",
412 => "HTTP/1.1 412 Precondition Failed",
413 => "HTTP/1.1 413 Request Entity Too Large",
414 => "HTTP/1.1 414 Request-URI Too Large",
415 => "HTTP/1.1 415 Unsupported Media Type",
416 => "HTTP/1.1 416 Requested range not satisfiable",
417 => "HTTP/1.1 417 Expectation Failed",
500 => "HTTP/1.1 500 Internal Server Error",
501 => "HTTP/1.1 501 Not Implemented",
502 => "HTTP/1.1 502 Bad Gateway",
503 => "HTTP/1.1 503 Service Unavailable",
504 => "HTTP/1.1 504 Gateway Time-out"
);
}
}
在最后一个函数中,根据需要使用 IF 将基重定向到。
