.htaccess中/ PHP - 重新写，而重新定向到一个不同的URL网址 [英] HTACCESS / PHP - Re-write URL while re-directing to a different URL

问题描述

我建立一个网站，转诊方案，其中的引荐URL将会像 http://example.com/123456

I am creating a website with a referral scheme, where the referral URL will be something like http://example.com/123456

我想为只显示网址 http://example.com/ ，但仍然捕捉到 123456 并给予重点推荐。

I would like to display the URL as simply http://example.com/ but still capture the 123456 and give the referral point.

难道是可以用的.htaccess的mod_rewrite做到这一点？像

Would it be possible to do this with .htaccess mod_rewrite? something like

RewriteRule ^([0-9]+) ?ref=$1 [L]

将努力转发URL，但有没有办法在这里重定向和显示 http://example.com/ 在地址栏中，没有引用code吗？

would work to forward the URL, but is there a way to redirect here and display http://example.com/ in the address bar, without the referrer code?

这显然是可能的PHP头，但我倒是preFER不使用这个，如果在所有可能的。

It would obviously be possible with PHP Headers but I'd prefer not to use this if at all possible.

推荐答案

这是不可能的，只有RewriteModule一个简单的方法，因为HTTP的是一个无状态的协议。如果删除推荐ID和重定向用户，那么你就不会知道ID再上第二个请求。

This is not possible in a simple way with RewriteModule only, because of HTTP being a stateless protocol. If you remove the referral ID and redirect the user, then you won't know the ID anymore on the second request.

所以，你必须保存ID在Cookie或会话使用PHP和重定向与事后Location头的用户。

So you have to save the ID in a cookie or session with PHP, and redirect the user with the Location header afterwards.

的htaccess

RewriteRule ^([0-9]+) index.php?ref=$1 [L]

的index.php

index.php

if (isset($_GET["ref"])) {
  setcookie("refid", $_GET["ref"]);
  header("Location: http://example.com/");
  exit;
}
if (isset($_COOKIE["refid"])) {
  echo "You came from ref id: $_COOKIE[refid]";
} else {
  echo "You came without a ref id.";
}
