检索wordpress页面的原始网址

Question

我知道，wordpress将紧密匹配的网址重定向到其原始网址。但是，我需要知道代码执行开始时的实际url。可能吗？

1）如果有任何方法需要一个url作为参数，并返回它的原始wordpress url ，这将是伟大的，但不确定，不管它是否存在。有没有这样的事情？

2）代码中的哪个实际执行此测试和重定向？

3）是否有任何钩子可以用来添加插件来控制这种情况？

在此先感谢。

例子：

想，我对这个URL一个帖子： “http://mydomain.com/example-post-page”

现在，如果我尝试通过“HTTP访问它： //mydomain.com/example-post-page/“，它会将您重定向到原始的第一个网址。对于url的其他几个小变化也是如此，所有这些都会将你重定向到实际的permalink url。

我的目标是控制这个重定向。这就是为什么当我在“http://mydomain.com/example-post-page/”时，我喜欢知道（我在root index.php中的代码）是否这是origianl永久链接或是其他内容，在重定向之前。

好了，最后我得到了它以下列方式进行，对我来说似乎确定：

1）收到约网址。 2）使用这个大约的url进行cURL请求。 3）获取响应网址。 4）返回响应url。

代码如下：

function get_actual_url($approx_url){ 
$curlObj = curl_init(); 
curl_setopt($curlObj, CURLOPT_URL, $approx_url); 
curl_setopt($curlObj, CURLOPT_RETURNTRANSFER, true); 
curl_setopt($curlObj, CURLOPT_FOLLOWLOCATION, true); 
curl_setopt($curlObj, CURLOPT_ENCODING , "gzip"); 
curl_setopt($curlObj, CURLOPT_TIMEOUT,180); 

$content = curl_exec($curlObj); 

$info = curl_getinfo($curlObj); 
curl_close($curlObj); 

if(!empty($info) && !empty($info["url"])){ 
    return $info["url"]; 
} 
else { 
    return $approx_url; 
}}

如果您试图在PHP中执行此操作，您可以询问服务器请求的URL是什么。尝试访问$ _SERVER []并查看它是否具有您要查找的内容。 （普罗蒂普：看到PHP整个变量，使用print_r($_SERVER);）

我执行我的WordPress站点的命令回来：

任何这些PARAMATERS的人们可以通过$ _ SERVER [访问'PARAMATER']从你脚本的任何地方。 我希望这有帮助！

您的意思是the_permalink？ http://codex.wordpress.org/Function_Reference/the_permalink
