php - 检索 wordpress 页面的原始 url

Question

我知道，wordpress 会将紧密匹配的 url 重定向到其原始 url。但是，我需要在代码执行的一开始就知道实际的 url。是否可以？

1）如果有任何方法将 url 作为参数并返回其原始 wordpress url ，那会很好，但不确定它是否存在。有没有类似的东西？

2) 请问这个测试和重定向在代码中的哪个位置？

3）有没有什么钩子可以用来添加插件来控制这种情况？

提前致谢。

例子：

假设，我在这个网址上有一个帖子：“http://mydomain.com/example-post-page”

现在，如果我尝试通过“http://mydomain.com/example-post-page/”访问它，它会将您重定向到原始的第一个 url。对于 url 中的其他几个小更改也是如此，所有这些都会将您重定向到实际的永久链接 url。

我的目标是控制这种重定向。这就是为什么，当我在 "http://mydomain.com/example-post-page/" 上时，我想知道（我在根 index.php 上的代码）这是原始永久链接还是其他东西，在它重定向之前。

如果您尝试在 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 $_SERVER[ ] 看看这是否有你要找的东西。（提示：要在 php 中查看整个变量，请使用print_r($_SERVER);）

我在我的 wordpress 网站上执行了命令并返回：

$_SERVER['PARAMATER'] 可以从脚本中的任何位置访问这些参数中的任何一个。我希望这可以帮到你！

你是说the_permalink吗？http://codex.wordpress.org/Function_Reference/the_permalink

Answer 3

好的，最后我通过以下方式完成了它，对我来说似乎没问题：

1）收到大约网址。2) 使用这个近似 url 发出 cURL 请求。3）获取响应网址。4）返回响应网址。

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;
}}
