PHP案例实现“万能”的短网址还原功能
https://blog.ilingku.com/archives/4/
2026-04-07T19:57:00+08:00
常见的短网址都是通过 301 或 302 跳转的方式实现重定向到目标网站的，因此我们可以使用 PHP 的 curl_getinfo 来取得 header 中的重定向地址，也就是短网址对应的原始网址（嗯，原理就是这么简单……代码如下/***
* 万能短网址还原函数
* @param $shortUrl 短网址
* @return 原始网址 | 空（还原失败或非短网址）
*/function restoreUrl($shortUrl) {
$curl = curl_init();
curl_setopt($curl, CURLOPT_URL, $shortUrl);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:70.0) Gecko/20100101 Firefox/70.0');
curl_setopt($curl, CURLOPT_HEADER, true);
curl_setopt($curl, CURLOPT_NOBODY, false);
curl_setopt($curl, CURLOPT_TIMEOUT, 15);
curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 2);
curl_setopt($curl, CURLOPT_ENCODING, 'gzip');
$data = curl_exec($curl);
$curlInfo = curl_getinfo($curl);
curl_close($curl); if($curlInfo['http_code'] == 301 || $curlInfo['http_code'] == 302) { return $curlInfo['redirect_url'];
} return '';
}使用方法$shortUrl = 'https://url.cn/54VbB8h';
// 要还原的短网址
$orinalUrl = restoreUrl($shortUrl);
if($orinalUrl) {
echo "短网址 {$shortUrl} 的还原结果：{$orinalUrl}";
} else {
echo "短网址还原失败";
}

我用Curl比较多，也一直写类似的教程，今天发现大神出了一套非常好用的Curl封装的方法，特意转过来，以备使用！<?php

function teacher_curl($url, $paras = array()){
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); if (@$paras['Header']) {
$Header = $paras['Header'];

curl_setopt($ch, CURLOPT_HTTPHEADER, $Header); if (@$paras['ctime']) { // 连接超时
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $paras['ctime']);
} else {
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
