如何通过链接获取跳转后的url参数

本帖最后由 bing15 于 2014-09-12 14:27:23 编辑我有一个链接，

https://wx2.qq.com/cgi-bin/mmwebwx-bin/webwxcheckurl?uin=2447168038&sid=06HuH3sMX61oW3Ql&skey=%40crypt_bcc81ca8_5e4f10a91e02160feafddb694ba29185&deviceid=e333050774658970&opcode=2&requrl=https%3A%2F%2Fopen.weixin.qq.com%2Fconnect%2Foauth2%2Fauthorize%3Fappid%3Dwxdb2a2367e10c1ba6%26redirect_uri%3Dhttp%253A%252F%252Fm.lbtest.imixun.com%252Fweixin.php%26response_type%3Dcode%26scope%3Dsnsapi_base%26state%3D123%23wechat_redirect&scene=1&username=wxid_d50xcfkfwuiu12

如何获取到跳转后的url参数，
我这样写都不行

        $url = 'https://wx2.qq.com/cgi-bin/mmwebwx-bin/webwxcheckurl?uin=2447168038&sid=06HuH3sMX61oW3Ql&skey=%40crypt_bcc81ca8_5e4f10a91e02160feafddb694ba29185&deviceid=e333050774658970&opcode=2&requrl=https%3A%2F%2Fopen.weixin.qq.com%2Fconnect%2Foauth2%2Fauthorize%3Fappid%3Dwxdb2a2367e10c1ba6%26redirect_uri%3Dhttp%253A%252F%252Fm.lbtest.imixun.com%252Fweixin.php%26response_type%3Dcode%26scope%3Dsnsapi_base%26state%3D123%23wechat_redirect&scene=1&username=wxid_d50xcfkfwuiu12';
		$ch = curl_init();
		curl_setopt($ch, CURLOPT_URL, $url);
		curl_setopt($ch, CURLOPT_HEADER, true);
		curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
		curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
		$content = curl_exec($ch);
		echo $content;

------解决思路----------------------
你这个 url 能返回什么？
直接浏览器，返回为空页面
curl 自然也不会有返回

https 是需要证书的
如确认不需要证书，则需需要有 curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
但也只能得到头
HTTP/1.1 200 OK
Content-Type: text/html; charset=gbk
Cache-Control: no-cache, must-revalidate
Content-Length: 0

在谷歌浏览器中是可以打，IE确实不行
有一个问题，在我的app中去请求微信接口的时候，会报“请在微信客户端打开链接”
我本身就是通过微信进去的啊，怎么还提示这个,下面是代码：
$encodeUrl=urlencode('http://m.lbtest.imixun.com'); $url = 'https://open.weixin.qq.com/connect/oauth2/authorize?appid=wxdb2a2367e10c1ba6&redirect_uri='.$encodeUrl.'&response_type=code&scope=snsapi_base&state=123#wechat_redirect'; 		$ch = curl_init(); 		curl_setopt($ch, CURLOPT_URL, $url); 		curl_setopt($ch, CURLOPT_HEADER, true); 		curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); 		curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); 		curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0); 		$content = curl_exec($ch); 		echo $content;

得设置referer他是通过referer来检测的
------解决思路----------------------
这个url是哪个接口的?

How do you loop through all the values stored in a PHP session?Apr 26, 2025 am 12:06 AM

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.
