PHP如何通过URL访问,获得新的URL 【调用百度地图】
我是想在手机微信上进行一段导航
当前导航的URL地址如果录入到IE地址栏中是能正常访问的:http://api.map.baidu.com/direction?origin=latlng:24.481428,118.124813|name:测试起点&destination=latlng:24.503361,118.139877|name:测试终点&mode=driving®ion=厦门&output=html

录入后,回车会发现地址变成了:
http://map.baidu.com/?l=&s=nav%26sn%3D1%24%24%24%2413149737.11%2C2794316.21%24%24%E6%B5%8B%E8%AF%95%E8%B5%B7%E7%82%B9%24%24%24%24%24%24%26en%3D1%24%24%24%2413151414.05%2C2796984.18%24%24%E6%B5%8B%E8%AF%95%E7%BB%88%E7%82%B9%24%24%24%24%24%24%26sc%3D194%26ec%3D194

想知道如果用PHP如何实现 根据原来的URL,请求后得到新的URL?谢谢。






------解决方案--------------------
原來的url是http://api.map.baidu.com/direction?origin=latlng:24.481428,118.124813
------解决方案--------------------
name:测试起点&destination=latlng:24.503361,118.139877
------解决方案--------------------
name:测试终点&mode=driving®ion=厦门&output=html

新的url是http://map.baidu.com/?l=&s=nav%26sn%3D1%24%24%24%2413149737.11%2C2794316.21%24%24%E6%B5%8B%E8%AF%95%E8%B5%B7%E7%82%B9%24%24%24%24%24%24%26en%3D1%24%24%24%2413151414.05%2C2796984.18%24%24%E6%B5%8B%E8%AF%95%E7%BB%88%E7%82%B9%24%24%24%24%24%24%26sc%3D194%26ec%3D194

用新的url就可以打開了,舊的不行,對嗎?

所以你想可以根據舊url獲取新url然後使用?
------解决方案--------------------
试试.

$url = 'http://api.map.baidu.com/direction?origin=latlng:24.481428,118.124813
------解决方案--------------------
name:测试起点&destination=latlng:24.503361,118.139877
------解决方案--------------------
name:测试终点&mode=driving®ion=厦门&output=html';
$newurl = getMapUrl($url);
echo $newurl;

function getMapUrl($url){
file_get_contents($url);
$result = $http_response_header;
if($result){
foreach($result as $val){
if(substr($val,0,10)=='Location: '){
return str_replace('Location: ','', $val);
}
}
}
return '';
}
