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。
转码的原因是 上面带中文的,我发现微信里,IPHONE导航页面打不开,是空白的。
但是如果通过URL请求后,得到的新URL,配置在微信里是可以正常打开百度地图的。
所以我想写一个函数来处理这个,求教高手,谢谢。
原?的url是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
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

urlencode?
