Server returned HTTP response code: 403 for URL怎么解决
Server returned HTTP response code: 403 for URL: http://f.youku.com/player/getFlvPath/sid/00_00/st/flv/fileid/03000201004ED6BF48F027006A8E437E675E32-B23A-7BF2-3B22-0332C714DFDB?K=8059f0d62a4e740f261c083f

网上找了很多方法,都不能搞定

下面是网上找到一个方法:
最近在做一个基于不同协议实现跨库资源检索的小程序，在基于OpenURL时，采用网络抓取的形式获取结果页，其中遇到这样的错误：
Server returned HTTP response code: 403 for URL: http://www……………………而可以使用浏览器正确访问
 
 因为服务器的安全设置不接受Java程序作为客户端访问

解决方案：设置User Agent

即在url.openConnection()后添加：

connection.setRequestProperty("User-Agent", "Mozilla/4.0 (compatible; MSIE 5.0; Windows NT; DigExt)");


但是我就是不行,换成了Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0)也不成,是不是和系统和IE版本有关。
