Question

这是Youtube视频的实际网址，此时如果您复制到Chrome浏览器，则可能会观看该视频。但是当我尝试创建请求时，我得到UriFormatException。我做错了什么？

HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url);

HTTP：/ R6 --- sn-x5jjxnn-ogul.googlevideo.com/videoplayback?ratebypass=yes&ms=au&fexp=924615,912522,932260,910207,936330,916611,936117,936910 ，936913＆安培;源= YouTube和安培; sver = 3及MV = M＆安培; ITAG = 43＆安培;键= YT5＆安培; IP = 119.72.195.38＆安培; UPN = cBXbXj9uR-K＆安培; ipbits = 0和ID = e9b0fb53c92a23c0＆安培;到期= 1391346085＆安培; sparams =号，IP，ipbits，ITAG，ratebypass，来源，UPN，到期＆安培; MT = 1391322689＆安培; fallback_host = tc.v17.cache3.googlevideo.com＆安培;签名= EC0116EE4A09D80D38ACB1302F6776320D55A20C.518C15D3446E72D5E764D93AFBA0804B9257914F

Answer 1

罪犯是这个家伙“http：/ r”。快速破解它是下面的代码

 if (url.StartsWith("http:/r"))
            url = url.Replace("http:/r", "http://r");

可能会稍后修改一般

Answer 2

导航到此网址时检查您的浏览器，因为它被重定向到http://r2...。

复制重定向的网址并改为使用它：

http://r2---sn-aigeznl6.googlevideo.com/videoplayback?ratebypass=yes&fexp=924615,912522,932260,910207,936330,916611,936117,936910,936913&source=youtube&sver=3&itag=43&key=yt5&ip=119.72.195.38&upn=cBXbXj9uR-k&ipbits=0&id=e9b0fb53c92a23c0&expire=1391346085&sparams=id,ip,ipbits,itag,ratebypass,source,upn,expire&fallback_host=tc.v17.cache3.googlevideo.com&signature=EC0116EE4A09D80D38ACB1302F6776320D55A20C.518C15D3446E72D5E764D93AFBA0804B9257914F&redirect_counter=1&cms_redirect=yes&ms=nxu&mt=1391323695&mv=m
