PHP sniffing the real flv file address of the youku video!

This is just to capture the contents of the friend network !!!

But it's pretty easy to use!

Check the code:

The code is as follows:

Copy code

<? Php $ Videourl = 'http: // v.youku.com/v_show/id_xmja5mjq0otq0.html '; Function get_content ($ url, $ data ){ If (is_array ($ data )){ $ Data = http_build_query ($ data ,'','&');  } $ Ch = curl_init (); Curl_setopt ($ ch, CURLOPT_RETURNTRANSFER, true ); Curl_setopt ($ ch, CURLOPT_POST, 1 ); Curl_setopt ($ ch, CURLOPT_HEADER, 0 ); Curl_setopt ($ ch, CURLOPT_URL, $ url ); Curl_setopt ($ ch, CURLOPT_POSTFIELDS, $ data ); $ Result = curl_exec ($ ch ); Return $ result; } $ Str = get_content ('http: // developer.pengyou.com/json.php? Mod = usershare & act = geturlinfo ', array ('URL' => $ videourl )); $ Str = json_decode ($ str ); Var_dump ($ str ); ?>

This test only shows that the swf file is not the flv file we want. Later, we improved it by referring to the method of a webmaster.

Core code:

The code is as follows:

Copy code

<? Php Function fetch_youku_flv ($ url ){ Preg_match ("# id _(.*?). Html # ", $ url, $ out ); $ Id = $ out [1]; $ Content = get_curl_contents ('http: // v.youku.com/player/getPlayList/VideoIDS/'.$id ); $ Data = json_decode ($ content ); Foreach ($ data-> data [0]-> streamfileids AS $ k => $ v ){ $ Sid = getSid (); $ Fileid = getfileid ($ v, $ data-> data [0]-> seed ); $ One = ($ data-> data [0]-> segs-> $ k ); If ($ k = 'flv' | $ k = 'MP4') return "response }? K = {$ one [0]-> k }"; Continue;     } }  Function get_curl_contents ($ url, $ second = 5 ){ If (! Function_exists ('curl _ init ') die ('php. ini has not enabled php_curl.dll '); $ C = curl_init (); Curl_setopt ($ c, CURLOPT_URL, $ url ); $ UserAgent = $ _ SERVER ['http _ USER_AGENT ']; Curl_setopt ($ c, CURLOPT_USERAGENT, $ UserAgent ); Curl_setopt ($ c, CURLOPT_HEADER, 0 ); Curl_setopt ($ c, CURLOPT_TIMEOUT, $ second ); Curl_setopt ($ c, CURLOPT_RETURNTRANSFER, true ); $ Cnt = curl_exec ($ c ); $ Cnt = mb_check_encoding ($ cnt, 'utf-8 ')? Iconv ('gbk', 'utf-8 // IGNORE ', $ cnt): $ cnt; // character encoding conversion Curl_close ($ c ); Return $ cnt; } Function getSid (){ $ Sid = time (). (rand (10000) + ); Return $ sid; } Function getkey ($ key1, $ key2 ){ $ A = hexdec ($ key1 ); $ B = $ a ^ 0xA55AA5A5; $ B = dechex ($ B ); Return $ key2. $ B; } Function getfileid ($ fileId, $ seed ){ $ Mixed = getMixString ($ seed ); $ Ids = explode ("*", $ fileId ); Unset ($ ids [count ($ ids)-1]); $ RealId = ""; For ($ I = 0; $ I <count ($ ids); ++ $ I ){ $ Idx = $ ids [$ I]; $ RealId. = substr ($ mixed, $ idx, 1 );     } Return $ realId; } Function getMixString ($ seed ){ $ Mixed = ""; $ Source = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ/:. _-1234567890 "; $ Len = strlen ($ source ); For ($ I = 0; $ I <$ len; ++ $ I ){ $ Seed = ($ seed * 211 + 30031) % 65536; $ Index = ($ seed/65536 * strlen ($ source )); $ C = substr ($ source, $ index, 1 ); $ Mixed. = $ c; $ Source = str_replace ($ c, "", $ source );     } Return $ mixed; }
