使用flash buidler 4制作一个迅雷快车旋风地址转换（附源代码）

 纪念独立博客开博一周年，并且纪念下一年前学习flex，特弄个小Demo,顺便使用下flash buidler 4。
开发需求：比如有时下载个东西，上面的地址是flashget地址，你用迅雷就无法下载，那么就要进行地址转换。
要想开发这个必须知道迅雷，快车及旋风的加密方式，经过参考网上很多的此类似工具转换得出以下：
【注：转载此文请注明转载地址或加上我的博客地址http://www.ajaxcn.net/archives/1013】
迅雷的加密的方式：
thunder://"+使用base64转换加密("AA"+下载地址+"ZZ")；
代码="thunder://"+Base64.encode("AA"+txtresult.text+"ZZ");
快车的加密的方式：
flashget://"+使用base64转换加密("[FLASHGET]"+下载地址+"[FLASHGET]")+"&111";//&后可随意
旋风加密的方式：
"qqdl://"+使用base64转换加密(下载地址)；
以上是加密，解密的话就是反向求出上面的下载地址
比如迅雷：先要去掉thunder:// 就是要截断去掉前10个字，然后通过base64转换解密再去掉
"AA"和"ZZ"字母,在flex中代码大致如下：
url=url.substr(10,url.length-10);
str=Base64.decode(url);
str=str.substr(2,str.length-4);
另外说明：上面 Base64.encode，Base64.decode,Base64在flex中并没有内置函数，需要引用一个as3base64.swc，
并且需要引用 import com.dynamicflash.util.Base64;具体使用不明白请参考：http://www.dynamicflash.com/goodies/base64
其它快车和旋风解密类似，具体看代码吧！
