迅雷和qq旋风下载，有加速和离线功能，非常方面，我是在网上看到的原始地址和迅雷地址，qq旋风地址的转化原理。然后用python+pyqt写了一个client

原理：

迅雷: 迅雷下载地址="thunder://"+Base64编码("AA"+"真实地址"+"ZZ")

QQ旋风: qqdl="qqdl://"+Base64编码("真实地址")

import re
import base64
from PyQt4 import QtGui,QtCore
import os
import sysclass Window(QtGui.QWidget):def __init__(self):QtGui.QWidget.__init__(self)self.linklabel=QtGui.QLabel('link:',self)self.link=QtGui.QLineEdit(self) self.thunderlabel=QtGui.QLabel('Thunder:',self)self.thunder=QtGui.QLineEdit(self)self.qqdllabel=QtGui.QLabel('qqdl',self)self.qqdl=QtGui.QLineEdit(self)transbutton=QtGui.QPushButton('Transition',self)grid=QtGui.QGridLayout()grid.addWidget(self.linklabel)grid.addWidget(self.link)grid.addWidget(self.thunderlabel)grid.addWidget(self.thunder)grid.addWidget(self.qqdllabel)grid.addWidget(self.qqdl)grid.addWidget(transbutton)self.resize(500,200)self.setLayout(grid)self.setWindowTitle('Transition  by loster v0.1')self.connect(transbutton,QtCore.SIGNAL('clicked()'),Trans)def getUrl(self):return self.link.text()def setThunder(self,url):self.thunder.setText(url)def setQQDL(self,url):self.qqdl.setText(url)def setError(self,warning):QtGui.QMessageBox.warning( self, "Transition", warning, QtGui.QMessageBox.Yes )def Trans():#获得链接url=main.getUrl() print 'url:'+urlif CheckUrl(url):main.setThunder(Url2Thunder(url))main.setQQDL(Url2QQdl(url))else:main.setError('Invalid link,Please try again')#推断url是否有效
def CheckUrl(url):if re.match('(http|https|ftp|ed2k)://', url):return Trueelse:return False#转化成迅雷下载地址
def Url2Thunder(url):url='AA'+url+'ZZ'url = base64.b64encode(url)  url = 'thunder://' + urlprint 'thunder:'+urlreturn url#转换成qq旋风下载地址
def Url2QQdl(url):  url = base64.b64encode(url)  url = 'qqdl://' + urlprint 'QQDL:'+urlreturn urlif __name__=='__main__':app=QtGui.QApplication(sys.argv)main=Window()main.show()sys.exit(app.exec_())
