python将下载地址转换成迅雷和qq旋风的下载地址

迅雷和qq旋风下载，有加速和离线功能，很方面，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写了一个客户端

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

from PyQt4 import QtGui,QtCore
import os
import sys

class 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:‘+url
    if CheckUrl(url):
        main.setThunder(Url2Thunder(url))
        main.setQQDL(Url2QQdl(url))
    else:
        main.setError(‘Invalid link,Please try again‘)

#判断url是否有效
def CheckUrl(url):
    if re.match(‘(http|https|ftp|ed2k)://‘, url):
        return True
    else:
        return False

#转化成迅雷下载地址
def Url2Thunder(url):
    url=‘AA‘+url+‘ZZ‘
    url = base64.b64encode(url)
    url = ‘thunder://‘ + url
    print ‘thunder:‘+url
    return url

#转换成qq旋风下载地址
def Url2QQdl(url):
    url = base64.b64encode(url)
    url = ‘qqdl://‘ + url
    print ‘QQDL:‘+url
    return url

if __name__==‘__main__‘:
    app=QtGui.QApplication(sys.argv)
    main=Window()
    main.show()
    sys.exit(app.exec_())
