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
import base64
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_())
