python更新zip文件中文件

#更新zip文件中某一个文件
import os
import shutil
import tempfile
import zipfile
from rat_tool.pack import *
toolpath= os.getcwd()+"/tool"
smalipath=os.path.join( toolpath,"smali.jar")
 
def updateZip(zipname, filename, data):
 
    tmpfd, tmpname = tempfile.mkstemp(dir=os.path.dirname(zipname))
 
    os.close(tmpfd)
 
    with zipfile.ZipFile(zipname, 'r') as zin:
 
        with zipfile.ZipFile(tmpname, 'w') as zout:
 
            zout.comment = zin.comment 
 
            for item in zin.infolist():
 
                if item.filename != filename:
 
                    zout.writestr(item, zin.read(item.filename))
 
    os.remove(zipname)
 
    os.rename(tmpname, zipname)
 
    with zipfile.ZipFile(zipname, mode='a', compression=zipfile.ZIP_DEFLATED) as zf:
 
        zf.writestr(filename, data)

使用：

#----更新apk文件中的classes3.dex文件------------------------------------------------------------------
def main():
    #将修改后的smali文件重新打包成dex,替换原来包中dex
    indir=r"D:\pa\apk\haoyishen\smali_classes3"
    outfile=r"D:\pa\apk\classes3.dex"
    #smali(indir, outfile)
    tempzip = r"D:\pa\apk\haoyishenbd.apk"
 
    buff=open(outfile,"rb").read()
    #updateZip(tempzip, "classes3.dex", buff)    
 
    signapk(tempzip, tempzip)
 
    print""
 
if __name__ == '__main__':
    main()
