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"111"

if __name__ == '__main__':
    main()
