在python中压缩二进制文件

Question

我试图在zip文件中包含一个二进制文件，下面是代码片段： 我首先将压缩内容解压缩到一个临时位置，再添加几个文件，然后将其压缩回一个新的归档文件中。在

import zipfile

def test(fileName, tempDir):
    # unzip the file contents,may contain binary files
    myZipFile=zipfile.ZipFile(fileName,'r')
    for name in myZipFile.namelist(): 
        toFile = tempDir + '/' + name
        fd = open(toFile, "w")
        fd.write(myZipFile.read(name))
        fd.close()
    myZipFile.close()
    # code which post processes few of the files goes here

    #zip it back
    newZip = zipfile.ZipFile(fileName, mode='w')
    try:
        fileList = os.listdir(tempDir)
        for name in fileList:
            name = tempDir + '/' + name
            newZip.write(name,os.path.basename(name))
        newZip.close()
    except Exception:
            print 'Exception occured while writing to PAR file: ' + fileName    

有些文件可能是二进制文件。压缩代码工作正常，但当我尝试使用linux的unzip或python的zip模块解压缩时，我得到了以下错误：

zipfile corrupt. (please check that you have transferred or created the zipfile in the appropriate BINARY mode and that you have compiled UnZip properly)

我使用的是python2.3

这里怎么了？在

嗯不确定是不是Python2.3中的bug。当前的工作环境不允许我升级到更高版本的python:-（：-（：-）

以下解决方法有效：

import zipfile

def test(fileName, tempDir):
    # unzip the file contents,may contain binary files
    myZipFile=zipfile.ZipFile(fileName,'r')
    for name in myZipFile.namelist(): 
        toFile = tempDir + '/' + name

        # check if the file is a binary file
        #if binary file, open it in "wb" mode
            fd = open(toFile, "wb")
        #else open in just "w" mode
            fd = open(toFile, "w")

        fd.write(myZipFile.read(name))
        fd.close()
    myZipFile.close()
    # code which post processes few of the files goes here

    #zip it back
    newZip = zipfile.ZipFile(fileName, mode='w')
    try:
        fileList = os.listdir(tempDir)
        for name in fileList:
            name = tempDir + '/' + name
            newZip.write(name,os.path.basename(name))
        newZip.close()
    except Exception:
            print 'Exception occured while writing to PAR file: ' + fileName

您可能需要升级，因为python2.3已经过时了。2.7.3是2.x版本中的最新版本，3.2.3是最新的python版本。在

见docs.python.org：

 |  extractall(self, path=None, members=None, pwd=None)
 |      Extract all members from the archive to the current working
 |      directory. `path' specifies a different directory to extract to.
 |      `members' is optional and must be a subset of the list returned
 |      by namelist().

看看Zip a folder and its content。在
