Zip 文件的 Python 问题

Question

免责声明:编码新手

C:\Python27\python.exe C:/Users/Evolution/PycharmProjects/MCMODVERSION/stuff/main.py
<open file 'C:\\Users\\Evolution\\Desktop\\mods\\AT_StalkerCreepers_1.6.4.jar', mode 'r' at 0x026F6A18>
Traceback (most recent call last):

<zipfile.ZipFile object at 0x02736EB0>

    o = t.getdirList()
True
  File "C:/Users/Evolution/PycharmProjects/MCMODVERSION/stuff/main.py", line 36, in getdirList
    self.getModinfo(os.path.join(p, o[n]), 'name')
  File "C:/Users/Evolution/PycharmProjects/MCMODVERSION/stuff/main.py", line 46, in getModinfo
    y = zipfile.ZipFile(x)
  File "C:\Python27\lib\zipfile.py", line 766, in __init__
    self._RealGetContents()
  File "C:\Python27\lib\zipfile.py", line 832, in _RealGetContents
    raise BadZipfile("Truncated central directory")
zipfile.BadZipfile: Truncated central directory

Process finished with exit code 1

正在执行的代码:

def getdirList(self):
    p = 'C:\Users\Evolution\Desktop\mods'
    o = [f for f in listdir(p) if isfile(join(p, f))]
    for mod in range(len(o)):
        print o[mod]
        self.getModinfo(os.path.join(p, o[mod]), 'name')


def getModinfo(self,mod,type):
    """ Types:
    modid, name, description, version, mcversion, url
    updateurl, authors, credits, dependencies """
    x = file(mod)
    print x
    print zipfile.is_zipfile(x)
    y = zipfile.ZipFile(x)
    print y

修正代码:

def getdirList(self):
    p = r'C:\Users\Evolution\Desktop\mods'
    o = [f for f in listdir(p) if isfile(join(p, f))]
    for mod in range(len(o)):
        print o[mod]
        self.getModinfo(os.path.join(p, o[mod]), 'name')

def getModinfo(self,mod,type):
    """ Types: modid, name, description, version, mcversion, 
    url, updateurl, authors, credits, dependencies """
    try:
        x = open(mod, 'rb')
        y = zipfile.ZipFile(x)
        z = y.read(self.minfo)
        #print z
        #zz = self.parseIt(z, '%s": ' % type, ',')
        #print zz
    except KeyError:
        print "ERROR: %s has no %s file!" % (x, self.minfo)
        print "%s" % "-" * 50
    x.close()

现在我运行检查，如您所见，该 zip 文件实际上是一个 zip 文件。超过一半的文件会抛出此异常。 .jar 和 .zip

是的，我已经手动打开了它们，它们没有损坏或被锁定或其他任何东西。有什么我可以做的或者我可以用来在 python 中操作 achrives 的另一个库吗？

谢谢。

Zip 文件是二进制文件。要正确处理二进制文件，您应该使用二进制模式打开文件。

替换以下行:

x = file(mod)

与:

x = file(mod, 'rb')

顺便说一句，在目录路径中转义 \，或者使用原始字符串文字。 (这不是问题的直接原因，但总有一天转义序列会麻烦你)

'C:\\Users\\Evolution\\Desktop\\mods' # escape

或

r'C:\Users\Evolution\Desktop\mods'    # raw string literal (`r` prefix)
