我在python中得到一个奇怪的错误。当我尝试使用zip模块提取受密码保护的文件时，当尝试将“oy”设置为密码时出现异常。其他一切似乎都起作用了。ZipFile模块中的错误？import zipfile
zip = zipfile.ZipFile("file.zip", "r")
zip.setpassword("oy".encode('utf-8'))
zip.extractall() #Above password "oy" generates the error here
zip.close()
这是我得到的例外：Traceback (most recent call last):
File "unzip.py", line 4, in

max(n - len_readbuffer, self.MIN_READ_SIZE)
zlib.error: Error -3 while decompressing: invalid block type
如果使用UTF-16作为编码，则会出现以下错误：zlib.error: Error -3 while decompressing: invalid distance too far back
编辑
我现在已经在一台虚拟Linux机器上进行了以下测试：Python版本：2.6.5
我用zip -e file.zip
hello.txt创建了一个受密码保护的zip文件
现在看来问题出在别的地方了。现在我可以提取zip文件，即使密码是错误的！try:
zip.setpassword("ks") # "ks" is wrong password but it still extracts the zip
zip.extractall()
except RuntimeException:
print "wrong!"
有时我可以用不正确的密码提取zip文件。然后提取文件(在zip文件中)，但当我试图打开它时，信息似乎已损坏/解密。
