Question

我正在使用下面的代码提取文件，如下所示，但我看到正在创建其他文件夹，有人可以帮助我为什么要创建额外的文件夹。

我的文件是abc.zip，其中包含文件sql.db，所以理想情况下我需要文件夹文件为abc / sql.db但是当我使用下面的代码提取时我得到文件夹为acb / abc / sql.db，为什么是我正在创建这个额外的文件夹

def unzip_artifact( local_directory, file_path ):
    fileName, ext = os.path.splitext( file_path )
    if ext == ".zip":
        print 'unzipping file ' + basename(fileName) + ext
        try:
            with zipfile.ZipFile(file_path) as zf:
                for member in zf.infolist():
                        # Path traversal defense copied from
                        # http://hg.python.org/cpython/file/tip/Lib/http/server.py#l789
                        words = member.filename.split('/')
                        path = local_directory
                        for word in words[:-1]:
                            drive, word = os.path.splitdrive(word)
                            head, word = os.path.split(word)
                            if word in (os.curdir, os.pardir, ''): continue
                            path = os.path.join(path, word)             
                        zf.extract(member, path)

        except zipfile.error, e:
            print "Bad zipfile: %s" % (e)
        return

通常解压缩文件会为您创建目录。因此，如果.zip文件中包含abc目录，那么您构建的路径就会受到影响。尝试：

def unzip_artifact( local_directory, file_path ):
    fileName, ext = os.path.splitext( file_path )
    if ext == ".zip":
        print 'unzipping file ' + basename(fileName) + ext
        try:
            with zipfile.ZipFile(file_path) as zf:
                for member in zf.infolist():
                        # Path traversal defense copied from
                        # http://hg.python.org/cpython/file/tip/Lib/http/server.py#l789
                        zf.extract(member, local_directory)
        except zipfile.error, e:
            print "Bad zipfile: %s" % (e)
        return

或者更好，只需使用extractall：

def unzip_artifact( local_directory, file_path ):
    fileName, ext = os.path.splitext( file_path )
    if ext == ".zip":
        print 'unzipping file ' + basename(fileName) + ext
        try:
            zipfile.ZipFile(file_path).extractall(local_directory)
        except zipfile.error, e:
            print "Bad zipfile: %s" % (e)
        return
