【问题描述】：

我想使用 Python 语言从给定的 FileShare 位置获取文件名列表（仅限）。这是我的代码 sn-p，但它没有运行列出任何文件。

    import os
    from os import walk
    SQLSR_USER= 'username'
    SQLSR_PASS= 'password'
    BACKUP_REPOSITORY_PATH= '\\fileshare\location'
    fileList = []
    backup_storage_available = os.path.isdir(BACKUP_REPOSITORY_PATH)
    if backup_storage_available:
            print("Backup storage already connected.")
    else:
        print("Connecting to backup storage.")

        mount_command = "net use /user:" + SQLSR_USER + " " + BACKUP_REPOSITORY_PATH + " " + SQLSR_PASS
        os.system(mount_command)
        backup_storage_available = os.path.isdir(BACKUP_REPOSITORY_PATH)    
        if backup_storage_available:
            print ("Connection success.")
        else:
            raise Exception("Failed to find storage directory.")

    for (dirpath, dirnames, filenames) in walk(backup_storage_available):
         fileList.extend(filenames)
         break

    if (len(fileList) > 1):
        print "\n\n *********************Required data files are present in the FileShare*********************"

    else:
        print "\n\n ********************* No files are present to start the Next Run *********************"

我仍然对列出的 NET USE 连接命令有问题

    mount_command = "net use /user:" + SQLSR_USER + " " + BACKUP_REPOSITORY_PATH + " " + SQLSR_PASS
    os.system(mount_command)
    backup_storage_available = os.path.isdir(BACKUP_REPOSITORY_PATH)

【问题讨论】：

try r'\\fileshare\location'，否则，错误信息是什么？
是的，它有效。感谢你的及时回复。但是，如何断开它，这意味着在我的代码中我已经提示“备份存储已连接”，所以我无法检查“NET USE”选项请建议使用断开脚本！
小提示：要格外小心，SQLSR_USER/PATH 和 BACKUP_REPO_PATH 不能像 web 服务或其他东西一样远程填写（或彻底检查它们）。那个 os.system 调用可能会给你带来一些麻烦
"backup_storage_available = os.path.isdir(BACKUP_REPOSITORY_PATH)" 该代码块返回 false，因为该远程路径未经过身份验证。

最后我使用 pywin32 模块解决了我的问题。下面是它的代码。

    def wnet_connect(host, username, password):
        unc = ''.join(['\\\\', host])
        try:
            win32wnet.WNetAddConnection2(0, None, unc, None, username, password)
        except Exception, err:
            if isinstance(err, win32wnet.error):
                # Disconnect previous connections if detected, and reconnect.
                if err[0] == 1219:
                    win32wnet.WNetCancelConnection2(unc, 0, 0)
                    return wnet_connect(host, username, password)
            raise err

    # Ensure required data files are present in Isilon landing zone of that application context(Eg: gwhp)
    def isLZFilesExist(SHAREPATH):
        wnet_connect(HOST, USER, PASS)        
        path = ''.join(['\\\\', HOST, '\\', SHAREPATH.replace(':', '$')])
        fileList = []
        if os.path.exists(path):
            for (dirpath, dirnames, filenames) in walk(path):
                fileList.extend(filenames)
                break
            if (len(fileList) > 1):
                print fileList
                print "\n\n *********************Required data files are present in the FileShare of that application context(Eg: gwhp)*********************"
                excelResult[0]='PASS'
            else:
                print "\n\n ********************* No files are present to start the Next Run *********************"
                sys.exit(0)
