Question

我正在尝试使用Google Drive SDK将Google云端硬盘中的所有数据下载到本地文件夹中。大多数文档都是在没有任何问题的情但有一些文件有奇怪的错误。

首先，所有这些文件都列在Files: list结果中。 Files: get会返回有关这些文件的信息。

我看到这些文件归我用来下载文档的用户所有：

[userPermission] => Google_Permission Object
    (
        [withLink] => 
        [kind] => drive#permission
        [name] => 
        [value] => 
        [id] => me
        [authKey] => 
        [etag] => "I8bbqc4qdR0X_1JlJgkO3gbuFf8/HQBSku0dMcS5bNfsSFuNdlHwJmk"
        [role] => owner
        [photoLink] => 
        [type] => user
        [additionalRoles] => 
        [selfLink] => https://www.googleapis.com/drive/v2/files/..../permissions/me
    )

但是当我尝试使用exportLinks之一导出这些文件时，我收到了错误。

HTTP状态404

文件：

Sorry, the file you have requested does not exist.

电子表格：

Spreadsheet not found
Error 404

HTTP状态401

在其他帐户上，我收到HTTP状态401错误：

Permission denied
Error 401

HTTP状态500

最后，HTTP Status 500存在很多错误：

Conversion failed unexpectedly
Error 500

主要问题 - 我可以解决这些问题吗？如果没有我可以向用户说明这些问题？

我可以告诉他们Google丢失了他们的数据（出现错误404时）吗？
我可以保证稍后会出现文件（出现错误500时）吗？
如果用户拥有自己的文档，错误401 Permission denied的可能性如何？

更新1：当我尝试导出时，它总是返回401

确保已实施正确的重试逻辑。见handling API errors。其中一些可能是短暂的问题。

该页面还讨论了特定错误代码的可能原因。例如，401可能表示您的令牌已过期。

Google文档导出问题401,404和500
