PYTHON下载谷歌云端硬盘电子表格

我想使用Python来访问谷歌的API，从谷歌驱动下载电子表格，我借用谷歌API示例代码，并做了一些改变它。但是，每次运行时，我总是有这个httpError返回，说我有“权限不足”。我在下面附上我的代码，我想知道是否有人可以看看它，并让我知道哪个部分是错的。谢谢PYTHON下载谷歌云端硬盘电子表格

您可能想要检查用户访问文件的权限。在Google Drive API V3的Handling API Errors文档中，

403：文件权限不足。用户没有足够的文件{fileId}权限。

{ 
"error": { 
"errors": [ 
{ 
"domain": "global", 
"reason": "insufficientFilePermissions", 
"message": "The user does not have sufficient permissions for file {fileId}." 
} 
], 
"code": 403, 
"message": "The user does not have sufficient permissions for file {fileId}." 
} 
}

您可能还需要检查用户访问的级别由files.get检索的元数据，并用它来你的UI更改为只读UI。

用户许可和不正确使用Scopes可能导致Insufficient Permission响应。

这里有一些相关的SO问题：
