PYTHON下載谷歌雲端硬盤電子表格

我想使用Python來訪問谷歌的API，從谷歌驅動下載電子表格，我借用谷歌API示例代碼，並做了一些改變它。但是，每次運行時，我總是有這個httpError返回，說我有「權限不足」。我在下面附上我的代碼，我想知道是否有人可以看看它，並讓我知道哪個部分是錯的。謝謝PYTHON下載谷歌雲端硬盤電子表格

您可能想要檢查用戶訪問文件的權限。在Google Drive API V3的Handling API Errors文檔中，

403：文件權限不足。用戶沒有足夠的文件{fileId}權限。

{ 
"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}." 
} 
}

您可能還需要檢查用戶訪問的級別由files.get檢索的元數據，並用它來你的UI更改爲只讀UI。

用戶許可和不正確使用Scopes可能導致Insufficient Permission響應。

這裏有一些相關的SO問題：
