我在快速入门页suggest上有与Google相似的代码。

    main()

首先，我创建了自己的秘密文件。然后在没有该文件的情况下执行'sheets.googleapis.com-python-quickstart.json'和.credentials文件夹，但遇到了sheets.googleapis.com-python-quickstart.json: No such file or directory错误

然后我在该文件夹上创建了空文件sheets.googleapis.com-python-quickstart.json，但遇到了另一个错误KeyError: '_module'。我甚至试图将我的秘密文件重命名为sheets.googleapis.com-python-quickstart.json - 同样的错误。我已从控制台和ipython笔记本执行此代码 - 同样的错误。删除.readonly更改SCOPES - 没有帮助

是否应该打开任何网页？我做错了什么？

我的问题看起来一样as - 但没有任何帮助，我的问题应该是有点不同的想法

Answer 1

首先应该下载适当的JSON，它应该是Web服务器。

其次，JSON应包含重定向网址"redirect_uris":"http://localhost:8080/"

该网址也应该添加到Google帐户中的设置中，您刚刚生成了该JSON

Google API：在调用get_credentials（）时表单KeyError：'_ module'
