从google drive 下载文件范例

テストから見ると、トークンの有効期間切れでも、トークンファイルがあれば、自動的に新しいアクセストークンを取得できます。（トークンファイルの中ではリフレッシュトークンがあります。）

それで、トークンの有効期間切れで処理が動かない、ということが発生しないと思います。

トークンファイルのデータ：

 

{
    "access_token": "ya29.a0AfH6SMBuzys-jdPhjP7imCWzuGlivXqVepyA8TI8sXSdiF7DYcCVtpeSwkyaXe9xCXONGxFukOCDskUj3-rzJAAMEWjBE3p3KxPoqCigXAyiKQz3K-b93tfDqsT2GVeUDkDN_n8CWJmlU_0P2DpYRzb3c38Ua79MhLTjs8CMAwA",
    "expires_in": 3599,
    "refresh_token": "1//0ezI2B9MKJ6DdCgYIARAAGA4SNwF-L9Ir3Cz15fhACf4OA9WP_3mCWk4yYh39CKDY3FuZt256UiG_IB5JCWTb87c54qGUaRaTGIs",
    "scope": "https://www.googleapis.com/auth/drive",
