【问题描述】：

使用 Google App Engine，我正在尝试将文件“a.txt”插入到我的 Google 驱动器中。查看 InsertDrive 页面的页面源时出现的错误是

HttpError 401“需要登录” main.InsertDrive 对象在 0x10f884b0 处的绑定方法 InsertDrive.error

注意：我通过在 Jinja 模板中显示 MainHandler 类的 url 从我的 MainHandler 类调用类 InsertDrive。

【解决方案1】：

我试过你的代码，如果你尝试上传文件，问题就解决了而不是使用此代码

file = service.files().insert(
                body=body,
                media_body=media_body).execute()

你用这个

file = service.files().insert(
                body=body,
                media_body=media_body).execute(http=decorator.http())

不同之处在于您指定将用于上传的凭据是您使用装饰器进行身份验证的那些。

希望对你有帮助
