我已经阅读了很多关于此的问题，但没有找到有效的解决方案:(
$ appcfg.py download_data --url=http://THING.appspot.com/_ah/remote_api --filename=backup1 .
08:47 PM Application: THING

所以我有几个关于发生了什么的问题：
- 为什么这不要求我输入密码，而在我看到的几乎所有其他问题中都这样做？是因为我已经上传了我的应用程序的新版本并登录了吗？
- 为什么有些人必须将 application='s~THING' 放在他们的命令行中（对我没有帮助）。
- 我使用 gmail 地址作为我的管理员，所以大概这意味着它与作为其他类似问题的答案给出的任何 OpenID 错误无关？
- 我
builtins: - remote_api: on在我的 app.yaml 中有（在这个目录中 - 因此是“。”，对吗？），我需要放入一个处理程序吗？ - /_ah/remote_api 的请求转到我的主 ("/.*") 处理程序！这是问题的原因吗？
- 我该如何解决这些问题？
编辑：塞巴斯蒂安好心地指出我正确的方向，但我现在有这个错误：
