GAE:remote_api和Application Default Credentials

Question

从今天开始,我一直在使用remote_api(python)来访问GAE上的数据存储区.

我经常这样做remote_api_shell.py -s <mydomain>.

今天我尝试了它失败了,错误是:

oauth2client.client.ApplicationDefaultCredentialsError:应用程序默认凭据不可用.如果在Google Compute Engine中运行,则可以使用它们.否则,必须定义环境变量GOOGLE_APPLICATION_CREDENTIALS,指向定义凭证的文件.有关 详细信息,请参阅 https://developers.google.com/accounts/docs/application-default-credentials.

我不明白为什么它问我.

wole输出就是这个

Answer 1

解决方案是gcloud auth login在shell中运行并再次提供授权

Answer 2

1. 转到API管理器>>凭据下的开发者控制台（当前位于https://console.developers.google.com/apis/credentials?project=<<<Your App Id>>>）。
2. 单击服务帐户，然后单击标记为“生成新的JSON密钥”的按钮。
3. 将下载文件，并将其保存在安全的地方。
4. 将环境变量GOOGLE_APPLICATION_CREDENTIALS设置为指向您在运行remote_api_shell.py之前保存的文件
