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。

我通常会remote_api_shell.py -s <mydomain>。

今天我尝试了它失败了，错误是：

oauth2client.client.ApplicationDefaultCredentialsError：The 应用程序默认凭据不可用。他们是可用的如果在Google Compute Engine中运行。否则，环境变量GOOGLE_APPLICATION_CREDENTIALS必须定义为指向a 定义凭据的文件。看到 https://developers.google.com/accounts/docs/application-default-credentials 了解更多信息。

我无法理解为什么它会问我。

wole输出是这个

Answer 1

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

Answer 2

转到API管理器下的开发人员控制台＆gt;＆gt;凭据（目前位于https://console.developers.google.com/apis/credentials?project=<<<Your App Id>>>）。
点击服务帐户，然后点击标有以下内容的按钮：＆＃34;生成新的JSON密钥＆＃34;。
将下载文件，将其保存在安全的地方。
将环境变量GOOGLE_APPLICATION_CREDENTIALS设置为指向运行remote_api_shell.py之前保存的文件

GAE：remote_api和Application Default Credentials
