GAE：remote_api和应用程序默认凭证 [英] GAE: remote_api and Application Default Credentials

问题描述

由于今天我一直使用 remote_api （python）访问数据存储GAE。

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

今天我试过了，但是失败了，错误是：
$ b

oauth2client.client.ApplicationDefaultCredentialsError：
应用程序默认凭证不可用。如果在Google Compute Engine中运行，它们可用
。否则，环境
变量GOOGLE_APPLICATION_CREDENTIALS必须定义为指向定义凭据的
文件。请参阅
https://developers.google.com/accounts/docs/

我不明白为什么它会问我这个问题。

输出是这样的

解决方案

解决方案是运行 gcloud auth login ，然后再次授予

Since today i've been using remote_api (python) to access the datastore on GAE.

I usually do remote_api_shell.py -s <mydomain>.

Today I tried and it fails, the error is:

oauth2client.client.ApplicationDefaultCredentialsError: The Application Default Credentials are not available. They are available if running in Google Compute Engine. Otherwise, the environment variable GOOGLE_APPLICATION_CREDENTIALS must be defined pointing to a file defining the credentials. See https://developers.google.com/accounts/docs/application-default-credentials for more information.

I cannot understand why it asks me that.

the wole output is this

stefano@~/gc$ remote_api_shell.py -s ....

解决方案

The solution is to run gcloud auth login in the shell and give the grant again
