从 python 命令行调用 google api 时出错

Question

我对 python 很陌生。我正在尝试通过来自 google 云 shell 的 python 命令行调用 google 监控 API。我正在使用 python 2.7。在那之前我已经安装了

pip install --upgrade google-api-python-client

这是调用google监控的代码api

from googleapiclient.discovery import build

service = build('monitoring', 'v3', cache_discovery=True)
timeseries = service.projects().timeSeries().list(
            name="my-project",
            filter="metric.type=compute.googleapis.com/instance/cpu/utilization"
            aggregation_alignmentPeriod=86400s,
            # aggregation_crossSeriesReducer=api_args["crossSeriesReducer"],
            aggregation_perSeriesAligner="ALIGN_MEAN",
            aggregation_groupByFields="metric.labels.key",
            interval_endTime="2020-08-23T17:30:04.707Z",
            interval_startTime="2020-08-22T17:30:05.603000Z",
            pageSize=100
        ).execute()

我在 python 命令行中传递了适当的值，当我执行此行时

service = build('monitoring', 'v3', cache_discovery=True)

我收到以下错误：

>>>from googleapiclient.discovery import build
>>> service = build('monitoring', 'v3', cache_discovery=True)
Traceback (most recent call last):

    return app_identity.get_application_id()

    _, domain_name, display_app_id = _ParseFullAppId(full_app_id)
  File "/usr/lib/google-cloud-sdk/platform/google_appengine/google/appengine/api/app_identity/app_identity.py", line 436, in _ParseFullAppId
    psep = app_id.find(_PARTITION_SEPARATOR)
AttributeError: 'NoneType' object has no attribute 'find'

我不知道为什么会这样，有人可以帮助我吗？谢谢

Answer 1

我一直在我的 google 云 shell 上执行此操作，所以我认为这可以在不通过 GOOGLE_APPLICATION_CREDENTIALS 的情况下工作，因为我已经为计算引擎等其他 api 完成了此操作，但看起来我需要从 服务帐户 创建一个密钥，该帐户有权调用此 通过这个命令监控api，

gcloud iam service-accounts keys create --iam-account outputkey

完成后，我必须将此值导出到 GOOGLE_APPLICATION_CREDENTIALS 中的环境文件。
