所以我使用 dev_appserver.py 在本地运行我的 google 端点。 我使用 API Explorer 来测试应用程序。

我用来创建服务，所以我可以调用 API 的代码如下:

from apiclient.discovery import build 
from oauth2client.client import GoogleCredentials
credentials = GoogleCredentials.get_application_default()
service = build('speech', 'v1beta1', credentials=credentials)

我收到 SSL 错误(无效和/或缺少 SSL 证书)，即使当我通过浏览器访问指定的 URL 时它工作正常(即显示绿色挂锁)。

我不确定发生了什么变化，但不久前它还可以正常工作。

我尝试禁用 SSL 检查，但未能成功。

完整日志如下:

任何想法可能导致此问题？

我是否必须“安装”或更新 python 使用的 SSL 证书？

最佳答案

根据App Engine issue 13477似乎在 urlfetch_cacerts.txt 中找到了一些证书包含在 App Engine Python SDK 中/gcloud-sdk已过期2017-01-01 .

作为临时解决方法，您可以替换 <your-cloud-sdk-path>/platform/google_appengine/lib/cacerts/urlfetch_cacerts.txt 的内容与 https://curl.haxx.se/ca/cacert.pem

关于python - 调用 apiclient.discovery.build 时 URL 的 SSL 证书无效和/或丢失，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/41421007/
