Question

我想使用我的 rasbperrypi：拍照并将照片发送到 firebase 存储。

from google.cloud import storage
camera = PiCamera()
client = storage.Client()
bucket = client.get_bucket('gs://plante.appspot.com')


camera.start_preview()
sleep(5)
camera.capture('/home/pi/Desktop/culture/image.jpg')
camera.stop_preview()
sleep(5)

cultureBlob = bucket.get_blob('culture.jpg')
cultureBlob.upload_from_filename(filename='/home/pi/Desktop/culture/image.jpg')

但是我有这个错误：

pi@raspberrypi:~ $ python test.py
Traceback (most recent call last):
  File "test.py", line 31, in <module>
    client = storage.Client()
  File "/home/pi/.local/lib/python2.7/site-packages/google/cloud/storage/client.py", line 71, in __init__

google.auth.exceptions.DefaultCredentialsError: Could not automatically determine credentials. Please set GOOGLE_APPLICATION_CREDENTIALS or explicitly create credentials and re-run the application. For more information, please see https://cloud.google.com/docs/authentication/getting-started

不过，我安装了google云服务/

Answer 1

google.cloud 系统需要一些凭据。这可以是系统帐户或 OAuth。最简单的解决方案是创建一个包含您的帐户凭据的文件（A JSON blob）并设置环境变量 GOOGLE_APPLICATION_CREDENTIALS 以包含该文件的路径。然后运行你的软件。

使用您的帐户打开 Google Cloud Console，找到您的帐户凭据的定义位置。我真的不知道那是哪里..
