谷歌雲存儲訪問客戶端API

我有一個很艱難的時期讓應用程序的默認Credientials /OAuth2.0的事情在我的計劃工作...谷歌雲存儲訪問客戶端API

背景：

我有一個傳感器裝置收集圖像，我想將這些圖像存儲在谷歌雲存儲中。理想情況下，代碼只需按下一個按鈕即可運行，因此在程序運行時需要執行授權。

從閱讀和重新閱讀的文檔，這是我迄今打算：

from oauth2client.client import GoogleCredentials 
from google.cloud import storage 
import google.auth 
import os 

# Establish cloud credientials with a locally 
# stored service account key 
home_path = os.path.expanduser('~') + "/Project/" 
auth_file = "<service account access key file>.json" 
auth_file_path = home_path + auth_file 

# I'm trying two different ways to verify my credentials.. 
os.environ['GOOGLE_APPLICATION_CREDENTIALS'] = auth_file_path 
credentials, project_id = google.auth.default() 

# Get storage bucket for image files 
storage = storage.Client(project_id) 
bucket = storage.lookup_bucket('bucket0000')

其結果是，我得到一個回溯錯誤：

Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
    File "<string>", line 110, in <module> 
    File "/Users/joshua/anaconda/lib/python3.5/site-packages/google/cloud/storage/client.py", line 193, in lookup_bucket 
    return self.get_bucket(bucket_name) 
    File "/Users/joshua/anaconda/lib/python3.5/site-packages/google/cloud/storage/client.py", line 173, in get_bucket 
    bucket.reload(client=self) 
    File "/Users/joshua/anaconda/lib/python3.5/site-packages/google/cloud/storage/_helpers.py", line 99, in reload 
    _target_object=self) 
    File "/Users/joshua/anaconda/lib/python3.5/site-packages/google/cloud/_http.py", line 303, in api_request 
    error_info=method + ' ' + url) 
google.cloud.exceptions.Forbidden: 403 Caller does not have storage.buckets.get access to bucket bucket0000. (GET https://www.googleapis.com/storage/v1/b/bucket0000?projection=noAcl)

地方似乎我仍被視爲匿名用戶（根據追蹤中的googleapis.com鏈接）

{ 
"error": { 
    "errors": [ 
    { 
    "domain": "global", 
    "reason": "required", 
    "message": "Anonymous users does not have storage.buckets.get access to bucket bucket0000.", 
    "locationType": "header", 
    "location": "Authorization" 
    } 
    ], 
    "code": 401, 
    "message": "Anonymous users does not have storage.buckets.get access to bucket bucket0000." 
} 
}

再次嘗試，這次google.auth，我創建了一個證書變量，並觀察什麼打印似乎有效：<oauth2client.service_account._JWTAccessCredentials object at 0x107df0358>

我試圖把這個憑證變量爲storage.Client（），但似乎並不上班。

# Get storage bucket for image files 
storage = storage.Client(project_id, credentials=credentials) 
bucket = storage.lookup_bucket('bucket0000') 

>>> Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
    File "<string>", line 6, in <module> 
    File "/Users/joshua/anaconda/lib/python3.5/site-packages/google/cloud/storage/client.py", line 59, in __init__ 
    _http=_http) 
    File "/Users/joshua/anaconda/lib/python3.5/site-packages/google/cloud/client.py", line 212, in __init__ 
    Client.__init__(self, credentials=credentials, _http=_http) 
    File "/Users/joshua/anaconda/lib/python3.5/site-packages/google/cloud/client.py", line 126, in __init__ 
    raise ValueError(_GOOGLE_AUTH_CREDENTIALS_HELP) 
ValueError: This library only supports credentials from google-auth-library-python. See https://google-cloud-python.readthedocs.io/en/latest/google-cloud-auth.html for help on authentication with this library

當然，這回溯指導我的頁面google-cloud-python.readthedocs.io ......不存在......

任何方式來獲得API調用到雲存儲在沒有使用控制檯/網絡登錄的情況下工作？

非常感謝！

您真的在使用Google App Engine嗎？從代碼中不清楚。針對應用引擎和其他應用的雲端存儲身份驗證有所不同，因此務必要清楚這一點。 – snakecharmerb

看來你沒有給你的憑證管理存儲的權限。您可以在IAM或每個桶下輕鬆應用它。
