我正嘗試使用Azure Python SDK爲Azure存儲中的容器創建有效的共享訪問簽名URL。我試圖生成它是立即生效，在30天后到期，並給予讀&整個容器（而不僅僅是BLOB）寫訪問。下面的代碼工作正常，並在最後打印最終的URL。我也在門戶中手動驗證容器和blob是否已成功創建。如何使用Azure Python SDK爲容器創建共享訪問簽名
然而，粘貼網址到瀏覽器後，我收到以下錯誤信息：
<?xml version="1.0" encoding="UTF-8"?>
-<Error>
<Code>AuthenticationFailed</Code>
<Message>Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature. RequestId:adecbe4e-0001-007c-0d19-40670c000000 Time:2015-12-26T20:10:45.9030215Z</Message>
<AuthenticationErrorDetail>Signature fields not well formed.</AuthenticationErrorDetail>
</Error>看來這個問題必須與這行代碼：
sasToken = blob_service.generate_shared_access_signature(containerName, None,SharedAccessPolicy(AccessPolicy(None, todayPlusMonthISO, "rw"), None))
以下是完整的代碼示例：
個from azure.storage.blob import BlobService
import datetime
from azure.storage import AccessPolicy, CloudStorageAccount, SharedAccessPolicy
containerName = "testcontainer"
blobName = "testblob.txt"
azureStorageAccountName = "" # Removed for publishing to StackOverflow
azureStorageAccountKey = "" # Removed for publishing to StackOverflow
blob_service = BlobService(account_name=azureStorageAccountName, account_key=azureStorageAccountKey)
blob_service.create_container(containerName)
blob_service.put_block_blob_from_text(containerName,blobName,"Hello World")
today = datetime.datetime.utcnow()
todayPlusMonth = today + datetime.timedelta(30)
todayPlusMonthISO = todayPlusMonth.isoformat()
sasToken = blob_service.generate_shared_access_signature(containerName, None,SharedAccessPolicy(AccessPolicy(None, todayPlusMonthISO, "rw"), None))
url = "https://" + azureStorageAccountName + ".blob.core.windows.net/" + containerName + "/" + blobName + "?" + sasToken
print(url)
任何想法如何解決這一問題？謝謝！
