如何解决Azure TableService在生产中返回python ValueError,但未返回dev
我有运行GREAT的开发Python代码,该代码使用...
1 from azure.cosmosdb.table.tableservice import TableService
2 from azure.cosmosdb.table.models import Entity
...
85 table_service = TableService(connection_string = table_storage_connection_string)
86 perform_lookup = table_service.get_entity(mapping_table,'test','foo')
将代码复制到prod并更改...的值后
-
table_storage_connection_string
- Docs说可以使用
connection_string
。 - 已验证这是到表存储帐户的连接字符串
- 它正在使用
local.settings.json
/ Azure Portal App Settings中的Key Vault参考
- Docs说可以使用
-
mapping_table
...我收到错误消息:

为什么TableService()
在带有连接字符串的dev中工作正常,为什么在生产时需要Table Storage帐户名和帐户密钥或sas令牌?
编辑1:
用存储帐户的connection_string
和account_name
替换account_key
时,在下一行(89)出现 new 错误:>
1 from azure.cosmosdb.table.tableservice import TableService
2 from azure.cosmosdb.table.models import Entity
...
85 table_service = TableService(
86 account_name = table_storage_account_name,87 account_key = table_storage_account_key
88 )
89 perform_lookup = table_service.get_entity(mapping_table,'foo')
新错误:

有人在使用表存储之前解决了这个问题吗?
解决方法
我尝试重现您的错误,但是使用connection_string以及使用account_name和account_key都可以正常工作。
connection_string
同时包含AccountName
和AccountKey
,如下所示:
DefaultEndpointsProtocol=https;AccountName=<your-account-name>;AccountKey=<e60xxxxxxxxxxx==>;EndpointSuffix=core.windows.net
如果connection_string
不包含AccountName
或AccountKey
,则会出现错误。
错误(填充错误)与您的帐户密钥不正确有关。请在门户中重新生成密钥,然后尝试使用新密钥。
