Azure TableService() returns python 产品中的 ValueError，但不是开发中的
Azure TableService() returns python ValueError in prod, but not dev
我有开发 Python 代码 运行 很棒，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 并更改值后...
table_storage_connection_string
- Docs 说用
connection_string 就可以了。
- 已验证这是 Table 存储帐户的连接字符串
- 它在
local.settings.json/Azure 门户应用设置 中使用 Key Vault 引用
mapping_table
...我得到错误：

Microsoft.Azure.WebJobs.Host.FunctionInvocationException: Exception while executing function: Functions.my-func-prod
为什么 TableService() 在带有连接字符串的开发中工作得很好，在产品中需要 Table 存储帐户名称和帐户密钥或 sas 令牌？
编辑 1：
当 connection_string 替换为存储帐户的 account_name 和 account_key 时，我在后续行中收到 new 错误（ 89):
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, 'test', 'foo')
新错误：

有人用 Table 存储解决过这个问题吗？
我试图重现您的错误，但使用 connection_string 以及使用 account_name 和 account_key 都运行良好。
connection_string同时包含AccountName和AccountKey，看起来像这样：
DefaultEndpointsProtocol=https;AccountName=<your-account-name>;AccountKey=<e60xxxxxxxxxxx==>;EndpointSuffix=core.windows.net
如果connection_string不包含AccountName或AccountKey，就会出现错误。
错误（填充不正确）与您的帐户密钥不正确有关。请在门户中重新生成密钥并尝试使用新密钥。
