查询实体时无需更改 string_to_sign ，请参见

No need to change string_to_sign when querying entity, see Authorization Header.

查询字符串应包含问号和comp参数(例如，?comp = metadata).查询字符串中不应包含其他任何参数.

The query string should include the question mark and the comp parameter (for example, ?comp=metadata). No other parameters should be included on the query string.

如果要使用PartitionKey获取整个实体，请将url更改为($需要编码为％24)

If you want to get whole entity using PartitionKey, change url to($ need encoding to %24)

https://${storage_account}.${table_store_url}/${table_name}?%24filter=PartitionKey%20eq%20'YourPartitionKey'

或者，如果您只想检索RowKey，请在其后附加&％24select = RowKey .

Or if you only want to retrieve RowKey, append &%24select=RowKey after that.

也 -H"Content-Length:0" 是没有用的，只需将其删除即可.

Also -H "Content-Length: 0" is useless, just delete it.
