英文:
Retrieve user's current delegation and rewards in Flow programmatically using user_id
问题
我想知道如何通过程序化方式在流程中传递用户 ID 来获取特定用户的当前委托和奖励！？我已尝试过 JavaScript SDK。但我猜它没有针对质押和奖励余额的支持
我需要关于此的帮助

This code is dervied from several scripts over here https://github.com/onflow/flow-core-contracts/tree/master/transactions
You have to call that script in any flow SDK and it should give you out the DelegatorInfo struct defined here https://github.com/onflow/flow-core-contracts/blob/3198bb0d01351daaf207e82c930da5fc0cc60fa8/contracts/FlowIDTableStaking.cdc#L379
