请求参数

字段	类型	必填	说明
owner_address	string	是	出借方地址
receiver_address	string	是	接收方地址
balance	int64	是	撤销代理的冻结量（sun）
resource	enum	否	BANDWIDTH / ENERGY
permission_id	int32	否	多签权限 ID
visible	bool	否	地址格式

示例：

curl --request POST \
     --url https://nile.trongrid.io/wallet/undelegateresource \
     --header 'accept: application/json' \
     --header 'content-type: application/json' \
     --data '
{
  "owner_address":    "41dd791d6b49e190062d650e6a23c575510d35f2f9",
  "receiver_address": "4192ad11c1bf16b3b14b0bd6b5c7e2db73a0b5e83a",
  "balance":          1000000000,
  "resource":         "ENERGY"
}
'

响应

构造前校验 (owner, receiver) 之间在指定 resource 下存在足够的可撤销代理量。示例账户对该 receiver 无 ENERGY 代理记录，Nile 实抓返回：

{"Error": "class org.tron.core.exception.ContractValidateException : delegated Resource does not exist"}

校验通过时返回未签名 protocol.Transaction，结构示意（txID / ref_block_* / expiration / timestamp / raw_data_hex 含义同 /wallet/createtransaction）：
