• 源码：framework/src/main/java/org/tron/core/services/jsonrpc/TronJsonRpcImpl.java#getTransactionByBlockHashAndIndex
• 端口：FullNode 8545 / Solidity 8555

请求参数

位置	类型	必填	说明
params[0]	string	是	区块 hash
params[1]	string	是	块内交易下标，hex 编码（0x0 起）

curl -X POST https://nile.trongrid.io/jsonrpc \
  -H 'Content-Type: application/json' \
  -d '{"jsonrpc":"2.0","method":"eth_getTransactionByBlockHashAndIndex","params":["0x0000000003fe1ca05cf728c92ee79f5f2758c3e4e4ea88501826726880e8b81c","0x0"],"id":1}'

响应

TransactionResult（字段见 eth_getTransactionByHash）；块不存在或 index 越界返回 null。

下例为上面 curl 调用 Nile testnet 抓回的真实响应（同 eth_getTransactionByHash 中展示的合约调用交易）：
