Bitcoin: [问题] 如何获取入账手续费

创建于 2017-07-03 · 3评论 · 资料来源: bitcoin/bitcoin

你好。

我有一个问题，我找不到简单的解决方案。

我正在努力为传入的卡住交易自动执行 CPFP（子代为父代付费），并希望确保新交易有费用，因此每字节产生的费用将设置为当前网络条件，因此卡住交易（ s) 将很快得到确认。

问题是我无法确定通过gettransaction rpc 调用到达钱包的传入交易的费用。

下面是一个例子：

$ ./bitcoin-cli gettransaction yyy
{
  "amount": 0.00010000,
  "confirmations": 0,
  "trusted": false,
  "txid": "yyy",
  "walletconflicts": [
  ],
  "time": 1499083856,
  "timereceived": 1499083856,
  "bip125-replaceable": "yes",
  "details": [
    {
      "account": "user_123",
      "address": "xxxxxxxx",
      "category": "receive",
      "amount": 0.00010000,
      "label": "user_123",
      "vout": 0
    }
  ],
  "hex": "1234567"
}

比特币没有退还费用。仅当我发送传出交易时才会退还费用。

有什么方法可以确定为传入交易设置了多少费用（通过 JSON-RPC）？

谢谢你。

您将需要使用 getrawtransaction 然后进行数学计算。

所以以这个 txid 为例：e198d4b193644116d9df0b9d65c4346a9f4d6214a46ffba8c0b2fd6999eda314

现在你需要做的是计算费用的数量，就是查看vin里面并取vout数量。所以在这个例子中，vout 数是 0。然后你去 vout 并将所有输出的值加在一起。

现在您必须对 vin txid 执行另一个 getrawtransaction。在我们的例子中，这会给我们这个：

                "n": 0,
                "scriptPubKey": {
                    "asm": "OP_DUP OP_HASH160 941cae6b6c65cb2b45322c5a1b5c62c14fda1244 OP_EQUALVERIFY OP_CHECKSIG",

                    ]
                }
            },
            {
                "value": 25.00000000,
                "n": 1,
                "scriptPubKey": {
                    "asm": "OP_HASH160 53686151ca689cc39c42c6c63c774ec76ac12856 OP_EQUAL",
                    "hex": "a91453686151ca689cc39c42c6c63c774ec76ac1285687",
                    "reqSigs": 1,
                    "type": "scripthash",
                    "addresses": [
                        "39J33vf83H4YdPvnDwiWYBzhoSWqVDhQP9"
                    ]
                }
            }
        ],
        "blockhash": "0000000000000000013602fbbd4791c0f4b7e612d11ccd4d825cc0fc34318f39",
        "confirmations": 541,
        "time": 1498901391,
        "blocktime": 1498901391
    },
    "error": null,
    "id": null
}

所以在这里，你必须寻找的是，在 vout 中，n 值等于你得到的前一个数字，所以在我们的例子中它是 0。你得到这个输出的值，即 7.04418967 BTC。现在来计算费用，你用这个数字减去你之前得到的值，这给你：

费用 = 7.04418967 - (4.00000000 + 3.04192967)
费用 = 0.00226 BTC

希望这会帮助你。

费用 = 7.04418967 - (4.00000000 + 3.04192967)
费用 = 0.00226 BTC

希望这会帮助你。

鉴于这是（技术上）公开可用的信息-如果可以计算费用然后将其添加到getrawtransaction返回的结果对象中，那就太好

这也将显着减少用于计算费用的服务器上的负载，因为消费者不再需要为任何单笔交易多次访问比特币节点（假设他们想要计算费用）

是的，我也想说费用应该显示在那里
