Etherscan :如何获得交易费用？
例如:打开这个https://etherscan.io/tx/0xcb1e3530950cf2c43a307bcb5645ae71a12c76a60831617badd04aea3efe68aa
是随机的
我在网页上看到了这些信息：
Gas Limit:
136,500
Gas Used by Transaction:
35,531 (26.03%)
Gas Price:
0.000000008 Ether (8 Gwei)
Transaction Fee:
0.000284248 Ether ($0.05)我知道fee = gas_price x used_gas => 0.000000008 x 35,531 = 0.000284248 eth
太完美了。
I有兴趣通过api阅读以实际货币转换的交易费，就像您看到有一个$0.05
我不能一个api调用返回此信息的以太扫描。
我能做些什么才能得到这些信息？
呼叫
我只得到这些信息

}哪里
小数中的"gas": "0x21534" =>是136,500
小数中的"gasPrice"○: "0x1dcd65000" =>是8,000,000,000
这就是结果

}我在这里
"cumulativeGasUsed": "0x778412" => 7,832,594 [ what ??? ]
"gasUsed": "0x8acb" => 35,531 [ gas used by this transaction]因此，要重建网页信息，我需要2个api调用，以检索汽油价格和使用的天然气。
但我没有eth的报价，这才是我真正需要的

例如，您可以使用CryptoCompare API：
const ETH_AMOUNT = "0.000284248";
const request = require("request");
const Decimal = require("decimal.js");
request.get("https://min-api.cryptocompare.com/data/price?fsym=ETH&tsyms=USD", function(error, response, body) {
if (error)
throw new Error(error);
else if (!response)
throw new Error("no response");
else if (response.statusCode != 200)
throw new Error("bad response");
else
convert(JSON.parse(body).USD);
});
function convert(usdRate) {
const USD_AMOUNT = new Decimal(ETH_AMOUNT).mul(usdRate);
console.log(USD_AMOUNT.toFixed(2 /* decimal places */));

我只是在做一件类似的事情(但在发送tx之前，我会打电话)。
这个过程是为了
- 获取您想要的货币的平均价格。即美元。Coingecko有一个免费的api，返回交易所的价格列表。我用平均价格计算出当前的价格。
- 拿到每台的价格。也就是说，为了把美元送到贵公司，你可以做
avgPriceUSD / 1000000000。这将给你每克威美元。有了这个，您现在可以进行查找了。 - 加用的汽油。看来你已经有了一堆这些答案。
- 只需将每克威的气体乘以你所用的气体(单位为克威)。
如果你试图在过去为tx弄清楚这一点，你需要在某个时间点上得到这个价格。(您可以使用免费的coingecko api或您的首选项。)
我希望我正确地理解了你原来的问题。读回去，我可能会的。如果不是因为我得走了，我就把这个给删了。LOL。

我不知道在此期间您是否能够解决这个问题，但从January 7 2022eth_getTransactionReceipt>开始，API调用D0返回一个名为effectiveGasPrice的字段，该字段对应于从eth_getTransactionByHash API调用(即"0x1dcd65000" )返回的相同值。
让我们进行另一项事务，在本例中：
0xf23766719c61461673d9e6f5cdc1e9ba42c958c07b924bfb9809cd58c244b4c0
来自effectiveGasPrice的eth_getTransactionReceipt：<#>0x19bbced2d3
来自gasPrice的eth_getTransactionByHash：0x19bbced2d3
换句话说，eth_getTransactionReceipt足以收回汽油价格和使用的天然气。
