上一篇文章 透過 Trongrid 準確獲取 Tron 區塊內的完整交易資料，抓到區塊的每一筆 txid ，這時候我們要去抓取該 txid 最原始的資料
這時候有分成一般轉 trx 跟 使用 contract 的轉帳，這邊就是紀錄一下
1. 這裡面我都透過 RestSharp 處理 關於 http 的相關事情
2. 這邊我舉例兩個 txid
2.1 純轉帳 trx - https://tronscan.org/#/transaction/497e9d02f78d22c9f19bab58b25384290d26b3eeac2362f0321d90b8515ea11a
我們透過呼叫 https://developers.tron.network/reference/wallet-gettransactionbyid
這個來測試，回應結果

}這時候我們看到裡面資料有 to_address 跟 amount 這樣看起來要抓取比較簡單

}這時候竟然 to_address 跟 amount 消失了 但是，我們可以透過 contract.parameter.value.data 中間去取得接下來就是看我程式碼的部分
3. 取得該 txid 資料印出 from , to , amount
static string ConvertHexToBase58Check(string hexAddress)
{
byte[] addressBytes = HexToBytes(hexAddress);
// 計算雙重 SHA-256 校驗碼
using (SHA256 sha256 = SHA256.Create())
{
byte[] hash1 = sha256.ComputeHash(addressBytes);
byte[] hash2 = sha256.ComputeHash(hash1);
// 取前 4 位作為校驗碼
byte[] checksum = hash2.Take(4).ToArray();
// 拼接地址與校驗碼
byte[] addressWithChecksum = addressBytes.Concat(checksum).ToArray();
// 轉換為 Base58
return EncodeBase58(addressWithChecksum);
}
}
static byte[] HexToBytes(string hex)
{
return Enumerable.Range(0, hex.Length / 2)
.Select(x => Convert.ToByte(hex.Substring(x * 2, 2), 16))
.ToArray();
}
static string EncodeBase58(byte[] input)
{
var Base58Chars = "123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyz";
var intData = new BigInteger(input.Reverse().Concat(new byte[] { 0 }).ToArray());
string result = "";
while (intData > 0)
{
int remainder = (int)(intData % 58);
intData /= 58;
result = Base58Chars[remainder] + result;
}
// 保留前導 0
foreach (byte b in input)
{
if (b == 0) result = '1' + result;
else break;
}
return result;
}

呼叫執行

//最後64位就是金額

Yesterday I wrote down the code. I bet I could be your hero. I am a mighty little programmer.
