前陣子分享了兩篇文章，透過 Trongrid 取得 Tron 一個指定區塊中的交易資料 、透過 Trongrid 取得 Tron 區塊內 USDT 交易資料
但是一直有一個疑問，我撈取的資料，為何跟 Tronscan 上面的區塊數字不同，就以 https://tronscan.org/#/block/64991111
來看明明就有 388 筆資料，但是我之前卻只抓到 159 ...
後來我找一下找到這個 https://developers.tron.network/reference/getblockbynum 可以透過撈取該
Block 的資料
只好實際來測試一下
1. 這裡面我都透過 RestSharp 處理 關於 http 的相關事情
2. 接下來就是抓取的 C# Code
2.1 這邊我規劃一隻 function 直接呼叫 getblockbynum 並且，直接轉成 BlockNumResponse 物件
<![CDATA[
var blockInfo = GetTrc20BlockByNum("64991111");
foreach (var transaction in blockInfo.transactions)
{
var owner_address = ConvertHexToBase58Check(transaction.raw_data.contract[0].parameter.value.owner_address);
Console.WriteLine("txid:" + transaction.txID + ", from:" + owner_address);
}
Console.WriteLine("Block Data Count:" + blockInfo.transactions.Count);
/// <summary>
/// Block num
/// </summary>
/// <param name="blockNumber"></param>
/// <returns></returns>
private static BlockNumResponse GetTrc20BlockByNum(string blockNumber)
{
var client = new RestClient("https://api.trongrid.io/walletsolidity/getblockbynum");
var request = new RestRequest("?num=" + blockNumber, Method.Get);
var response = client.Execute(request).Content;
var result = JsonConvert.DeserializeObject<BlockNumResponse>(response);
return result;
}
]]>
2.2 BlockNumResponse 物件
<![CDATA[
public class BlockNumResponse
{
public string blockID { get; set; }
public BlockHeader block_header { get; set; }
public List<Transaction> transactions { get; set; }
public class BlockHeader
{
public RawData raw_data { get; set; }
public string witness_signature { get; set; }
}
public class Transaction
{
public List<Ret> ret { get; set; }
public List<string> signature { get; set; }
public string txID { get; set; }
public class Ret
{
public string contractRet { get; set; }
}
public RawData raw_data { get; set; }
public string raw_data_hex { get; set; }
}
public class RawData
{
public int number { get; set; }
public string txTrieRoot { get; set; }
public string witness_address { get; set; }
public string parentHash { get; set; }
public int version { get; set; }
public long timestamp { get; set; }
public List<Contract> contract { get; set; }
public string ref_block_bytes { get; set; }
public string ref_block_hash { get; set; }
public object expiration { get; set; }
public int? fee_limit { get; set; }
public class Contract
{
public Parameter parameter { get; set; }
public string type { get; set; }
public int Permission_id { get; set; }
public class Parameter
{
public Value value { get; set; }
public string type_url { get; set; }
public class Value
{
public object balance { get; set; }
public string resource { get; set; }
public string receiver_address { get; set; }
public string owner_address { get; set; }
public string data { get; set; }
public string contract_address { get; set; }
public long? amount { get; set; }
public string to_address { get; set; }
public string asset_name { get; set; }
public int? call_value { get; set; }
}
}
}
}
}
]]>
這裡面的 transaction 物件大概是長這樣
2.3 因為其中 owner_address 並不是用 trc20 標準錢包的顯示，所以有一些轉換的 functions 這邊之前有人反應過
這邊我提供不需要 TronNet 的轉換版本
<![CDATA[
//C
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;
}
]]>
result :
看起來結果事一樣的，這時候你就問我了他似乎給的資訊不多，那怎麼辦看來就是要用 txid 在去 trongrid 查詢該交易的詳細狀況
記錄到這邊希望有幫助到你..
