获取波场（Tron）钱包TRX、USDT余额和剩余带宽、能量 - 笔记

随手记录常用接口的实现，方便以后复制。

在线获取 TRX 和 USDT 余额

private static Tuple<decimal, decimal> GetBalanceByAddressByOnline(string address) {
    var tuple = new Tuple<decimal, decimal>(0, 0);

    var responseString = HttpClientHelper.Get($"https://api.trongrid.io/v1/accounts/{address}"); //接口地址
    if (string.IsNullOrEmpty(responseString)) return tuple;

    var responseObject = JsonConvert.DeserializeObject<dynamic>(responseString);
    if (responseObject == null) return tuple;

    if ((bool)responseObject.success != true) return tuple;
    if (responseObject.data == null || responseObject.data.Count == 0) return tuple;

    var obj = responseObject.data[0];
    if (obj == null) return tuple;

    var trxBalance = new decimal(0); // TRX 余额

    var balance = obj.balance;
    if (balance != null) trxBalance = (long)balance / new decimal(1000000);

    var etherBalance = new decimal(0); // USDT 余额

    var trc20Tokens = obj.trc20;
    if (trc20Tokens != null) {
        foreach (var trc20Token in trc20Tokens) {
            var tokenBalance = trc20Token.TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t; // USDT 合约地址
            if (tokenBalance != null) etherBalance = (long)tokenBalance / new decimal(1000000);
        }
    }

      return new Tuple<decimal, decimal>(trxBalance, etherBalance);
  }

在线获取带宽和能量

private static Tuple<long, long> GetAccountResource(string address) {
    var tuple = new Tuple<long, long>(0, 0);

    var requestObj = new { address = address, visible = true };
    var responseString = HttpClientHelper.Post("https://api.trongrid.io/wallet/getaccountresource", JsonConvert.SerializeObject(requestObj), Encoding.UTF8); //接口地址
    if (string.IsNullOrEmpty(responseString)) return tuple;

    var responseObject = JsonConvert.DeserializeObject<dynamic>(responseString);
    if (responseObject == null) return tuple;

    var freeNetLimit = 0L; //免费带宽数量
    if (responseObject.freeNetLimit != null) freeNetLimit = Convert.ToInt64(responseObject.freeNetLimit);

    var freeNetUsed = 0L; //已使用免费带宽数量
    if (responseObject.freeNetUsed != null) freeNetUsed = Convert.ToInt64(responseObject.freeNetUsed);

    var netLimit = 0L; //质押获取的带宽数量
    if (responseObject.NetLimit != null) netLimit = Convert.ToInt64(responseObject.NetLimit);

    var netUsed = 0L; //已使用质押获取的带宽数量
    if (responseObject.NetUsed != null) netUsed = Convert.ToInt64(responseObject.NetUsed);

    var energyLimit = 0L; //质押获取的能量数量
    if (responseObject.EnergyLimit != null) energyLimit = Convert.ToInt64(responseObject.EnergyLimit);

    var energyUsed = 0L; //已使用质押获取的能量数量
    if (responseObject.EnergyUsed != null) energyUsed = Convert.ToInt64(responseObject.EnergyUsed);

    return new Tuple<long, long>(netLimit + freeNetLimit - netUsed - freeNetUsed, energyLimit - energyUsed);
}

HttpClientHelper 类 封装

public static class HttpClientHelper {
      public static string Post(string url, string requestBody, Encoding encoding, int timeout = 12000) {
          var httpWebResponse = Post((HttpWebRequest)WebRequest.Create(url), requestBody, encoding, timeout);

          using var stream = httpWebResponse.GetResponseStream();
          using var streamReader = new StreamReader(stream);

          return streamReader.ReadToEnd();
      }

      private static HttpWebResponse Post(HttpWebRequest httpWebRequest, string requestBody, Encoding encoding, int timeout = 12000) {
          var bytes = encoding.GetBytes(requestBody);

          httpWebRequest.Method = "POST";
          httpWebRequest.ContentType = "application/json";
          httpWebRequest.ContentLength = bytes.Length;
          httpWebRequest.Timeout = timeout;
          httpWebRequest.Accept = "application/json";
          httpWebRequest.Headers.Set("TRON-PRO-API-KEY", "80a8b20f-a917-43a9-a2f1-809fe6eec0d6");
          using (var stream = httpWebRequest.GetRequestStream()) {
              stream.Write(bytes, 0, bytes.Length);
          }

          return (HttpWebResponse)httpWebRequest.GetResponse();
      }
  }
