调用TRON的RPC方法

使用exchange.IO()函数调用TRON的RPC方法。对于需要签名的方法，底层已经自动封装了签名操作。这里列举一些常用方法，其余方法可以具体查阅TRON官方项目资料。 - GetAccount

  exchange.IO("api", "tron", "GetAccount", "TKCG...")   // "TKCG..."是TRON钱包地址，该函数返回"TKCG..."地址的账户信息。

• GetAccountResource

  
  exchange.IO("api", "tron", "GetAccountResource", "TKCG...") // 获取指定钱包地址的资源，包括能量和带宽。
  

• GetContractABI

  
  exchange.IO("api", "tron", "GetContractABI", "TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t")  // 拉取 USDT TRC20合约ABI
  

• GetAssetIssueByName

  
  exchange.IO("api", "tron", "GetAssetIssueByName", "TRX")  // 根据token名称获取token资产信息
  

• GetNowBlock

  
  exchange.IO("api", "tron", "GetNowBlock")   // 获取当前区块信息
  

• GetBlockByNum

  
  exchange.IO("api", "tron", "GetBlockByNum", 70624300)
  

• GetTransactionByID

  
  exchange.IO("api", "tron", "GetTransactionByID", "05a8fae2cd1cbf36b61d12e219588d25b4826436f055f93388a96e620ec3f3f2")   // 根据具体哈希值获取Transaction
  

• TRC20ContractBalance js exchange.IO("api", "tron", "TRC20ContractBalance", "TKCG...", "TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t") // 获取钱包 USDT 的余额，注意数据是没有经过精度处理的可读数据，例如返回的数据为：6890251，即6.890251 USDT

• TriggerConstantContract

  
  function main() {
    let ret = exchange.IO("api", "tron", "TriggerConstantContract", "", "TSUUVjysXV8YqHytSNjfkNXnnB49QDvZpx", "token0()", "")  // 调用某个智能合约的token0()方法，TriggerConstantContract用于调用read方法
    let data = exchange.IO("decode", "address", Encode("raw", "raw", "hex", ret["constant_result"][0]))                        // 解码数据
    return data                                                                                                                // data: 0x891cdb91d149f23b1a45d9c5ca78a88d0cb44c18                  
  }
  

• TRC20Call

  
  function main() {
    let ret = exchange.IO("api", "tron", "TRC20Call", "", "TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t", "0x06fdde03", true, 0)         // 使用TRC20Call调用read方法0x06fdde03
    let data = Encode("raw", "raw", "hex", ret.constant_result[0])
    return exchange.IO("api", "tron", "ParseTRC20StringProperty", data)                                                        // Tether USD
  }
  

• Transfer

  
  exchange.IO("api", "tron", "Transfer", "TWTbn...", "TKCG...", 1000000)            // 使用Transfer方法转账TRX，从"TWTbn..."转到"TKCG..."，1000000即1TRX。
