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，底层已自动封装签名操作。以下列举常用方法，其他方法请参考TRON官方项目文档。

• GetAccount

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

• GetAccountResource

  
              javascript
              
              
  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

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

• GetAssetIssueByName

  
              javascript

• GetNowBlock

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

• GetBlockByNum

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

• GetTransactionByID

  
              javascript
              
              
  exchange.IO("api", "tron", "GetTransactionByID", "05a8fae2cd1cbf36b61d12e219588d25b4826436f055f93388a96e620ec3f3f2")   // 根据交易哈希值获取Transaction
  

• TRC20ContractBalance

  
              javascript
              
              
  exchange.IO("api", "tron", "TRC20ContractBalance", "TKCG...", "TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t")   // 获取钱包 USDT 余额，注意返回的数据未经精度处理，例如返回数据为：```6890251```，即```6.890251 USDT```。
  

• TriggerConstantContract

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

• TRC20Call

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

• Transfer

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