编码/解码

当交易所对象设置为Web3并选择TRON时，编码/解码等操作与以太坊的Web3交易所对象保持一致。 - encode：

  let ret = exchange.IO("encode", "address", "TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t")
  Log(ret) // ret: 000000000000000000000000a614f803b6fd780986a42c78ec9c7f77e6ded13c , 对USDT代币的TRON地址进行编码。

• decode：

  
  let data = "0000000000000000000000000000000000000000000000000000000000000020000000000000000000000000000000000000000000000000000000000000000a5465746865722055534400000000000000000000000000000000000000000000"
  let ret = exchange.IO("decode", "string", data)
  Log(ret)  // ret: Tether USD , 类似于ParseTRC20StringProperty的功能
  

• encodePacked：

  
  let ret = exchange.IO("encodePacked", "address", "TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t")
  Log(ret)  // ret: a614f803b6fd780986a42c78ec9c7f77e6ded13c
