上一篇文章 透過 Trongrid 準確獲取 Tron 區塊內的完整交易資料，抓到區塊的每一筆 txid ，這時候我們要去抓取該 txid 最原始的資料
這時候有分成一般轉 trx 跟 使用 contract 的轉帳，這邊就是紀錄一下
1. 這裡面我都透過 RestSharp 處理 關於 http 的相關事情
2. 這邊我舉例兩個 txid
2.1 純轉帳 trx - https://tronscan.org/#/transaction/497e9d02f78d22c9f19bab58b25384290d26b3eeac2362f0321d90b8515ea11a
我們透過呼叫 https://developers.tron.network/reference/wallet-gettransactionbyid
這個來測試，回應結果

這時候我們看到裡面資料有 to_address 跟 amount 這樣看起來要抓取比較簡單
2.2 合約轉帳 USDT - https://tronscan.org/#/transaction/ff67cb02dd3b358f4e8c0b1aa9de90e819ec9c564832d961619973f0d393ee9a

這時候竟然 to_address 跟 amount 消失了 但是，我們可以透過 contract.parameter.value.data 中間去取得接下來就是看我程式碼的部分
3. 取得該 txid 資料印出 from , to , amount
