交易所經過eosjs進行充值與轉帳的代碼片斷

連了兩個遠程測試節點

const rpcUrl = 'http://jungle2.cryptolions.io:80'

const actionUrl = 'http://junglehistory.cryptolions.io:18888' //只找到這個測試節點可以提供actions記錄

 

//處理帳戶交易記錄，判斷從上一次掃描以後帳戶新增記錄，並根據備註給用戶充值
async function dealActions(accountName) {
    let rpcH = new JsonRpc(actionUrl, { fetch });
    let actionHistory = await rpcH.history_get_actions(accountName);
    let latestTime = 'select TRANS_TIME from RECHARGE where IFLAST=yes' //僞代碼

    for (let i in actionHistory.actions) {  
        var block_time = actionHistory.actions[i].block_time    
        if(block_time > latestTime){
            let memo = actionHistory.actions[i].action_trace.act.data.memo
            let quantity = actionHistory.actions[i].action_trace.act.data.quantity
            let from = actionHistory.actions[i].action_trace.act.data.from
            let to = actionHistory.actions[i].action_trace.act.data.to
            let trx_id = actionHistory.actions[i].action_trace.trx_id
            let global_action_seq = actionHistory.actions[i].global_action_seq
            let block_num = actionHistory.actions[i].block_num
            let producer_block_id = actionHistory.actions[i].producer_block_id
            //let to = actionHistory.actions[i].action_trace.act.data.to
            
            console.log('memos'+i+'='+memo)
            //insert into RECHARGE values()  //插入充值表
            //update USER_ACCOUNT set BALANCE AVAILABLE_BALANCE where USER_ID = 0 //更新帳戶
        }
      };

    return actionHistory
}

 //轉帳操做 轉帳到帳戶accountName 'eosaccountb2';轉帳數額quantity '1.1234 EOS'
