交易所通过eosjs进行充值与转账的代码片段是怎样的，很多新手对此不是很清楚，为了帮助大家解决这个难题，下面小编将为大家详细讲解，有这方面需求的人可以来学习下，希望你能有所收获。

连了两个远程测试节点

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

const actionUrl = 'http://junglehistory.cryptolions.io:18888' //只找到这个测试节点能够提供actions记录

//处理账户交易记录，判断从上一次扫描之后账户新增记录，并根据备注给用户充值
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' //伪代码

   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 //更新账户
       }
};

return actionHistory
}

//转账操作转账到账户accountName 'eosaccountb2';转账数额quantity '1.1234 EOS'
async function transfer(accountName,quantity) {
   let signatureProvider = new JsSignatureProvider([pkeys[0].privateKey]);
   let api = new Api({ rpc, signatureProvider, textDecoder: new TextDecoder(), textEncoder: new TextEncoder() });
   let result = await api.transact({
       actions: [{
           account: 'eosio.token',
           name: 'transfer',
           authorization: [{
               actor: pkeys[0].actor,
               permission: 'active',
           }],
           data: {
               from: pkeys[0].actor,
               to: accountName,   //提现地址
               quantity: quantity, //提现数量
               memo: '',
           },
       }]
   }, {
       blocksBehind: 3,
       expireSeconds: 30,
   });
   console.dir(result);
   let transaction_id = result.transaction_id
   let receipt= result.processed.receipt //抵押的net和cpu，记到数据库备份
   console.log('receipt===='+JSON.stringify(receipt))
   //insert into WITHDRAW()
};
