第一種，使用eosjs開發，適用于用戶輸入私鑰方式，不安全，易造成私鑰泄露。

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

const { Api, JsonRpc, RpcError, JsSignatureProvider } = require('eosjs');

const ecc = require('eosjs-ecc');

const fetch = require('node-fetch');

const { TextDecoder, TextEncoder } = require('text-encoding');

const rpc = new JsonRpc(rpcUrl, { fetch });

//轉賬操作 轉賬到賬戶accountName 'eosaccountb2';轉賬數額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,//提現地址

quantity: quantity, //提現數量

memo: '',

},

}]

}, {

blocksBehind: 3,

expireSeconds: 30,

});

console.dir(result);

};

第二種，使用nodeos api+wallet api開發，適合用于公共賬戶給不同用戶轉賬。相當于用wallet錢包服務來做密鑰管理，隱藏了私鑰，代碼中只需提供公鑰和錢包服務地址即可。

async function transfer() {

try {

let actor = "eosaccountaa"

let transferTo = "eosaccountbb"

let quantity = "1.1234 EOS"

let memo = "hi heere"

let blocksBehind = 3

let expireSeconds = 100

let info = await rpc.get_info();

if (info != null && info.chain_id != null && info.head_block_num != null) {

let chain_id = info.chain_id;

let head_block_num = info.head_block_num - blocksBehind;

let block = await get_block(head_block_num);

if (block != null && block.ref_block_prefix != null && block.timestamp != null) {

let data = await abi_json_to_bin(actor, transferTo, quantity, memo)

if (data != null) {

let transactions = {

"max_net_usage_words": 0,

"max_cpu_usage_ms": 0,

"delay_sec": 0,

"context_free_actions": [],

"actions": [{

"account": "eosio.token",

"name": "transfer",

"authorization": [{

"actor": actor,

"permission": "active"

}],

"data": data

}],

"transaction_extensions": [],

"expiration": ser.timePointSecToDate(ser.dateToTimePointSec(block.timestamp) + expireSeconds),

"ref_block_num": block.block_num & 0xffff,

"ref_block_prefix": block.ref_block_prefix

};

let signTransaction = await sign_transaction(transactions, ["EOS61VncKc7P8MhKzz8K7s3kAeNxFsp5ZQGoVFbLjRh1NVR1B6D9Z"], chain_id);

if (signTransaction != null && signTransaction.signatures != null) {

var transaction_detail = await push_transaction(transactions, signTransaction.signatures);

console.log('push_transaction=transaction_id==' + transaction_detail.transaction_id);

}

}

}

}

} catch (e) {

console.log(e)

}

}
