nodejs开发EOS转账服务的两种方案分别是什么

本篇文章为大家展示了nodejs开发EOS转账服务的两种方案分别是什么，内容简明扼要并且容易理解，绝对能使你眼前一亮，通过这篇文章的详细介绍希望你能有所收获。

第一种，使用eosjs开发，适用于用户输入私钥方式，不安全，易造成私钥泄露。

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 }); //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); };

第二种，使用nodeos api+wallet api开发，适合用于公共账户给不同用户转账。相当于用wallet钱包服务来做密钥管理，隐藏了私钥，代码中只需提供公钥和钱包服务地址即可。

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, ["EOS61VncKc7P8MhKzz8K7s3kAeNxFsp5ZQGoVFbLjRh2NVR1B6D9Z"], 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)        }}
