sdk接入

本文主要以nodejs sdk的方式接入，nodejs参考文档：https://github.com/dfinity/rosetta-client

生成地址，公钥私钥

let { randomBytes } = require("crypto");
const mnemonicToKeyPair = require('mnemonic-to-key-pair')
const tweetnacl = require('tweetnacl');

let { 
    key_new, 
    key_to_pub_key, 
    seed_from_pem,
    pub_key_to_address,
} = require("@dfinity/rosetta-client");

// 从用户指定的 32 字节随机数种子生成一个 ED25519 私钥。
let seed = randomBytes(32);

// 生成私钥 公钥 地址
let privateKey = key_new(seed);
let publicKey = key_to_pub_key(privateKey);
let address = pub_key_to_address(publicKey);

另外一种私钥生成和管理方式，通过助记词来生成

const {privateKey, publicKey} = mnemonicToKeyPair(
    'maze birth my runway you pulp vast universe era panda hello access',
    "m/44'/0'/0'/0/0",  // 改变这里的值，映射多个公私钥管理
    "12345671",
);
let key = tweetnacl.sign.keyPair.fromSeed(privateKey);
let priKey = key.secretKey;
let pubKey = key_to_pub_key(priKey);
let address = pub_key_to_address(publicKey);

签名认证上链

let { Session, transfer_combine, address_from_hex} = require("@dfinity/rosetta-client");
let session = new Session({baseUrl: "https://rosetta-api.internetcomputer.org"});

// 由上面生成了相应地址和公私钥(由上面的助记词随机生成的)
let priKey = "1e7f57d002109581348519cd7b2478edf1c99703ca2ae0d35be1724ae7241c9f2280216b8b286290bfffe841a7e19c846867504a522d49f1dbcdb6c29f37649c";
let pubKey = "2280216b8b286290bfffe841a7e19c846867504a522d49f1dbcdb6c29f37649c";
let address= "210b3e285f05ae41c8b5a94952ba01f5e551ab6aab9f3d6e6ec1273a";

// 打包交易
let payloadsResult = await session.transfer_pre_combine(
    Buffer.from(pubKey), // 源地址
    address_from_hex(address), // 目的地址
    BigInt(10000),  // amount decimals=9
);

// 签名，可以离线处理
let combineResult = transfer_combine(Buffer.from(priKey), payloadsResult);

// 上链发布
let sumbitResult = await session.transfer_post_combine(combineResult);
