整理了一下用 js-sdk 创建新用户的最简单的 Demo 实现代码。
import {PrivateKey, key, FetchChain, TransactionBuilder} from 'bitsharesjs';
import {Apis, ChainConfig} from 'bitsharesjs-ws';
generateKeyFromPassword(accountName, role, password) {
const seed = accountName + role + password;
const privKey = PrivateKey.fromSeed(seed);
const pubKey = privKey.toPublicKey().toString();
return {privKey, pubKey};
}
registerUser(username, password, registrar, referrer) {
const privKey = '这里是用来签名数据的用户active私钥';
const pKey = PrivateKey.fromWif(this.privKey);
const referrerPercent = 0;
const {pubKey: ownerPubkey} = generateKeyFromPassword(
username,
'owner',
password
);
const {pubKey: activePubkey} = generateKeyFromPassword(
username,
'active',
password
);
const {pubKey: memoPubkey} = generateKeyFromPassword(
username,
'memo',
password
);
try {
return Promise.all([
FetchChain("getAccount", registrar),
FetchChain("getAccount", referrer)
]).then((res) => {
const [chainRegistrar, chainReferrer] = res;
const tr = new TransactionBuilder();
tr.add_type_operation("account_create", {
fee: {
amount: 0,
asset_id: 0
},
registrar: chainRegistrar.get("id"),
referrer: chainReferrer.get("id"),
referrer_percent: referrerPercent,
name: username,
owner: {
weight_threshold: 1,
account_auths: [],
key_auths: [[ownerPubkey, 1]],
address_auths: []
},
active: {
weight_threshold: 1,
account_auths: [],
key_auths: [[activePubkey, 1]],
address_auths: []
},
options: {
memo_key: memoPubkey,
voting_account: "1.2.1",
num_witness: 0,
num_committee: 0,
votes: []
}
});
return tr.set_required_fees().then(() => {
tr.add_signer(pKey);
console.log("serialized transaction:", tr.serialize());
tr.broadcast();
return true;
});
}).catch((err) => {
console.log('err:', err);
});
} catch(e) {
console.log('unexpected_error:', e);
}
}
registerUser('新用户名', '新用户的密码', '用来签名的用户的用户名', '推荐用户的用户名')；
registerUser函数参数中的registrar是用来签发数据的用户的用户名，函数里面的privKey是registrar的active私钥referrerPercent是分成比例，这里注意是基于手续费的 50% 再分成。也就是referrerPercent设置为10000，则代表registrar分成 0%，referrer分成 50%。- 提交的数据中的
voting_account是设置投票代理人是谁。
