实例化 eosjs
测试环境 || 开发环境
Param
keyProvider: '5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3'
Example
eos = Eos({
//私钥
keyProvider: '5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3'
});
发送交易 transfer()
Param
{
"from": "account_name", //发件人
"to": "account_name", //收件人
"quantity": "asset", //资产
"memo": "string"
}
可选参数(after Param)
options = {
authorization: 'tokyohotcoin@active', //签名交易用到的权限
broadcast: true, //是否广播交易
sign: true //是否签名交易
}
Example
1)公链令牌(EOS)转账
- 方式1
eos.transfer('tokyohotcoin', 'jailebihaido', '1.0000 EOS', '', options)
- 方式2
eos.transaction(
{
actions: [
{
account: 'eosio.token',
name: 'transfer',
authorization: [{
actor: 'tokyohotcoin', //发件人
permission: 'active'
}],
data: {
from: 'tokyohotcoin', //发件人
to: 'jailebihaido', //收件人
quantity: '7.0000 EOS', //发送资产
memo: ''
}
}
]
}
// options -- example: {broadcast: false} 自定义options
)
- 普通合约令牌(代币)转账
// 'myaccount' 创建合约代币(令牌的账户)
const myaccount = eos.contract('tokyohotcoin')
// 发送合约令牌
// 'test12344444'账户的私钥: \
5KBWYsYudu9APDdUrHVPPDdyVMhjrRVq3zqDAEzhuogDR3caApb
myaccount.transfer('jailebihaido', 'test12344444', '1.000 THC', '')
查询账户余额 getCurrencyBalance()
Param
{
"code": "name", //合约账户
"account": "name", //被查询余额的账户
"symbol": "optional
}
Example
- 查询公链代币EOS余额
eos.getCurrencyBalance('eosio.token','test12344444','EOS').then(EOSbalance => console.loge(EOSbalance))
- 查询合约代币余额
eos.getCurrencyBalance('tokyohotcoin','test12344444','THC').then(SYSbalance => console.loge(SYSbalance))
生成地址私钥 ecc.seedPrivate
1)
Param
Text : string(字符串)
Example
//根据种子生成私钥
const wif= eos.ecc.seedPrivate('zhongzi');
//根据私钥获取公钥地址
const pubkey = eos.ecc.privateToPublic(wif);
2) BIP39 根据bip39生成助记词然后生成私钥
//生成助记词
var mnemonic = BIP39.generateMnemonic();
//根据助记词生成种子
var seed = BIP39.mnemonicToSeed(mnemonic).toString(‘hex’);
//根据种子生成私钥
Var privatekey = eos.ecc.seedPrivate(seed )
创建账户 newaccount
Param
{
"creator": "account_name",
"name": "account_name",
"owner": "authority",
"active": "authority"
}
Example:
wif = '5KQwrPbwdL6PhXujxW37FSSQZ1JiwsST4cqQzDeyXtP79zkvFD3'
pubkey = 'EOS6MRyAjQq8ud7hVNYcfnVPJqcVpscN5So8BhtHuGYqET5GDW5CV'
eos.transaction(tr => {
tr.newaccount({
creator: 'tokyohotcoin', //创建者
name: 'newaccountnm',//被创建的账户名
owner: pubkey,
active: pubkey
})
tr.buyrambytes({
payer: 'tokyohotcoin', //支付创建账号花费的账户
receiver: 'newaccountnm', 被创建的账户名
bytes: 3072
})
//可选
tr.delegatebw({
from: 'tokyohotcoin',
receiver: 'newaccountnm',
stake_net_quantity: '0.0010 EOS',
stake_cpu_quantity: '0.0100 EOS',
transfer: 0
})
})
买卖内存 buyram || sellram
1)买入
Param
{
"payer": "",
"receiver": "",
"quant": "0.0001 EOS"
}
Example
>eos.buyram('tokyohotcoin','tokyohotcoin','1.0000 EOS');
2)卖出
Param
{
"account": "",
"bytes": "1" //单位bytes
}
Example

Param
{
"from": "account_name",
"receiver": "account_name",
"stake_net_quantity": "asset",
"stake_cpu_quantity": "asset",
