## Getting Started

```

1. 安装git和yarn(比如在ubuntu中安装git: sudo apt-get install git)

2. 安装Chrome浏览器

3. Chrome浏览器安装Scatter插件

4. git clone [email protected]:LucienLau/EOS-Slots.git

5. cd EOS-Slots

6. yarn install

7. yarn start

```

## 说明

###### 安装eosjs库

`yarn add eosjs`

###### 引入eosjs库

`import EOS from 'eosjs'`

###### 初始化eosjs句柄

```

const network = {

    blockchain: 'eos',

    protocol: 'http',

    host: 'api.kylin.eosbeijing.one',

    port: 8880,

    chainId: '5fff1dae8dc8e2fc4d5b23b2c7665c97f9e9d8edf2b6485a86ba311c25639191'  // kylin net

}

this.eosjs = Eos({

    httpEndpoint: `${network.protocol}://${network.host}:${network.port}`,

    chainId: network.chainId

});

```

###### 初始化scatter句柄

```

document.addEventListener('scatterLoaded', scatterExtension => {

    this.scatter = window.scatter;

    window.scatter = null;

    if (this.scatter && this.scatter.identity) {

        const account = this.scatter.identity.accounts.find(account => account.blockchain === 'eos');

        this.setState({ player_account: account.name });

        this.setState({ is_login: true });

    }

});

```

###### 调用scatter钱包获取账号授权

```

this.scatter.getIdentity({ accounts: [network] }).then(() => {

    const account = this.scatter.identity.accounts.find(account => account.blockchain === 'eos');

    this.setState({ player_account: account.name });

    this.setState({ is_login: true });

});

```

###### 调用scatter钱包释放账号授权

```

this.scatter.forgetIdentity().then(() => {

    this.setState({ is_login: false });

    this.setState({ player_account: 'Login' });

});

```

###### 调用scatter钱包进行转账

```

// transfer '5 EOS' to 'bbbbbbbbbbbb' from 'aaaaaaaaaaaa' e.g.

const eos = this.scatter.eos(network, Eos, {});

eos.transfer({

    from: 'aaaaaaaaaaaa',

    to: 'bbbbbbbbbbbb',

    quantity: '5.0000 EOS',

    memo: 'test'

}).then(res => {

    console.log(success);

    console.log(res);

}).catch(e => {

    console.error(e);

});

```

###### 获取合约中Table的数据

```

// 比如账号aaaaaaaaaaaa部署了一份合约，合约中定义了一个叫record的表，表的code和scope都是self，则：

this.eosjs.getTableRows({

    json: true,

    code: 'aaaaaaaaaaaa',

    scope: 'aaaaaaaaaaaa',

    table: 'record',

    // lower_bound: '2',  // 获取表中主键值大于等于2的行数据

    // upper_bound: '2',  // 获取表中主键值小于2的行数据

    // limit: 20          // 只获取20行数据

}).then(res => {

    console.log(success);

    console.log(res);

}).catch(e => {

    console.error(e);

});

```

###### 获取账户资产

```

// EOS代币在eosio.token合约的accounts表中

this.eosjs.getTableRows({

    json: true,

    code: 'eosio.token',

    scope: this.state.player_account,

    table: 'accounts'

}).then(eosBalance => {

    if ( eosBalance.rows[0] ) {

        console.log('eos balance: ', eosBalance.rows[0].balance);

    }

}).catch(e => {

    console.error(e);

})

```
