兼容Scatter

MYKEY兼容Scatter协议,您可以直接开发兼容Scatter协议的dapp,再通过mykey内置浏览器访问。也可以参考以下链接,了解更多Scatter协议的内容:

https://get-scatter.com/developers/settingupforwebapps

登录

先使用scatter.connect方法,再使用login方法即可获得用户的账号信息。

import ScatterJS from "@scatterjs/core";

ScatterJS.connect("My DAPP", { network }).then(connected => {
  if (!connected) return alert("no scatter");

  const eos = ScatterJS.eos(network, Api, { rpc });
  this.setState({ eos });

  ScatterJS.login().then(id => {
    if (!id) return alert("no identity");
    const account = ScatterJS.account("eos");
    this.setState({ account }, this.getVote);
  });
});

验证MYKEY的签名

MYKEY的账号体系与其他的EOS账号有所差异,验证MYKEY签名时,需要使用Reserved公钥

Reserved Key的公钥,可以通过智能合约mykeymanager的表keydata查询到。查询时,指定范围为MYKEY账号,index为3。

/**
 * 获取ReservedKey
 * 详情参考 https://docs.mykey.org/v/English/dive-into-mykey/mykey-on-eos#mykey-account-structure
 * @param  {String}  name  MYKEY账号
 * @return {String}  ReservedKey/the 3rd Operation Key 
 */
async getReservedKey(name) {
	const mgrcontract = await this.getMykeyMgr(name)
    const mykey_signkey_index = 3
    const keydata = await this.eosJsonRpc.get_table_rows({json:true, code:mgrcontract, scope:name, table:'keydata', lower_bound: mykey_signkey_index, limit:1})
    if(!keydata) return '';
    return keydata.rows[0].key.pubkey;
}

/**
 * 验证已签名的数据
 * Parameters
 *  signature (string | Buffer) buffer or hex string
 *  data (string | Buffer)
 *  pubkey (pubkey | PublicKey)
 *  encoding (optional, default 'utf8')
 *  hashData boolean sha256 hash data before verify (optional, default true)
 */
ecc.verify(signature, data, pubkey) === true
