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;
}
/**

* signature (string | Buffer) buffer or hex string
* data (string | Buffer)

ecc.verify(signature, data, pubkey) === true
