认证
第三方应用唤起MYKEY进行认证绑定。参数请详见类定义:AuthorizeRequest 和 MYKEYWalletCallback。（为了更强的安全性，可以设置CallBackUrl进行服务端验签。）
MYKEY将签名后的数据POST到第三方应用提供的CallBackUrl，请求第三方应用服务端验证，第三方应用服务端需要从合约数据中获取该用户MYKEY账号的Reserve Key进行验签，获取方式参考 MYKEY链上数据。
第三方应用提供的CallBackUrl接口参数：
{
"protocol":"", // 协议名，使用MYKEY双向绑定方式协议为MYKEY，使用MYKEY轻量级方式协议为MYKEYSimple
"version":"", // 协议版本信息，如1.0
"dapp_key":"", // MYKEY分配的DAPP_KEY，使用MYKEY双向绑定方式时提供，由MYKEY服务端分配，从dapp客户端初始化方法传入
"uuID":"", // 用户id，MYKEY双向绑定方式此字段为dapp客户端初始化时传入的uuid；MYKEY轻量级方式此字段为用户的设备ID；
"sign":"", // eos签名, 签名数据：timestamp + account + uuID + ref
"ref":"", // 来源, mykey
"timestamp":"", // 当前UNIX时间戳, 精确到秒
"account":"", // eos账户名
"chain": "" // 值为ANY, EOS, ETH，或者不传递该参数
}
验签公式：
认证时，MYKEY会返回mykeyUID和mykeyUIDSignature字段给第三方应用。mykeyUID是用户在MYKEY的唯一标识。
ETH
EOS
// 构造未签名数据
let message = hex(timestamp + account + uuID + ref)
let unsignedData = "\x19Ethereum Signed Message:\n" + message.length + message
// 构造mykeyUID的未签名数据
let messageForMykeyUID = timestamp + account + uuID + ref + mykeyUID
let unsignedDataForMykeyUID = "\x19Ethereum Signed Message:\n" + messageForMykeyUID.length + messageForMykeyUID
// 构造未签名数据
let unsignedData = timestamp + account + uuID + ref
// 使用ReserveKey验证签名
ecc.verify(signature, unsignedData, pubkey) === true
// 构造mykeyId的未签名数据
let unsignedDataForMykeyId = timestamp + account + uuID + ref + mykeyId
// 使用ReserveKey验证mykeyId签名
ecc.verify(signature, unsignedDataForMykeyId, pubkey) === true
返回格式：
{
"account": "MYKEY账号",
"chain": "EOS", //EOS或者ETH
"dappKey": "xxxxxxxxx", //MYKEY用于 通信加密，DAPP方可忽略
"dappUserId": "xxxxxx", //MYKEY用于通信加密，DAPP方可忽略
"mykeyUID": "xxxxxxxxx", //用户在MYKEY的唯一标记符
"accountType": 1, //1：有紧急联系人的账户，2：无紧急联系人的账户
//mykeyUID的签名，为了确保mykeyUID不被篡改。签名格式为：unsignedData = timestamp + account + uuID + ref + mykeyUID
"mykeyUIDSignature": "SIG_K1_K6AnPSrBfsmoTjo9Dec4QgZPKLHenhPm1rmrsNNN5sxhoa2ERQ7jySYb1NKqG5LrafTRBDe2fAEJkD1xMWYaUQYuygJbL3",
"origin": "mykey",
"protocol": "MYKEYSimple",
"pubKey": "EOS7FDwQ3Jkxu4dCJnAMJ3Na2V4GYL9YcwGCkhCp6cvTjjtLW5ZGA", //用户的ReservedKey
//签名，签名格式为：unsignedData = timestamp + account + uuID + ref
"signature": "SIG_K1_KfD3MdkVRaShXCBvpi3ueLZwUZtUQyqyCS5V2EDhudfXxHvxvS7fSwZHo7aSs7WXLjfLezpThaEbFbk2yafUTzR53kwc2x",
"timestamp": 1585650292,
"version": "1.0"
}
调用例子：
AuthorizeRequest authorizeRequest = new AuthorizeRequest()
// chain的值可以为EOS（默认）, ETH，或者ANY。如果是“ANY”，MYKEY任选一条可用的链签名并修改chain为可用链的值(例如：ETH或EOS)，并返回给SDK接入方
.setChain(ChainCons.EOS)
.setUserName("bobbobbobbob")
// DApp CallbackUrl
// param：{"protocol": "", "version": "", "dapp_key": "", "uuID": "", "public_key": "", "sign": "", "ref": "", "timestamp": "", "account": ""}
// return: same as SimpleWallet {"code": [0-2], "message": ""}
.setCallbackUrl(Config.DAPP_CALLBACK_URL)
.setInfo("Perform the binding of dapp and MYKEY");
MYKEYSdk.getInstance().authorize(authorizeRequest, new MYKEYWalletCallback() {
@Override
public void onSuccess(String dataJson) {
// dataJson：{"protocol": "", "version": "", "dapp_key": "", "uuID": "", "public_key": "", "sign": "", "ref": "", "timestamp": "", "account": ""}
LogUtil.e(TAG, "onSuccess");
Toast.makeText(activity, "success", Toast.LENGTH_LONG).show();
// DApp此时需要去DApp server查询是否绑定成功
}
@Override
public void onError(String payloadJson) {
// payloadJson: {"errorCode":,"errorMsg":""}
LogUtil.e(TAG, "onError payloadJson:" + payloadJson);
Toast.makeText(activity, "error，payloadJson:" + payloadJson,Toast.LENGTH_LONG).show();
}
@Override
public void onCancel() {
LogUtil.e(TAG, "cancel");
Toast.makeText(activity, "cancelled", Toast.LENGTH_LONG).show();
}
});
