用于从 web3 已签名消息中提取地址的 Laravel 包

用法

Composer

composer require desnake/web3signature

视图

//prepare message to sign

const msgtext = {{$msg}};   //Message from backend database sent with view
const hashedMessage = Web3.utils.fromUtf8(msgtext);
console.log(hashedMessage);

//get user to sign the message

const signature = await window.web3.eth.sign(hashedMessage, accounts[0]);

//Make request to controller and verify signature in backend via API
//!!CAUTION!!
//Not much secure way to do this but only for demo purposes.

const URL = "api.myproject.com/api/v1/";
const request = URL + msgtext + "/" + signature;

window.location.href(request);

控制器

1: 创建一个 API 路由，以便将签名传递给控制器函数 2: 在控制器中导入 trait Web3ForContracts

    use DeSnake\Web3signature\Web3ForContracts;
    and Include trait into the controller class.
    `` use Web3ForContracts;``

3: 从控制器中调用 personal_ecRecover 函数

Note: $msg is plaintext string that is signed and signature is the signed message
    $msg = "Hello World";   //Message from backend database.
    $address = $this->personal_ecRecover($msg, $signature);

注意

包处于开发模式。
