Question

我正在尝试探索以太坊，并创建一个允许用户签名消息并验证消息的应用程序。我为此使用web3swift框架，到目前为止，我尝试过的操作如下-

    let web3Rinkeby = Web3.InfuraRinkebyWeb3()
    let msgStr = "This is my first Ethereum App";
    let data = msgStr.data(using: .utf8)
    let signMsg = web3Rinkeby.wallet.signPersonalMessage(data!, account: address);

    print(signMsg);

但是我不确定这是否正确以及如何验证任何消息。请帮忙。

似乎您未指定确切地址。这是一个示例：

let web3Rinkeby = Web3.InfuraRinkebyWeb3()

/// 
    let keystore = try! EthereumKeystoreV3(password: "")
    let keystoreManager = KeystoreManager([keystore!])
    web3Rinkeby.addKeystoreManager(keystoreManager)
    let address = keystoreManager.addresses![0]
///

let msgStr = "This is my first Ethereum App";
let data = msgStr.data(using: .utf8)
let signMsg = web3Rinkeby.wallet.signPersonalMessage(data!, account: address);

print(signMsg);

下面是一个示例，说明如何在tests of the project中签署交易：

使用用户的私钥对任何消息签名，然后在以太坊上验证签名
