双11验证码短信选购

// 生成随机验证码
function generateVerificationCode() {
    const chars = '0123456789';
    let code = '';
    for (let i = 0; i < 6; i++) {
        code += chars.charAt(Math.floor(Math.random() * chars.length));
    }
    return code;
}

// 发送验证码短信（模拟）
function sendVerificationCode(phoneNumber) {
    const code = generateVerificationCode();
    console.log(`Sending verification code ${code} to ${phoneNumber}`);
    // 实际应用中，这里应调用短信服务API发送短信
    return code;
}

// 用户输入验证码并验证
function verifyCode(inputCode, sentCode) {
    return inputCode === sentCode;
}

// 示例使用
const phoneNumber = '1234567890';
const sentCode = sendVerificationCode(phoneNumber);
// 假设用户输入了验证码
const userInputCode = '123456'; // 这里应从用户输入获取
if (verifyCode(userInputCode, sentCode)) {
    console.log('Verification successful!');
} else {
    console.log('Verification failed!');
}
