SMS verification code and mobile phone verification implementation in PHP and mini program

SMS verification code and mobile phone verification implementation of PHP and mini program

With the popularity of smart phones, more and more applications need to implement mobile phone verification functions. Mobile phone verification is a way to verify a user's identity through a mobile phone number. It is often used for sending and verifying SMS verification codes. In this article, we will introduce how to use PHP and applet to implement mobile phone verification function, and provide some sample code.

1. Obtain SMS verification code

First of all, we need a service provider that can send SMS. In China, common SMS service providers include Alibaba Cloud SMS, Tencent Cloud SMS, etc. You need to register an account with these service providers and obtain the corresponding API interface.

Taking Alibaba Cloud SMS as an example, we can use its SDK to send SMS messages. First, we need to create an SMS template in the Alibaba Cloud SMS backend, and then obtain the corresponding AccessKey and SecretKey.

The following is a sample code that uses Alibaba Cloud SMS SDK to send SMS verification codes:

<?php
require_once 'aliyun-php-sdk-core/Config.php';  // 引入阿里云SDK

// 配置短信模板、AccessKey和SecretKey
$templateCode = 'SMS_123456789';
$accessKeyId = 'your_access_key_id';
$accessSecret = 'your_access_secret';

// 创建DefaultAcsClient实例
$profile = DefaultProfile::getProfile('cn-hangzhou', $accessKeyId, $accessSecret);
$acsClient = new DefaultAcsClient($profile);

// 发送短信
function sendSms($phoneNumber) {
    global $acsClient, $templateCode;
    $request = new SingleSendSmsRequest();
    $request->setSignName('your_sign_name');
    $request->setTemplateCode($templateCode);
    $request->setRecNum($phoneNumber);
    $request->setParamString('{"code":"123456"}');  // 假设验证码为123456
    $acsResponse = $acsClient->getAcsResponse($request);
    // 处理发送结果
    if ($acsResponse->Code === 'OK') {
        echo '短信发送成功';
    } else {
        echo '短信发送失败';
    }
}

// 使用示例
sendSms('13888888888');  // 向手机号码为13888888888的用户发送短信验证码
?>

2. Obtain the mobile phone verification code on the mini program

In the mini program, we You can obtain the user's mobile phone number by registering for the login interface provided by WeChat.

WXML code:

<button bindgetphonenumber="getPhoneNumber">获取手机号码</button>

Mini program JS code:

// 获取手机号码
getPhoneNumber: function(e) {
  var that = this;
  wx.login({
    success: function(res) {
      // 获取临时登录凭证code
      var code = res.code;
      wx.request({
        url: 'https://your_php_server/getPhoneNumber.php',
        method: 'POST',
        data: {
          code: code,
          iv: e.detail.iv,
          encryptedData: e.detail.encryptedData
        },
        success: function(res) {
          console.log(res.data.phoneNumber);  // 手机号码
          // 调用发送短信接口
          wx.request({
            url: 'https://your_php_server/sendSms.php',
            method: 'POST',
            data: {
              phoneNumber: res.data.phoneNumber
            },
            success: function(res) {
              console.log(res.data);  // 处理短信发送结果
            }
          });
        }
      });
    }
  });
}

3. PHP side verification SMS verification code

Finally, we need to verify the SMS verification code on the PHP side SMS verification code for verification. First, we need to save the user's mobile phone number and verification code in the database. When the user submits the SMS verification code, we can query the database to determine whether the verification code is correct.

The following is a sample code to verify the SMS verification code:

<?php
// 验证短信验证码
function verifySmsCode($phoneNumber, $code) {
    // 在数据库中查询手机号码和验证码是否匹配
    if ($code === '123456') {
        echo '验证码正确';
    } else {
        echo '验证码错误';
    }
}

// 使用示例
verifySmsCode('13888888888', '123456');  // 验证手机号码为13888888888的用户输入的验证码是否正确
?>

Summary:

Through the above steps, we can use PHP and mini programs to send SMS verification codes and verification functions. Note that in actual applications, we need to further improve the code according to specific needs and business logic, and ensure the security and correctness of data.

The above are just simple examples. Actual applications may involve more business scenarios and need to be expanded and modified according to specific circumstances. I hope this article can provide you with some reference and help you implement the mobile phone verification function.
