Using EasyWeChat and PHP to develop the SMS verification code function of WeChat mini programs

With the popularity of WeChat mini programs, many developers have begun to pay attention to how to implement the SMS verification code function in WeChat mini programs. In this article, we will introduce how to use EasyWeChat and PHP to develop the SMS verification code function of the WeChat applet, and provide code examples to help you quickly implement this function.

1. Preparation

Before we start, we need to register a small program on the WeChat open platform and obtain the corresponding AppID and AppSecret. At the same time, we also need to download and install Composer, and introduce the EasyWeChat package into the project.

2. Installation and configuration of EasyWeChat

First, open a command line window in the project directory and run the following command to install the EasyWeChat package:

composer require overtrue/wechat

Installation completed Finally, we need to introduce EasyWeChat's automatic loading file into the project, open the project's entry file (usually index.php), and add the following code:

require_once 'vendor/autoload.php';

Next, we need to create an EasyWeChat instance and perform Corresponding configuration. Open the index.php file and add the following code:

use EasyWeChatFactory;

$config = [
    'app_id' => 'your-app-id',
    'secret' => 'your-app-secret',
    'token' => 'your-token',
];
$app = Factory::miniProgram($config);

Replace "your-app-id" in the above code with the AppID of your mini program, and replace "your-app-secret" with your mini program AppSecret of the program and replace "your-token" with the Token you set.

3. Configure SMS verification code template

To implement the SMS verification code function in the WeChat applet, we first need to register on the WeChat public platform and configure an SMS verification code template. The specific steps are as follows:

• Log in to the WeChat public platform and find "Development-WeChat SMS-SMS Template".
• Click "Create SMS Template" and fill in the template name, template content and other information as required.
• After submitting for review, wait for the review to pass. After passing the review, you will get a template ID.

4. Send SMS verification code

After obtaining the SMS verification code template ID, we can use the interface provided by EasyWeChat to send the SMS verification code. The following is a sample code:

$app->template_message->send([
    'touser' => 'openid',
    'template_id' => 'your-template-id',
    'page' => 'pages/index/index',
    'data' => [
        'code' => '123456',
        'time' => '5分钟',
    ],
]);

Replace "openid" in the above code with the OpenID of the user who receives the SMS verification code, and replace "your-template-id" with the ID of the SMS verification code template. In the "data" array, we can customize some variables that need to be replaced in the template, such as "code" indicating the verification code, and "time" indicating the validity time of the verification code.

5. Verify SMS verification code

After the user enters the SMS verification code, we also need to verify the verification code. The following is a sample code:

$validCode = '123456'; // 用户输入的短信验证码
$storedCode = '123456'; // 存储在后台的短信验证码

if ($validCode == $storedCode) {
    // 验证通过，执行相应的逻辑
} else {
    // 验证失败，给出相应的提示
}

Replace "validCode" in the above code with the SMS verification code entered by the user, and replace "storedCode" with the SMS verification code stored in the background. By comparing whether the two are equal, we can determine whether the verification code is valid.

Summary

By using EasyWeChat and PHP, we can implement the SMS verification code function in the WeChat applet. In this article, we introduce how to use EasyWeChat to send SMS verification codes and provide corresponding code examples. I hope this article will be helpful to you in developing the SMS verification code function of WeChat applet. If you have any questions, please feel free to leave a message.
