Use EasyWeChat and PHP to develop mobile phone functions for WeChat mini programs
With the rapid development of WeChat mini programs, more and more companies and individuals have begun to pay attention to the development of WeChat mini programs. Binding mobile phone functions is a common feature in many small programs, which can increase user stickiness and security. This article will introduce how to use EasyWeChat and PHP to develop the mobile phone binding function of WeChat applet, and provide corresponding code examples.
1. Understanding EasyWeChat
EasyWeChat is a simple and easy-to-use WeChat public account development toolkit that can easily develop WeChat public accounts and mini programs. It provides rich interfaces and convenient operation methods, allowing developers to quickly build WeChat-related applications.
2. Preparation work
Before starting development, we need to prepare some necessary work.
Install EasyWeChat, which can be installed through Composer. Composer is a PHP package management tool that can easily manage PHP dependency packages.
composer require overtrue/wechat
3. Develop the mobile phone binding function
Introduce the EasyWeChat namespace in the controller and create a WeChat instance.
use EasyWeChatFactory; $config = [ 'app_id' => 'your-app-id', 'secret' => 'your-app-secret', 'response_type' => 'array', ]; $app = Factory::miniProgram($config);
Next, we need to write an interface to obtain the user’s mobile phone number and bind it.
public function bindMobile(Request $request) { // 从请求中获取code和encryptedData以及iv $code = $request->input('code'); $encryptedData = $request->input('encryptedData'); $iv = $request->input('iv'); // 使用code换取session_key $session = $app->auth->session($code); // 解密手机号码 $decryptedData = $app->encryptor->decryptData($session['session_key'], $iv, $encryptedData); // 获取手机号码 $mobile = $decryptedData['purePhoneNumber']; // 将手机号码与用户绑定 // ... 你的代码 // 返回绑定结果 return response()->json([ 'code' => 0, 'message' => '绑定成功' ]); }
4. Mini program front-end code
In the front-end code of the mini program, we need to use wx.login to obtain the user's code, and use wx.getUserInfo to obtain encryptedData and iv. This data is then sent to the back-end interface for binding the mobile phone.
// 绑定手机 bindMobile: function() { var that = this; wx.login({ success: function(res) { if (res.code) { wx.getUserInfo({ success: function(userRes) { wx.request({ url: 'your-backend-url', method: 'POST', data: { code: res.code, encryptedData: userRes.encryptedData, iv: userRes.iv }, success: function(res) { console.log(res); } }); } }); } } }); }
5. Summary
This article introduces how to use EasyWeChat and PHP to develop the mobile phone binding function of WeChat applet. Through the interfaces and tools provided by EasyWeChat, we can easily implement the binding function of the mini program to the mobile phone. At the same time, through the cooperation of front-end and back-end, user experience and security can be improved. I hope this article will be helpful to your WeChat applet development!
