PHP method to implement WeChat applet message push

With the popularity of WeChat mini programs, more and more companies and individuals are beginning to use WeChat mini programs to showcase their products and services. They also need to push messages to users to improve user experience and retention rates. This article will introduce how to use PHP to implement WeChat mini program message push, helping developers better develop and manage mini programs.

1. Obtain the APPID and APPSECRET of the WeChat applet

Before pushing the WeChat applet message, we need to obtain the APPID and APPSECRET of the applet. These two parameters can be found in WeChat public Get it from the platform. The specific acquisition method is as follows:

1. Log in to the WeChat public platform and enter the mini program management background.
2. Click the "Develop" option in the left navigation bar to enter the "Development Settings" page.
3. In the "Development Settings" page, you can see the APPID and APPSECRET of the mini program.

2. Use PHP SDK to build a mini program message push system

After obtaining the APPID and APPSECRET of the mini program, we can use the officially provided SDK in the PHP environment. Build a small program message push system. Here we use EasyWeChat SDK for development. The specific usage method is as follows:

1. Install EasyWeChat SDK

First you need to install EasyWeChat SDK in the PHP environment. You can use composer to install it. , the installation command is as follows:

composer require "overtrue/wechat:^5.0"

2. Configure EasyWeChat SDK

After installing EasyWeChat SDK, you need to configure the APPID and APPSECRET of the applet in the code, and which applet to use Program message push method. You can add the following configuration in the code:

use EasyWeChatFactory; $config = [ 'app_id' => 'your-app-id', 'secret' => 'your-app-secret', 'response_type' => 'array', // 这里设置将响应结果转化为数组 ... ]; $app = Factory::miniProgram($config);

Among them,app_idandsecretrepresent the APPID and APPSECRET of the mini program respectively, andresponse_typerepresents the The response result is converted into an array to facilitate subsequent code processing.

3. Implementing Mini Program Message Push

After configuring EasyWeChat SDK, you can start to implement the code for Mini Program message push. Here are two commonly used message push methods: template messages and customer service messages.

(1) Template message

Template messages are usually used in message push scenarios that require fixed formats, such as order notifications, event promotions, etc. You can add template messages in the mini program management background, and then push the messages through the API. The specific implementation code is as follows:

$templateId = 'your-template-id'; // 模板消息ID，需要在小程序管理后台中进行添加 $toUser = 'open-id'; // 接收消息的用户openID $page = 'index'; // 点击模板消息后跳转的页面 $formId = 'form-id'; // 表单ID，通过调用 wx.chooseAddress 等 API 获取 $data = [ // 模板消息中需要显示的内容 'keyword1' => ['value' => 'value1', 'color' => '#173177'], 'keyword2' => ['value' => 'value2', 'color' => '#173177'], ... ]; $result = $app->template_message->send([ 'touser' => $toUser, 'template_id' => $templateId, 'page' => $page, 'form_id' => $formId, 'data' => $data, ]);

(2) Customer service messages

The format of customer service messages is relatively flexible. You can send messages directly in scenarios where push messages are needed, such as user questions, customer service answers, etc. The specific implementation code is as follows:

$toUser = 'open-id'; // 接收消息的用户openID $message = new Text(['content' => 'Hello World!']); // 客服消息中需要显示的内容 $result = $app->customer_service->message($message)->to($toUser)->send();

3. Conclusion

Through the introduction of this article, we have learned how to use PHP SDK to implement message push of WeChat applet, which mainly includes obtaining the APPID of the applet and APPSECRET, use EasyWeChat SDK to build a mini program message push system, and implement two methods of mini program message push: template messages and customer service messages. Through these methods, we can provide better service experience for mini program users and improve user retention rate.
