Teach you to use EasyWeChat and PHP to build the customer service function of WeChat mini programs

With the rapid development and popularity of WeChat mini programs, more and more companies and individuals have begun to use WeChat mini programs to promote their business. Communicate with users. The customer service function is an important part that cannot be ignored. It can help companies solve user problems and provide a better user experience. This article will teach you how to use EasyWeChat and PHP to build the customer service function of the WeChat applet, allowing you to easily build a powerful customer service system.

First of all, we need to prepare the following tools and materials:

• PHP development environment, such as XAMPP or WAMP, etc.;
• EasyWeChat library file, which can be downloaded on GitHub .

Step 1: Install and configure the EasyWeChat library file

1. Download the EasyWeChat library file to your PHP project directory, assuming the directory name is "wechat".
2. Create a new file in the "wechat" directory and name it "config.php". In this file, we need to configure parameters such as AppID and AppSecret of the WeChat applet to communicate with the WeChat server. Please register on the WeChat public platform and create a mini program to obtain these parameters and fill them in the "config.php" file.

Sample code:

<?php
return [
    'default' => [
        'app_id' => 'your-app-id',
        'secret' => 'your-app-secret',
    ],
];

Step 2: Write customer service function code

1. Create a new file in the "wechat" directory and name it " customer_service.php". In this file, we will write code for processing WeChat applet customer service messages.

Sample code:

<?php
require 'vendor/autoload.php';

$config = require 'config.php';
$app = new EasyWeChatFoundationApplication($config);

$server = $app->server;

$server->setMessageHandler(function($message) {
    // 判断收到的消息类型并作出相应处理
    switch ($message->MsgType) {
        case 'text':
            // 处理文本消息
            return handleTextMessage($message);
        case 'image':
            // 处理图片消息
            return handleImageMessage($message);
        // 添加其他类型消息的处理
        // ...
        default:
            // 处理默认类型消息
            return handleDefaultMessage($message);
    }
});

$response = $server->serve();

$response->send();

2. In the "customer_service.php" file, we define a callback function that handles messages. You can customize message processing logic according to business needs. In the following example, we define three processing functions: handleTextMessage() is used to process text messages, handleImageMessage() is used to process image messages, and handleDefaultMessage() is used to process other message types.

Sample code:

function handleTextMessage($message) {
    // 获取收到的文本消息内容
    $content = $message->Content;

    // 处理文本消息的逻辑

    return "收到了您的文本消息：" . $content;
}

function handleImageMessage($message) {
    // 获取收到的图片消息URL
    $image = $message->PicUrl;

    // 处理图片消息的逻辑

    return "收到了您的图片消息：" . $image;
}

function handleDefaultMessage($message) {
    // 处理默认消息的逻辑

    return "收到了您的消息，但暂时无法处理";
}

Step 3: Deploy and test the customer service function

1. Upload the "customer_service.php" file to your PHP server, And make sure the configuration is correct.
2. On the WeChat public platform, enter the mini program settings page, find "Development-Development Settings", and set the "Server Domain Name" to your server address.
3. Modify the mini program source code, add a customer service button or menu, and trigger a customer service session after clicking it. For example, you can add the following code to the wxml file of a certain page:

<button open-type="contact">联系客服</button>

4. Test the customer service function on the mini program, send text messages or picture messages to the mini program, and you can see the server The returned processing result.

Summary:
By using EasyWeChat and PHP, we can easily build the customer service function of the WeChat applet. You can modify and improve the sample code as needed to make the customer service system more in line with your business needs. I hope this article can help you, and I wish you a successful WeChat mini program customer service system!
