ThinkPHP6 WeChat Development Guide: Quickly Build WeChat Public Account Application

Introduction:
WeChat Public Account is an important social media platform for individuals and enterprises. It provides great opportunities in marketing and information dissemination. In this article, we will introduce how to use ThinkPHP6 to quickly build a WeChat public account application, and provide some commonly used code examples.

1. Environment preparation
   Before starting development, we first need to prepare the following environment:
2. PHP7 or above version
3. ThinkPHP6 framework
4. WeChat public account developer account
5. Create project

First, we need to create a ThinkPHP6 project locally. The creation and installation of the project can be completed through Composer:

composer create-project topthink/think=6.* myproject

3. Configuration file

In the config directory of the project, create a new The configuration file of wechat.php is used to store WeChat related configuration information. The content of the configuration file is as follows:

return [
    // 微信公众号应用ID
    'appid' => 'your_appid',
    // 微信公众号应用密钥
    'secret' => 'your_secret',
    // 微信公众号接口Token
    'token' => 'your_token',
];

4. Access verification

In order to ensure that our application can access the WeChat public account platform, we need to add it to the route of the project Create a wechat.php routing file in the directory and add the following code:

use thinkacadeRoute;

// 微信接入验证，用于接收微信服务器发送的Token验证请求
Route::rule('wechat', 'wechat/index')->ext('xml')->middleware(ppmiddlewareWechat::class);

Then, we create a new ## in the app/middleware directory ##Wechat.php middleware file and add the following code:

namespace appmiddleware;

class Wechat
{
    public function handle($request, Closure $next)
    {
        // 获取微信服务器请求参数
        $params = $request->get();

        // 验证Token
        if ($this->checkToken($params)) {
            return $next($request);
        } else {
            return 'Invalid Access!';
        }
    }

    private function checkToken($params)
    {
        // 根据自己的逻辑来验证Token
        // ...
        return true;
    }
}

Processing WeChat messages

After the access verification is passed, we can Start processing the messages sent from the WeChat official account. Create a

Wechat.php controller file in the app/controller directory, and add the following code:

namespace appcontroller;

use thinkRequest;

class Wechat
{
    public function index(Request $request)
    {
        $xmlData = file_get_contents('php://input');
        $data = $this->xmlToArray($xmlData);

        // 根据消息类型进行处理
        switch ($data['MsgType']) {
            case 'text':
                // 处理文本消息
                $result = $this->handleTextMessage($data);
                break;
            case 'event':
                // 处理事件消息
                $result = $this->handleEventMessage($data);
                break;
            // 其他消息类型和处理逻辑
            // ...
        }

        return $this->arrayToXml($result);
    }

    private function handleTextMessage($data)
    {
        // 处理文本消息的逻辑
        // ...
        return [
            'ToUserName' => $data['FromUserName'],
            'FromUserName' => $data['ToUserName'],
            'CreateTime' => time(),
            'MsgType' => 'text',
            'Content' => 'Hello, World!'
        ];
    }

    private function handleEventMessage($data)
    {
        // 处理事件消息的逻辑
        // ...
        return [
            'ToUserName' => $data['FromUserName'],
            'FromUserName' => $data['ToUserName'],
            'CreateTime' => time(),
            'MsgType' => 'text',
            'Content' => 'Welcome to our WeChat account!'
        ];
    }

    private function xmlToArray($xml)
    {
        // 将XML转换为数组的方法
        // ...
        return $data;
    }

    private function arrayToXml($data)
    {
        // 将数组转换为XML的方法
        // ...
        return $xml;
    }
}

Deploy to server

After completing the writing of the code, we can deploy the project to the server. After installing the necessary environment on the server, use the following command to start the project:

php think run --host=0.0.0.0 --port=80

Configure the public account

Finally, we need to configure the interface in the WeChat public account developer backend address. Set the interface address to the address of the server we deployed, and fill in the

token, appid, secret and other information correctly.
