thinkphp开发小程序的代码

以下是使用 ThinkPHP 开发小程序的示例代码：

1. 创建小程序控制器

namespace app\wxapp\controller;

use think\Controller;

class Index extends Controller
{
    public function index()
    {
        return 'Hello, World!';
    }
}

2. 创建小程序路由

use think\Route;

Route::get('/', 'wxapp/Index/index');

3. 配置小程序请求处理

use think\Response;

$http = (new \think\Request())->scheme();
$config = \think\facade\Config::get('wxapp.');
if ($http == 'https' && $config['https_cert'] && $config['https_key']) {
    $cert = \think\facade\Request::instance()->server('SSL_CERT');
    $key = \think\facade\Request::instance()->server('SSL_KEY');
    if (!$cert || !$key) {
        $response = Response::create('Invalid request', 'text/plain');
        $response->code(403);
        $response->send();
        exit;
    }
    file_put_contents($config['https_cert'], $cert);
    file_put_contents($config['https_key'], $key);
}

$server = new \app\wxapp\lib\WxappServer();
$server->serve();

4. 创建小程序服务类

namespace app\wxapp\lib;

use EasyWeChat\Factory;
use EasyWeChat\Kernel\Messages\Message;
use EasyWeChat\Kernel\Messages\Text;
use think\Config;
use think\Controller;
use think\Db;
use think\facade\Cache;
use think\facade\Request;

class WxappServer extends Controller
{
    private $app;

    public function __construct()
    {
        parent::__construct();

        $config = Config::get('wxapp.');
        $this->app = Factory::miniProgram($config);
    }

    public function serve()
    {
        $response = $this->app->server->serve();
        $response->send();
    }

    public function sendTemplateMessage($touser, $template_id, $data, $page = '', $form_id = '', $emphasis_keyword = '')
    {
        $message = [
            'touser' => $touser,
            'template_id' => $template_id,
            'page' => $page,
            'form_id' => $form_id,
            'data' => $data,
            'emphasis_keyword' => $emphasis_keyword,
        ];
        $result = $this->app->template_message->send($message);
        return $result;
    }

    public function handleTextMessage(Message $message)
    {
        $content = $message->Content;
        $openid = $message->FromUserName;
        $result = $this->app->user->get($openid);
        $nickname = $result['nickname'];
        $response = new Text('Hello, ' . $nickname . '! Your message is: ' . $content);
        return $response;
    }
}

5. 处理小程序事件

use EasyWeChat\Kernel\Messages\Message;
use think\Db;
use think\facade\Cache;
use think\facade\Request;

$server->on(Message::TEXT, function ($message) use ($server) {
    return $server->handleTextMessage($message);
});

以上代码仅供参考，具体实现需要根据实际情况进行调整。
