1、封裝服務(wù)類

<?phpnamespace app\common\service; use EasyWeChat\Factory; use EasyWeChat\MiniProgram\Application; use think\Hook;/*** 微信服務(wù)* @package app\common\service*/ class WeChatService {//微信公眾號配置private $officeConfig = ['app_id' => 'wx727ac3b3f4439a25','secret' => '23471aaeb7d0ab3679da9f9a7d58bb25',// 指定 API 調(diào)用返回結(jié)果的類型：array(default)/collection/object/raw/自定義類名'response_type' => 'array',//...];//微信支付private $payConfig = [// 必要配置'app_id' => 'xxxx','mch_id' => 'your-mch-id','key' => 'key-for-signature', // API 密鑰// 如需使用敏感接口（如退款、發(fā)送紅包等）需要配置 API 證書路徑(登錄商戶平臺下載 API 證書)'cert_path' => 'path/to/your/cert.pem', // XXX: 絕對路徑！！！！'key_path' => 'path/to/your/key', // XXX: 絕對路徑！！！！'notify_url' => '默認的訂單回調(diào)地址', // 你也可以在下單時單獨設(shè)置來想覆蓋它];//微信小程序配置private $miniConfig = ['app_id' => 'wx3cf0f39249eb0exx','secret' => 'f1c242f4f28f735d4687abb469072axx',// 下面為可選項// 指定 API 調(diào)用返回結(jié)果的類型：array(default)/collection/object/raw/自定義類名'response_type' => 'array','log' => ['level' => 'debug','file' => PUBLIC_PATH .

'/';if (!file_exists($dir)) mkdir($dir, 0777, true);$url = PUBLIC_PATH . $dir . 'app_mini_code.png';$response->save($url);//保存到OSS$urlOss = Hook::listen("upload_oss", $url, null, true);//刪除本地圖片和文件夾if (file_exists($url)) {unlink($url);rmdir($dir);}}return $urlOss ?? false;}}

其中微信小程序、公眾號、微信支付和開放平臺等配置都在這里面寫，如果需要企業(yè)微信等配置自行根據(jù)自己的業(yè)務(wù)修改里面的代碼即可。

3、調(diào)用服務(wù)類

• 我們只要 new 一個服務(wù)類就可以使用里面的方法了

public function createWeChatCode() {$code = (new WeChatService)->createCode();$this->success('生成小程序碼成功', $code); }

• 調(diào)用 EasyWeChat 包的方法，只需要 connect 一下就可以了，其中需要傳參

$app = (new WeChatService())->connect(1);
