問題表現：后臺下載小程序碼失敗

處理方案：

1.打開文件app/controller/admin/v1/wechat/RoutineTemplate.php

2.找到方法getDownloadInfo

修改為圖中紅圈里的代碼

getDownloadInfo方法完整代碼

public function getDownloadInfo()
    {
        $data['routine_name'] = sys_config('routine_name', '');
        $appid = sys_config('routine_appId', '');
        if (!$appid) {
            return $this->fail('請先在設置->系統(tǒng)設置->應用設置，配置小程序相關信息');
        }
        $name = $data['routine_name'] . '.jpg';
		/** @var QrcodeServices $qrcode */
		$qrcode = app()->make(QrcodeServices::class);
		$resForever = $qrcode->qrCodeForever(0, 'code');
		$id = (int)$resForever['id'];
		/** @var QrcodeServices $QrcodeService */
		$QrcodeService = app()->make(QrcodeServices::class);
		//生成小程序地址
		$urlCode = $QrcodeService->getRoutineQrcodePath($id, 0, -1, $name);
		if ($urlCode) {
			$qrcode->update($id, ['status' => 1, 'time' => time(), 'qrcode_url' => $urlCode]);
		}
		$data['code'] = $urlCode;
        $data['appId'] = $appid;
        $data['help'] = 'https://doc.crmeb.com/web/pro/crmebprov2/1192';
        return $this->success($data);
    }
