自动生成百度小程序sitemap.txt文件路径

因为业务需要，需要在目前项目上开发一个百度小程序，百度智能小程序上线了，但是内容每天得推送，不可能一个小程序路径一个推送吧，因为小程序路径和项目路径不一致。

因为项目是用ThinkPHP开发的，在此附上自动输出sitemap.txt代码

<?php

use think\Request;
use think\Response;
use mip\Mip;

            $this->assign('mipTitle',$this->domainSettingsInfo['diySiteName']);
        } else {
            $this->assign('mipTitle',$this->mipInfo['siteName'].$this->mipInfo['indexTitle']);
        }

        return $this->mipView('index/index');
    }
