安装多应用模式部署

安装多应用模块扩展：think-multi-app，

composer require topthink/think-multi-app

特别注意：安装的时候一定要是在项目的根目录下安装，不然安装了以后也是用不了报单应用（app\controller\index不存在）的问题,

如果出现“Content-Length mismatch, received xxxx bytes out of the expected xxxx”错误，则需要更换composer镜像即可，使用以下命令

composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/然后在安装think-multi-app

视图安装：composer require topthink/think-view
