1.在public下建2个入口文件，分别是

admin.php     代表后台

index.php     代表前台

2.在route文件下，分别建前后台的路由文件

admin/app.php

<?phpuse think\facade\Route;Route::get('admin/', 'index/index');Route::get('admin/weclome', 'index/weclome')->name('weclome');

index/route.php

<?phpuse think\facade\Route;Route::get('', 'index/index');Route::get('hello', 'index/hello');

3.public 目录下的.htaccess文件里如下图这样写

<IfModule mod_rewrite.c>Options +FollowSymlinks -MultiviewsRewriteEngine OnRewriteCond %{REQUEST_FILENAME} !-dRewriteCond %{REQUEST_FILENAME} !-fRewriteRule ^admin(.*)$ admin.php [L,E=PATH_INFO:$1]RewriteRule !^index(.*)$ index.php/index/ [L,E=PATH_INFO:$1]</IfModule>

到这里多入口应用入口文件就隐藏了，试试吧
