laravel默认读取的uri是$_SERVER[‘REQUEST_URI’]; 所以你可以在任何页面构建一个请求test
$uri = '/test'; $_SERVER['REQUEST_URI'] = $uri . '?' . $_SERVER['QUERY_STRING']; require __DIR__ . '/public/index.php';运行请求
$app = require_once __DIR__.'/../bootstrap/app.php'; $kernel = $app->make(Illuminate\Contracts\Http\Kernel::class); $response = $kernel->handle( $request = Illuminate\Http\Request::capture() ); $response->send(); $kernel->terminate($request, $response);bootstrap/app.php
