如何在 laravel 5.8 中将变量传递给路由？

Question

路线/web.php

$urls = \App\Myurls::all();

foreach($urls as $url){

  Route::get($url->en,  function() {

    session(['lang'=> 'en']);

    return view( 'en.'.$url->view );

  });

}

错误：未定义的变量：url（在返回 view()行中）

如何将$url变量传递给 Route::get 函数？

Answer 1

你必须使用function() use ($url)$urls = \App\Myurls::all();foreach($urls as $url){  Route::get($url->en,  function() use ($url) {    session(['lang'=> 'en']);    return view( 'en.'.$url->view );  });}

Answer 2

您需要闭包中use的变量：Route::get($url->en,  function() use ($url) {  session(['lang'=> 'en']);  return view( 'en.'.$url->view );});
