//routs.php
Route::get('/about',function(){
$first = 'hello';
return view('about')->with('a',$first);
});

//about.blade.php
{{ $a }}

//routs.php
Route::get('/about',function(){
$data = array(
'a' => 'O',
'b' => 'K'
);
return view('about',$data);
});

{{ $a }}
{{ $b }}

//routs.php
Route::get('/about',function(){
$first = 'hello';
$last = 'world';
//参数名称要对应
return view('about',compact('first','last'));
});

//about.blade.php
{{ $first }}
{{ $last }}
