Question

我在laravel中使用了此功能，效果很好，但是我想插入一个json函数以在android上使用。

这是我的第一个可以帮助我或指导我取得好成绩的人。

public function storeavis(Request $request)
{

$avis = new AvisIntervention();
$avis ->qualité =$request->input('qualité');
$avis ->nbr_heure =$request->input('nbr_heure');
$avis ->service =$request->input('service');
$avis ->note =$request->input('note');
$avis ->client_id =$request->input('client_id');
$avis ->intervention_id = $request->input('intervention_id');
$avis->save();
return redirect('avis');

}

路线

Route::post('/storeavis', 'Avis_InterventionController@storeavis');

我总是收到以下消息：

Answer 1

您可以像这样使用laravel的内置方法response()->json

public function store(Request $request)
{

    $avis = new AvisIntervention();
    $avis ->qualité =$request->input('qualité');
    $avis ->nbr_heure =$request->input('nbr_heure');
    $avis ->service =$request->input('service');
    $avis ->note =$request->input('note');
    $avis ->client_id =$request->input('client_id');
    $avis ->intervention_id = $request->input('intervention_id');
    $avis->save();

    return response()->json(['avis' => $avis]);

}

Answer 2

在JSON中，值必须是以下数据类型之一：
a string
a number
an object (JSON object)
an array
a boolean
null
JSON值不能是以下数据类型之一：
a function
a date
undefined

class Cl
{
    public $val = 5;

    public function f(){
        echo '5';
    }

    public $func;

    public function __construct()
    {
        $this->func  = function () {
            return 'func';
        };
    }

}

$cl = new Cl();
$js = json_encode($js);
$cl = json_decode($js);

print_r($cl);
//            stdClass Object
//            (
//                [val] => 5
//                [func] => stdClass Object
//            (
//            )
//            
//

如何将此存储函数转换为json
