laravel如何从输入中获取JSON值

Question

我有一个值设置为 json 的输入项，因为我想稍后在控制器中获取这个值，但我只是得到 [object, object]

JSON 是：

    [{
    "title": "G30 BMW 530d is Victoria Police's new patrol car - 80 units to join fleet by end-2018, all with 'police pack'",
    "url": "https://paultan.org/2017/09/20/g30-bmw-530d-is-victoria-police-new-patrol-car/",
    "thumbnail": "https://s1.paultan.org/image/2017/09/VP_HWP_Bmw_530D_Front_side.jpg",
    "source": "Paul Tan's Automotive News",
    "source_url": "https://paultan.org/2017/09/20/g30-bmw-530d-is-victoria-police-new-patrol-car/",
    "date_published": "2017-09-20",
    "provider": "Event Registry",
    "provider_url": "http://eventregistry.org"
}, {
    "title": "Opel Astra GSi Spied Nearly Naked",
    "url": "http://gmauthority.com/blog/2017/09/opel-astra-gsi-spied-nearly-naked/",
    "thumbnail": "http://gmauthority.com/blog/wp-content/uploads/2017/07/Opel-GSi-Teaser-1024x771.jpg",
    "source": "GM Authority",
    "source_url": "http://gmauthority.com/blog/2017/09/opel-astra-gsi-spied-nearly-naked/",
    "date_published": "2017-09-19",
    "provider": "Event Registry",
    "provider_url": "http://eventregistry.org"
}]

Vuejs

<div v-for="article in articles_sortByDate" v-bind:key="article.id">
    <input type="checkbox"
          :value="article" 
           v-model="checkedArtcles"  
           name='checkedArtcles'>
</div>

现在，如果我尝试使用

从控制器获取此值

dd($request->input('checkedArtcles'));

//this results in [Object, object]

也试过了：

dd(json_decode($request->input('checkedArtcles')));

//this return NUll

Answer 1

如果你不想要一个对象，解码字符串，但是添加true给你一个关联数组：

$array = json_decode($string, true);

Answer 2

在您的 javascript 逻辑中（在本例中为 vue）将您的 json 解析为字符串，然后附加到 select 的值，然后在控制器中您可以尝试访问 $request->input('checkedArtcles') 或 dd。
