Laravel - 如何访问和操作 JSON 数组元素答案

【问题描述】：

有人可以教我如何访问数据数组中的每个类别元素吗？ PS：我使用 Postman 发布这个 JSON，并尝试在 laravel 项目控制器方法中对其进行操作。

但我不断收到此错误：

ErrorException: Trying to get property &#039;data&#039; of non-object

我的路线没有问题，因为我已成功使用 get 和 post 请求进行其他简单过程。

我还使用带有 application/json 标头的 Content-Type 来使用 Postman 软件发送此 JSON。

我的控制器方法：

public function requestStore(Request $request) {

        //
}

JSON：

【解决方案1】：

假设您像这样通过 Postman 发布原始 json 不要忘记将类型设置为 JSON

像访问数组一样访问数据

Route::post('/test', function () {
    $data = request()->all();
    foreach ($data['likes']['data'] as $key => $value) {
        dd($value['category']);
    }
});

结果：

希望对你有帮助

如果它解决了您的问题，请考虑接受答案
老兄，我可以通过循环将每个数据插入db吗？？
当然，只需调用模型并将数据传递给 create 方法，但这是一个不同的问题
@CaddyDDZ 你能邀请我到房间里吗？或者我可以在某个地方联系你吗？我想问那个特定的问题:))
