Type error: Argument 1 passed to Illuminate\Database\Eloquent\Builder::create() must be of the type array, null given

Question

我正在尝试 post laravel 中的标题和文章 api 我收到此错误

Type error: Argument 1 passed to Illuminate\Database\Eloquent\Builder::create() must be of the type array, null given, called in C:\xampp\htdocs\LaravelProject\cpapi\vendor\laravel\framework\src\Illuminate\Database\Eloquent\Model.php on line 1440

这是我的 route/api.php 文件post 文章数据

Route::post('articles', 'ArticleController@store');

Route::post('articles', function(Request $request) {
   return Article::create($request->all);
});

以及ArticleController.php文件的这个存储函数

 public function store(Request $request)
    {
        $article = Article::create($request->all());

        return response()->json($article, 201);
    }

这是文章模型class

class Article extends Model
{
    //new
    protected $fillable = ['title', 'body'];
}

我尝试在 articlecontroller 文件中更改它，但出现相同的错误

$article = Article::create($request->only([
            'title',
            'body']));

我该如何解决这个问题？

Answer 1

按照#Masivuye_Cokile的建议，我修改了路由和控制器函数中的代码，它解决了我的问题。

Route/api.php

Route::post('articles', function(Request $request) {
    $data = $request->all();
        return Article::create([
            'title' => $data['title'],
            'body' => $data['body'],
        ]);
});

在控制器函数中

 public function store(Request $request)
    {
       $article = Article::save();
       return response()->json($article, 201);
    }

Answer 2

我知道已经有一个可接受的答案，但我认为没有清楚地解释错误的原因。

如果您查看下面的代码，您会发现您键入的第二个路由定义存在错误； $request->all 而不是 $request->all()

Route::post('articles', 'ArticleController@store');

Route::post('articles', function(Request $request) {
   return Article::create($request->all);
});

所以，我认为更简单的解决方案是：

Route::post('articles', 'ArticleController@store');

Route::post('articles', function(Request $request) {
   return Article::create($request->all());
});
