问如何在Laravel中验证用户的输入？

EN

  public function store(Request $request)
{
    $validation=$this->getValidationFactory()->make($request->all(),[
        'body'=>'required',
        'image'=>'required|mimes:jpeg,png'
    ]);

    if($validation->failed()){
        return response()->json(['message'=>'Invalid Input Data!'],400);
    }

    $article=new Article();
    $article->title=$request->title;
    $article->body=$request->body;
    $article->source=$request->source;

    if($article->save()){
        $article->categories()->sync($request->categories);

    }
    $name='article-'.$article->id.'.'.$request->file('image')->getClientOriginalExtension();
    $request->file('image')->move(public_path('images'),$name);
    $article->image= $name;
    $article->save();

    return response()->json(['message'=>'save successfully'],200);

}
