php - 如何仅从 laravel FormRequest 获取经过验证的数据？

Question

假设我有以下自定义请求:

class PlanRequest extends FormRequest
{
    // ...


    public function rules()
    {

        return
        [
            'name'              => 'required|string|min:3|max:191',
            'monthly_fee'       => 'required|numeric|min:0',
            'transaction_fee'   => 'required|numeric|min:0',
            'processing_fee'    => 'required|numeric|min:0|max:100',
            'annual_fee'        => 'required|numeric|min:0',
            'setup_fee'         => 'required|numeric|min:0',
            'organization_id'   => 'exists:organizations,id',
        ];
    }
}

当我从 Controller 访问它时，如果我这样做 $request->all() ，它为我提供了ALL数据，包括不应该传递的额外垃圾数据。

public function store(PlanRequest $request)
{
    dd($request->all());
    // This returns
    [
        'name'              => 'value',
        'monthly_fee'       => '1.23',
        'transaction_fee'   => '1.23',
        'processing_fee'    => '1.23',
        'annual_fee'        => '1.23',
        'setup_fee'         => '1.23',
        'organization_id'   => null,
        'foo'               => 'bar', // This is not supposed to show up
    ];
}

如何在不手动执行 $request->only('name','monthly_fee', etc...) 的情况下仅 验证数据？

Answer 1

$request->validated()将仅返回经过验证的数据。

示例:

public function store(Request $request)
{
    $request->validate([
        'title' => 'required|unique:posts|max:255',
        'body' => 'required',
    ]);

    $validatedData = $request->validated();

}

备选方案:

$request->validate([rules...]) 如果验证通过，则返回唯一经过验证的数据。

示例:

public function store(Request $request)
{
   
    $validatedData = $request->validate([
        'title' => 'required|unique:posts|max:255',
        'body' => 'required',
    ]);

}
