问题按照评论区大佬方案已解决

非 ajax 表单验证错误会跳转的。

估计是跳转到首页，而你首页是空白的。

dd(request()->ajax())

添加请求头:X-Requested-With: XMLHttpRequest

添加请求头:Accept:application/json告诉服务器期望接收到的数据类型是json格式也可以

FormRequest 验证问题

• router

Route::post('/register', [AuthController::class, 'register']);

• AuthController

namespace App\Http\Controllers;

use App\Http\Requests\RegisterRequest;
use App\Models\User;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use Illuminate\Support\Facades\Hash;

public  function  register(RegisterRequest $request, User $user)
{
    $user->name = $request->input('name');
    $user->email = $request->input('email');
    $user->password = Hash::make($request->input('password'));
    $user->save();

    return response()->json([
        'code' => 0,
        'message' => '用户注册成功',
        'user' => $user
    ], 201);
}

• RegisterRequest

namespace App\Http\Requests;

use Illuminate\Foundation\Http\FormRequest;

class RegisterRequest extends FormRequest
{
    public function authorize(): bool
    {
        return true;
    }

    public function rules(): array
    {
        return [
            'name' => ['required', 'between:3,20', 'regex:/^[a-z]\w+$/i', 'unique:users,name'],
            'email' => ['required', 'email', 'unique:users,email'],
            'password' => ['required', 'between:5,20', 'confirmed'],
        ];
    }
}

图片一直弄不上来 使用apifox模拟请求结果就只看到了200状态码
响应参数那是空白
能知道的就是确实进行了验证 在rules方法内可以截取到数据
