如何在json对象中验证请求-使用laravel

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Validator;

public function store(Request $request)
{
    // 定义验证规则
    $rules = [
        'name' => 'required|string|max:255',
        'email' => 'required|email|unique:users',
        'password' => 'required|min:6',
    ];

    // 创建验证器实例
    $validator = Validator::make($request->all(), $rules);

    // 验证数据
    if ($validator->fails()) {
        // 如果验证失败，返回错误信息
        return response()->json(['errors' => $validator->errors()], 422);
    }

    // 如果验证通过，继续处理请求
    // ...
}

use Illuminate\Support\Facades\Validator;

Validator::extend('custom_rule', function ($attribute, $value, $parameters, $validator) {
    // 自定义验证逻辑
    return $value === 'expected_value';
});

$rules = [
    'field' => 'custom_rule',
];
