laravel中的验证

   $rules = [
                ‘password‘=>‘required|between:6,20|confirmed‘,
            ];

            $message = [
                ‘password.required‘=>‘新密码不能为空！‘,
                ‘password.between‘=>‘新密码必须在6-20位之间！‘,
                ‘password.confirmed‘=>‘新密码和确认密码不一致！‘,//password_confirmation
            ];
            //验证规则
            $validator = Validator::make($input,$rules,$message);
            //返回boolean
            if(!$validator->passes()) {
                return back()->withErrors($validator);
            }
