[laravel] laravel验证请求参数

laravel 验证请求参数，有自带的规则，如果有特殊的规则，可以自己写正则验证逻辑

比如验证手机号

在控制器文件中可以直接这样编写

默认情况下，如果验证通过，你的代码会继续正常运行。如果验证失败，则会抛出异常，并自动将对应的错误响应返回给用户。 在传统 HTTP 请求下，会生成一个重定向响应， 而对于 AJAX 请求则会发送 JSON 响应，这里的JSON响应必须得传递指定的JSON header头才行

这里我修改了异常处理类,继承类覆盖了render方法，直接全部返回json数据

class QualityController extends Controller
{
    /**
     * 检测参数
     * @param Request $request
     * @return bool
     */
    protected function checkRequestParam(Request $request):array {
        $validateData=$request->validate([
            'phone' => 'required|regex:/^1d{10}$/',
            'city_code' => 'required|numeric',
        ],[
            'required'=>":attribute 字段必填",
            'numeric'=>":attribute 字段必须为数字",
            'regex'=>":attribute 字段手机号格式不正确",
        ]);
        return $validateData;
    }

    /**
     * 同步线索质检
     * @param Request $request
     * @return IlluminateHttpJsonResponse
     */
    public function sync(Request $request){
        $validateData=$this->checkRequestParam($request);
        return $this->responseSuccess($validateData);
    }

效果如这样

有需求的可以参考下面的例子自行修改

        //
    ];

    /**

     *
     * @var array

    protected $dontFlash = [
        'current_password',
        'password',
        'password_confirmation',
    ];

    /**
