lumen添加自定义异常

在公用工具类写异常类

<?php

namespace Brady\Tool\Exception;

use Brady\Tool\Constant\ErrorMsg;
use \Exception;

class ExceptionResult extends Exception
{
	const DEFAULT_CODE = 500;

	protected static $messageTemplate = [];

	public static function setMsgTemplate(array $template = [])
	{
		static::$messageTemplate = $template;
	}

	public static function getMsgTemplate()
	{
		return static::$messageTemplate;
	}

	public function errorMsg()
	{
		return "异常信息：文件-".$this->getFile()." 行号-".$this->getLine()."错误码-".$this->getCode()." 信息-".$this->getMessage();
	}

	/**
	 * @param $code
	 * @param bool $isChinese  是否直接抛出中文
	 */
	public  static  function throwException($code,$isChinese = false)
	{
		$class = __CLASS__;
		if($isChinese){
			throw new $class($code,500);
		} else {

			//根据code获取msg
			$msg = static::getMsg($code);
			throw new $class($msg,$code);
		}

	}

	public static  function getMsg($code)
	{
		$template = self::getMsgTemplate();

		if(isset($template[$code])){
			return $template[$code];
		} else {
			$class = __CLASS__;
			throw new $class("错误码未设置".$code);
		}

	}

}

lumen bootstrp的app里面注册服务提供者

$app->register(App\Providers\ExceptionServiceProvider::class);

providers文件夹下新建文件

<?php
/**
 * Created by PhpStorm.
 * User: costa
 * Date: 2019/3/15
 * Time: 14:12
 */

namespace App\Providers;

use Brady\Tool\Exception\ExceptionResult;
use Illuminate\Support\ServiceProvider;

class ExceptionServiceProvider extends ServiceProvider
{
    /**
     *  注册编码信息
     */
    public function register()
    {
        $tpl = require (dirname(__DIR__) . '/Constants/ErrorMsg.php');
        ExceptionResult::setMsgTemplate($tpl);
    }
}

app目录下新建目录 Constants

分别存放错误码和错误信息

ErrorCode.php

<?php
/**
 * Created by PhpStorm.
 * User: costa
 * Date: 2019/3/15
 * Time: 14:23
 */

namespace App\Constants;

class ErrorCode
{
    /**
     * 基本错误码
     */
    const SUCCESS = 200;
    const UNAUTHORIZED = 401;
    const FAIL = 500;

}

ErrorMsg.php

<?php
/**
 * Created by PhpStorm.
 * User: costa
 * Date: 2019/3/15
 * Time: 14:22
 */

namespace App\Constants;

return [
    ErrorCode::SUCCESS      => '成功' ,
    ErrorCode::UNAUTHORIZED => '暂无权限！' ,
    ErrorCode::FAIL         => '失败' ,

];

使用 在控制器里面

<?php

namespace App\Service;

//服务层
use App\Constants\ErrorCode;
use App\Repository\UserRepository;
use Brady\Tool\Exception\ExceptionResult;
use Mockery\Exception;

class UserService
{
	public  $userRepository;

	public function __construct()
	{
		$this->userRepository = new UserRepository();
	}

	public function queryUserList($where)
	{
		$where = ['name'=>"brady"];
		return $this->userRepository->getList($where);
	}

	public function getUserInfo($id)
	{
		try{
			ExceptionResult::throwException(ErrorCode::UNAUTHORIZED);

			return $this->userRepository->getById($id);

		} catch (\Exception $e){
			var_dump($e->getMessage());
		}

	}

}
