ThinkPHP5 自定义异常

1.配置config.php

自定义异常路径：

// 默认AJAX 数据返回格式,可选json xml ...
'default_ajax_return'    => 'json',

'exception_handle'       => '\\app\\exceptions\\ExceptionHandle',

2.

--------------------------------------------------------

<?php

namespace app\exceptions;

use think\exception\Handle;

/**
 * Class ExceptionHandle
 * 全局异常处理
 * @package app\exceptions
 */
class ExceptionHandle extends Handle
{
    /**
     * 渲染方式
     * @param Exception $e
     * @return \think\Response
     */
    public function render(\Exception $e)
    {
        if ($e instanceof \app\exceptions\Exception) {
            return json([
                'code' => $e->getCode(),
                'message' => $e->getMessage()
            ], $e->getCode());
        }
        return parent::render($e);
    }
}

<?php

namespace app\exceptions;

use \Throwable;

/**
 * Class Exception
 * 异常基类
 * @package app\exceptions
 */
class Exception extends \Exception
{
    public function __construct(string $message = "", int $code = 0, Throwable $previous = null)
    {
        parent::__construct($message, $code, $previous);
