laravel默认的异常处理是展示出异常的界面，不能够完善的捕获异常并响应为json格式数据

需要修改下以下文件

app/Exceptions/Handler.php

<?php

namespace App\Exceptions;

use App\Lib\ApiHelper\ApiCode;
use Illuminate\Foundation\Exceptions\Handler as ExceptionHandler;
use Illuminate\Support\Arr;
use Illuminate\Validation\ValidationException;
use Symfony\Component\HttpKernel\Exception\HttpException;
use Throwable;

class Handler extends ExceptionHandler
{
    /**
     * A list of the exception types that are not reported.
     *
     * @var array
     */
    protected $dontReport = [
        //
    ];

    /**
     * A list of the inputs that are never flashed for validation exceptions.
     *
     * @var array
     */
    protected $dontFlash = [
        'current_password',
        'password',
        'password_confirmation',
    ];

    /**
     * Register the exception handling callbacks for the application.
     *
     * @return void
     */
    public function register()
    {
        $this->reportable(function (Throwable $e) {
            //
        });
    }

    public function render($request, Throwable $e)
    {
        switch ($e) {
            case $e instanceof ValidationException:
                $response = [
                    'errmsg' => Arr::first($e->errors())[0] ?? '请求参数不合法',
                    'errcode' => ApiCode::FAILED,
                    'data' => new \stdClass()
                ];

                break;
            case $e instanceof HttpException:
                $response = [
                    'errmsg' => ApiCode::getMessage(ApiCode::FAILED_HTTP),
                    'errcode' => ApiCode::FAILED_HTTP,
                    'data' => new \stdClass()
                ];

                break;
            default:
                $code = $e->getCode() ?: ApiCode::FAILED;
                $response = [
                    'errmsg' => $e->getMessage() ?: ApiCode::getMessage($code),
                    'errcode' => $code,
                    'data' => new \stdClass()
                ];
        }

        if (config('app.debug')) {
            $response['exception'] = get_class($e);
            $response['message'] = $e->getMessage();
            $response['trace'] = $e->getTrace();
        }
        return response()->json($response,200,[],JSON_UNESCAPED_SLASHES|JSON_UNESCAPED_UNICODE);
    }
}

ApiCode类

app/Lib/ApiHelper/ApiCode.php

<?php
namespace App\Lib\ApiHelper;

class ApiCode
{
    const OK = 20000;
    const FAILED_PARAMES = 40001;
    const FAILED = 50000;
    const FAILED_NO_EXIST = 50001;
    const FAILED_AUTH_EXPIRED = 50002;
    const FAILED_HTTP = 50003;
    public static $messageMapper = [
        self::OK => '成功',
        self::FAILED => '失败',
        self::FAILED_HTTP => 'HTTP请求异常',
        self::FAILED_NO_EXIST => '授权码不存在',
        self::FAILED_AUTH_EXPIRED => '授权码过期'
    ];

    /**
     * Get code message
     * @param $code
     * @return string
     */
    public static function getMessage($code)
    {
        return self::$messageMapper[$code] ?? '服务器未知错误';
    }
}
