laravel-admin 使用laravelS 时excel导出报错修改

1、excel 导出类中重构export方法，用一个自定义异常类用来替代exit 实现跳出执行到输出。

这里没法用return ，因为export方法返回会回到vendor方法中继续执行其他输出。

namespace App\Admin\Excel\Exporters;

use Encore\Admin\Grid\Exporters\ExcelExporter;
use Maatwebsite\Excel\Concerns\Exportable;
use Maatwebsite\Excel\Concerns\WithMapping;

class AppointOrdersExport extends ExcelExporter implements WithMapping
{
    use Exportable;
    protected $fileName = '购票记录.xlsx';

    protected $columns = [
		'order_sn'=>'订单号',
		'pay_no'=>'支付流水号',
		'order_num'=>'购票数量',
		...
    ];

	public function map($order) : array
    {
		$pay_types = ['0'=>'微信', '1'=>'小程序', '2'=>'支付宝'];
		$statuss = [
			'0'=>'待支付',
			'1'=>'已支付未核销',
			'2'=>'已支付',
			'3'=>'已取消',
			'-1'=>'已退款'
		];
        return [
            $order->order_sn,
            $order->pay_no,
            $order->order_num,
            .....
        ];
    }
    
    public function export()
    {
        throw new \App\Exceptions\SwooleExitException($this->download($this->fileName)->prepare(request()));
    }
}

2、创建一个自定义异常类用来替代exit 实现跳出执行到输出

namespace App\Exceptions;

use Throwable;

use Exception;
use Illuminate\Http\Request;

class SwooleExitException extends Exception

{

    protected $response;

    public function __construct($response,$message = "", $code = 0, Throwable $previous = null)

    {

        $this->response = $response;

        parent::__construct($message, $code, $previous);

    }
    
    public function render(Request $request) {
        return $this->response->prepare($request);
    }

}

 3、把这个异常类放到 App\Exceptions\handle.php 的 $dontReport中，因为没必要记录这个异常

protected $dontReport = [
        //
        SwooleExitException::class,
    ];
