laravel-admin 使用laravels时，excel

预处理

新建自定义异常类

<?php

namespace App\Exceptions;

use Throwable;

use Exception;

class SwooleExitException extends Exception

{

    protected $response;

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

    {

        $this->response = $response;

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

    }

    //获取响应内容

    public function getResponse(){

        return $this->response;

    }

}

在Handler.php中，render方法中添加代码

protected $dontReport = [

    //

    SwooleExitException::class

];



public function render($request, Exception $exception)

{



    if ($exception instanceof SwooleExitException) {

        //直接调用perpare

        return $exception->getResponse()->prepare($request);

    }



}

swoole_exit 为自定义的全局函数

if (!function_exists('swoole_exit')){

    function swoole_exit($response)

    {

        throw new App\Exceptions\SwooleExitException($response);

    }

}

接下来是改框架。小弟不才。没有想到其他办法。希望各位大神指点迷津。

第一步

修改Encore\Admin\Grid\Exporters\CsvExporter.php 文件

public function export()

{

    .....

    ....

    response()->stream($response, 200, $this->getHeaders())->send();



    exit;

}

处理掉exit

改为

public function export()

{

    .....

    ....

  swoole_exit(response()->stream($response, 200, $this->getHeaders()));

}

第二步

Encore\Admin\Middleware\Pjax.php

跟第一步同样道理，处理掉exit方式，修改为请求返回的形式

public static function respond(Response $response)

    {

        $next = function () use ($response) {

            return $response;

        };

        swoole_exit((new static())->handle(Request::capture(), $next));



//        (new static())->handle(Request::capture(), $next)->send();

//        exit;

    }

第三步

Encore\Admin\Grid\Exporters\ExcelExporter

public function export()

{

//        $this->download($this->fileName)->prepare(request())->send();

        swoole_exit($this->download($this->fileName)->prepare(request()));

//        exit;

}
