laravel-admin使用laravels时，excel导出异常的问题

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; }
