使用maatwebsite / excel的问题：C：\ Users \ \ AppData \ Local \ Temp \ laravel-excel-k5R8qyVIzkH8X0m5YwHyC2IOznrThvdk是无效的HTML文件

Question

我正在尝试通过maatwebsite / excel进行excel导出，但始终出现以下错误：

C:\Users\<My Laravel project directory>\vendor\phpoffice\phpspreadsheet\src\PhpSpreadsheet\Reader\Html.php:592

public function loadIntoExisting($pFilename, Spreadsheet $spreadsheet)

{

    // Validate

    if (!$this->canRead($pFilename)) {

        throw new Exception($pFilename . ' is an Invalid HTML file.');

    }

我的控制器：

return Excel::download(new ContractsExport($contracts, $active), 'solic_contrat_' . date('d-m-Y') . '_' . time() . '.xlsx');

我的导出文件：

<?php

namespace App\Exports;

use App\Contract;
#use Maatwebsite\Excel\Concerns\FromCollection;
use Maatwebsite\Excel\Concerns\Exportable;
use Illuminate\Contracts\View\View;
use Maatwebsite\Excel\Concerns\FromView;

class ContractsExport implements FromView
{
    use Exportable;

    protected $contracts;
    protected $active;

    public function __construct($contracts = null, $active = null)
    {
        $this->contracts = $contracts;
        $this->active = $active;
    }

    public function view(): View
    {
        $contracts = $this->contracts;
        $active = $this->active;
        return view("exports.contracts", compact("contracts", "active"));
    }
}

刀片模板：

[Laravel-excel文档中肯定缺少某些内容，但是现在我只是在圈子里走路。
提前感谢任何希望帮助我的人

我找到了解决问题的方法：我的.blade.php文件保存为带有BOM的UTF-8编码。使用编码UTF-8保存视图可以解决此问题。
