如何将quickchart.io api生成的图像插入到laravel dompdf中

composer require barryvdh/laravel-dompdf

'providers' => [
    ...
    Barryvdh\DomPDF\ServiceProvider::class,
],

php artisan vendor:publish --provider="Barryvdh\DomPDF\ServiceProvider"

use Dompdf\Dompdf;

class ChartController extends Controller
{
    public function generateChart()
    {
        // 使用quickchart.io API生成图像的代码
        $chartUrl = "https://quickchart.io/chart/render/zm-8b7330b9-38fd-4e09-a031-4c7e1c80cf52";
        
        // 创建一个Dompdf实例
        $dompdf = new Dompdf();

        // 获取图像内容
        $imageContent = file_get_contents($chartUrl);

        // 将图像内容插入到dompdf
        $dompdf->getOptions()->setIsHtml5ParserEnabled(true);
        $dompdf->loadHtml('<img src="data:image/png;base64,' . base64_encode($imageContent) . '">');
        $dompdf->setPaper('A4', 'landscape');

        // 渲染PDF
        $dompdf->render();

        // 将PDF保存到本地或输出到浏览器
        $dompdf->stream("chart.pdf", array("Attachment" => false));
    }
}

Route::get('/generate-chart', 'ChartController@generateChart');
