如何从CUrl下载或导出PHP格式的PDF并输出到VUE JS？

<?php
// 使用Curl下载PDF文件
$curl = curl_init();
$fileUrl = 'http://example.com/path/to/file.pdf';
$savePath = '/path/to/save/file.pdf';
$fp = fopen($savePath, 'w');
curl_setopt($curl, CURLOPT_URL, $fileUrl);
curl_setopt($curl, CURLOPT_FILE, $fp);
curl_exec($curl);
curl_close($curl);
fclose($fp);

// 生成PDF文件
require('tcpdf/tcpdf.php');
$pdf = new TCPDF();
$pdf->AddPage();
$pdf->SetFont('Arial', 'B', 16);
$pdf->Cell(0, 10, 'Hello World', 0, 1, 'C');
$pdf->Output('/path/to/save/generated.pdf', 'F');

// 输出PDF文件到浏览器
header('Content-Type: application/pdf');
header('Content-Disposition: inline; filename="generated.pdf"');
readfile('/path/to/save/generated.pdf');
?>
