如何在 Laravel 中下载运单 pdf 而不是在浏览器中打开

Question

下面是我的 Laravel 函数，用于从快递提供商处生成运单。目前，代码运行良好，但运单 pdf 直接在浏览器中打开。我如何强制它下载 pdf 文件？

public function awb(Request $request)
{
    function e($str) {print'<pre>';print_r($str);print'</pre>';}

    $url = 'http://web.com/print/print.action';

    $key = $request->key;
    $billCode = $key;

    $data = array(
    'billcode' => $billCode,
    'account' => 'xxx',
    'password' => 'xxx',
    'customercode' => 'xxx',
    );

    $t = array('logistics_interface' => json_encode($data), 'msg_type' =>
    '1', 'data_digest' => md5($billCode));

    $s = curl_init();

    curl_setopt($s,CURLOPT_URL,$url);
    curl_setopt($s,CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($s,CURLOPT_RETURNTRANSFER,true);
    curl_setopt($s,CURLOPT_POSTFIELDS,http_build_query($t));
    header('Content-type: application/pdf');

    $r = curl_exec($s);
    curl_close($s);

    e($r);
}

您需要将请求保存到文件并return下载

public function awb(Request $request)
{
    function e($str) {print'<pre>';print_r($str);print'</pre>';}

    $url = 'http://web.com/print/print.action';

    $key = $request->key;
    $billCode = $key;

    $data = array(
    'billcode' => $billCode,
    'account' => 'xxx',
    'password' => 'xxx',
    'customercode' => 'xxx',
    );

    $t = array('logistics_interface' => json_encode($data), 'msg_type' =>
    '1', 'data_digest' => md5($billCode));

    $s = curl_init();

    curl_setopt($s,CURLOPT_URL,$url);
    curl_setopt($s,CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($s,CURLOPT_RETURNTRANSFER,true);
    curl_setopt($s,CURLOPT_POSTFIELDS,http_build_query($t));
    //header('Content-type: application/pdf');

    $r = curl_exec($s);
    curl_close($s);
    
    $f = 'pdf/download.pdf';
    Storage::disk('local')->put($f, $r);
    return Response::download(Storage::disk('local')->getDriver()->getAdapter()->applyPathPrefix($f));
}
