我使用API生成pdf文档。在这个API的文档中,我有:
http://...../view_awb.php?user=nume_utilizator&parola=123456&awb=CGS12345678A
If success, the view_awb.php file will return a PDF document
接下来,我有这些代码:
require "../dbcommon2.php";
$url = "http://webexpress.cargus.ro/custom_print/shipment_import/view_awb.php?user=canai_test&parola=test&awb=TSD21185178T";
$pdf = file_get_contents($url, false);
require_once("../../dompdf/dompdf_config.inc.php");
$dompdf = new DOMPDF();
$dompdf->load_html($pdf);
$dompdf->render();
$dompdf->stream("sample.pdf");
所有看起来都正确,但是当我打开pdf文件时,我只看到
%PDF-1.3 3 0 obj > endobj 4 0 obj > stream xY[ sÚ8¾ï¯Ðe{UgÙ¹£tèd!KHg/:³ãñ.`Öì7ýõß«Æ6HM;M¤WÞãG¡oýûáHL"ð¥D¦é4Á
问题出在哪里?如何正确生成pdf文件? 我用Adobe Reader打开pdf文件sample.pdf
答案 0 :(得分:1)
看起来http://webexpress.cargus.ro/custom_print/shipment_import/view_awb.php?user=canai_test&parola=test&awb=TSD21185178T的可用内容已经是.pdf。
您可以尝试(我基于http://davidwalsh.name/curl-download上的示例):
<?php
header("Content-Type: application/pdf");
function get_data($url)
{
$ch = curl_init();
$timeout = 5;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
$url = "http://webexpress.cargus.ro/custom_print/shipment_import/view_awb.php?user=canai_test&parola=test&awb=TSD21185178T";
$pdf = get_data($url);
echo $pdf;
?>
