我们网络服务器上发票的示例链接:
http://billing/view/invoice?id=1
这会在浏览器中显示发票。
要将其保存为PDF,我尝试了:
<?php
function file_get_contents_curl($url) {
$ch = curl_init();
curl_setopt($ch, CURLOPT_AUTOREFERER, TRUE);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
$data = curl_exec($ch);
curl_close($ch);
return $data;
}
require_once("dompdf/dompdf_config.inc.php");
$dompdf = new DOMPDF();
$invoice = file_get_contents_curl('view/invoice?id=1');
$dompdf->load_html($invoice);
$dompdf->set_paper('a4');
$dompdf->render();
$dompdf->stream("dompdf_out.pdf", array("Attachment" => false));
exit(0);
?>
这显示空白页面,没有发票或PDF。
如果我改变
$invoice = file_get_contents_curl('view/invoice?id=1');
$dompdf->load_html($invoice);
到
$invoice = "Hello";
$dompdf->load_html($invoice);
然后显示包含“Hello”的PDF,因此捕获动态PHP发票时似乎存在问题。
错误报告显示:
Warning: file_get_contents(view/order.php?id=1432923): failed to open stream: No error in C:\inetpub\wwwroot\billing\test.php on line 6
答案 0 :(得分:2)
尝试在以下位置添加完整网址:
$invoice = file_get_contents_curl('http://...view/invoice?id=1');
