PHP + PDF, how to save a downloaded PDF using curl?
提问by Kuba
Welcome
欢迎
I have a little problem with saving the downloaded pdf on the page. To download pdf I use Curl:
我在页面上保存下载的 pdf 时遇到了一些问题。要下载 pdf，我使用 Curl：
$CurlConnect = curl_init();
curl_setopt($CurlConnect, CURLOPT_URL, 'http://website.com/invoices/download/1');
curl_setopt($CurlConnect, CURLOPT_POST, 1);
curl_setopt($CurlConnect, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt($CurlConnect, CURLOPT_POSTFIELDS, $request);
curl_setopt($CurlConnect, CURLOPT_USERPWD, $login.':'.$password);
$Result = curl_exec($CurlConnect);
Now in $Result(string) i have all PDF file content. And now begins my problem. I would like to save the downloaded pdf:
现在在$Result(string) 我有所有的 PDF 文件内容。现在开始我的问题。我想保存下载的pdf：
header('Cache-Control: public');
header('Content-type: application/pdf');
header('Content-Disposition: attachment; filename="new.pdf"');
header('Content-Length: '.filesize($Result));
readfile($Result);
Unfortunately, when I save or open a new PDF file, I get a blank document. Perhaps the problem is with the last lines of:
不幸的是，当我保存或打开一个新的 PDF 文件时，我得到一个空白文档。也许问题出在最后几行：
header('Content-Length: '.filesize($Result));
readfile($Result);
Unfortunately, I do not know what to change them to make it work ... I ask for your help. Thanks
不幸的是，我不知道如何更改它们以使其工作......我请求您的帮助。谢谢

Both filesizeand readfileaccepts files as arguments. You are providing a string instead of a file.
无论文件大小和ReadFile的接受文件作为参数。您提供的是字符串而不是文件。
Please try this.
请试试这个。
$CurlConnect = curl_init();
curl_setopt($CurlConnect, CURLOPT_URL, 'http://website.com/invoices/download/1');
curl_setopt($CurlConnect, CURLOPT_POST, 1);
curl_setopt($CurlConnect, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt($CurlConnect, CURLOPT_POSTFIELDS, $request);
curl_setopt($CurlConnect, CURLOPT_USERPWD, $login.':'.$password);
$Result = curl_exec($CurlConnect);
header('Cache-Control: public');
header('Content-type: application/pdf');
header('Content-Disposition: attachment; filename="new.pdf"');
header('Content-Length: '.strlen($Result));
echo $Result;

Maybe that:
也许是：
// ...
$Result = curl_exec($CurlConnect);
$file = 'file.pdf';
$fileName = 'fileName.pdf';
file_put_contents($file, $Result);
and than:
然后：
header('Content-type: application/pdf');
header('Content-Disposition: inline; filename="' . $filename . '"');
header('Content-Transfer-Encoding: binary');
header('Content-Length: ' . filesize($file));
header('Accept-Ranges: bytes');
readfile($file);
I hope I helped!
我希望我有所帮助！
