PHP + PDF，如何使用curl保存下载的PDF？

问题描述

欢迎

我在网页上保存下载的pdf文件有点问题。下载pdf我使用Curl：

I have a little problem with saving the downloaded pdf on the page. To download pdf I use 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);

现在在 $ Result （字符串）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：

Now in $Result(string) i have all PDF file content. And now begins my problem. I would like to save the downloaded pdf:

header('Cache-Control: public');
header('Content-type: application/pdf');
header('Content-Disposition: attachment; filename="new.pdf"');
header('Content-Length: '.filesize($Result));
readfile($Result);

不幸的是，当我保存或打开一个新的PDF文件时，也许问题是最后一行：

Unfortunately, when I save or open a new PDF file, I get a blank document. Perhaps the problem is with the last lines of:

header('Content-Length: '.filesize($Result));
readfile($Result);

不幸的是，我不知道如何改变它们使它工作...我要求你帮帮我。感谢

Unfortunately, I do not know what to change them to make it work ... I ask for your help. Thanks

推荐答案

$CurlConnect = curl_init();
curl_setopt($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;

请尝试这个。

和接受文件作为参数。您提供的是字符串，而不是文件。

filesize and readfile accepts files as arguments. You are providing a string instead of a file.
