欢迎
将下载的pdf保存在页面上有一点问题。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);
现在在$ Result(字符串)中我拥有所有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);
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);
不幸的是,我不知道要改变它们以使其发挥作用...我请求你的帮助。谢谢
filesize和readfile都接受文件作为参数。您提供的是字符串而不是文件。
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;
也许那样:
// ...
$Result = curl_exec($CurlConnect);
$file = 'file.pdf';
$fileName = 'fileName.pdf';
file_put_contents($file, $Result);
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);
我希望我帮忙!
