php - 在php中下载pdf的文件代码

Question

$path = BASE_URL."/pdf/"; 
$filename= $path.basename($_GET['download_file']);

header("Cache-Control: public");
header("Content-Description: File Transfer");
header('Content-disposition: attachment; 
filename='.basename($filename));
header("Content-Type: application/pdf");
header("Content-Transfer-Encoding: binary");
header('Content-Length: '. filesize($filename));
readfile($filename);
exit;

此代码有效，但我Error in reading pdf file在打开下载的 pdf 时得到了。在上面的代码中，我从该位置获取文件http://localhost//eec//pdf/CV_Prabin Mishra.pdf

Answer 1

BASE_URL最后可能有一个斜线，所以你不需要额外的：

$path = BASE_URL."pdf/"; 

Answer 2

我看不到您在哪里设置了 $filename 的值，您在 $fullPath 中设置了 PDF 的位置，然后使用 $filename 将其读出。我认为代码应该是

$path = BASE_URL."/pdf/"; 
$fullPath = $path.basename($_GET['download_file']);

header("Cache-Control: public");
header("Content-Description: File Transfer");
header('Content-disposition: attachment; 
filename='.basename($fullPath));
header("Content-Type: application/pdf");
header("Content-Transfer-Encoding: binary");
header('Content-Length: '. filesize($fullPath));
readfile($fullPath);
exit;
