Question

我想从oracle下载blob文件，即PDF文件，这是我获取和下载文件的代码：

<?php
$conn = ocilogon('user', 'pass', '//localhost/XE');
$sql = "SELECT PDFFILE FROM TFILE";
    $stid = ociparse($conn,$sql);
    ociexecute($stid);
    $rowResult = ocifetch($stid);
    settype($arrayResult,"array");
if($rowResult != null){
            header("Content-Type: application/octet-stream");
            header('Content-Disposition: attachment; filename="' . OCIResult($stid,'PDFFILE') . '"');    
            header("Content-Length: " . filesize(OCIResult($stid,'PDFFILE')->load()));
            header('Content-Disposition: attachment; header("Content-Transfer-Encoding: binary\n");
    }
    ?>

但是当我运行此代码时，我得不到pdf文件.. 我的代码有问题吗？

Answer 1

header("Content-Type: application/octet-stream");
header('Content-Disposition: attachment; filename="' . OCIResult($stid,'PDFFILE') . '"');    
header("Content-Length: " . filesize(OCIResult($stid,'PDFFILE')->load()));
header('Content-Disposition: attachment; header("Content-Transfer-Encoding: binary\n");

您要发送Content-Disposition标题两次。您可能甚至不需要第二个，客户端应该知道它需要知道的来自Content-Type标头的流。省略第二个Content-Disposition，这样你就不会覆盖具有文件名的标题。
