Question

我想通过一个支架哨所下载一个pdf文档。我试图这样做:

$( #downloadPdf ).click(function() {
    var id = $( #fileId ).val();

    $.ajax({
        type: "POST",
        url: "includes/download_pdf.php",
        data:  file_id=  + id,
        complete: function(data) {
            $( #pdf_results ).html(data.responseText);
        }
    });
});

Code PHP:

<?php 
    $file_name = $_POST[ file_id ]; 
    // We ll be outputting a PDF header( Content-type: application/pdf ); 
    // It will be called downloaded.pdf header( Content-Disposition: attachment; filename=" .$file_name. .pdf" ); 
    // The PDF source is in original.pdf readfile( /var/www/vhosts/domain.nl/private/ .$file_name. .pdf ); 
?>

当我使用该守则时,我会在<代码>#pdf_results上看到所有奇怪的迹象。我想把国防军拯救到我的电脑中,但这项工作十分艰巨。

有些人知道如何解决这一问题?

提前感谢!

你们不需要为此利用美国航天中心。要求使用这样的东西:

$(function(){
    $( #downloadPdf ).click(function(){
        var id = $( #fileId ).val();
        window.open(location.protocol +  //  + location.hostname +  /includes/download_pdf.php?file_id=  + id);
        return false;
    });
});

Cheers!

这里不需要麻省。

Try using Rory McCrossan s solution: POST to server, receive PDF, deliver to user w/ jQuery

要么使用原始材料,要么简单地与档案链接,确保服务器发送正确的头盔(可读到存放处的档案,然后从那里输出:

Answer 3

Have an invisible <iframe/> on the page, and create a <form> with attributes method="POST" action="includes/download_pdf.php" target="name_of_the_iframe", add a <input type="hidden" name="file_id" value="the_value"/> into it, and submit it.

所有这一切都可以在 Java文中完成,而不必将这种标记放在网页上,以保持清扫。而其中没有一个是麻省。

You need to achieve this : I didn t really trace your program but you need the content disposition line in your php to make it work.

<?php
// We ll be outputting a PDF
header( Content-type: application/pdf );

// It will be called downloaded.pdf
**header( Content-Disposition: attachment; filename="downloaded.pdf" );**

// The PDF source is in original.pdf
readfile( original.pdf );
?>

也可以将档案移至一旁,但会带来安全风险,从而成为另一个议题。
