下载通过jQuery AJAX后不工作 [英] Downloading Via JQuery AJAX Post not working

问题描述

我想通过使用jQuery POST请求使用Ajax下载文件。

i want to download a file using ajax via post request using jQuery.

下面是PHP code我使用。

here is the PHP code i am using.

if (file_exists($file)) {
    header("Cache-Control: public");
    header("Content-Description: File Transfer");
    header("Content-Disposition: attachment; filename=$file");
    header("Content-Type: application/zip");
    header("Content-Transfer-Encoding: binary");
    readfile($file);
}

和这是jQuery的

$('button.erp_ci_download').click(function(){
    var formData = $('form#erp_customerinvoice').serialize();
    $.ajax({
        type: 'POST',
        url:  "App/Ajax/Excel/Download.php",
        data: formData
    });
});

是不是可以下载这种方式？我尝试使用Google，有些建议是相同的方式，我这样做。但在我的控制台也显示了一些垃圾值作为响应。

is it not possible to download it this way? i tried googling and some suggested it is the same way i am doing it. but in my console it shows some garbage values as response.

我在哪里去了？

感谢你..

推荐答案

您可以简单地发送POST请求到您的应用/阿贾克斯/ EXCEL /的download.php 页面表单数据，你想，忘记使用jQuery的AJAX。如果您的响应报头是正确的，当你发布你的erp_customerinvoice的形式，浏览器将默认情况下，告诉你一个下载文件对话框，你将永远不会浏览到的download.php页面，因为响应头将prevent一个重定向。

You could simply send a POST request to your App/Ajax/Excel/Download.php page with the form data you wish and forget about using jQuery's AJAX. If your response headers are correct, when you post your "erp_customerinvoice" form, the browser will, by default, show you a download file dialog and you will never navigate to the Download.php page because the response headers will prevent a redirect.
