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

问题描述

这里是我正在使用的PHP代码。

  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）; 
} 
  

这是jQuery。

$ b $（$ {code $ $ $''''''''''''''''''''''''''''''''''''''' b $ b $ .ajax（{
type：'POST'，
url：App / Ajax / Excel / Download.php，
data：formData
}）;
}）;

是不是可以这样下载？我尝试了谷歌搜索，有人建议这样做是一样的。但是在我的控制台中，它显示一些垃圾值作为响应。

我在哪里出错？

谢谢

解决方案

您可以简单地向您的 App / Ajax / Excel / Download发送POST请求。 php 页面，您希望使用的表单数据，并忘记使用jQuery的AJAX。如果您的回复标头是正确的，当您发布erp_customerinvoice表单时，默认情况下，浏览器将显示一个下载文件对话框，您将不会浏览到Download.php页面，因为响应标头将阻止重定向。 / p>

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

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);
}

and this is the jQuery.

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

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.

where am i going wrong?

thank you..

解决方案

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.
