无法使用Ajax jQuery下载Excel文件 [英] unable to download excel file using ajax jquery

问题描述

我有

$.ajax({
   url: 'service url',
   type: 'POST',
   async : true,
   contentType: false,
   processData: false,
   cache: false,
   success: function(data){

   },
   error: function(err){}
});

我可以在chrome检查器的Content-disposition中看到该文件，并且响应在检查器中显示一个加密的值.

I can see the file in my Content-disposition in the chrome inspector and the response shows an encrypted value in the inspector.

但是，没有文件正在下载.这里缺少什么?

However, no file is being downloaded. What is missing here?

推荐答案

Content-Disposition将影响在浏览器窗口中加载资源时发生的情况.

Content-Disposition will influence what happens when you load a resource in a browser window.

当您使用JavaScript手动处理响应时，它什么也没做.

It doesn't do anything when you are handling the response manually with JavaScript.

如果要从那时开始触发下载，则需要处理响应，生成data:方案URI并将其设置为location.

If you want to trigger a download from that point, you'd need to handle the response, generate a data: scheme URI and set location to it.

首先将表单提交到目标URL会更简单(除非您不需要POST，在这种情况下，您只需为其设置location即可).

It would be simpler to submit a form to the destination URL in the first place (unless you don't need POST in which case you can just set location to it).
