快速呈现渲染视图并同时下载文件 [英] Express render view and download file at the same time

问题描述

我想使用express渲染文件并同时下载文件

I would like to use express to render a file AND download a file at the same time

我当前的代码如下:

res.attachment('filename.csv');
res.render('pages/result', { data });

但是，如果我这样做，它只会下载数据而不会呈现视图

However, if I do this, it only downloads the data and does not render the view

我想要呈现一个成功页面，然后发送文件以便下载

What I want is to render a success page, and then send the file so that it downloads

我需要使用1个端点来完成此操作，因为我需要生成文件，并且只有在文件成功的情况下，我才会呈现成功页面

I need this to be done with 1 endpoint, because, I need to generate the file and only if it is successful, I would render the success page

我可以使用1个端点执行此操作吗?

Am I able to do this with 1 endpoint?

谢谢

推荐答案

将文件的路径作为变量发送到渲染页面，并在javascript中编写一个函数以自动下载文件.

send the path of the file to the render page as variable and write a function in javascript to download the file automatically.

res.render('pages/result', { path: '../folder/filename.csv'});

渲染页面上

<iframe id="my_iframe" style="display:none;"></iframe>
<script>
function Download(url) {
    document.getElementById('my_iframe').src = #{path};
};
</script>

使用Javascript/jQuery下载文件
