使用javascript将图像下载到我的Web服务器

Question

I want to download image from url say, www.someurl.com/images/a.jpg to server on which my application is running. Can I do this in javascript or I have to make web service and call it?

Answer 1

You can. XMLHTTPRequest if you are using plain js or simply use jquery $.get()

Answer 2

If you're talking about downloading an image from an external website to your own server, not using the clients browser. Then you might want to check out node-wget , which allows you to very easily download a file from your node.js program:

var wget = require('node-wget');
wget(url);

Answer 3

In javascript try using this one

var a = $("<a>")
    .attr("href", "www.someurl.com/images/a.jpg")
    .attr("download", "img.png")
    .appendTo("body");

a[0].click();
a.remove();
