Handle file download js request.get

This will pass the incoming bytes from your read-stream to the write-stream and ultimately flush every piece of the image to a local file. This function defines a static URL and path to the local image file. You could pass both variables as function parameters to create a more general download method. This signals a successful data transmission. At this point, resolve the promise to complete the file transfer. To recognize error situations, listen for the error event as well. Can this be done by calling same URL using Ext.

I believe then I'll have to handle file coming in the response within success callback. And given that it's huge enterprise webapp impacting millions of users mostly using IE, I wanted to avoid using modern APIs which are obviously tempting but not supported on IE, like always. You want to put a request body in a GET request? This isn't a typical application of the GET protocol though not explicitly disallowed by the spec , so ExtJS doesn't support it out-of-the-box. You can see in the ExtJS source code 4.

This answer has more details , but the gist is "Write a proxy that will rewrite the request for you". If you just want the file to download, a common method is to embed an empty, hidden IFRAME in your document, then set the "src" attribute to the URL for the get request. This does not answer your question directly.

Well, as easy as vertically centering content in divs! Flexbox is cheating! Liked this post? Glad to hear that! But in some cases the web application may want to handle the download part itself, rather than leaving it to the browser. It may have its own reasons like showing the download progress of the file in the applicaton's UI itself.

Another reason may be monetization - the application can show an advertisement to the user while the file is being downloaded. This tutorial shows how to make an AJAX request to download a file, and showing the download percentage completed.
