Download a serialized file using ajax get request

Question

I am facing an issue in sending an ajax get request to download a file served by a REST API in java.

The REST api

 @GET
 @Path("/{modelName}/export")
 @Produces(MediaType.APPLICATION_OCTET_STREAM)

The API is working fine. The problem is with my ajax call

  $.ajax({
                type: "GET",
                url: serverUrl+'/api/models/'+modelName+'/export',
                success : function(res){
                    alert("success");
                    console.log(res);
                },
                error : function(res){
                    alert("error");
                    console.log(res);                
                }
            });

When this call is executed I need the file to be downloaded. How do I modify the ajax call in order to that?

i am getting a success alert when I execute it, and some random strings are printed in the console.

You don't need ajax when you download file. Becouse anyway file downloads async by browsers.

You can use plain html for this purpouse:

<a href="YourPath">Download File</a>

But if you want to get file with js you can do it like this:

window.location.href = serverUrl+'/api/models/'+modelName+'/export';
