@d-healey or use Engine.extendTimeout()

d.healey

I've set the timeout to 10 seconds but I'm still hitting the issue. Here's my call

    Server.callWithGET("wp-json/my/v1/products", {}, function(status, response)
    {            
            for (r in response)
            {
                var file = FileSystem.getFolder(FileSystem.Downloads).getChildFile(r.name + ".jpg");   
                var url = r.imageUrl.replace(Webstore.baseURL, ""); // Time out is on this line
                Server.downloadFile(url, {}, file, downloadCallback);
            }
                
    });

I don‘t see the extend timeout call in the snippet ;)

Call it in the loop and you should be fine.

d.healey

@Christoph-Hart Oh ok, I was calling it at the start of on init

d.healey

I'm going to try the exendTimeout thing now, but while I was waiting 7 whole minutes! for your reply I found another solution

var files = {};
var urls = {};
            
for (r in response)
{
    files[r.name] = FileSystem.getFolder(FileSystem.Downloads).getChildFile(r.name + ".jpg");   
    urls[r.name] = r.image.replace(Webstore.baseURL, "");
}
            
for (r in response)
    Server.downloadFile(urls[r.name], {}, files[r.name], downloadCallback);

Nice to see emojis working again :D :p ;)

Update: And I confirm the timeout method works!

I have a strange issue (bug maybe) with the this.data.finished clause being accessed more than once for each download.

Content.makeFrontInterface(600, 500);

Console.clear();

reg count = 0;

Server.setBaseURL("https://forum.hise.audio/uploads/profile");

const images = ["1-profileimg.jpg", "12-profileimg.jpg", "67-profileavatar.jpeg", "121-profileimg.jpg", "338-profileavatar.png"];

function downloadCallback()
{
    if (this.data.finished)
    {
        Console.print(count + " : " + this.getDownloadedTarget().toString(1));
        count++;
    }
}

reg f;

for (i = 0; i < images.length; i++)
{
    f = FileSystem.getFolder(FileSystem.Downloads).getChildFile(images[i]);
    Server.downloadFile(images[i], {}, f, downloadCallback);    
}

I thought it might be something to do with the loop or reusing the f variable so I also wrote it out the long way and the result is the same

reg f0 = FileSystem.getFolder(FileSystem.Downloads).getChildFile(images[0]);
Server.downloadFile(images[0], {}, f0, downloadCallback);

var f1 = FileSystem.getFolder(FileSystem.Downloads).getChildFile(images[1]);
Server.downloadFile(images[1], {}, f1, downloadCallback);

var f2 = FileSystem.getFolder(FileSystem.Downloads).getChildFile(images[2]);
Server.downloadFile(images[2], {}, f2, downloadCallback);

var f3 = FileSystem.getFolder(FileSystem.Downloads).getChildFile(images[3]);
Server.downloadFile(images[3], {}, f3, downloadCallback);

var f4 = FileSystem.getFolder(FileSystem.Downloads).getChildFile(images[4]);
Server.downloadFile(images[4], {}, f4, downloadCallback);

d.healey

Any ideas? Is it possible that there is some shared data between the different instances of the downloadCallback so as each download finishes it's triggering the callback for other downloads?

I think I've found a solution/workaround, recursion. Each download complete triggers the next download start.

Content.makeFrontInterface(600, 500);

Console.clear();

Server.setBaseURL("https://forum.hise.audio/uploads/profile");

const images = ["12-profileimg.jpg", "67-profileavatar.jpeg", "121-profileimg.jpg", "338-profileavatar.png"];

function downloadCallback()
{
    if (this.data.finished)
    {        
        if (count < images.length-1)
        {
            count++;
            startNextDownload(images[count]);
        }
    }
}

inline function startNextDownload(fileName)
{
    Console.print(fileName);
    local f = FileSystem.getFolder(FileSystem.Downloads).getChildFile(fileName);
    Server.downloadFile(fileName, {}, f, downloadCallback);
}

reg count = 0;
startNextDownload(images[0]);

I fixed a few things about this, however it still is a bit glitchy if you're hammering the queue - I haven't been able to track down the reason, but sometimes the URL request returns a 404 despite the resource being available (I think it has to do with concurrent requests to the same server). This will make the callback fire multiple times for one download - however the success property is false for the requests that didn't work, so it's still executed once with the success flag set to true.

d.healey

@Christoph-Hart Thanks, I'll try it out :D

@d-healey
i just tried your script, the download works but the images do not appear in hise. I created 5 images (empty).

d.healey

@yall What do you mean they don't appear?

yall

in hise, it does not appear.

d.healey

@yall Show me the code you are using to display the images.

@d-healey this :) in fact I'm trying but without really understanding for the moment

@d-healey Could I use something like this for Users to download HR1 files into their native OS downloads folder?

I've had to make a separate downloader anyway which links to a website but I'd rather it just download files without using a browser

d.healey

@DanH Yes.

I think so too :)

Go read the docs and write it out from scratch then you'll understand it.

@d-healey This is super useful, I've been playing around with it but not sure it's going to work with Dropbox (or at least it hasn't really yet)... which is where my files are stored at the moment.

Also wondering if it's possible to wrap the...

Server.downloadFile("download/HISE_1_1_1.exe", {}, target, function()

in a button callback?

d.healey

It should work with dropbox as long as the URL is public.

Also wondering if it's possible to wrap the...in a button callback?

Try it and see.
