Installation

📦 NuGet or dotnet add package JDownloader.NET

Usage

JDownloader Setup

Before using the library, you will need to register for a MyJDownloader account and to setup JDownloader for remote API access.

1. Register for a MyJDownloader account if you don't already have one.
2. In JDownloader, navigate to Settings > MyJDownloader > Setup & Login.
3. Enter you email, password, set a device name and click Connect.
4. Verify that the Connection established. Great! message appears.

Library Setup

All JDownloader.NET functionality is exposed through the JDownloaderClient class.

Start by create an instance of this class by passing a JDownloaderClientOptions instance and a unique application key:

using JDownloader;
using JDownloader.Model;

// Setup the client
JDownloaderClient jDownloaderClient = new(new JDownloaderClientOptions
{
    AppKey = "MyAppKey"
});

Next you need to connect to your MyJDownloader account:

await jDownloaderClient.Connect("Email", "Password");

You can verify that the connection was successful using the IsConnected property of JDownloaderClient. Once connected to your MyJDownloader account, you will need to set the working device, the device that the API will connect and work with. You can query for all connected devices and find the one with the device name you configured earlier:

// Get a list of connected devices
DeviceList deviceList = await jDownloaderClient.ListDevices();

// Get the target device
DeviceData? targetDevice = deviceList.Devices.Find(d => d.Name == "MyDeviceName");

// If the device exists, set it as working device
if (targetDevice != null)
{
    jDownloaderClient.SetWorkingDevice(targetDevice);
}

You are now connected to your JDownloader running on your computer. Before you start using the available APIs, you may optionally setup a direct connection to the device, instead of going through the MyJDownloader servers:

// Get a list of direct connections
DirectConnectionInfos directConnectionInfo = await jDownloaderClient.Device.GetDirectConnectionInfos();

// If any direction connections exist, connect to the first one
if (directConnectionInfo.Infos.Count > 0)
{
    jDownloaderClient.SetDirectConnectionInfo(directConnectionInfo.Infos[0]);
}

If the direct connection fails, the JDownloaderClient automatically falls back to using MyJDownloader's servers. You are now ready to start using the available namespaces and APIs. For example, you may use the Device namespace and the Ping API to ping your JDownloader:

await jDownloaderClient.Device.Ping();

Once you're done, you may disconnect the session:

await jDownloaderClient.Disconnect();
