How to send commands to custom receivers?

[mesacarlos]

Hello!

I just found your project and it looks exactly tle library I needed for a project I'm developing! :)

I'm trying to cast a custom receiver to my Chromecast, and then send a JSON message to it.
An example of what I'm trying to achieve can be found here: https://github.com/boombatower/chromecast-dashboard/blob/ec6f462154590f14ec2a8fc40749357588bb1725/sender/main.js#L80

As you can see, it just connects and sends a JSON message like this:

{
    type: 'load',
    url: "https://google.com/",
    refresh: 0,
}

Trying to find a way to achieve this, I found that this library had a method called LoadUrl() used to load a webpage in the receiver, but I was unable to find that method today.

I also tried creating a custom Channel and Message, but I had no luck. Chromecast launches app correctly, but it seems that message is not being received:

Method used to launch the receiver:

private async void OnTestClick(object sender, EventArgs e)
        {
            IChromecastLocator locator = new MdnsChromecastLocator();
            var chromecasts = await locator.FindReceiversAsync();

            var chromecast = chromecasts.First();
            var client = new ChromecastClient();
            await client.ConnectChromecast(chromecast);
            await client.LaunchApplicationAsync("F7FD2183");



            //_ = await client.GetChannel<IMediaChannel>().LoadAsync(media);
            await client.GetChannel<VideochatChannel>().LoadAsync();
            //_ = await client.SendAsync("urn:x-cast:com.boombatower.chromecast-dashboard", new CustomMessage("https://mesacarlos.es/"), chromecast.)
        }

My custom channel:

internal class VideochatChannel : ChromecastChannel
    {
        /// <summary>
        /// Initializes a new instance of MediaChannel class
        /// </summary>
        public VideochatChannel() : base("urn:x-cast:com.boombatower.chromecast-dashboard")
        {
        }


        /// <summary>
        /// Loads app
        /// </summary>
        public Task LoadAsync()
        {
            var status = Client.GetChromecastStatus();
            return SendAsync(new VideochatMessage() { SessionId = status.Applications[0].SessionId, Url = "https://mesacarlos.es/" });
        }

    }

My custom message:

internal class VideochatMessage : MessageWithSession
    {
        public string Url { get; set; }

        public string Refresh { get; set; }

        public VideochatMessage()
        {
            Type = "load";
        }
    }

Is it possible to do what I'm trying to do? If so, If you could give me any advice on how to achieve it, it would be awesome!
Thank you in advance :)

Hi, problem solved!

Solved adding [DataMember(Name = "url")] and [DataMember(Name = "refresh")] to my Message class properties!
