I am using your library and pretty happy, I just looking for the MUC chat can you please guide me is this library supports MUC Conversation.

Thanks

I think it makes sense to define custom equality for the JID type, because it is such a simple value object.

We need to migrate from that nasty project.json back to orthodox csproj.

JID parsing should be fixed to support nicknames with at-signs (e.g. nick@name).

Hi,

I am using Xamarin Forms and recently updated with latest Nuget package, it works fine in simulator but on connection it is crashing when I run on physical device.

Thanks

Hello,

For XmppComponent, the spec requires that the To field be the component name.
( to="componentname.domain" )

Could XmppTcpConnection be modified to use this format when connecting with the 'jabber:component:accept' namespace?

Hi,

I am able to use this library in simulator but on physical device I am getting the following error.

List of configured name servers must not be empty.

Hi,

Using presence event handler I am able to get the realtime present of my friends those who attached to my roaster.
Now I can see the presence xml but little bit confuse how can I can easily fetch the Presence modes.
There is different xml for different modes likewise "Available , offline , away".
Following are all three types of presence xml. Just needed help is there any best approach is there to retrieve the presence from xml quickly or I need to parse/process the xml.

Available

Readme should describe the library purpose, capabilities, and proposed usage.

The library should periodically build on Travis and Appveyor.

    var username = "3111";
        var password = "3111";

var Client = new XmppClient
(new JID($"{username}@blah.com"), password, true);
Client.ConnectAsync();

        bookmarkedConference.SetAttributeValue("JID", "[email protected]");
        bookmarkedConference.SetAttributeValue("Nick", "John");

Hi,

I am using this library and pretty happy. Now I am looking to get information about the message delivery.
Is there any way I can track the message delivery information.

Thanks

Existing XmppWebSocketConnection.cs was made before RFC7395 was released and needs to change framing namespace to "urn:ietf:params:xml:ns:xmpp-framing"

Hi, this issue concerns a few things:

1. Is there a way to disconnect an existing XMPPWebSocketConnection or XmppTcpConnection and reopen them later? I don't see methods exposing some of these.
2. XMPPWebSocketConnection does not override Dispose to dispose the WebSocket object. This may result in memory leaks.

Hi,

I am looking to catch the ConnectionFailed Event but it does work as I expected.
I am using this library in my chat app using Xamarin Forms, It is working perfectly fine.
I noticed that when app at background for sometime so app disconnect from the xmpp server.
Now I wanted to know is there any way I can check the XmppClient connection state so that would help me see the connection state of the XmppClient to achieve the desired task.

Thanks

1. Create new .NET Core project.
2. Install SharpXMPP.Shared:

   <PackageReference Include="SharpXMPP.Shared" Version="0.0.1-pre02" />

3. Write the following code:

   var x = new XMPPMessage();
   x.Text = "hello world";

4. When ran, it will throw the following exception:

   System.ArgumentException: An XObject cannot be used as a value.
      at System.Xml.Linq.XContainer.GetStringValue(Object value)
      at System.Xml.Linq.XElement.SetValue(Object value)
      at SharpXMPP.XMPP.Client.Elements.XMPPMessage.set_Text(String value)
   

We have a nice api XmppTcpConnection::ConnectAsync(CancellationToken), but the token is completely ignored there.

This breaks an ability to cancel the connection.

Currently SharpXMPP may not work properly with non-ASCII symbols in JIDs and passwords, they should be normalised as described in RFC7564

We need to specify authors, license, etc. in our nuspec file.

For example, I'm trying to connect as [email protected], and it unfortunately tells me:

System.ArgumentException: None of the discovered or specified addresses match the socket address family.
Parameter name: addresses
   at System.Net.Sockets.Socket.BeginConnect(IPAddress[] addresses, Int32 port, AsyncCallback requestCallback, Object state)

   at System.Net.Sockets.TcpClient.ConnectAsyncCore(IPAddress[] addresses, Int32 port)
   at SharpXMPP.XmppTcpConnection.<Connect>d__15.MoveNext()

We need to set up NuGet publishing infrastructure and maybe even publish the first preview release.

Hi,

var roast = client.RosterManager.Roster;

Even at backend I have two friends in roster but this method always return 0
Secondly is there any way I can catch the roaster updates.

Thanks

Hi,

Please guys help me how can I do FileUploading.

Where can I find a simple example of creating a message to send?

SharpXMPP.XMPP.JID servjid = new SharpXMPP.XMPP.JID()
{
    User = user, Domain = server, Resource = Environment.MachineName
};

var xmppClient = new SharpXMPP.XmppClient(servjid, pass, false);

// Do I have to create the XML or is there methods to do it?
xmppClient.sxmppClient.Send(?????????);

Hi,

I am using ejabberd with this client library in Xamarin Forms and pretty happy so far.
I am looking for File upload but this feature is not available in library. Can you please help me out or if any resources which are helpful so please share with me.
I have configured Rest api of ejabberd but not able to find the file upload api.
Please guide me is there any resource that help me to achieve this behavior.

Thanks

Hi, does SharpXMPP support the BOSH (Bi-directional streams Over Synchronous HTTP) XMPP extension? One use for this is Open Streaming Platform (OSP)'s chat, which uses XMPP/BOSH, and it would awesome to be able to use this library to connect a bot to the chat. Thank you!

Hi.

What's the use of Capabilities why does it creates a Node http://bggg.net.ru/caps ?

Code from SharpXMPP.Shared/XmppConnection.cs

protected XmppConnection(string ns)
{
    queries = new Dictionary<string, Action<XMPPIq>>();
    _ns = ns;
    Capabilities = new CapabilitiesManager
    {
        Identity = new Identity
        {
            Category = "client",
            IdentityType = "mobile",
            IdentityName = "SharpXMPP"
        },

        Node = "http://bggg.net.ru/caps",
        Features = new List<string>
        {
            Namespaces.DiscoInfo,
            Namespaces.DiscoItems
        }
    };

    IqManager = new IqManager
    {
        PayloadHandlers =
        {
            new InfoHandler(Capabilities),
            new ItemsHandler()
        }
    };
    Iq += IqManager.Handle;
}

Hi all,

I'm new for Xamarin chat app. I find a function in this project. How to use XmppRegisterHandler.cs to register a new account ? Also need add/remove roster, thanks.

Currently the compilation of XmppSocketConnection class is disabled. I had to disable it in scope of .NET Core porting, because it uses WebSocket4Net, but there's no WebSocket4Net dependency in the project and I had no time to address that properly.

What should we do now? There's an issue #6. @vitalyster, do you have plans to revive this class in its scope?

It is possible to have a XEPs and RFCs support page with version (XEP-XXXX v1.2)?

Say I want to add a custom IQ handler (e.g. for XMPP Ping or whatever).

Currently, we offer no way for the user to add such handler, since we recreate the IQManager every time we need to handle an IQ query, and it is no ability to override it from the user side:

1. Connect to an XMPP server
2. Shut down the server (Prosody in my case)
3. The server will properly close the XML stream
4. But the client won't detect it

The reason is in this line of code:

Prosody closes the XML correctly, thus it will just start returning false in loop instead of trying to read more from the stream and failing.

Hi.,

I am looking to add some custom fields into XMPPMessage. Its pretty simple to modify the project and add custom fields but is there any way out there to add custom field with the existing XMPPMessage class and use it without modifying the code. Or is there any possibility to send message by setting custom attributes and process the attribute value on receiving end.
Like this

        var message = new XMPPMessages
        {   
            ID=Guid.NewGuid().ToString(),
            Text = "Hi",
            To = new JID("[email protected]")
        };
        message.SetAttributeValue("type", "Urgent");
      Client.Send(message)

Could you please add a License file to the project?

Hi

I am using ejabberd server and connecting through the static ip of the server , It is working fine in windows and console apps but on Xamarin forms I am not able to even connect both in android and iOS.
