How to update the headers? about pusher-websocket-dotnet

[DubMatrix]

Just create your own implementation of interface IAuthorizer (you can use HttpAuthorizer as a start). Then just add anything you like to the Authorize() function, like:

public class MyAuthorizer : IAuthorizer
{
    private Uri _authEndpoint;
    public MyAuthorizer (string authEndpoint)
    {
        _authEndpoint = new Uri(authEndpoint);
    }

    public string Authorize(string channelName, string socketId)
    {
        string authToken = null;

        using (var webClient = new System.Net.WebClient())
        {
            string data = String.Format("channel_name={0}&socket_id={1}", channelName, socketId);
            webClient.Headers[HttpRequestHeader.ContentType] = "application/x-www-form-urlencoded";
            webClient.Headers[HttpRequestHeader.Accept] = "application/json";
            webClient.Headers[HttpRequestHeader.Authorization] = "my_auth_code";
            authToken = webClient.UploadString(_authEndpoint, "POST", data);
        }
        return authToken;
    }
}
