Implementing a Anonymous Client with the Skype Web SDK

  • Article

This article will discuss the flow for Anonymous Meeting Join involving the client-side functionality of the Skype Web SDK.

The anonymous user can join into Skype meetings by using a meeting's URI. For Skype for Business Online, Anonymous Meeting Join is supported through the Trusted Application API. The meeting's URL is passed to the Service Application, which talks to the Trusted Application API and enables anonymous users to join the online meeting.

Prerequisites

  1. Obtain a meeting URL by scheduling an online meeting by using the Skype for Business Client or Outlook, or even programmatically using UCWA or the Trusted Application API. Please read Anonymous Meeting Scheduling for details.

  2. Develop Trusted Application API Service Applications for Skype for Business Online. Please read Developing Trusted Application API applications for Skype for Business Online for details.

  3. Bootstrap your web application to work with Skype Web SDK. Please read Bootstrapping the application Section for details.

Code Walkthrough

1. Get anonymous application token

When the user decides to join the meeting, it pings the Service Application with the meeting's url. The user gets the anonymous application token based on the meeting URL(should be in same tenant).

/* POST Request on "https://metiobank.cloudapp.net/GetAnonTokenJob".
 GetAnonTokenJob is the Service Application API that gets Token 
and Discovery Uri with meetingUrl.
*/ 

$.ajax({
        url: https://metiobank.cloudapp.net/GetAnonTokenJob,
        type: ‘post’,
        dataType: ‘text’,
        data: {
                ApplicationSessionId: [guid()],
                AllowedOrigins: [window.skypeWebApp.allowedOrigins] ,
                MeetingUrl: [meetingurl]
            }; 
});  

// Response data:

{
  “DiscoverUri”:”**”,
  “ExpireTime”:”**”,
  “TenantEndpointId”:”**”,
 “Token”:”” 
 }

2. Sign in to the Web SDK using the Anonymous Token and Discover URL in your sign-in parameters.

Sign in to the Web SDK using the following parameters and code:

// Payload to sign in from Web SDK:
                    anonmeetingsignin = {
                        name: '[AnonUser]',
                        cors: true,
                        root: { user: [DiscoverUri from above] },
                        auth: function (req, send) {
                            if (req.url != user)
                                req.headers['Authorization'] = "Bearer " + [Token from above];
 
                            return send(req);
                        }
                    };
        skypeWebApp.signInManager.signIn(anonmeetingsignin);

3. Get the conversation

The following client side JavaScript example queries the Web SDK conversation manager's collection of active conversations. The conversation at index 0 directly gives us the active conversation.

 client.conversationsManager.conversations(0)
