UCMA4中连接的建立

UCMA4初体验中说到了用UCMASampleHelper帮助建立连接，现在来看自己如何建立。

前文说到了，过程分四步：创建终端、认证终端、会话建立、连接建立。

1.UserEndpoint的构造方法只有一个：

public UserEndpoint(CollaborationPlatform platform, UserEndpointSettings settings);

 第一个参数是平台，第二个是配置。还记得UCMA对象基本都需要配置信息吗？而且一般都是第二个（最后一个）参数。我们先创建UserEndpointSettings的实例，UserEndpointSettings有四个构造方法，我们选择下面这个：

public UserEndpointSettings(string ownerUri, string serverName);

 也就是说“由谁登录，登录到哪”。然后指定它的两个属性：

using System.Net;
userEndpointSettings.AutomaticPresencePublicationEnabled = true;
userEndpointSettings.Credential = new NetworkCredential("i", "**", "ads.assk.com");

 AutomaticPresencePublicationEnabled设为true 能使对方跟踪你的状态信息。第二个是用来认证的信息，参数分别是用户名、密码、域。

然后来创建平台。CollaborationPlatform有三个构造方法：

public CollaborationPlatform(ClientPlatformSettings platformSettings);
public CollaborationPlatform(ProvisionedApplicationPlatformSettings platformSettings);
public CollaborationPlatform(ServerPlatformSettings platformSettings);

 我们传一个ClientPlatformSettings实例：

ClientPlatformSettings clientSettings = new ClientPlatformSettings("test", SipTransportType.Tls);

 SipTransportType有三个枚举值：None，Tcp，Tls。

然后终端就建好了：

UserEndpoint endPoint = new UserEndpoint(platform, userEndpointSettings);

 2.和服务器连接分两步：

endPoint.Platform.BeginStartup(CallStarttupComplete, endPoint);
endPoint.BeginEstablish(CallEstablishCompleted, endPoint);

 需要用线程信号控制一下，第一个执行完了才能执行第二个。

private void CallStarttupComplete(IAsyncResult result)
        {
            UserEndpoint userEndPoint = result.AsyncState as UserEndpoint;
            CollaborationPlatform collabPlatform = userEndPoint.Platform;
            {
                collabPlatform.EndStartup(result);
            }
        }
private void CallEstablishCompleted(IAsyncResult result)
        {
            {
                UserEndpoint messageCall = result.AsyncState as UserEndpoint;
                messageCall.EndEstablish(result);
                _callEstablishComplete.Set();
            }
        }

 3.开启会话前一篇文章说了，这里使用一下其他的构造方法：

ConversationSettings settings = new ConversationSettings();
settings.Priority = ConversationPriority.Normal;
settings.Subject = "Test 01.";
Conversation conversation = new Conversation(endPoint, settings);

 4.开始通信的连接建立也提过：

InstantMessagingCall imCall = new InstantMessagingCall(conversation);
imCall.BeginEstablish("sip:[e-mail]", null, null, CallEstablishCompleted, imCall);

 建立后才可以继续其他的操作，所以也要在这里暂停。

部分连接代码：
bool SignAndPrepare(string self, string account, string pswd)//self是你自己的邮箱，account和pswd是你的域帐号
        {
                IAsyncResult ar;
                Position = loc;
                userEndpointSettings = new UserEndpointSettings("sip:" + self);
                userEndpointSettings.AutomaticPresencePublicationEnabled = true;
                userEndpointSettings.Credential = new System.Net.NetworkCredential(account, pswd);
                ClientPlatformSettings clientSettings = new ClientPlatformSettings("test", SipTransportType.Tls);
                CollaborationPlatform platform = new CollaborationPlatform(clientSettings);
                ar = platform.BeginStartup(null, null);
                platform.EndStartup(ar);

                endPoint = new UserEndpoint(platform, userEndpointSettings);
                ar = endPoint.BeginEstablish(null, null);
                endPoint.EndEstablish(ar);
            return true;
        }
这样就登录到了服务器。然后开始找人。
void CreateAndConnect(string targetUri, UserEndpoint endPoint)//给出要连接人的地址和上一步连接时的endPoint
        {
                IAsyncResult ar;
                TargetLyncUser = "sip:" + targetUri;
                ConversationSettings settings = new ConversationSettings();
                settings.Priority = ConversationPriority.Normal;
                Conversation conversation = new Conversation(endPoint, settings);
                InstantMessagingCall imCall = new InstantMessagingCall(conversation);
                ar = imCall.BeginEstablish(TargetLyncUser, new ToastMessage("new message."), null, null, null);
                imCall.EndEstablish(ar);
         }
