LCS使用RTC API 发送IM消息的WebService

微软LCS 2005 With SP1 发布也有一段时间了。

1。准备工作：安装RTC Client API
        http://msdn.microsoft.com/downloads/list/clientapi.asp

	Microsoft Windows Real-Time Communications Client API SDK v1.3 The Microsoft Windows Real-Time Communications Software Development Kit 1.3 provides information, samples, and tools regarding the additional features of the Real-Time Communications 1.3 API. Additional features include: enhanced multiple points of presence support, support for Microsoft Office Live Communications Server 2005, additional client security options, and marshalling support.
	Microsoft Real-time Communications Client Software Development Kit (SDK) v1.2 The Microsoft Real-time Communications Client SDK provides documentation, sample code and other tools that allow developers to build real-time communication applications, or integrate real-time communication functionality into existing applications. Note: To execute samples or applications upon any development or test machine, install the SDK and then run RTCAPISETUP.EXE to install the Microsoft Real-time Communications Client API binaries. This executable can be found within the "Installation" sub-directory.

重要：请安装同时1.2和1.3 ，安装完下载后的MSI包之后，而且要运行
    :\Program Files\RTC Client API v1.2 SDK\INSTALLATION\RtcApiSetup.exe
    :\Program Files\RTC Client API v1.3 SDK\INSTALLATION\RtcApiSetup.exe
    :\Program Files\RTC Client API v1.3 SDK\INSTALLATION\RtcSxSPolicies.msi
   以上3个全部要安装，不是说安装1.3就不需要安装1.2了，而且要按照这个顺序，否则可能不能成功。
最好重新启动电脑吧，（把WebService发布到服务器时候记得也要在服务器上面安装哦）

2：编写Lib

using System;
using System.Collections.Generic;
using System.Text;

namespace CMS.LCSLib
{
    public class RTCClass
    {            

        private static void  createEnableProfile(RTCCORELib.RTCClient objRTCClient, string account, string password, string uri, string addr, string domain)
        {
            string s = "";
            s += "<provision key=\"{566E246F-9978-4434-83BF-3E47BCCFF466}\" name=\"" + domain + "\">";
            s += "<user account=\"" + account + "\" password=\"" + password + "\" uri=\"" + uri + "\" />";
            s += "<sipsrv addr=\"" + addr + "\" protocol=\"tcp\" role=\"proxy\">";
            s += "<session party=\"first\" type=\"pc2pc\" />";
            s += "<session party=\"first\" type=\"pc2ph\" />";
            s += "<session party=\"first\" type=\"im\" />";
            s += "</sipsrv>";
            s += "<sipsrv addr=\"" + addr + "\" protocol=\"tcp\" role=\"registrar\" />";
            s += "</provision>";
            
            RTCCORELib.IRTCProfile2 objProfile;//
            RTCCORELib.IRTCClientProvisioning2 objProvisioning;//

            try
            {
                objProvisioning = (RTCCORELib.IRTCClientProvisioning2)objRTCClient;

                objProfile = (RTCCORELib.IRTCProfile2)objProvisioning.CreateProfile(s);

                //EnableProfile
                objProvisioning.EnableProfile(objProfile, 0xF);
                //g_objProvisioning.EnableProfileEx(g_objProfile, 0x0000000F, 0x0000000F);
            }
            catch (Exception ex)
            {
                System.Diagnostics.EventLog.WriteEntry("LCSClass", ex.ToString());
            }
            return ;

        }

        public static void SendMessage(string strDestURI)
        {
            string account = @"tianchi\test";
            string password = "test";
            string uri = "sip:test@tianchi.local";
            string addr = "cms-biztalk.tianchi.local:5060";
            string domain = "tianchi.local";
            string strMsgHeader = null;
            string strMsg = "test from webservice";
            int lCookie = 0;
            string strDestName = null;

            try
            {

                  SendMessage(account, password, uri, addr, domain,
                       strMsgHeader, strMsg, lCookie, strDestURI, strDestName);
}
                  catch (Exception ex)
            {
                System.Diagnostics.EventLog.WriteEntry("LCSClass", ex.ToString());
            }

            return;
        }

        public static void SendMessage(string account, string password, string uri, string addr, string domain,
            string strMsgHeader, string strMsg, int lCookie, string strDestURI, string strDestName)
        {
            try
            {
                RTCCORELib.RTCClient objRTCClient;//            
                RTCCORELib.IRTCSession objSession;
                //RTCCORELib.IRTCParticipant g_objParticipant;

                //'RTCClient needs to be initialized before any other method can be called on it.
                objRTCClient = new RTCCORELib.RTCClient();
                objRTCClient.Initialize();

                //createProfile & EnableProfile
                createEnableProfile(objRTCClient, account, password, uri, addr, domain);

                //'Create an IM session.
                objSession = objRTCClient.CreateSession(RTCCORELib.RTC_SESSION_TYPE.RTCST_MULTIPARTY_IM, null, null, 0);

                //'Add a participant to the IM session.
                //g_objParticipant = g_objSession.AddParticipant(strDestURI, strDestName);
                objSession.AddParticipant(strDestURI, strDestName);

                //'Send a message.
                objSession.SendMessage(strMsgHeader, strMsg, lCookie);
                //g_objSession.SendMessage(null, strMsg, 0);
            }
            catch (Exception ex)
            {
                System.Diagnostics.EventLog.WriteEntry("LCSClass", ex.ToString());
            }
        }
    }
}

3：编写WebService

using System;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;

[WebService(Namespace = "http://tempuri.org/")]
[WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
public class RTCClass : System.Web.Services.WebService
{
    public RTCClass()
    {

        //Uncomment the following line if using designed components 
        //InitializeComponent(); 
    }

    [WebMethod]
    public void SendMessage(string account, string password, string uri, string addr, string domain,
            string strMsgHeader, string strMsg, int lCookie, string strDestURI, string strDestName)
    {
        CMS.LCSLib.RTCClass.SendMessage( account,  password,  uri,  addr,  domain,
             strMsgHeader,  strMsg,  lCookie,  strDestURI,  strDestName);
        return ;
    }
    /**//// <summary>
    /// 发送一个测试消息给某个用户
    /// </summary>
    /// <param name="strDestURI">格式：sip:cleo@tianchi.local</param>
    [WebMethod]
    public void SendMessageTest(string strDestURI)
    {      
        CMS.LCSLib.RTCClass.SendMessage( strDestURI);
        return;
    }
    
}

关于RTCCORELib.dll 引用问题
++++++++++++++++++++++++++++++++++++++++
在项目里面引用DLL的时候，
路径可能是：C:\WINDOWS\WinSxS\x86_Microsoft.Windows.Networking.RtcDll_6595b64144ccf1df_5.2.2.1_x-ww_d6bd8b93\RTCCORELib.dll
你在\WINDOWS\WinSxS\x86_Microsoft.Windows.Networking.RtcDll_XXXXX之类的目录里面找就可以，
你也可以搜索RTCCORELib.dll

注意在ＳＤＫ安装的时候，要关闭其它程序，尤其是Messager之类的，否则可能会造成找不到RTCCORELib.dll
