如何在WCF中启用WebHTTP连接?

我正在开发一个将数据从Android手机传输到服务器的解决方案(用c/.net编写)。

我创建了一个WCF服务,并使用模拟器进行测试,一切正常。然后,当我尝试从手机(连接到家庭WiFi网络)登录时,收到以下异常消息:

org.apache.http.conn.httphostconnectexception:连接到 http://192.168.1.5:8000 拒绝

如果有人能看一下配置文件和接口,并就如何启用连接给出任何建议,我会非常感激。

Web.CONFIG:

<configuration>
  <system.web>
    <compilation debug="true"/>
  </system.web>
  <system.serviceModel>
    <bindings>
      <webHttpBinding>
        <binding name="DefaultBinding"
                 allowCookies="true"
                 bypassProxyOnLocal="true" />
      </webHttpBinding>
    </bindings>
    <behaviors>
      <endpointBehaviors>
        <behavior name="RESTFriendly">
          <webHttp/>
        </behavior>
      </endpointBehaviors>
    </behaviors>
    <services>
      <service name="RESTServer.LoginService">
        <endpoint address=""
                  behaviorConfiguration="RESTFriendly"
                  binding="webHttpBinding"
                  bindingConfiguration="DefaultBinding"
                  contract="RESTServer.ILoginService" />
      </service>
    </services>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
  </system.serviceModel>
</configuration>

接口:

[ServiceContract()]
public interface ILoginService
{
    [WebGet(ResponseFormat = WebMessageFormat.Xml, UriTemplate = "/username={username}&password={password}")]
    [OperationContract]
    Message Login(string username, string password);
}

服务实施:

public class LoginService : ILoginService
{
    public Message Login(string username, string password)
    {
        Message message = new Message();
        SQLWorks sqlWorks = new SQLWorks();
        string strSession = sqlWorks.Login(username, password);
        string strMessage;
        message.Session = strSession;
        if(strSession == "")
        {
            strMessage = "Login failed! Please check your username/password!";
        }
        else
        {
            strMessage = "Login Successful";
        }
        message.ErrorMessage = strMessage;
        return message;
    }
}
