如何从HTML客户端调用Websocket

How to Call Websocket from HTML Client?

本文关键字：调用 Websocket 客户端 HTML      更新时间：2023-09-26

我写了一个wcf服务与netHttpBinding绑定和托管在II8(windows server 2012)。接口如下图所示。

[ServiceContract(CallbackContract = typeof(IDuplexCallbackContract))]
public interface IHelloWebSocket
{
   [OperationContract(IsOneWay = true, Action = "*")] 
   void SayHelloDuplexReceive(string name);
}
[ServiceContract]
public interface IDuplexCallbackContract
{
    [OperationContract(IsOneWay = true, Action = "*")] 
    void SayingHelloSend(string message);
}

现在我有了如下的服务类实现…

 [ServiceBehavior(ConcurrencyMode = ConcurrencyMode.Reentrant)]
public class HelloWebSocket : IHelloWebSocket
{
    /// <summary>
    /// Call back instance called from service to client.
    /// </summary>
    IDuplexCallbackContract _callback = null;
    public HelloWebSocket()
    {
        _callback =
            OperationContext.Current.GetCallbackChannel<IDuplexCallbackContract>();
    }
    public void SayHelloDuplexReceive(string name)
    {
        _callback.SayingHelloSend("Hello " + name + " by WebSockets");
        //return "Hello " + name;
    }
}

和web配置如下…

<system.serviceModel>
     <services>
       <service name="WebSocketUndersranding.HelloWebSocket">
          <endpoint address=""
            binding="netHttpBinding"
            contract="WebSocketUndersranding.IHelloWebSocket"/>
     </service>
    </services>
     <behaviors>
          <serviceBehaviors>
              <behavior name="">
                  <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
                 <serviceDebug includeExceptionDetailInFaults="false" />
             </behavior>
         </serviceBehaviors>
     </behaviors>
      <serviceHostingEnvironment aspNetCompatibilityEnabled="true"
           multipleSiteBindingsEnabled="true" />
   </system.serviceModel>

现在我如何从HTML5客户端调用服务??

My Service URL是一个链接

我正在尝试写客户端var websocket = new websocket (uri);但是我应该在"uri"中输入什么来调用服务呢?我找不到……??

谢谢,业务
