public object AfterReceiveRequest(ref Message request, IClientChannel     channel, InstanceContext instanceContext)
{
//here fetch Token value if exists
}
}

您可以使用“request”变量获取对请求数据的访问权限。例如您可以按如下方式检索用户名等标头值：

public object AfterReceiveRequest(ref Message request, IClientChannel channel, InstanceContext instanceContext)
    {
        var requestHeaders = (HttpRequestMessageProperty)request.Properties[HttpRequestMessageProperty.Name];
        var user = requestHeaders .Headers["Username"];

        //Way to access body. 
        MemoryStream ms = new MemoryStream();
        XmlWriter writer = XmlWriter.Create(ms);
        request.WriteMessage(writer); 
        writer.Flush();
        ms.Position = 0;
        XmlDocument xmlDoc = new XmlDocument();
        xmlDoc.Load(ms);
        //Now you have xml document object which can be used for further processing
        //Do whatever you want to do here   
        return null;
    }
