如何通过WSHttpBinding安全性和GZip压缩来构建自定义绑定？

Question

我在这里面临一个问题.我正在做一个客户端/服务器项目,这是WCF Web服务调用来获取数据.由于传输的大量数据,我必须以编程方式(而不是通过配置文件)将我的绑定更改为自定义绑定.

我正在创建一个新的用户定义绑定,也就是自定义绑定.该类的例子是:

public class MyCustomBinding : CustomBinding    

并覆盖函数BindingElementCollection:

public override BindingElementCollection CreateBindingElements()
{
   WSHttpBinding wSHttpBinding = new WSHttpBinding("RMSKeberosBinding"); //this is to load the configuration from app.config. because i want to copy the setting of wsHttpConfig to my custom binding.

   BindingElementCollection wSHttpBindingElementCollection = wSHttpBinding.CreateBindingElements();

   TransactionFlowBindingElement transactionFlowBindingElement = wSHttpBindingElementCollection.Remove<TransactionFlowBindingElement>();
   SymmetricSecurityBindingElement securityElement = wSHttpBindingElementCollection.Remove<SymmetricSecurityBindingElement>();
   MessageEncodingBindingElement textElement = wSHttpBindingElementCollection.Remove<MessageEncodingBindingElement>();
   HttpTransportBindingElement transportElement = wSHttpBindingElementCollection.Remove<HttpTransportBindingElement>();

   GZipMessageEncodingBindingElement gzipElement = new GZipMessageEncodingBindingElement(); // this is from microsoft sample. i want to add gzip as a compress to my message.

   BindingElementCollection newCol = new BindingElementCollection();
   newCol.Add(transactionFlowBindingElement);
   newCol.Add(securityElement);
   newCol.Add(gzipElement);
   newCo .Add(transElement);
   return newCol;
}

我想要做的是从wshttpbinding复制所有设置,并添加gzip作为消息编码器. 压缩加密数据将导致原始数据大小更大. 这是因为WSHttpBinding的SymmetricSecurityBindingElement进行了加密.如何以正确的方式做到这一点？我希望wshttpbinding的安全设置,以及gzip工作.

您应该能够仅使用一种行为来相应地应用压缩：

编辑：我也许还应该包含基于行为的压缩的链接：
