WCF 自承载 提供源码

1、WCF 简单介绍
Windows Communication Foundation(WCF)是由微软发展的一组数据通讯的应用程序开发接口,是一套通信接口。如今比较流行的SOA就能够经过WCF实现。他的功能若是非要用一个词来形容恐怕只能用“强大”,“完美”来形容。融合了remoting和webservices的强大功能,还推出了WCF配置的小工具,更加方便入手和进阶。

2、今天想说的
一、Wcf常常须要添加新功能,须要发布新功能与修改配置文件
二、须要配置的信息颇有特色(基本就是service,endpoint)
三、配置多了,真的很烦,并且一不当心要是写错了就,糟糕了
进入主题啦,咱们要说的是WCF自承载
3、WCF自承载
一、简单实现
1         ServiceHost host = new ServiceHost(typeof(Service1));
2             WSHttpBinding nb = new WSHttpBinding(SecurityMode.None);
3             host.AddServiceEndpoint(iType, nb, "http://127.0.0.1:8888/IService1");
4             host.Open();

这样就能够简单实现自承载了,现实中除了Http咱们还常常用到Http程序员

 1         //添加支持TCP协议服务
 2         private static void AddTcpServer(Type type, Type iType)
 3         {
 4             ServiceHost host = new ServiceHost(type);
 5             NetTcpBinding nb = new NetTcpBinding(SecurityMode.None);
 6             host.AddServiceEndpoint(iType, nb, string.Concat("net.tcp://", Ip, ":", TcpPort, "/", iType.Name));
 7             OpenServer(host, type.Name + "Tcp服务");
 8         }
 9         //添加支持HTTP协议服务
10         private static void AddHttpServer(Type type, Type iType)
11         {
12             ServiceHost host = new ServiceHost(type);
13             WSHttpBinding nb = new WSHttpBinding(SecurityMode.None);
14             host.AddServiceEndpoint(iType, nb, string.Concat("http://", Ip, ":", HttpPort, "/", iType.Name));
15             OpenServer(host, type.Name + "Http服务");
16         }
二、日常用较经常使用的有能够经过防火墙的HTTP协议,和效率很高的TCP
 1      private static void AddServer(Type type, Type iType)
 2         {
 3             ServiceHost host = new ServiceHost(type);
 4             NetTcpBinding nb = new NetTcpBinding(SecurityMode.None);
 5             host.AddServiceEndpoint(iType, nb, string.Concat("net.tcp://", Ip, ":", TcpPort, "/", iType.Name));
 6             host.Opening += delegate { Console.WriteLine(DateTime.Now.ToString() + "  Http服务启动中" + "\r\n"); };
 7             host.Opening += delegate { Console.WriteLine(DateTime.Now.ToString() + "  Http服务已经启动" + "\r\n"); };
 8 
 9             host.Open();
10             ServiceHost host1 = new ServiceHost(type);
11             WSHttpBinding nb1 = new WSHttpBinding(SecurityMode.None);
12             host1.AddServiceEndpoint(iType, nb1, string.Concat("http://", Ip, ":", HttpPort, "/", iType.Name));
13             host1.Opening += delegate { Console.WriteLine(DateTime.Now.ToString() + "  Http服务启动中" + "\r\n"); };
14             host1.Opening += delegate { Console.WriteLine(DateTime.Now.ToString() + "  Http服务已经启动" + "\r\n"); };
15             host1.Open();
16         }

这样已经强大了,传入服务和协定的Type,就能够实现服务在Http和Tcp上的承载了。当有一天咱们须要msmq,当有一天咱们想把服务运行状况的记录到数据库中,当...。一般需求是多变的,程序员要多给本身留点后路web

三、后路
 1         private static void AddServer(Type type, Type iType, bool useTcpHost, bool useHttpHost)
 2         {
 3             if (useTcpHost)
 4                 AddTcpServer(type, iType);
 5 
 6             if (useHttpHost)
 7                 AddHttpServer(type, iType);
 8         }
 9         //添加支持TCP协议服务
10         private static void AddTcpServer(Type type, Type iType)
11         {
12             ServiceHost host = new ServiceHost(type);
13             NetTcpBinding nb = new NetTcpBinding(SecurityMode.None);
14             host.AddServiceEndpoint(iType, nb, string.Concat("net.tcp://", Ip, ":", TcpPort, "/", iType.Name));
15             OpenServer(host, type.Name + "Tcp服务");
16         }
17         //添加支持TCP协议服务
18         private static void AddHttpServer(Type type, Type iType)
19         {
20             ServiceHost host = new ServiceHost(type);
21             WSHttpBinding nb = new WSHttpBinding(SecurityMode.None);
22             host.AddServiceEndpoint(iType, nb, string.Concat("http://", Ip, ":", HttpPort, "/", iType.Name));
23             OpenServer(host, type.Name + "Http服务");
24         }
25 
26         private static void OpenServer(ServiceHost host, string name)
27         {
28             try
29             {
30                 host.Opening += delegate { ShowMessage(name + "启动中"); };
31                 host.Opened += delegate { ShowMessage(name + "已经启动"); };
32 
33                 host.Open();
34             }
35             catch (Exception ex)
36             {
37                 ShowMessage(host.ToString() + ex.Message);
38             }
39         }
40 
41         private static void ShowMessage(string outMessage)
42         {
43             Console.WriteLine(DateTime.Now.ToString() + "  " + outMessage + "\r\n");
44         }

第一眼相同的功能代码多多了。是否是很麻烦呢?要是你以为是,那我认可我太失败了,这样以前说的问题就不用担忧了,很简单就解决了。当时新的服务老是有,老是要我改代码,从新发布也麻烦啊。下面说不改代码的办法数据库

四、不改代码的办法
 1      static void Main(string[] args)
 2         {
 3             Setup();
 4             Console.ReadLine();
 5         }
 6 
 7         private static void Setup()
 8         {
 9             string docPath = path + "\\Assembly.xml";
10             if (File.Exists(docPath))
11             {
12                 XDocument xdoc = XDocument.Load(docPath);
13                 foreach (XElement element in xdoc.Root.Element("BLLFiles").Elements())
14                 {
15                     LoadType(element.Attribute("FileName").Value);
16                 }
17             }
18         }
19 
20         private static void LoadType(string bllPath)
21         {
22             if (!File.Exists(path + "\\" + bllPath + ".dll"))
23                 return;
24 
25             Assembly bllAssembly = Assembly.LoadFile(path + "\\" + bllPath + ".dll");
26 
27             Type[] types = bllAssembly.GetTypes();
28 
29             foreach (Type type in types)
30             {
31                 Type t1 = bllAssembly.GetType(bllPath + ".I" + type.Name);
32                 if (type == null || t1 == null)
33                     continue;
34                 AddServer(type, t1, true, true);
35             }
36         }
1 Assembly.xml文件
2 <?xml version="1.0" encoding="UTF-8"?>
3 <AssemblyInfos>
4   <BLLFiles>
5     <BLLFile FileName="WcfService"/>
6   </BLLFiles>
7 </AssemblyInfos>

认可你丫的事情多,我用一个X妹儿没你要加载的Dll文件记录下。tcp

而后反射去你全部的类。而后自动加载全部有协定的类。之后有新的服务在其余dll中,我加行BLLFil,哈哈哈,在此笑过。。。。工具

 我用这样的方式实现了,一套本身的管理系统,下载 用户名1 密码 111
