管理方式配置終結(jié)點(diǎn)

地址格式：[基地址]/[可選的URI]

基地址格式：[傳輸協(xié)議]://[機(jī)器名或域名][:可選端口]

以管理方式配置一個(gè)終節(jié)點(diǎn)需要將終結(jié)點(diǎn)信息放到托管進(jìn)程的配置文件中。如下面的服務(wù)定義：

View Code namespace Mynamespace
{
[ServiceContract]
interface IMyContract
{。。。}
class MyService: IMyContract
{。。。}
}

管理方式配置終結(jié)點(diǎn)

<system.serviceModel>
<services>
<service name="MyNamespace.MyServices">
<endpoint
address="http://localhost:8000/MyService"
binging="wsHttpBinging"
Contract="MyNamespace.IMyContract"
/>
</service>
</services>
</system.serviceModel>

相同服務(wù)的多個(gè)終結(jié)點(diǎn)

View Code <system.serviceModel>
<endpoint
address="http://localhost:8000/MyService"
binging="wsHttpBinging"
contract="IMyContract"
/>
<endpoint
address="net.tcp://localhost:8001/MyService"
binging="netTcpBinging"
contract="IMyContract"
/>
<endpoint
address="net.tcp://localhost:8001/MyService"
binging="netTcpBinging"
contract="IMyOtherContract"
/>
</system.serviceModel>

配置綁定

使用配置文件可以為終結(jié)點(diǎn)使用的綁定進(jìn)行定制。添加bindingConfiguration屬性。它的值要與<bindings>配置節(jié)點(diǎn)中定制的綁定名一致。

服務(wù)端綁定的配置

View Code <system.serviceModel>
<services>
<service name="MyService">
<endpoint
address="net.tcp://localhost:8000/MyService"
bindingConfiguration="TransactionalTCP"
binding="netTcpBinding"
contract="IMyContract"
/>
</service>
</services>
<bindings>
<netTcpBinding>
<binding name="TransactionalTCP"
transactionFlow="true"
/>
</netTcpBinding>
</bindings>
</system.serviceModel>

編程方式配置終結(jié)點(diǎn)

?

View Code ServiceHost host = new ServiceHost(typeof(MyService));
Binding wsBinding = new WSHttpBinding();
Binding tcpBinding = new NetTcpBinding();

host.AddServiceEndpoint(typeof(IMyContract), wsBinding, "http://localhost:8000/MyService");
host.AddServiceEndpoint(typeof(IMyContract), tcpBinding, "net.tcp://localhost:8000/MyService");

host.Open();

address參數(shù)為string類型，contract參數(shù)為Type類型，binding參數(shù)為Binding抽象類的一個(gè)子類。

由宿主提供了基地址，只使用基地址

View Code Uri tcpBaseAddress = new Uri("net.tcp://localhost:8000/");
ServiceHost host = new ServiceHost(typeof(MyService), tcpBaseAddress);
Binding tcpBinding = new NetTcpBinding();
//使用基地址作為地址
host.AddServiceEndpoint(typeof(IMyContract), tcpBinding, "");
//添加相對地址
host.AddServiceEndpoint(typeof(IMyContract), tcpBinding, "MyService");
//忽略基地址
host.AddServiceEndpoint(typeof(IMyContract), tcpBinding, "net.tcp://localhost:8000/MyService");
host.Open();

綁定配置

編程方式設(shè)置綁定屬性。下面啟用事務(wù)傳播

View Code ServiceHost host = new ServiceHost(typeof(MyService), tcpBaseAddress);
NetTcpBinding tcpBinding = new NetTcpBinding();
tcpBinding.TransactionFlow = true;
host.AddServiceEndpoint(typeof(IMyContract), tcpBinding, "net.tcp://localhost:8000/MyService");
host.Open();

元數(shù)據(jù)交換

服務(wù)有兩種方案發(fā)布元數(shù)據(jù)：一種基于HTTP-GET協(xié)議；一種使用專門的終結(jié)點(diǎn)。

WCF能夠?yàn)榉?wù)提供基于HTTP-GET的元數(shù)據(jù)，要顯式的添加服務(wù)行為（Behavior）功能。

1管理方式啟用元數(shù)據(jù)交換

配置文件急用元數(shù)據(jù)交換行為

View Code <system.serviceModel>
<services>
<service name="MyService" behaviorConfiguration="MEXGET">
<host>
<baseAddresses>
<add baseAddress="http://localhost:8000/"/>
</baseAddresses>
</host>
</service>

<service name="MyOtherService" behaviorConfiguration="MEXGET">
<host>
<baseAddresses>
<add baseAddress="http://localhost:8000/"/>
</baseAddresses>
</host>
</service>
</services>

<behaviors>
<serviceBehaviors>
<behavior name="MEXGET">
<serviceMetadata httpGetEnabled="true"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>

2編程方式啟用元數(shù)據(jù)交換

啟用元數(shù)據(jù)交換行為

View Code ServiceHost host = new ServiceHost(typeof(MyService));

ServiceMetadataBehavior behavior = host.Description.Behaviors.Find<ServiceMetadataBehavior>();
if (behavior == null)
{
behavior = new ServiceMetadataBehavior();
behavior.HttpGetEnabled = true;
host.Description.Behaviors.Add(behavior);
}
host.Open();

元數(shù)據(jù)交換終結(jié)點(diǎn)

HTTP-GET發(fā)布元數(shù)據(jù)僅是WCF一特性，并不保證交互的其他平臺(tái)會(huì)支持。發(fā)布標(biāo)準(zhǔn)方式，通過稱之為元數(shù)據(jù)交換終結(jié)點(diǎn)（MEX）發(fā)布。

三個(gè)MEX終結(jié)點(diǎn)，分別基于HTTP、TCP和IPC。第一個(gè)使用絕對地址，后兩個(gè)使用相對地址。

View Code <system.serviceModel>
<services>
<service name="MyService" behaviorConfiguration="MEX">
<host>
<baseAddresses>
<add baseAddress="net.tcp://localhost:8001/"/>
<add baseAddress="net.pipe://localhost/"/>
</baseAddresses>
</host>
<endpoint
address="MEX"
binding="mexTcpBinding"
contract="IMetadataExchang"
/>
<endpoint
address="MEX"
binding="mexNamePipeBinding"
contract="IMetadataExchang"
/>
<endpoint
address="http://localhost:8000/MEX"
binding="mexHttpBinding"
contract="IMetadataExchang"
/>
</service>
</services>
<behaviors>
<serviceBehaviors>
<behavior name="MEX">
<serviceMetadata/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>

編程方式添加MEX終結(jié)點(diǎn)

View Code BindingElement bindingElement = new TcpTransportBindingElement();
CustomBinding binding = new CustomBinding(bindingElement);

Uri tcpBaseAddress = new Uri("net.tcp://localhost:9000/");
ServiceHost host = new ServiceHost(typeof(MyService), tcpBaseAddress);

ServiceMetadataBehavior behavior = host.Description.Behaviors.Find<ServiceMetadataBehavior>();
if (behavior == null)
{
behavior = new ServiceMetadataBehavior();
host.Description.Behaviors.Add(behavior);
}
host.AddServiceEndpoint(typeof(IMetadataExchange), binding, "MEX");
host.Open();

客戶端編程

管理方式配置客戶端

客戶端需要知道服務(wù)的位置與服務(wù)相同的綁定還要導(dǎo)入服務(wù)的七月定義。配置文件如下：

View Code <system.serviceModel>
<client>
<endpoint name="MyEndpoint"
address="http://localhost:8000/MyService"
binding="wsHttpBiding"
contract="IMyContract"
/>
</client>
</system.serviceModel>

綁定配置

View Code <system.serviceModel>
<client>
<endpoint name="FirstEndpoint"
address="net.tcp://localhost:8000/MyService"
behaviorConfiguration="TransactionTCP"
binding="netTcpBiding"
contract="IMyContract"
/>
</client>
<bindings>
<netTcpBinding>
<binding name="TransactionTCP"
transactionFlow="true"
/>
</netTcpBinding>
</bindings>
</system.serviceModel>

調(diào)用超時(shí)

View Code <system.serviceModel>
<client>
<endpoint name="FirstEndpoint"
. . . .
behaviorConfiguration="LongTimeout"
binding="wsHttpBinding"
. . . .
/>
</client>
<bindings>
<wsHttpBinding>
<binding name="LongTimeout" sendTimeout="00:05:00" />
</wsHttpBinding>
</bindings>
</system.serviceModel>

Address是什么？

一個(gè)要和服務(wù)端通訊癿客戶端要做癿第一件事情，就是搞清數(shù)據(jù)要収給誰？目癿地在哪？而Address正是通過一個(gè)Uri 來唯一標(biāo)示一個(gè)WCF 癿終節(jié)點(diǎn)（EndPoint）癿，它標(biāo)示了消息収送癿目癿地。在WCF 數(shù)據(jù)通訊中，它解決了服務(wù)在哪里癿問題。

如何在配置文件中指定 Address?

在配置文件中，有兩種方弅可以挃定 Address，一種是絕對地址方弅，另外是相對地址方弅，凾刪如下：

絕對地址???
?<host>
????????? <baseAddresses>
??????????? <add baseAddress = "http://localhost:8731/" />
????????? </baseAddresses>
?? </host>
?? <endpoint address ="http://localhost:8731/Service" binding="basicHttpBindi
ng" contract="Wcf_Address_Config.IService1"> </endpoint>

相對地址???
?<host>
????????? <baseAddresses>
??????????? <add baseAddress = "http://localhost:8731/" />
????????? </baseAddresses>
? </host>
? <endpoint address ="Service1" binding="basicHttpBinding" contract="Wcf_A
ddress_Config.IService1"></endpoint>
