Wcf配置系列1－－basicHttpBinding

本篇开始讲述Wcf配置系统（本系列将以微软提供案例来验证），绑定是Wcf中的重要配置，绑定可指定在与终结点通话时所使用的通信机制，并指示如何连接到终结点。

绑定包含以下元素：
协议堆栈确定用于发送到终结点的消息的安全性、可靠性和上下文流设置。
传输确定将消息发送到终结点时使用的基础传输协议，例如 TCP 或 HTTP。
编码确定用于发送到终结点的消息的网络编码，例如，文本/XML、二进制或消息传输优化机制 (MTOM)。

Wcf框架内置了以下多种绑定：

BasicHttpBinding
WSHttpBinding
WSDualHttpBinding
WSFederationHttpBinding
NetTcpBinding
NetNamedPipeBinding
NetMsmqBinding
NetPeerTcpBinding
MsmqIntegrationBinding
BasicHttpContextBinding
NetTcpContextBinding
WSHttpContextBinding

如果系统内置的绑定不能满足要求，可以自定义绑定来进行更灵活的配置，本篇文章介绍BasicHttpBinding。

先看服务器端的配置（web.config):

<system.serviceModel>
<bindings>
<!-- Following is the expanded configuration section for a BasicHttpBinding.
Each property is configured with the default value.
See the TransportSecurity, and MessageSecurity samples in the
Basic directory to learn how to configure these features. -->
<basicHttpBinding>
<binding closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="65536" maxBufferPoolSize="524288" maxReceivedMessageSize="65536" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true">
<security mode="None"/>
</binding>
</basicHttpBinding>
</bindings>
<!--For debugging purposes set the includeExceptionDetailInFaults attribute to true-->
<behaviors>
<serviceBehaviors>
<behavior>
<serviceMetadata httpGetEnabled="True"/>
<serviceDebug includeExceptionDetailInFaults="False"/>
</behavior>
</serviceBehaviors>
</behaviors>
</system.serviceModel>如果只是使用basicHttpBinding的默认行为，则在配置文件中只需要定义binding 节点即可，如果需要自定义basicHttpBinding并且要改变一些设置。则需要定义一个命令的binding配置，并且相应服务的endpoint节点 必须通过bindingConfiguration 属性指向此binding的名称。则相应配置可能如下所示：

<services>
<service
type="Microsoft.ServiceModel.Samples.CalculatorService"
behaviorConfiguration="CalculatorServiceBehavior">
<endpoint address=""
binding="basicHttpBinding"
bindingConfiguration="Binding1"
contract="Microsoft.ServiceModel.Samples.ICalculator" />
</service>
</services>在上面的示例中，bindingConfiguration命名为

"Binding1"

，binding配置代码如下：

<bindings>
<basicHttpBinding>
<binding name="Binding1"
hostNameComparisonMode="StrongWildcard"
receiveTimeout="00:10:00"
sendTimeout="00:10:00"
openTimeout="00:10:00"
closeTimeout="00:10:00"
maxMessageSize="65536"
maxBufferSize="65536"
maxBufferPoolSize="524288"
transferMode="Buffered"
messageEncoding="Text"
textEncoding="utf-8"
bypassProxyOnLocal="false"
useDefaultWebProxy="true" >
<security mode="None" />
</binding>
</basicHttpBinding>
</bindings>

客户端配置：

<system.serviceModel>

<client>
<endpoint name="" address="http://localhost:3066/service.svc" binding="basicHttpBinding" bindingConfiguration="Binding1" contract="Microsoft.Samples.Http.ICalculator"/>
</client>

<bindings>
<basicHttpBinding>
<!-- See this sample's service configuration for the expanded
configuration section for a basicHttpBinding. The client binding
configuration also has an allowCookies setting which is false by default
-->
<binding name="Binding1" allowCookies="false"/>
</basicHttpBinding>
</bindings>

</system.serviceModel>
