wcf寄宿在iis上的跨域访问问题【不止是添加跨域文件】
源:http://www.cnblogs.com/lensso/archive/2011/04/26/2029360.html
当客户端为silverlight或者其它不默认支持跨域的技术时,需要为wcf手动开启跨域,详细方法如下:
首先跨域文件是必须的
ClientAccessPolicy.xml
CrossDomain.xml
<?xml version="1.0"?>
<cross-domain-policy>
<allow-access-from domain="*"/>
</cross-domain-policy>
<cross-domain-policy>
<allow-access-from domain="*"/>
</cross-domain-policy>
以上两个跨域文件需放在部署在iis上的根目录下。
服务端config配置如下:
<system.serviceModel> <behaviors> <serviceBehaviors> <behavior name="LoggerBehavior"> <serviceDebug includeExceptionDetailInFaults="true" /> <serviceMetadata httpGetEnabled="true" /> </behavior> </serviceBehaviors> </behaviors> <extensions> </extensions> <bindings> <basicHttpBinding> <binding name="UnSecureConversationBinding" closeTimeout="00:01:00" openTimeout="00:01:00" receiveTimeout="00:10:00" sendTimeout="00:01:00" allowCookies="false" bypassProxyOnLocal="false" hostNameComparisonMode="StrongWildcard" maxBufferSize="1048576" maxBufferPoolSize="2097152" maxReceivedMessageSize="1048576" messageEncoding="Text" textEncoding="utf-8" transferMode="Buffered" useDefaultWebProxy="true"> <readerQuotas maxDepth="32" maxStringContentLength="16777216" maxArrayLength="16384" maxBytesPerRead="4096" maxNameTableCharCount="16384" /> <security mode="None"></security> </binding> </basicHttpBinding> </bindings> <services> <service behaviorConfiguration="LoggerBehavior" name="eTank.OIU.Service.OIUService" > <endpoint binding="basicHttpBinding" bindingConfiguration="UnSecureConversationBinding" contract="eTank.OIU.Contract.IOIUUC" /> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/> </service> <service behaviorConfiguration="LoggerBehavior" name="eTank.OIU.Service.SMSConfigService" > <endpoint binding="basicHttpBinding" bindingConfiguration="UnSecureConversationBinding" contract="eTank.OIU.Contract.ISMSConfigUC" /> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/> </service> </services> </system.serviceModel>
以上服务器配置需要注意的地方为:
1.behavior中的<serviceMetadata httpGetEnabled="true" />是必须的;
2.binding中的安全级别设为none,如:<security mode="None"></security>;
3.每个服务添加一个元数据的终结点配置,如:<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/>;
完成以上配置以后silverlight等客户端即可以实现跨域访问wcf服务了。

今天用这种办法试了(在版本控制器外厕所),但是怎么都不行,把版本控制器中的两个一样的xml文件和web.config 文件复制过来,直接ok,感觉莫名其妙。
不知道哪里的问题,有朋友了解情况,望留言。
