c# - WCF wsHttpBindingwith silverlight 中的跨域错误

Question

我有一个 WCF 服务，我在 web.config 中使用 wsHttpBinding。

我还从 IIS7 创建了一个测试证书，并将其用于与网站的 https 绑定(bind)

服务的Web配置如下

<system.serviceModel>
  <behaviors>
   <serviceBehaviors>
    <behavior name="WsBehaviour">
     <serviceMetadata httpsGetEnabled="true"/>
     <serviceDebug includeExceptionDetailInFaults="false"/>
    </behavior>
   </serviceBehaviors>
  </behaviors>

  <bindings>
   <wsHttpBinding>
    <binding name="WsBinding">
      <security mode="Transport">
        <transport clientCredentialType="None" proxyCredentialType="None" realm=""/>
        <message clientCredentialType="None" algorithmSuite="Default" />        
      </security>            
    </binding>
   </wsHttpBinding>    
  </bindings>

  <services>
   <service name="WsService.Service1" behaviorConfiguration ="WsBehaviour">
     <endpoint address="https://MachineName.DomainName:8087/WsService/Service1.svc"
      binding="wsHttpBinding" bindingConfiguration="WsBinding" contract="WsService.IService1" >

       <identity>
         <dns value="localhost" />
       </identity>

     </endpoint>
   </service>
  </services>  
 </system.serviceModel>

当我在浏览器中打开 URL 时，它运行良好，当我向 silverlight 项目添加服务引用时，它也运行良好。

但是当我从应用程序调用该服务时，它会出现跨域错误。

我在项目中也包含了clientaccesspolicy.xml和crossDomain.xml，但是还是遇到了问题

An error occurred while trying to make a request to URI
'https://MachineName.DomainName:8087/WsService/Service1.svc'. This
could be due to attempting to access a service in a cross-domain way
without a proper cross-domain policy in place, or a policy that is
unsuitable for SOAP services. You may need to contact the owner of the
service to publish a cross-domain policy file and to ensure it allows
SOAP-related HTTP headers to be sent. This error may also be caused by
using internal types in the web service proxy without using the
InternalsVisibleToAttribute attribute. Please see the inner exception
for more details.

Answer 1

clientaccesspolicy.xml 需要在您的网络服务器的根目录中，而不是在您的项目中。

3.将 crossdomain.xml 文件保存到托管服务的域的根目录。例如，如果服务托管在 http://fabrikam.com 中, 那么该文件必须位于 http://fabrikam.com/crossdomain.xml
