Silverlight 4 - 配置自承载 WCF 服务以使用 SSL

Question

我有一个 Silverlight 4 应用程序，它在同一台服务器(自托管)上使用 WCF 服务。一切正常，但现在我想将我的 WCF 服务转换为使用 SSL。我正在使用 CustomBindings，但无法完全找到完成此操作的组合。我在客户端使用相对 URL，希望这不会造成问题。以下是我的 Web.config 文件的重要部分:

    <behaviors>
      <serviceBehaviors>
        <behavior name="">
          <serviceMetadata httpGetEnabled="true"  />
          <serviceDebug includeExceptionDetailInFaults="true" />
          <dataContractSerializer maxItemsInObjectGraph="6553600"/>
          <serviceTimeouts transactionTimeout="00:10:00"/>
        </behavior>
        </serviceBehaviors>
      </behaviors>

    <bindings>
      <customBinding>
        <binding name="MyApp.Web.Services.ProjectService.customBinding0"
          receiveTimeout="00:10:00" sendTimeout="00:10:00">
          <binaryMessageEncoding />
          <httpsTransport maxReceivedMessageSize="2147483647" />
        </binding>
      </customBinding>
    </bindings>
  <services>
    <service name="MyApp.Web.Services.ProjectService">
        <endpoint address="" binding="customBinding" bindingConfiguration="MyApp.Web.Services.ProjectService.customBinding0"
          contract="MyApp.Web.Services.ProjectService" />
      </service>

我的 ClientConfig 是这样的:

    <configuration>
    <system.serviceModel>
        <bindings>
            <customBinding>
                <binding name="CustomBinding_ProjectService">
                    <binaryMessageEncoding />
                    <httpTransport maxReceivedMessageSize="2147483647" maxBufferSize="2147483647" />
                </binding>
           </customBinding>
       </bindings>
       <client>
            <endpoint address="../Services/ProjectService.svc" binding="customBinding"
                bindingConfiguration="CustomBinding_ProjectService" contract="SearchProxy.ProjectService"
                name="CustomBinding_ProjectService" />
     </client>
  </system.serviceModel>
</configuration>

我只是不明白绑定(bind)在服务器和客户端中是如何工作的。我希望有人能给我指出正确的方向。

一些事情:

如果您想在本地主机上使用 SSL，则需要使用 IIS Express 7.5(如果您在服务器上进行开发，则需要使用完整的 IIS——不太可能)。

您需要一个存储在 Web 应用程序根目录中的 clientaccesspolicy.xml 文件:

<?xml version="1.0" encoding="utf-8"?>
    <access-policy>
       <cross-domain-access>
           <policy>
               <allow-from http-request-headers= "SOAPAction">
                   <domain uri="https://*"/>
               </allow-from>
               <grant-to>
                    <resource path="/" include-subpaths="true"/>
               </grant-to>
           </policy>
       </cross-domain-access>
     </access-policy>

服务器端 Web.config 示例:

<system.serviceModel>
  <bindings>
    <basicHttpBinding>
      <binding name="SecureBasicHttpBinding">
        <security mode="Transport">
          <transport clientCredentialType="Certificate" />
        </security>
      </binding>
    </basicHttpBinding>
  </bindings>

  <behaviors>
    <serviceBehaviors>
      <behavior name="SomeBehavior" >
        <serviceMetadata httpsGetEnabled="true"/>
        <serviceDebug includeExceptionDetailInFaults="true"/>
        <useRequestHeadersForMetadataAddress>
          <defaultPorts>
            <add scheme="https" port="443" />
          </defaultPorts>
        </useRequestHeadersForMetadataAddress>
      </behavior>
    </serviceBehaviors>
  </behaviors>

  <serviceHostingEnvironment>
    <serviceActivations>
      <add relativeAddress="SomeService.svc" service="MySilverlight.Web.SomeService"/>
    </serviceActivations>
  </serviceHostingEnvironment>

  <services>
    <service name="MySilverlight.Web.SomeService"
             behaviorConfiguration="SomeBehavior">

      <endpoint address="SomeService"
                binding="basicHttpBinding"
                bindingConfiguration="SecureBasicHttpBinding"
                bindingNamespace="https://MySilverlight.Web.SomeService"
                contract="MySilverlight.Web.ISomeService">
      </endpoint>

      <endpoint address="mex"
                binding="mexHttpsBinding"
                contract="IMetadataExchange" />
    </service>
  </services>
</system.serviceModel>

客户端示例:

<?xml version="1.0" encoding="utf-8"?>
   <configuration>
      <system.serviceModel>
          <bindings>
              <basicHttpBinding>
                  <binding name="BasicHttpBinding_ISomeService" maxBufferSize="2147483647"
                       maxReceivedMessageSize="2147483647">
                      <security mode="Transport" />
                  </binding>
              </basicHttpBinding>
          </bindings>
          <client>
              <endpoint address="https://localhost/SomeService.svc/SomeService"
            binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_ISomeService"
            contract="MySilverlight.Web.SomeServiceReference.ISomeService"
            name="BasicHttpBinding_ISomeService" />
         </client>
    <extensions />
    </system.serviceModel>
</configuration>

IIS 7.5 将自动设置您的本地主机证书。
