具有自定义绑定的 Silverlight WCF 安全性

Question

我有一个 silverlight 应用程序调用许多 WCF 服务。 silver light 客户端的典型绑定如下所示：

<basicHttpBinding>
    <binding name="ClientBindingName" maxBufferSize="2147483647"
        maxReceivedMessageSize="2147483647">
        <security mode="TransportCredentialOnly" />
    </binding>
</basicHttpBinding>

与服务器绑定配对如下：

<basicHttpBinding>
    <binding name="ServerbindingName" sendTimeout="00:02:00">
        <security mode="TransportCredentialOnly">
            <transport clientCredentialType="Windows"/>
        </security>                    
    </binding>
</basicHttpBinding>

对于其中一项服务，我需要自定义绑定，但我无法找到不会导致403 错误。

我能为客户端提供的最好方案是：

<customBinding>
    <binding name="CustomBinding_IZipService_StreamedResponse" closeTimeout="00:10:00"
             openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00">
        <binaryMessageEncoding />
        <httpTransport maxReceivedMessageSize="2147483647"
                       maxBufferSize="2147483647"
                       transferMode="StreamedResponse" />
    </binding>
</customBinding>

对于服务：

<customBinding>
    <binding name="FS.SUV.Services.ZipService.customBinding"
             receiveTimeout="00:10:00" sendTimeout="00:10:00">
      <binaryMessageEncoding>
        <readerQuotas maxStringContentLength="524288000"/>
      </binaryMessageEncoding>
      <httpTransport transferMode="StreamedResponse"
                     maxBufferSize="524288000"
                     maxBufferPoolSize="524288000"
                     maxReceivedMessageSize="524288000" />
      <security authenticationMode="SecureConversation" requireSecurityContextCancellation="true">
        <secureConversationBootstrap authenticationMode="UserNameOverTransport" />
      </security>
    </binding>
  </customBinding>

我怎样才能获得自定义绑定，以便通过 Windows 身份验证与 silverlight 配合良好？

Answer 1

事实证明我想得太复杂了。客户端绑定很好，因此保留为：

<binding name="CustomBinding_IZipService_StreamedResponse" closeTimeout="00:10:00"
         openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00">
    <binaryMessageEncoding />
    <httpTransport maxReceivedMessageSize="2147483647"
                   maxBufferSize="2147483647"
                   transferMode="StreamedResponse" />
</binding>

服务器绑定需要这样设置：

<customBinding>
    <binding name="ClientBindingName"
             receiveTimeout="00:10:00" sendTimeout="00:10:00">
        <binaryMessageEncoding>
            <readerQuotas maxStringContentLength="524288000"/>
        </binaryMessageEncoding>
        <httpTransport transferMode="StreamedResponse"
                       maxBufferSize="524288000"
                       maxBufferPoolSize="524288000"
                       maxReceivedMessageSize="524288000"
                       authenticationScheme="Negotiate" />
    </binding>
</customBinding>

您的配置不正确。在两侧尝试此操作（并根据需要修改读者配额和消息大小限制）：

<customBinding>
    <binding name="CustomBinding_IZipService_StreamedResponse" closeTimeout="00:10:00"
             openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00">
        <binaryMessageEncoding />
        <httpTransport authenticationMode="Negotiate"
                       maxReceivedMessageSize="2147483647"
                       maxBufferSize="2147483647"
                       transferMode="StreamedResponse" />
    </binding>
</customBinding>
