c# - 具有自定义 MembershipProvider 且没有 X.509 证书的 WCF，可能吗？

Question

我想根据自定义成员资格和角色提供者对 WCF 服务的用户进行身份验证，但我不想必须使用证书来保护两者之间的流量。

是否可以使用 basicHttpBinding，在没有证书的情况下传递自定义凭据？

我之所以问，是因为我有一个 WCF 服务，所有成员(member)提供程序管道等都通过配置连接并托管在 IIS 下，但用户详细信息没有传递到 IIS。

我有一个网络安全的 WAN，所以我不担心消息加密。

已开启ASP.Net兼容，配置如下。都是 .Net 4.0；

<?xml version="1.0"?>
<configuration>
<system.web>
<compilation debug="true" targetFramework="4.0" />
<membership defaultProvider="DemoMembershipProvider" userIsOnlineTimeWindow="15">
  <providers>
    <clear />
    <add name="DemoMembershipProvider" type="DemoMembershipProvider" connectionStringName="SqlConn" applicationName="TestProvider" enablePasswordRetrieval="false" enablePasswordReset="false" requiresQuestionAndAnswer="false" requiresUniqueEmail="true" passwordFormat="Clear" />
  </providers>
</membership>
<roleManager enabled="true" defaultProvider="DemoRoleProvider" >
  <providers>
    <clear/>
    <add name="DemoRoleProvider" connectionStringName="blah" applicationName="TestProvider" type="DemoRoleProvider" />
  </providers>
</roleManager>
<customErrors mode="Off" />
</system.web>
<system.serviceModel>
<services>
  <service name="DataService">
    <endpoint address="" binding="basicHttpBinding" bindingConfiguration="BindingConfiguration" contract="IDataService" />
    <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
  </service>
</services>
<bindings>
  <basicHttpBinding>
    <binding name="BindingConfiguration">
      <security mode="None">
        <message clientCredentialType="UserName"/>
      </security>
    </binding>
  </basicHttpBinding>
</bindings>
<behaviors>
  <serviceBehaviors>
    <behavior>
      <serviceMetadata httpGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="true" />
      <serviceCredentials>
        <userNameAuthentication userNamePasswordValidationMode="MembershipProvider" membershipProviderName="DemoMembershipProvider" />
      </serviceCredentials>
      <serviceAuthorization principalPermissionMode="UseAspNetRoles" roleProviderName="DemoRoleProvider" />
    </behavior>
  </serviceBehaviors>
</behaviors>
<serviceHostingEnvironment multipleSiteBindingsEnabled="true" aspNetCompatibilityEnabled="true" />
</system.serviceModel>
<system.webServer>
  <modules runAllManagedModulesForAllRequests="true"/>
</system.webServer>
</configuration>

客户端代码为；

            Console.WriteLine("Calling with valid credentials");
        using (var y = new DataServiceRef.DataServiceClient())
        {
            y.ClientCredentials.UserName.UserName = "ryan";
            y.ClientCredentials.UserName.Password = "password";
            Console.WriteLine("Result: {0}", y.GetData("blah"));
        }

您必须使用自定义绑定(bind)，因为默认绑定(bind)不支持在没有安全通道(传输或消息安全都需要证书)的情况下发送用户名和密码。使用此自定义绑定(bind):

<customBinding>
  <binding name="UsernamePasswordOverHttp">
    <textMessageEncoding messageVersion="Soap11" />
    <security
      authenticationMode="UserNameOverTransport"
      messageSecurityVersion="WSSecurity10WSTrustFebruary2005WSSecureConversationFebruary2005WSSecurityPolicy11BasicSecurityProfile10"
      allowInsecureTransport="true" />
    <httpTransport />
  </binding>
</customBinding>

另一个解决方案是使用 ClearUserNameBinding .
