Question

我正在尝试使用BasicHttpBinding和使用用户名/密码进行身份验证来设置WCF Web服务。我做了自定义身份验证类。但是，它永远不会被调用（通过调试验证）。这是我的web.config：

  <system.serviceModel>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
<behaviors>
  <serviceBehaviors>
    <behavior>
      <serviceCredentials>
        <userNameAuthentication userNamePasswordValidationMode="Custom" customUserNamePasswordValidatorType="Compareware_WebApp.webservices.AuthenticationValidator, Compareware_WebApp" />
      </serviceCredentials>
      <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
      <serviceDebug includeExceptionDetailInFaults="false" />
    </behavior>
  </serviceBehaviors>
</behaviors>
<bindings>
  <basicHttpBinding>
    <binding name="BasicHttpBinding">
      <security mode="TransportCredentialOnly">
        <message clientCredentialType="UserName" />
      </security>
    </binding>
  </basicHttpBinding>
</bindings>
<services>
  <service name="Compareware_WebApp.webservices.Accounts">
    <endpoint address="/webservices/Accounts.svc" binding="basicHttpBinding"
      bindingConfiguration="BasicHttpBinding" name="BasicEndpoint"
      contract="Compareware_WebApp.webservices.IAccounts" />
  </service>
</services>
<client />

这是我的身份验证类：

namespace Compareware_WebApp.webservices

{

public class AuthenticationValidator : UserNamePasswordValidator
{
    public override void Validate(string userName, string password)
    {
        if (null == userName || null == password)
        {
            throw new ArgumentNullException();
        }

        if (!Membership.ValidateUser(userName, password))
        {
            // This throws an informative fault to the client.
            throw new FaultException("Unknown Username or Incorrect Password");
        }
    }
}

}

我做错了什么？

Answer 1

我也遇到了这个问题，我得到了解决方案。如果您想调用Validate的{{1}}方法，那么您必须使用UserNamePasswordValidator安全性。

注意：您必须在IIS服务器上托管WCF服务，并且必须为您的网站启用SSL，否则它将无效。如果我们使用TransportWithMessageCredential而不是我们的网站启用SSL。

WCF服务器Web.config文件

TransportWithMessageCredential

服务身份验证类

<?xml version="1.0"?>
<configuration>
  <startup>
    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5"/>
  </startup>

          <serviceCredentials>

      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
  <system.web>
    <compilation debug="true"/>
  </system.web>

WCF客户端app.config文件

 public class ServiceAuthanticator : UserNamePasswordValidator
    {
        /// <summary>
        /// 
        /// </summary>
        /// <param name="userName"></param>
        /// <param name="password"></param>
        public override void Validate(string userName, string password)
        {
            if (String.IsNullOrEmpty(userName) || String.IsNullOrEmpty(password))
            {
                throw new FaultException("Please, Provide the username and password!!!");
            }

            if (userName != "abc" || password != "abc")
            {
                throw new FaultException("Sorry, Invalid username or password!!!");
            }
        }
    }

调用WCF服务的客户端程序

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup> 
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />

    <system.serviceModel>
        <bindings>
            <wsHttpBinding>
                <binding name="WSHttpBinding_IService1">
                    <security mode="TransportWithMessageCredential">
                        <transport clientCredentialType="None" />
                        <message clientCredentialType="UserName" />
                    </security>
                </binding>
            </wsHttpBinding>
        </bindings>
        <client>
            <endpoint address="https://kalpesh-pc/WCFAuth/Service1.svc" binding="wsHttpBinding"

Answer 2

据我了解，

传输需要HTTPS加密凭据，如果没有SSL，则会引发异常。 TransportCredentialOnly将以纯文本形式发送凭据，并且未加密，建议仅用于测试。因此，您的凭据是通过传输发送的。因此必须调整<Transport>标签，而不是<Message>。

以下对我有用：

<security mode="TransportCredentialOnly">
    <transport clientCredentialType="Basic"/>
</security>

自定义UserNamePasswordValidator未调用
