C#验证两个Web应用程序之间的Web服务时出现问题

在中央web应用程序中,我有这段代码;

var clientUri = "http://website.localhost/Services/Info.svc/account";
var uri = new Uri(clientUri);
var networkCredentials = new NetworkCredential(_configuration.ServiceUserName, _configuration.ServicePassword);
var httpClient = new HttpClient();

httpClient.DefaultHeaders.Authorization = Credential.CreateBasic(_configuration.ServiceUserName,                                                                                   _configuration.ServicePassword);
httpClient.TransportSettings.PreAuthenticate = true;

HttpResponseMessage respone = httpClient.Get(uri);
HttpContent content = respone.Content;

在另一个应用程序的webservice中(信息.svc),我在服务的构造函数中有以下代码。

var validator = new UserNamePasswordValidator();
var cred = System.Net.CredentialCache.DefaultCredentials; //this one is empty, maybe a solution?
validator.Validate("Username", "Password");

if (!HttpContext.Current.User.Identity.IsAuthenticated)
{
//This throws a 401 unauthorize, which is shown as a 500 error in the central application
throw new WebProtocolException(HttpStatusCode.Unauthorized, "You must be authorized to perform this action.", null);
}
else
{
_userIsAbleToUseService = true;
}

我不想在validate函数中使用用户名和密码,而是使用从其他webservice发送的网络凭据,这可以实现吗?怎么做?欢迎您提出其他建议!我现在可以在validate函数中对密码进行harcode,但这不是我想要的。

<authorization>
            <allow roles="administrators"/>
            <deny roles="datareaders"/>
            <deny users="?"/>
        </authorization>

<authentication mode="Forms">
            <forms loginUrl="~/Logon/Logon" timeout="2880"/>
        </authentication>
        <membership>
            <providers>
                <clear/>
                <add name="AspNetSqlMembershipProvider" type="System.Web.Security.SqlMembershipProvider, System.Web, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" connectionStringName="ApplicationServices" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false" passwordFormat="Hashed" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" passwordStrengthRegularExpression="" applicationName="CentralApplication"/>

        </membership>

这部分是给web.config文件在第二个webapplication中

<authentication mode="Forms">
      <forms name="AllPages" loginUrl="~/Logon/" timeout="360" enableCrossAppRedirects="false" />
    </authentication>
    <authorization>
      <!-- NOTE: See Web.config under Private folder for specifics on secure pages. -->
      <deny users="?" />
    </authorization>

<membership defaultProvider="NHMembershipProvider">
      <providers>
        <clear />
        <add name="NHMembershipProvider" applicationName="Website" type="Website.Security.Authentication.Membership.CmsMembershipProvider" description="Stores and retrieves membership data from SQL server using Nhibernate" connectionStringName="NHibernate" enablePasswordRetrieval="true" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="true" passwordFormat="Hashed" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" passwordStrengthRegularExpression="" />
      </providers>
    </membership>
    <roleManager enabled="true" defaultProvider="NHRoleProvider">
      <providers>
        <clear />
        <add name="NHRoleProvider" applicationName="Website" type="Website.Security.Authentication.Membership.CmsRoleProvider" />
      </providers>
    </roleManager>
