为简单的WCF服务启用基本身份验证？

我有一个非常简单的WCF Web服务，客户在他们自己的IIS上托管。

客户拥有自己的客户，他们在测试环境中对其进行了测试，一切正常，直到他们禁用匿名身份验证并启用基本身份验证。一旦他们这样做，他们就开始出错：

The authentication schemes configured on the host ('Basic') do not allow those configured on the binding 'BasicHttpBinding' ('Anonymous'). Please ensure that the SecurityMode is set to Transport or TransportCredentialOnly.

那么，我需要做些什么来使基本身份验证工作？

我的网络服务的当前web.config：

<configuration>
    <system.web>
        <compilation debug="true" targetFramework="4.5" />
        <httpRuntime targetFramework="4.5" />
    </system.web>
    <system.serviceModel>
        <behaviors>
            <serviceBehaviors>
                <behavior name="">
                    <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
                    <serviceDebug includeExceptionDetailInFaults="false" />
                </behavior>
            </serviceBehaviors>
        </behaviors>
        <serviceHostingEnvironment aspNetCompatibilityEnabled="true"
            multipleSiteBindingsEnabled="true" />
    </system.serviceModel>
</configuration>

我有自己的测试客户端，我可以针对我的webservice运行。它的当前app.config：

<configuration>
    <startup>
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
    </startup>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="BasicHttpBinding_IMyServiceSvc" />
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint address="http://localhost/MyServiceSvc.svc"
                binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IMyServiceSvc"
                contract="MyServiceSvc.IMyServiceSvc"
                name="BasicHttpBinding_IMyServiceSvc" />
        </client>
    </system.serviceModel>
</configuration>

当我在本地IIS上安装服务，并针对它运行客户端时，一切正常，启用了匿名身份验证。

在IIS中打开基本身份验证以及配置客户端和服务器以使用基本身份验证需要做什么？

我当前的测试客户端代码：

public class BlackHillsCompletionSvcTest
{
    static void Main(string[] args)
    {
        using (var client = new MyServiceSvcClient())
        {
            var data = new Data
            {
                id = "1",
                description = "test data"
            };

            try
            {
                var result = client.receiveData(data);
            }
            catch (Exception ex)
            {
                var msg = ex.Message;
            }
        }
    }
}

==尝试：==

根据Pankaj Kapare的建议，我将此添加到网络服务web.config：

<system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding name="httpBinding">
                <security mode="TransportCredentialOnly">
                    <transport clientCredentialType="Basic" />
                </security>
            </binding>
        </basicHttpBinding>
    </bindings>
    ...
</system.serviceModel>

有了这个，我在创建客户端时遇到了错误：

The binding at system.serviceModel/bindings/basicHttpBinding does not have a configured binding named 'BasicHttpBinding_IMyServiceSvc'. This is an invalid value for bindingConfiguration.

所以我将其添加到客户app.config：

<system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding name="BasicHttpBinding_IMyServiceSvc">
                <security mode="TransportCredentialOnly">
                    <transport clientCredentialType="Basic" />
                </security>
            </binding>
        </basicHttpBinding>
    </bindings>
    ...
</system.serviceModel>

有了这个，我又得到了一个错误：

The username is not provided. Specify username in ClientCredentials.

所以我在客户端添加了用户名和密码：

using (var client = new MyServiceSvcClient())
{
    client.ClientCredentials.UserName.UserName = "myusername";
    client.ClientCredentials.UserName.Password = "mypassword";
    ...
}

有了这个，我又得到了一个错误：

The requested service, 'http://localhost/MyServiceSvc.svc' could not be activated.  Which got me wondering. So I loaded the .svc page in my browser, was asked to log in, and after I did, I saw this:

The authentication schemes configured on the host ('Basic') do not allow those configured on the binding 'BasicHttpBinding' ('Anonymous').  Please ensure that the SecurityMode is set to Transport or TransportCredentialOnly.  Additionally, this may be resolved by changing the authentication schemes for this application through the IIS management tool, through the ServiceHost.Authentication.AuthenticationSchemes property, in the application configuration file at the <serviceAuthenticationManager> element, by updating the ClientCredentialType property on the binding, or by adjusting the AuthenticationScheme property on the HttpTransportBindingElement.

客户所看到的是什么。

想法？

==也许解决方案？ ==

我认为可能缺少的是服务器上的服务定义，将绑定绑定到端点：

<system.serviceModel>
    <bindings>
        <basicHttpBinding>
            <binding name="httpBinding">
                <security mode="TransportCredentialOnly">
                    <transport clientCredentialType="Basic" />
                </security>
            </binding>
        </basicHttpBinding>
    </bindings>
    <services>
        <service
                name="MyServiceSvcNs.MyServiceSvc"
                behaviorConfiguration="ServiceWithMetaData"
                >
            <endpoint name="Default"
                address=""
                binding="basicHttpBinding"
                bindingConfiguration="httpBinding"
                contract="MyServiceSvcNs.IMyServiceSvc"
                />
        </service>
    </services>
    <behaviors>
        <serviceBehaviors>
            <behavior name="ServiceWithMetaData">
                <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
                <serviceDebug includeExceptionDetailInFaults="false" />
            </behavior>
        </serviceBehaviors>
    </behaviors>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true"
        multipleSiteBindingsEnabled="true" />
</system.serviceModel>

有了这个，事情似乎有效。至少乍一看。

好的，我明白了。

首先，在IIS管理器中，您需要关闭匿名身份验证，然后启用基本身份验证。这可能需要先启用基本身份验证，然后重新启动IIS管理器。这是IIS的基本内容，而不是我的问题的一部分。

然后，我们需要更改Web服务的web.config。如果你还记得，它看起来像这样：

<configuration>
    <system.web>
        <compilation debug="true" targetFramework="4.5" />
        <httpRuntime targetFramework="4.5" />
    </system.web>
    <system.serviceModel>
        <behaviors>
            <serviceBehaviors>
                <behavior name="">
                    <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
                    <serviceDebug includeExceptionDetailInFaults="false" />
                </behavior>
            </serviceBehaviors>
        </behaviors>
        <serviceHostingEnvironment aspNetCompatibilityEnabled="true"
            multipleSiteBindingsEnabled="true" />
    </system.serviceModel>
</configuration>

我们需要将其更改为：

<configuration>
    <system.web>
        <compilation debug="true" targetFramework="4.5" />
        <httpRuntime targetFramework="4.5" />
    </system.web>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="httpTransportCredentialOnlyBinding">
                    <security mode="TransportCredentialOnly">
                        <transport clientCredentialType="Basic" />
                    </security>
                </binding>
            </basicHttpBinding>
        </bindings>
        <services>
            <service
                    name="MyServiceSvcNs.MyServiceSvc"
                    behaviorConfiguration="ServiceWithMetaData"
                    >
                <endpoint name="Default"
                    address=""
                    binding="basicHttpBinding"
                    bindingConfiguration="httpTransportCredentialOnlyBinding"
                    contract="MyServiceSvcNs.IMyServiceSvc"
                    />
            </service>
        </services>
        <behaviors>
            <serviceBehaviors>
                <behavior name="ServiceWithMetaData">
                    <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />
                    <serviceDebug includeExceptionDetailInFaults="false" />
                </behavior>
            </serviceBehaviors>
        </behaviors>
        <serviceHostingEnvironment aspNetCompatibilityEnabled="true"
            multipleSiteBindingsEnabled="true" />
    </system.serviceModel>
</configuration>

我们正在做的是使用TransportCredentialOnly安全性定义basicHttpBinding。然后我们定义一个服务，使用一个使用该绑定的端点。

然后在客户端，我们有：

<configuration>
    <startup>
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
    </startup>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="BasicHttpBinding_IMyServiceSvc" />
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint address="http://localhost/MyServiceSvc.svc"
                binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IMyServiceSvc"
                contract="MyServiceSvc.IMyServiceSvc"
                name="BasicHttpBinding_IMyServiceSvc" />
        </client>
    </system.serviceModel>
</configuration>

这需要改为：

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <startup>
        <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.5" />
    </startup>
    <system.serviceModel>
        <bindings>
            <basicHttpBinding>
                <binding name="httpTransportCredentialOnlyBinding">
                    <security mode="TransportCredentialOnly">
                        <transport clientCredentialType="Basic" />
                    </security>
                </binding>
            </basicHttpBinding>
        </bindings>
        <client>
            <endpoint
                address="http://localhost/MyServiceSvc.svc"
                binding="basicHttpBinding"
                bindingConfiguration="httpTransportCredentialOnlyBinding"
                contract="MyServiceSvc.IMyServiceSvc"
                name="BasicHttpBinding_IMyServiceSvc"
                />
        </client>
    </system.serviceModel>
</configuration>

在这里，我们再次使用TransportCredentialOnly安全性创建basicHttpBinding，我们正在修改端点以使用它。

答案 1 :(得分：1)

在服务web.config中配置basicHttpBinding，如下所示

<bindings>
  <basicHttpBinding>
    <binding name="httpBinding">
      <security mode="TransportCredentialOnly">
        <transport clientCredentialType="Basic" />
      </security>
    </binding>
  </basicHttpBinding>
</bindings>
