c# - WP8 应用程序中具有 WCF 服务的凭据

Question

我有一个要在 Windows Phone 8 应用程序中使用的 WCF SOAP Web 服务。

这是我的服务的 web.config :

  <?xml version="1.0" encoding="utf-8"?>
<configuration>

  <system.web>
    <compilation debug="true" targetFramework="4.0" />
  </system.web>
  <system.serviceModel>
    <bindings>
      <basicHttpBinding>
        <binding name="ersteinb">
          <security mode="TransportWithMessageCredential"/>
        </binding>
      </basicHttpBinding>
    </bindings>
    <client>
      <endpoint contract="PDAErsteinService.IPDAErsteinMobileService" binding="basicHttpBinding" bindingConfiguration="ersteinb" name="PDAErsteinMobileServiceEndPoint"/>
    </client>
    <behaviors>
      <serviceBehaviors>
        <behavior> 
          <!-- Pour éviter la divulgation des informations sur les métadonnées, définissez la valeur ci-dessous sur false et supprimez le point de terminaison des métadonnées ci-dessus avant le déploiement. -->
          <serviceMetadata httpGetEnabled="true"/>
          <!-- Pour recevoir les détails d'exception des erreurs à des fins de débogage, définissez la valeur ci-dessous sur true. Définissez-la sur false avant le déploiement pour éviter la divulgation des informations d'exception. -->
          <serviceDebug includeExceptionDetailInFaults="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
 <system.webServer>
    <modules runAllManagedModulesForAllRequests="true"/>
  </system.webServer>

</configuration>

我需要在调用我的服务时发送凭据，因为他在反向代理下。

我找不到除此之外的其他方法来使用凭据调用我的服务:

PDAErsteinMobileServiceClient client = new PDAErsteinMobileServiceClient();
client.clientCredentials.UserName.UserName = "foo";
client.clientCredentials.UserName.Password = "foofoo";
client.GetAttelageCollectionCompleted += client_GetAttelageCollectionCompleted;
client.GetAttelageCollectionAsync();

使用这种方法，我得到了这样的异常:

System.ServiceModel.ProtocolException exception was not handled by user HResult code = 2146233087 Message = The remote server returned an unexpected response: (401) Authorization Required. In Silverlight, a 404 response code may be reported even when the service sends a different error code. Source = System.ServiceModel StackTrace: [...]

我确定我的凭据没问题，但我很确定我没有以正确的方式发送它们。如果不是那样，那可能是我在 web.config 中的安全性是错误的。

当我尝试在 ConsoleApplicationProject 中调用此服务时，我得到了这个异常:

System.ServiceModel.Security.MessageSecurityException exception was not handled HResult = 2146233087 Message = the HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'Basic realm = "Foooo" '. [...]

有人可以在 WP8 中使用 Credentials 发布带有 Web 服务调用的示例吗？

Answer 1

如果可以使用<security mode="TransportCredentialOnly" />那么你的问题就解决了

请注意您提供的配置中缺少端点地址，我假设您已经这样做了，所以不要透露您的 url。

客户端 web.config 的变化

<bindings>
      <basicHttpBinding>
        <binding name="ersteinb">
          <security mode="TransportCredentialOnly"/> //note this change
        </binding>
      </basicHttpBinding>
    </bindings>

更改调用服务的代码:

    PDAErsteinMobileServiceClient client = new PDAErsteinMobileServiceClient();
    using (OperationContextScope scope = new OperationContextScope(client.InnerChannel)) {
                HttpRequestMessageProperty request = new HttpRequestMessageProperty();
                request.Headers[System.Net.HttpRequestHeader.Authorization] = "Basic " + EncodeCredentials("foo", "foofoo");
                OperationContext.Current.OutgoingMessageProperties.Add(HttpRequestMessageProperty.Name, request);
                client.GetAttelageCollectionAsync();
                }

//use this function 
private string EncodeCredentials(string username, string password) {
    string credentials = username + ":" + password;
    var asciiCredentials = (from c in credentials
                            select c <= 0x7f ? (byte)c : (byte)'?').ToArray();

    return Convert.ToBase64String(asciiCredentials);
}

服务 web.config 的变化

<system.serviceModel>
    <services>
      <service behaviorConfiguration="ValidatorServiceBehaviour"
               name="WCFServiceLibrary.SettingsService">
        <endpoint binding="basicHttpBinding"

                  contract="PDAErsteinService.IPDAErsteinMobileService"  />
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:8080/PDAErsteinService/" />
          </baseAddresses>

      </service>
    </services>

          <serviceCredentials>
            <userNameAuthentication userNamePasswordValidationMode="Custom"
                                    customUserNamePasswordValidatorType="UserValidator.Validator, UserValidator" />
          </serviceCredentials>
        </behavior>
      </serviceBehaviors>
    </behaviors>

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

      </basicHttpBinding>
    </bindings>
