我有一个WCF SOAP Web服务,我将在Windows Phone 8应用程序中使用。
这是我服务上的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>
当我打电话给我的服务时,我需要发送凭证,因为他是在反向代理下。
我找不到另外一种方法来通过凭证来调用我的服务:
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,我得到了一个例外:
System.ServiceModel.ProtocolException异常未由用户处理HResult代码= 2146233087消息=远程服务器返回了 意外响应:(401)需要授权。在Silverlight中,a 即使服务发送a,也可以报告404响应代码 不同的错误代码。 Source = System.ServiceModel StackTrace:[...]
我确信我的凭据很好,但我很确定我不会用好的方式发送它们。如果不是这样,那么web.config中的安全性可能是假的。
当我尝试在ConsoleApplicationProject中调用此服务时,我遇到了这个异常:
System.ServiceModel.Security.MessageSecurityException异常是 未处理HResult = 2146233087 Message = HTTP请求 未经授权的客户端身份验证方案'匿名'。该 从服务器收到的身份验证标头是'Basic realm = “Foooo”'。 [...]
有人可以在带有凭据的WP8中使用webservice调用发布样本吗?
答案 0 :(得分:0)
如果您可以使用<security mode="TransportCredentialOnly" />
,则问题将得到解决
只是要注意您提供的配置中缺少端点地址,我认为您这样做是为了不泄露您的网址。
客户端web.config中的更改
<bindings>
<basicHttpBinding>
<binding name="ersteinb">
<security mode="TransportCredentialOnly"/> //note this change
</binding>
</basicHttpBinding>
</bindings>
调用服务的代码更改:
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);
}
