service WCF ne pas retourner aucun résultat dans le navigateur

Question

Je crée un service WCF pour mon projet iPhone, mais je contiinue revenir vide et aucun résultat dans le navigateur

J'ai suivi deux guides, mais continuer à l'expérience de la question

Voici ce que j'ai

Service.svc

<%@ ServiceHost Language="C#" Debug="true" Service="Service" CodeBehind="~/App_Code/Service.cs" Factory="System.ServiceModel.Activation.WebServiceHostFactory"%> 

IService.cs

[ServiceContract] 
public interface IService 
{ 

    [OperationContract] 
    string GetData(int value); 

    [OperationContract] 
    CompositeType GetDataUsingDataContract(CompositeType composite); 


    [OperationContract] 
    [System.ServiceModel.Web.WebGet(
     BodyStyle = System.ServiceModel.Web.WebMessageBodyStyle.Bare, 
     RequestFormat = System.ServiceModel.Web.WebMessageFormat.Json, 
     ResponseFormat = System.ServiceModel.Web.WebMessageFormat.Json, 
     UriTemplate = "test/random" 
     )] 
    CompositeType GetTestData(); 
    // TODO: Add your service operations here 
} 

// Use a data contract as illustrated in the sample below to add composite types to service operations. 
[DataContract] 
public class CompositeType 
{ 
    bool boolValue = true; 
    string stringValue = "Hello "; 

    [DataMember] 
    public bool BoolValue 
    { 
     get { return boolValue; } 
     set { boolValue = value; } 
    } 

    [DataMember] 
    public string StringValue 
    { 
     get { return stringValue; } 
     set { stringValue = value; } 
    } 
} 

et Service.cs

public class Service : IService 
{ 
    public string GetData(int value) 
    { 
     return string.Format("You entered: {0}", value); 
    } 

    public CompositeType GetDataUsingDataContract(CompositeType composite) 
    { 
     if (composite.BoolValue) 
     { 
      composite.StringValue += "Suffix"; 
     } 
     return composite; 
    } 
    public CompositeType GetTestData() 
    { 
     return new CompositeType(); 
    } 
} 

Je vais à mon serveur de développement http://localhost:54407/WCFService1/Service.svc/test/random

et vient en blanc

Answer 2

Qu'est-ce que votre look web.config comme ?? Peux-tu le poster aussi?

L'interface de service et l'implémentation du service semblent correctes, ce qui ne pose aucun problème. Votre fichier * .svc semble aussi bien, pour autant que je sache.

Où (dans quel répertoire virtuel) hébergez-vous votre fichier * .svc ?? Êtes-vous sûr que votre URL est correcte? Il devrait être quelque chose comme:

http://yourserver//YourVirtualDir/Service.svc/MethodCall 

Est-ce que c'est ce que vous utilisez? Juste pour tester - pourriez-vous essayer d'utiliser XML comme format de requête et de réponse? Juste pour voir .....

Aussi - Je voudrais essayer sans UriTemplate pour les débutants - encore une fois, juste pour voir.

Answer 3

Assurez-vous que le nom du service est correct dans la configuration Web et * .svc - (correspondent même cas pour webHttpBinding). Cela m'a coûté des heures de cheveux.
