Je dois utiliser plusieurs hôtes sous IIS pour WCF. Nous utilisons wshttpbinding et nous n’avons trouvé AUCUN succès jusqu’à présent, même après avoir vérifié quelques questions similaires sur stackoveflow.
Voici mon web.config
<?xml version="1.0"?>

Qu'est-ce qui pourrait éventuellement être faux?
apprécierait toute aide.
Merci.
La solution
Essayez ceci et voyez si cela fonctionne (je ne suis vraiment pas sûr que cela fonctionnera pour les deux adresses, mais cela pourrait être le cas):
protected override System.ServiceModel.ServiceHost CreateServiceHost(Type serviceType, Uri[] baseAddresses)
{
if (HttpContext.Current != null)
{
string baseAddress = string.Format("http://{0}{1}{2}", HttpContext.Current.Request.Url.Host, HttpContext.Current.Request.Url.Port == 80 ? "" : ":" + HttpContext.Current.Request.Url.Port, HttpContext.Current.Request.CurrentExecutionFilePath);
Uri baseURI = new Uri(baseAddress);
return base.CreateServiceHost(serviceType, new Uri[] { baseURI });
}
//We did the best we could, but there is no current HTTP request.
//Just fall back to the base service host factory
return base.CreateServiceHost(serviceType, baseAddresses);
}
Il ne semble pas que la sécurité du transport soit activée, donc supposons " http: // " est probablement sans danger, mais si vous devez l'activer, vous devrez modifier le code pour obtenir le http s : //.
Autres conseils
Hé, ajoutez ceci dans votre <system.serviceModel> section config
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" />
et
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class yourService : IyourService
{ ..... }
ajouter using System.ServiceModel.Activation; à votre code
J'avais aussi le même problème.
