Brauchen Sie Hilfe mit AJAX-Enabled WCF-Dienste (Bitte schauen @ System.ServiceModel in Web.Config)

Question

Ich habe einige Probleme mit diesem seit ein paar Tagen jetzt ... Ich habe eine WCF-Klassenbibliothek erstellt - WebAPILibrary. Es ist unter meiner Lösung, die auch mein Webprojekt enthält.

Ich versuche jetzt, eine AJAX/JSON-Antwort auf eine Suchanfrage zu aktivieren.

In den Client-Code-Beispiele, ich sehe etwas in der Art:

function btnsrch_onclick() { 

       var query = document.getElementById('q'); 
       var type = document.getElementById('type'); 

       $(document).ready(function(){ 
        $.getJSON("http://api.domain.com/services/trade.svc?q=" + query.value + "&type=" + type.value + "&format=json", 
         function(data){ 
          $.each(data.items, function(i,item){ 
          $("<img/>").attr("src", item.media.m).appendTo("#images"); 
           if (i == 3) return false; 
         }); 
        }); 
       }); 

       } 

Mein Problem ist, die bis zu diesem Punkt, ich habe meine WCF-Klassenbibliothek in meinem Webprojekt glücklich worden verweist. Aber jetzt scheint es, ich muss eine SVC-Datei erstellen und verwenden, um meine Javascript AJAX/JSON-Aufrufe auszuführen.

meine Frage:

1) Wie kann ich die SVC-Datei in Zusammenarbeit mit meiner WCF-Klassenbibliothek erstellen? 2) Ich bin mir nicht sicher, was ich unter System.ServiceModel für die Web.config meines Webprojekts setzen muss. Könnte eine freundliche Seele sich ansehen, was ich gerade habe und mir unter mitteilen, was ich tun muss?

Answer 1

Sie sollten nie verweisen Ihre WCF-Bibliothek in einem anderen Projekt. Es ist als Service gedacht, nicht als Klassenbibliothek.
