问题
I can't invoke a basic wcf web method in the browser even with <ServiceMetadata httpGetEnabled="True"/> in the config file.
For the source, code, it's very basic:
For the interface:
[ServiceContract]
public interface IService1
{
[OperationContract]
[WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare)]
string GetData();
[OperationContract]
CompositeType GetDataUsingDataContract(CompositeType composite);
// TODO: ajoutez vos opérations de service ici
}
And for the implementation:
public string GetData()
{
return ("{'code':'yes'}");
}
This method works fine in the built-in visual studio wcf service tester and returns {'code':'yes'}.
In the browser, when I call the http://localhost:54421/Service1.svc/GetData, it displays a blank page. How can I resolve this?
回答1:
I am doing that by creating additional endpoint behavior for REST calls so I can have different clients. Take a look at this configuration:
<endpointBehaviors>
<behavior name="RESTFriendly">
<webHttp />
</behavior>
</endpointBehaviors>
in your service definition add endpoint which is using this behavior
<endpoint address="/easy" behaviorConfiguration="RESTFriendly" ...
now you can call your service both from browser and from wcf client. To call it from browser:
http://localhost:54421/Service1.svc/easy/GetData
ServiceMetadata is for different purpose here is link to documentation. Basically it means your service will expose information about itself so external developers can create proxy clients.
回答2:
Most browsers will not display json results in browser. Generally, you will see a blank page (try viewing the source) or you will get prompted for a download.
If you are using Firefox there are some add-ons to view JSON and the Poster add-on for testing web services.
If you are using Google Chrome you can try Pretty JSON
