svc文件和宁静的Web服务

Question

I have a restful service living on our company server IIS 7.5. The url is http://11.52.36.251/MessagingServices/IData.svc . I used Restsharp/Restclient to test it from client side.

When I put the url in the browser and hit "ENTER", the wsdl link was generated.

But I heard that restful service didn't have a wsdl, but why I saw it?

I checked the code inside the service, there are

public interface IData
{
    [OperationContract]
    [WebGet(BodyStyle=WebMessageBodyStyle.Bare,
        ResponseFormat=WebMessageFormat.Json,
        UriTemplate="/api")]
    void GetApi();

    [OperationContract]
    [WebGet(BodyStyle = WebMessageBodyStyle.Bare, 
        RequestFormat = WebMessageFormat.Json, 
        ResponseFormat = WebMessageFormat.Json, 
        UriTemplate = "/GetIData?iId={iId}&facilityId={internalId}")]
    IDTO GetIData(string iId, string internalId);
}

Is it a fake restful service or other reason?

Answer 1

A restful service should be able to document itself strictly through its API, or simple readable HTML document. However, any service developed in WCF will have a WSDL by default, so just because a service has a WSDL doesn't mean its not RESTful. If it truly is RESTful, the service developer should disable the mex endpoint to keep its WSDL from being published, thus assuring clients are using the service in the intended way.
