Calling a RESTful WCF Service

Hi,

How about this?

[OperationContract]
    [WebInvoke
        (Method = "POST",
        RequestFormat = WebMessageFormat.Xml,
        UriTemplate = "/SetGasPrice/For/ZipCode/{zipCode}/Price/{price}"
        )]
    void SetPriceDataForZipCode(string zipCode, string price);
}

Got this from here:

Cheers,

Darren

Hi Darren,

I managed to fix the issue by doing the following:

1. Removed old code and started from scratch.
2. Created WCF Library and added a new service and the same method.
The method signature is:

[WebInvoke(Method = "POST", UriTemplate = "submitPayment", BodyStyle = WebMessageBodyStyle.Wrapped, RequestFormat = WebMessageFormat.Xml, ResponseFormat = WebMessageFormat.Xml)]
        [OperationContract]
        Stream submitPaymentToBank(Stream info);

3. Made sure I exposed an endpoint with WebHttpBinding binding. Also I added an endpoint behavior that used webHttp behavior.

Config file is:

<system.serviceModel>
    <services>
      <service behaviorConfiguration="CreditCardWebServiceREST.CreditCardWebServiceRESTBehavior"
        name="CreditCardWebServiceREST.CreditCardWebServiceREST">
        <clear />
        <endpoint behaviorConfiguration="WebBehavior" binding="webHttpBinding"
          bindingConfiguration="" contract="CreditCardWebServiceREST.ICreditCardWebServiceREST"
          listenUriMode="Explicit" />
        <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"
          listenUriMode="Explicit" />
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:2524/CreditCardWebServiceREST/" />
          </baseAddresses>
        </host>
      </service>
    </services>
    <behaviors>
      <endpointBehaviors>
        <behavior name="WebBehavior">
          <webHttp />
        </behavior>
      </endpointBehaviors>
      <serviceBehaviors>
        <behavior name="CreditCardWebServiceREST.CreditCardWebServiceRESTBehavior">
          <serviceMetadata httpGetEnabled="true" />
          <serviceDebug includeExceptionDetailInFaults="false" />
        </behavior>
      </serviceBehaviors>
    </behaviors>
  </system.serviceModel>
 
4. I added a new WCF website that uses the WCF library. This is a pre-compiled site that has a service file with this code.

<%@ ServiceHost Service="CatalogWebServiceREST.CatalogWebServiceREST"
Factory="System.ServiceModel.Activation.WebServiceHostFactory"%>

Also - both projects have a reference to System.ServiceModel.Web.


5. This is my client code.


  string baseAddress = "http://localhost:xxxx/CreditCardService.svc";

            HttpWebRequest req = (HttpWebRequest)HttpWebRequest.Create(baseAddress + "/submitPayment/");
            req.Method = "POST";
            req.ContentType = "text/plain";

            Stream reqStream = req.GetRequestStream();
            string inputData = "MyData";
            System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding();
            byte[] DataToSend = encoding.GetBytes(inputData);
            reqStream.Write(DataToSend, 0, DataToSend.Length);
            reqStream.Close();
            HttpWebResponse resp = (HttpWebResponse)req.GetResponse();
            Console.WriteLine("Client: Receive Response HTTP/{0} {1} {2}", resp.ProtocolVersion, (int)resp.StatusCode, resp.StatusDescription);

            StreamReader loResponseStream = new StreamReader(resp.GetResponseStream(), encoding);
            string lcHtml = loResponseStream.ReadToEnd();
            Console.WriteLine(lcHtml);
            Console.ReadLine();

Everything works like a charm!!!
