Trying to get basic Http URL with querystring parameters processed in WCF service
I'm trying to process a post by a third party server (Paypal) processed by my server through a WCF (.Net 3.5 SP1) service. All I need is to get and process the values with the query string. This sounds incredibly easy, but after a weekend, I'm still stumped. Any help would be greatly appreciated.
Passing the following URL from my browser to the service causes a AddressFilter mismatch fault (below).
http://localhost:9409/PPInfo.svc/ReadResponse?RESULT=0&AUTHCODE=10001&RESPMSG=APROVED&PNREF=12345
produces
<Fault xmlns="http://schemas.microsoft.com/ws/2005/05/envelope/none">
- <Code>
<Value>Sender</Value>
- <Subcode>
<Value xmlns:a="http://schemas.microsoft.com/ws/2005/05/addressing/none">a:DestinationUnreachable</Value>
</Subcode>
</Code>
- <Reason>
<Text xml:lang="en-US">The message with To 'http://localhost:9409/PPInfo.svc/ReadResponse?RESULT=0&AUTHCODE=10001&RESPMSG=APROVED&PNREF=12345' cannot be processed at the receiver, due to an AddressFilter mismatch at the EndpointDispatcher. Check that the sender and receiver's EndpointAddresses agree.</Text>

var qString = HttpContext.Current.Request.QueryString;

log.LoginPageMsg = s;

Besides the typo in your code, I believe you have two problems that are easily correctable:
1) For a RESTful service, you should define an endpoint behavior and enable the webHttp behavior. You can do this by adding an <endpointBehavior>
to your web.config as such:
<behaviors>
<serviceBehaviors>
<behavior name="ASEEESPrivate.PPInfoBehavior">
<serviceMetadata httpGetEnabled="true" />
<serviceDebug includeExceptionDetailInFaults="true" />
</behavior>
</serviceBehaviors>
<endpointBehaviors>
<behavior name="ASEEESPrivate.PPInfoEndpointBehavior">
<webHttp />
</behavior>
</endpointBehaviors>
</behaviors>
And then add this endpoint behavior to your service definition:
<service behaviorConfiguration="ASEEESPrivate.PPInfoBehavior" name="WcfRestService1.PPInfo">
<endpoint address="" binding="webHttpBinding" contract="WcfRestService1.IPPInfo"
behaviorConfiguration="ASEEESPrivate.PPInfoEndpointBehavior">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>
2) Secondly, you define a UriTemplate
for your service with placeholders (result, authcode, etc.) but you don't define parameters for them in your interface. If you're going to define a UriTemplate
for your service definition with placeholders, then you need to have your service define those parameters accordingly. You can do that as such:
[ServiceContract]
public interface IPPInfo
{
// expecting RESULT = 0 and RESPMSG = APPROVED
[OperationContract]
[WebGet(UriTemplate = "ReadResponse?RESULT={result}&AUTHCODE={authcode}&RESPMSG={respmsg}&AVSDATA={avsdata}&PNREF={pnref}",
BodyStyle = WebMessageBodyStyle.Bare, RequestFormat = WebMessageFormat.Xml)]
void ReadResponse(string result, string authcode, string respmsg, string avsdata, string pnref);
}
[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall, AddressFilterMode = AddressFilterMode.Any)]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class PPInfo : IPPInfo
{
public void ReadResponse(string result, string authcode, string respmsg, string avsdata, string pnref)
{
...
}
}
By using a UriTemplate
, you don't need to extract your querystring parameters out; or, if you want to extract parameters from your querystring, don't define a UriTemplate
.
Once I made these two changes, I was able to get the service to run locally on my machine.
I hope this helps!
