Managed Services Engine

I’ve been playing around with the Managed services engine
In addition to being a design time  governance tool, it also doubles up as a service virtualization engine. I only mention design-time governance because the run-time aspects are not comprehensive out of the box; but with the extensible architecture of WCF its only a matter of adding new policies to the deployed services.

The tool has a nice story around versioning aswell. So far I really like it.

Creating generic contracts for RESTful endpoints Part 3

We saw in the last couple of posts the problems with contract definitions for RESTful applications. Now for the big reveal!

Keep in mind this only applies to the GET based service contracts. The only way I figured was to use a contract thats open ended in terms of query string parameters with a return parameter as specific or open to suite the application need.

For e.g. If we want to have a URL (http://somehost/somepath/?api_key={api_key}&list_id={list_id}&filter={filter}&last_sync={last_sync}) with n query string parameters that returns a chunk of xml one might define the contract like the example below.

[OperationContract]

[WebGet(UriTemplate=”“)]

XElement SomeGETMethod();

This particular example uses LINQ To XML for the xml but it could be the regular xml dom thats manipulation or for that matter a message contract thats a strongly typed CLR object.

Now the way to call this method would be to build up a name value collection as shown

NameValueCollection queryParams = new NameValueCollection();

queryParams.Add(”api_key“, “XYZ“);

queryParams.Add(”auth_token“, “ABC“);

queryParams.Add(”method“, “rtm.tasks.getList“);

//Optional parameters 

if (!string.IsNullOrEmpty(listId))

 queryParams.Add(”list_id“, listId);

if (!string.IsNullOrEmpty(filter))

 queryParams.Add(”filter“,filter);

Use a url template and bind by name

UriTemplate uriTemplate = new UriTemplate("somepath/?api_key={api_key}&list_id={list_id}&filter={filter}&

last_sync={last_sync}");

Uri endpointAddress = uriTemplate.BindByName(new Uri(http://somehost/), queryParams)

And finally create the channel using the endpoint address and fire those requests away!!

public T GetServiceClient(Uri endpointUri)

{

WebChannelFactory<T> channelFactory = new WebChannelFactory<T>();

channelFactory.Endpoint.Binding = new WebHttpBinding();

channelFactory.Endpoint.Address = new EndpointAddress(endpointUri);

channelFactory.Endpoint.Behaviors.Add(new WebHttpBehavior());

return channelFactory.CreateChannel();

}

Where T represents the service contract that we defined with the the generic operation contract
