A simple WCF RESTful service

WCF a lot of rest instances online, here is my days to learn and practice through, is a note it.

1. Service Contract

[ServiceContract]public　interface　 IRESTService{}

In the specific operation definition, there are several parameters to note:

1, WebGet and webinvoke the difference seems to be the definition of method is different, webget use "get", WebInvoke is more flexible.

2, UriTemplate with {value} corresponding parameter list.

3, Webmessageformat includes XML and JSON, there is an online article to achieve raw, has not been carefully studied.

In the case of a simple example, you can customize a return object

1　[OperationContract]
2　[WebGet(UriTemplate　=　"{name}?token={token}",　 ResponseFormat　=　WebMessageFormat.Json)]
3　Person　GetPerson(string　name,　string　token);

And a return picture of the

1　[OperationContract]
2　[WebGet(UriTemplate　=　"Data/{id}?token={token}")]
3　Stream　GetData(string　id,　string　token);

Note the variable type in the definition is string, and the other token is to make a simple authentication in the future, not to think clearly, not in the context of this discussion.

2. Host

It's best to use webservicehost directly,

WebServiceHost　restHost　=　new　WebServiceHost(typeof (RESTService),new　Uri ("http://localhost/RestService"));

Trouble with ServiceHost, but more flexible.

1　ServiceHost　GetRestHost(Uri　 baseAddress)
2　{
3　　　　　　　　 ServiceHost　host　=　new　ServiceHost(typeof (RESTService),　baseAddress);
4　　　　　　　　 WebHttpBinding　binding　=　new　WebHttpBinding();
5　　　　　　　　　ServiceEndpoint　endpoint　=　 host.AddServiceEndpoint(typeof(IRESTService),　binding,　 baseAddress);
6　　　　　　　　　WebHttpBehavior　httpBehavior　=　new　 WebHttpBehavior();
7　　　　　　　　　endpoint.Behaviors.Add(httpBehavior);
8　　　　　　　　　return　host;
9　}

3. Concrete Operation Example

3.0 first define a simple data contract

1　[DataContract]
2　public　class　Person
3　{
4　　　　　[DataMember]public　string　Name{get;set;}
5　　　　　[DataMember]public　DateTime　Birthday{get;set;}
6　}

Left a datetime type of data, ready to study the client when used, not all say JS under processing JSON date and WCF is not the same.
