. NET RESTful Web Services,. netrestful

I have seen RESTful Web Services a long time ago. I didn't care about it, nor did I find any relevant materials to learn. Today, I have an occasional opportunity to find some research materials and find that RESTful is "simple but not simple ". The following is an example:

1. Project Structure

2 REST Service Interface Definition

1 using System; 2 using System. collections. generic; 3 using System. linq; 4 using System. text; 5 using System. serviceModel; 6 using System. serviceModel. web; 7 namespace Jack_Restful_Service 8 {9 10 [ServiceContract (Name = "RestfulService", Namespace =" http://www.cnblogs.com/isaboy ")] 11 public interface IRestDemoServices12 {13 [OperationContract] 14 [WebGet (UriTemplate = Routing. getClientRoute, BodyStyle = WebMessageBodyStyle. bare)] 15 string GetClientNameById (string Id); 16 17 [OperationContract] 18 [WebGet (UriTemplate = Routing. addClientRoute, BodyStyle = WebMessageBodyStyle. bare)] 19 string Add (string a, string B); 20 // error21 // string Add (int a, int B ); 22 23 [OperationContract] 24 [WebGet (UriTemplate = Routing. loginClientRoute, BodyStyle = WebMessageBodyStyle. bare)] 25 string Login (string uname, string upwd); 26 27 // post 28 [OperationContract] 29 [WebInvoke (RequestFormat = WebMessageFormat. json, 30 ResponseFormat = WebMessageFormat. json, 31 BodyStyle = WebMessageBodyStyle. bare, 32 Method = "POST", UriTemplate = "/Client/UpdateUser/{uname}")] 33 User UpdateUser (string uname, User newUser ); 34 35} 36 // URI Route 37 public static class Routing38 {39 public const string GetClientRoute = "/Client/{id }"; 40 41 public const string AddClientRoute = "/Client/{a}, {B}"; 42 // {uname} the parameter name and string Login (string uname, string upwd); 43 public const string LoginClientRoute = "/Client/{uname }__ {upwd}"; 44} 45 46 47}

 

3 REST service interface implementation

 1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Text; 5 using System.ServiceModel; 6 using System.ServiceModel.Activation; 7 namespace Jack_Restful_Service 8 { 9 10     [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single,11         ConcurrencyMode = ConcurrencyMode.Single,12         IncludeExceptionDetailInFaults = true,13         Namespace = "http://www.cnblogs.com/isaboy")]14     [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]15     public class RestDemoServices : IRestDemoServices16     {17         //GET18         public string GetClientNameById(string Id)19         {20             string ReturnString = "Your id is: " + Id;21 22             return ReturnString;23         }24 25         public string Add(string a, string b)26         {27             int sum = int.Parse(a) + int.Parse(b);28             return sum.ToString();29         }30 31         public string Login(string uname, string upwd)32         {33             if (uname == "admin" && upwd == "admin")34             {35                 return "success";36             }37             else38             {39                 return "false";40             }41         }42         //POST43         public User UpdateUser(string uname, User newUser)44         {45             return newUser;46         }47     }48 49 }

 

4. HOST

1  Console.WriteLine("----------Restful Service Start--------------");2  RestDemoServices demoServices = new RestDemoServices();3  WebServiceHost _serviceHost = new WebServiceHost(demoServices, new Uri("http://localhost:8000/RestfulService"));4   _serviceHost.Open();5   Console.WriteLine("----------Restful Service Opened--------------");6   Console.WriteLine("http://localhost:8000/RestfulService/Client/8");7   Console.WriteLine("http://localhost:8000/RestfulService/Client/2,5");8   Console.WriteLine("http://localhost:8000/RestfulService/Client/admin__admin");

In addition, we can use the code for testing.

 1 using System; 2 using System.Collections.Generic; 3 using System.Linq; 4 using System.Text; 5 using System.Web; 6 using System.Net; 7 using System.IO; 8 namespace PostServiceTest 9 {10     class Program11     {12         static void Main(string[] args)13         {14             //get15             HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://localhost:8000/RestfulService/Client/8");16             WebResponse response = request.GetResponse();17             string result = new StreamReader(response.GetResponseStream()).ReadToEnd();18             Console.WriteLine(result);19 20             //post21             string requestData = "{\"uname\":\"admin\",\"upwd\":\"admin\"}";22             byte[] data = Encoding.UTF8.GetBytes(requestData);23             request = (HttpWebRequest)WebRequest.Create("http://localhost:8000/RestfulService/Client/UpdateUser/admin");24             request.Method = "POST";25             request.ContentType = "application/json";26             Stream dataStream = request.GetRequestStream();27             dataStream.Write(data, 0, data.Length);28             dataStream.Close();29 30             response = request.GetResponse();31             result = new StreamReader(response.GetResponseStream()).ReadToEnd();32             Console.WriteLine(result);33             Console.ReadKey();34         }35     }36 }
