这里没有理论上的东西，仅仅是做下记录。我这个例子偷懒下了，直接在VS2008里面建了个WCF服务应用程序
一、接口,用WebGet的时候需要添加命名空间：System.ServiceModel;System.ServiceModel.Web;
[ServiceContract]
public interface IEmployeeService
{
[WebGet(UriTemplate = "employees", ResponseFormat = WebMessageFormat.Json)]
[OperationContract]
List<Employee> GetAll();[WebGet(UriTemplate = "employees/{id}", ResponseFormat = WebMessageFormat.Json)]
[OperationContract]
Employee GetById(string id);[WebInvoke(Method = "POST", UriTemplate = "add", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
[OperationContract]
void Add(Employee employee);[WebInvoke(Method = "PUT", UriTemplate = "edit", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]
[OperationContract]
void Edit(Employee employee);[WebInvoke(Method = "DELETE", UriTemplate = "delete/{id}")]
[OperationContract]
void Delete(string id);
}
二、实体类
[DataContract]
public class Employee
{
[DataMember]
public int Id { get; set; }
[DataMember]
public string Name { get; set; }
[DataMember]
public string Description { get; set; }
}
三、接口实现类
[ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)]
public class EmployeeService : IEmployeeService
{
public List<Employee> Employees { get; set; }
public EmployeeService()
{
Employees = new List<Employee>
{
new Employee{ Id=1, Name="jack",Description="this is jack"},
new Employee{ Id=2, Name="tom",Description="this is tom"},
new Employee{ Id=3, Name="paul",Description="this is paul"}
};
}
#region IEmployeeService Memberspublic List<Employee> GetAll()
{
return Employees;
}public Employee GetById(string id)
{
return Employees.FirstOrDefault(e => e.Id == int.Parse(id));
}public void Add(Employee employee)
{
Employees.Add(employee);
}public void Edit(Employee employee)
{
var entity = Employees.FirstOrDefault(e => e.Id == employee.Id);
entity.Name = employee.Name;
entity.Description = employee.Description;
}public void Delete(string id)
{
Employees.RemoveAll(e => e.Id == int.Parse(id));
}#endregion
}
四、配置文件，
binding="webHttpBinding" 绑定方式一定要用webHttpBinding
<system.serviceModel>
<services>
<service behaviorConfiguration="WCFRestfulSample.EmployeeServiceBehavior" name="WCFRestfulSample.EmployeeService">
<endpoint address="" binding="webHttpBinding" contract="WCFRestfulSample.IEmployeeService" behaviorConfiguration="WCFRestfulSample.RestfulBehavior">
<identity>
<dns value="localhost" />
</identity>
</endpoint>
<endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange" />
</service>
</services>
<behaviors>
<endpointBehaviors>
<behavior name="WCFRestfulSample.RestfulBehavior">
<webHttp/>
</behavior>
</endpointBehaviors>
<serviceBehaviors>
<behavior name="WCFRestfulSample.EmployeeServiceBehavior">
<!-- To avoid disclosing metadata information, set the value below to false and remove the metadata endpoint above before deployment -->
<serviceMetadata httpGetEnabled="true"/>
<!-- To receive exception details in faults for debugging purposes, set the value below to true. Set to false before deployment to avoid disclosing exception information -->
<serviceDebug includeExceptionDetailInFaults="true"/>
</behavior>
</serviceBehaviors>
</behaviors>
<!--<bindings>
<webHttpBinding>
<binding name="defaultRest" >
<readerQuotas maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxDepth="64" maxNameTableCharCount="2147483647" />
<security mode="None" />
</binding>
</webHttpBinding>
</bindings>-->
</system.serviceModel>
五、调用过程
const string sUserAgent = "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 5.2; .NET CLR 1.1.4322; .NET CLR 2.0.50727)";
const string sContentType = "application/json";
static void Main(string[] args)
{
Add();
Console.ReadKey();
}
static void Select()
{
HttpWebRequest request = WebRequest.Create("http://localhost:32582/EmployeeService.svc/employees") as HttpWebRequest;
request.Method = "GET";
request.ContentType = "text/html;charset=UTF-8";
string result = string.Empty;
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
using (var reader = new StreamReader(response.GetResponseStream(), Encoding.Default))
{
result = reader.ReadToEnd();
}
}
Console.WriteLine(result);
}static void Add()
{
string url = "http://localhost:32582/EmployeeService.svc/add";
HttpWebRequest httpRequest = WebRequest.Create(url) as HttpWebRequest;
httpRequest.UserAgent = sUserAgent;
httpRequest.ContentType = sContentType;
httpRequest.Method = "POST";
//一定要先序列化然后在写入流
byte[] data = GetPostData();httpRequest.ContentLength = data.Length;
using (Stream requestStream = httpRequest.GetRequestStream())
requestStream.Write(data, 0, data.Length);
using (var responseStream = httpRequest.GetResponse().GetResponseStream())
{
using (StreamReader responseReader = new StreamReader(responseStream, Encoding.UTF8))
{
var result = responseReader.ReadToEnd();
Console.WriteLine("post return result:{0}", result);
}
}
}static byte[] GetPostData()
{
var employee = new Employee()
{
Id = 98,
Name = "123sdf3",
Description = "this is my test..."
};
var json = ToJson(employee);
Console.WriteLine(json);
return Encoding.UTF8.GetBytes(json);
}
static string ToJson(object item)
{
DataContractJsonSerializer serializer = new DataContractJsonSerializer(item.GetType());using (MemoryStream ms = new MemoryStream())
{
serializer.WriteObject(ms, item);StringBuilder sb = new StringBuilder();
sb.Append(Encoding.UTF8.GetString(ms.ToArray()));
return sb.ToString();
}
}
[DataContract]
public class Employee
{
[DataMember]
public int Id { get; set; }
[DataMember]
public string Name { get; set; }
[DataMember]
public string Description { get; set; }
}
