利用WCF创建简单的RESTFul Service

利用WCF创建简单的RESTFul Service 1、 用VS2013创建一个WCF的工程，如下图所示：

2、 对IService1.cs文件进行修改，在里面添加服务契约和数据契约，具体代码如下所示：

using System;

using System.Collections.Generic;

using System.Linq;

using System.Runtime.Serialization;

using System.ServiceModel;

using System.ServiceModel.Web;

using System.Text;

namespace WCFcompany

{

// 注意: 使用“重构

”菜单上的“重命名”命令，可以同时更改代码和配置文件中的接口名“IService1”。

[ServiceContract]

public interface IService1

{

// TODO: 在此添加您的服务操作

[OperationContract]

[WebGet(UriTemplate = "getcustomer/{id}", RequestFormat =

WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]

Customer GetCustomerById(string id);

[OperationContract]

[WebGet(UriTemplate = "getallcustomer", RequestFormat =

WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]

List<Customer> GetAllCustomer();

[OperationContract]

[WebInvoke(Method = "POST", UriTemplate = "addcustomer", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)]

bool AddCustomer(Customer cust);

[OperationContract]

[WebInvoke(Method = "PUT", UriTemplate = "updatecustomer", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Wrapped)]

bool UpdateCustomer(string id,string name);

[OperationContract]

[WebInvoke(Method = "DELETE", UriTemplate = "deletecustomer",

RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json)] bool DeleteCustomer(string id);

}

// 使用下面示例中说明的数据约定将复合类型添加到服务操作。

[DataContract]

public class Customer

{

string cust_id ; string cust_name;

string addr;

string tel_no;

string zip;

[DataMember]

public string Cust_id

{

get { return cust_id; }

set { cust_id = value; }

}

[DataMember]

public string Cust_name

{

get { return cust_name; }

set { cust_name = value; }

}

[DataMember]

public string Addr

{

get { return addr; }

set { addr = value; }

}

[DataMember]

public string Tel_no

{

get { return tel_no; }

set { tel_no = value; }

}

[DataMember]

public string Zip

{

get { return zip; }

set { zip = value; }

}

}

}

3、 在Service1.svc.cs文件中实现IService1接口，代码如下： using System;

using System.Collections.Generic;

using System.Linq;

using System.Runtime.Serialization;

using System.ServiceModel;

using System.ServiceModel.Activation;

using System.ServiceModel.Web;

using System.Text;

using System.Data;

using System.Data.SqlClient;

using SqlServerDAL;

namespace WCFcompany

{

// 注意: 使用“重构”菜单上的“重命名”命令，可以同时更改代码、svc 和配置文件中的类名“Service1”。

// 注意: 为了启动 WCF 测试客户端以测试此服务，请在解决方案资源管理器中选择 Service1.svc 或 Service1.svc.cs，然后开始调试。

//以下两个特性是一定要加上去的，否则报错

[AspNetCompatibilityRequirements(RequirementsMode =

AspNetCompatibilityRequirementsMode.Allowed)]

[ServiceBehavior(InstanceContextMode = InstanceContextMode.PerCall)] public class Service1 : IService1

{

private DataTable SqlConnHelpGetDataMethod(string sql)

{

CnnHelper.ConnectionSql();

CnnHelper.IsOpenHelp();

http://wendang.chazidian.comeCommand(sql, CommandType.Text);

DataTable dt = http://wendang.chazidian.comeSqlDataReader(); return dt;

}

private int SqlConnHelpSetDataMethod(string sql)

{

CnnHelper.ConnectionSql();

CnnHelper.IsOpenHelp();

http://wendang.chazidian.comeCommand(sql, CommandType.Text);

return http://wendang.chazidian.comeExecuteNonQuery();

}

public Customer GetCustomerById(string id)

{

//string sql = "select * from customer where cust_id='" + id + "'"; //Customer cust = new Customer();

//DataTable dt = SqlConnHelpGetDataMethod(sql);

//if (dt != null && dt.Rows.Count == 1)

//{

// cust.Cust_id = dt.Rows[0][0].ToString();

// cust.Cust_name = dt.Rows[0][1].ToString();

// cust.Addr = dt.Rows[0][2].ToString();

// cust.Tel_no = dt.Rows[0][3].ToString();

// cust.Zip = dt.Rows[0][4].ToString();

//}

//else cust = null;

//return cust;

Customer cust = new Customer();

cust.Cust_id = "C0001";

cust.Cust_name = "Jack";

cust.Addr = "asd";

cust.Tel_no = "253y565u5";

cust.Zip = "210940923";

return cust;

}

public List<Customer> GetAllCustomer()

{

//List<Customer> custList = new List<Customer>();

//string sql = "select * from customer";

//DataTable dt = SqlConnHelpGetDataMethod(sql);

//if (dt != null && dt.Rows.Count != 0)

//{

// for (int i = 0; i < dt.Rows.Count; i++)

// {

// Customer cust = new Customer();

// cust.Cust_id = dt.Rows[i][0].ToString();

// cust.Cust_name = dt.Rows[i][1].ToString();

// cust.Addr = dt.Rows[i][2].ToString();

// cust.Tel_no = dt.Rows[i][3].ToString();

// cust.Zip = dt.Rows[i][4].ToString();

// custList.Add(cust);

// }

//}

//else custList = null;

//return custList;

List<Customer> custList = new List<Customer>();

Customer cust0 = new Customer() { Cust_id="C0001", Cust_name="Tom", Addr="asfasdg", Tel_no="13345569", Zip="1233234" };

Customer cust1 = new Customer() { Cust_id = "C0002", Cust_name = "Jack", Addr = "sdgsdgg", Tel_no = "15634579", Zip = "56456776" };

custList.Add(cust0);

custList.Add(cust1);

return custList;

}

public bool AddCustomer(Customer cust)

{

string sql = "insert into customer values('" + cust.Cust_id + "','" + cust.Cust_name + "','" + cust.Addr + "','" + cust.Tel_no + "','" + cust.Zip + "')";
