WCF客户端配置 - app.config文件

客户端调用WCF接口

C# Code:

/// <summary>
/// 职员资料的WCF接口
/// </summary>
public class WCF_Employee : WCF_Base<IHR>, IBridge_Employee
{
/// <summary>
/// 获取员工资料
/// </summary>
/// <param name="employeeName"></param>
/// <returns></returns>
public DataTable GetEmplyoeeTable(string employeeName)
{
return this.Excute(client =>
{
byte[] loginTicket = WebServiceSecurity.EncryptLoginer(Loginer.CurrentUser);
byte[] bs = client.GetEmplyoeeTable(loginTicket, employeeName);
return ZipTools.DecompressionDataSet(bs).Tables[0];
});
}
}

客户端WCF_Base基类

C# Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.ServiceModel;
using System.Text;
using System.Threading.Tasks;

namespace CSFrameworkV5.WebRef
{

/// <summary>
/// WCF客户端代理层-基类
/// </summary>
/// <typeparam name="T"></typeparam>
public class WCF_Base<T> where T : class
{
/// <summary>
/// 执行WCF方法
/// </summary>
/// <param name="action">调用WCF接口核心逻辑</param>
protected void Excute(Action<T> action)
{
T svc = null;

try
{
svc = WCFFactory.Create<T>();
action(svc);
this.CloseService(svc as ICommunicationObject);//关闭WCF服务
}
catch (Exception ex)
{
if (svc != null) this.CloseService(svc as ICommunicationObject);
throw ex;
}
}

/// <summary>
/// 执行WCF方法
/// </summary>
/// <typeparam name="R">数据类型</typeparam>
/// <param name="action">调用WCF接口核心逻辑</param>
/// <returns></returns>
protected R Excute<R>(Func<T, R> action)
{
T svc = null;

try
{
svc = WCFFactory.Create<T>();//创建WCF接口实例
R result = action(svc);//调用接口逻辑
this.CloseService(svc as ICommunicationObject);//关闭WCF服务
return result;
}
catch (Exception ex)
{
if (svc != null) this.CloseService(svc as ICommunicationObject);
throw ex;
}
}

/// <summary>
/// 执行指定WCF接口的方法
/// </summary>
/// <typeparam name="M">WCF接口</typeparam>

protected R Excute<R, M>(Func<M, R> action) where M : class
{
M svc = null;

try
{
svc = WCFFactory.Create<M>();//创建WCF接口实例
R result = action(svc);//调用接口逻辑
this.CloseService(svc as ICommunicationObject);//关闭WCF服务
return result;
}
catch (Exception ex)
{
if (svc != null) this.CloseService(svc as ICommunicationObject);

throw ex;
}
}

private void CloseService(ICommunicationObject svc)
{
try
{
//查看连接状态，关闭WCF
CommunicationState state = svc.State;//创建WCF通道，默认State=Opened;

svc.Close();

//svc.Close();//测试关闭状态下，调用Close
}
catch
{

}
}

WCFFactory

C# Code:

/// <summary>
/// 动态创建WCF接口透明代理
/// </summary>
/// <typeparam name="T">WCF接口，如：ICommonService</typeparam>
/// <param name="uri">连接地址</param>
/// <returns></returns>
public static T Create<T>(string uri = "") where T : class
{
//获取WCF接口的名称，如：ICommonService
string iName = typeof(T).Name;

//获取接口的URI地址，必须是主程序的App.config配置文件
if (String.IsNullOrWhiteSpace(uri))
uri = System.Configuration.ConfigurationManager.AppSettings[iName];

//支持4种凭据类型：None/ Basic / Windows / Certificate
string UseCredentials = System.Configuration.ConfigurationManager.AppSettings["UseCredentials"];

//default:None
switch (UseCredentials)
{
case "Basic": return CreateBasic<T>(uri);//Basic认证，需要指定Windows用户/密码
case "Windows": return CreateWindows<T>(uri);//Windows认证，需要指定Windows用户/密码
case "Certificate": return CreateCertificate<T>(uri);//Certificate认证，需要提供SSL证书文件
default: return CreateNone<T>(uri);
}

//是否使用https协议,默认false
//bool https = System.Configuration.ConfigurationManager.AppSettings["UseHttps"].ToLower() == "true";

//C#动态创建WCF协议配置实例(不依赖App.config配置文件)
//var myBinding = CreateWSHttpBinding(https);

//获取协议配置并创建实例，必须是主程序的App.config配置文件
//var myBinding = new WSHttpBinding("WSHttpBinding");
//var myBinding = new BasicHttpBinding("BasicHttpBinding");
//var myBinding = new NetTcpBinding("NetTcpBinding");
}
