thrift,不解释了,可支持不同语言的代码之间分布式调用,很好用,很强大,本文使用的版本为0.9.3。Thrift服务器端,使用Android实现。客户端使用C#,VS2015开发。客户端向服务器端发送一个字符串,服务器端(Android的APK)在界面上显示字符串。

1.thrift文件,文件名Hello.thrift
namespace java thrift.test
namespace csharp Thrift.Test
service ThriftTest
{
/** added by wallimn, 2016-01-11*/
void showMessage(1: string msg)
}
2.编译Hello.thrift文件,在命令行中执行如下编译命令,分类生成JAVA及C#的辅助代码
thrift-0.9.3.exe -gen java Hello.thrift
thrift-0.9.3.exe -gen csharp Hello.thrift
3.在Android工程中加入thrift编译生成的文件,加入thrift的jar包,并定义服务接口的实现类
public class ServiceImpl implements ThriftTest.Iface{ @Override public void showMessage(String msg) throws TException { Message msg = new Message(); msg.what = 0x8090; msg.getData().putString("msg",msg); MainActivity.this.handler.sendMessage(msg);//向主线程发消息,显示收到信息 } }
4.Activity布局很简单,只有一个TextView,使用tvMsg保存View对应的变量,显示收到的消息,这里不给出源码了
5.在主界面中(MainActivity)定义消息处理器(handler)成员变量
Handler handler = new Handler(){ public void handleMessage(Message msg){ if(msg.what==0x8090){ String str= (String) msg.getData().get("msg"); tvMsg.setText(str);//Activity上的TextView元素显示消息内容 } } };
6.启动thrift服务端的代码:MainActivity中定义一个线程变量,注意定义成成员变量,Activity创建函数中启动线程
Thread thread = new Thread(){ @Override public void run() { //super.run(); TServerSocket socket = null; try { socket = new TServerSocket(8090); TProcessor processor = new ThriftTest.Processor(new ServiceImpl()); TBinaryProtocol.Factory factory = new TBinaryProtocol.Factory(); TThreadPoolServer.Args tArgs = new TThreadPoolServer.Args(socket); tArgs.processor(processor); tArgs.protocolFactory(factory); TServer server = new TThreadPoolServer(tArgs); //Toast.makeText(MainActivity.this,"服务启动,8090",Toast.LENGTH_LONG).show(); server.serve(); } catch (TTransportException e) { e.printStackTrace(); } } };
7.测试客户端,使用C#编写,注意把thrift编译生成的文件加入工程,引用thrift.dll(自行编译thrift源码获得,源码是个VS的工程,编译很简单)。测试客户端是一个简单的窗体,上面两个TextBox,分别用于输入服务器端的IP、发送的消息,以及一个按钮
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Linq; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; using Thrift.Protocol; using Thrift.Transport; namespace ThriftAndroid { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void btnSend_Click(object sender, EventArgs e) { if (tbUrl.Text == "" || tbIP.Text == "") return; HelloWorldServiceClient.startClient(tbIP.Text, tbUrl.Text); //MessageBox.Show("cmd sended"); } } public class HelloWorldServiceClient { public static void startClient(String ip,String url) { TTransport transport = null; try { transport = new TSocket(ip, 8090, 30000); TProtocol protocol = new TBinaryProtocol(transport); Thrift.Test.ThriftTest.Client client = new Thrift.Test.ThriftTest.Client(protocol); transport.Open(); client.sendMessage(url); } catch (Exception e) { Console.WriteLine(e.StackTrace); } finally { if (transport != null) transport.Close(); } } } }
