//客户端

package cn.hncu.tcp.upload;import java.io.BufferedReader;import java.io.FileReader;import java.io.IOException;import java.io.InputStreamReader;import java.io.OutputStream;import java.io.PrintWriter;import java.net.Socket;import java.net.UnknownHostException;public class UploadTextClient {public static void main(String[] args) {        try {Socket s=new Socket("127.0.0.1", 10007);//思路：读取本地文件的数据，通过s.getoutputSstream发送出去BufferedReader br=new BufferedReader(new FileReader("tempFiles\\client.txt"));String line=null;//****注意：使用PrintWriter流时必须刷新，否则数据为空,坑了好久PrintWriter pw=new PrintWriter(s.getOutputStream(),true);//打印流，网页中常用。建议不要使用BuffeeredReaderwhile((line=br.readLine())!=null){//out.write(line.getBytes());//System.out.println(line);pw.println(line);}s.shutdownOutput();br.close();//pw.println("over");//System.out.println("到这里来");BufferedReader br2=new BufferedReader(new InputStreamReader(s.getInputStream()));System.out.println(br2.readLine());s.close();br2.close();} catch (UnknownHostException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}        }}

//服务器端
