TCP实现文本文件上传

开始我的第一篇博客

说说实现文本上传

首先是服务器端要接受客户端传来的数据，第二步将传来的数据写入到服务器的某个文件中，最后向客户端返回上传成功

<span style="font-size:14px;">System.out.println("服务器端启动...");
		ServerSocket server = new ServerSocket(33333);

		Socket s = server.accept();
		System.out.println(s.getInetAddress().getHostAddress()+"连接到服务器端....");

		//创建接收客户端数据的字符读取流
		InputStream in = s.getInputStream();
		BufferedReader br = new BufferedReader(new InputStreamReader(in));

		//创建写入到服务器端的某个文件的字符输出流
		FileWriter fw = new FileWriter("copy.java");
		PrintWriter pw = new PrintWriter(fw,true);

		//创建发送"上传成功"的字符输出流
		OutputStream out =s.getOutputStream();
		PrintWriter pww = new PrintWriter(out,true);

		//循环读取客户端，写入到本地文件
		String line = null;
		while((line = br.readLine())!=null)//因为读取的是客户端，所以读不到null
		{
			pw.println(line);
		}
        //发送"上传成功"
        pww.println("上传成功");

        pw.close();
		s.close();

</span>

接下来就是客户端先读取本地文件，然后向服务器端传入数据，最后接收是否上传成功

Socket  socket = new Socket(InetAddress.getByName("10.0.185.144"),33333);

		//创建读取本地文件的字符读取流
		BufferedReader br =new BufferedReader(new FileReader("Demo1.java"));

        //创建发送给服务器端数据的字符输出流
		OutputStream out = socket.getOutputStream();
		PrintWriter pw =new PrintWriter(out,true);

		//创建读取"上传成功"的字符读取流
		InputStream in = socket.getInputStream();
		BufferedReader brr = new BufferedReader(new InputStreamReader(in));

		//循环读取本地文件，并发送给服务器端
		String line = null;
		while((line = br.readLine())!=null)
		{
			pw.println(line);
		}
		//向服务器端写入结束标记
		socket.shutdownOutput();

		//读取"上传成功"
		System.out.println(brr.readLine());

		br.close();
		socket.close();
