基於socket的上傳下載（Java）精簡版

很簡單的一個例子，沒有介面只有代碼。

伺服器端代碼

package server;import java.io.BufferedInputStream;import java.io.BufferedOutputStream;import java.io.DataInputStream;import java.io.DataOutputStream;import java.io.FileInputStream;import java.net.ServerSocket;import java.net.Socket;public class AndroidServer implements Runnable {private ServerSocket serverSocket = null;private DataInputStream is;public void run() {if (serverSocket == null) {try {serverSocket = new ServerSocket(5926);} catch (Exception e) {e.printStackTrace();}}try {Socket socket = serverSocket.accept();is = new DataInputStream(new BufferedInputStream(new FileInputStream("D:\\test.mp4"))); // 把需要上傳的檔案，放入InputStreamDataOutputStream os = new DataOutputStream(new BufferedOutputStream(socket.getOutputStream())); // 初始化socket的OutputStreamint count;byte[] buffer = new byte[1024];while ((count = is.read(buffer, 0, buffer.length)) != -1) { // 把檔案放入socket的OutputStream中os.write(buffer, 0, count);}os.flush();serverSocket.close();socket.close();} catch (Exception e) {e.printStackTrace();}}public static void main(String[] args) {Thread desktopServerThread = new Thread(new AndroidServer()); // 啟動服務desktopServerThread.start();}}

用戶端代碼

import java.io.BufferedOutputStream;import java.io.DataInputStream;import java.io.DataOutputStream;import java.io.File;import java.io.FileOutputStream;import java.net.Socket;public class test {public static void main(String[] args) {try {Socket socket = new Socket("192.168.0.228", 5926);DataInputStream dis = new DataInputStream(socket.getInputStream()); // 擷取socket中的InputStreamDataOutputStream os = new DataOutputStream(new BufferedOutputStream(new FileOutputStream(new File("D:\\fuck")))); // 初始化OutputStreamint count = 0;byte[] buffer = new byte[1024];while ((count = dis.read(buffer)) != -1) { // 把socket中的InputStream放入OutputStreamos.write(buffer, 0, count);}os.close();socket.close(); // 上傳完成，關閉socket} catch (Exception e) {e.printStackTrace();} finally {}}}
