小弟我目前在做一個android與pc的client-server架構之傳檔程式
android為client
pc為server
在android傳檔到PC的情況下
模擬器測試結果正常
但實機測試卻產生資料遺失的情況(原檔132KB 傳過去變131KB)
導致檔案損毀
以下是我android的程式碼
File file = new File(SDCardpath.getAbsolutePath()+"/"+filename);
PrintStream printStream = new PrintStream(socket.getOutputStream());
printStream.println(file.getName());
BufferedInputStream inputStream = new BufferedInputStream
(new FileInputStream(file));
int readin;
while((readin = inputStream.read()) != -1) {
printStream.write(readin);
}
printStream.flush();
printStream.close();
inputStream.close();
socket.close();
我懷疑是第3行我先傳file.getName()才會導致這個問題
以下是java的程式碼
int port = Integer.parseInt(args[0]);
System.out.println("Server IP"+InetAddress.getLocalHost().getHostAddress());
System.out.println("簡易檔案接收...");
System.out.printf("將接收檔案於連接埠: %d%n", port);
ServerSocket ssocket = new ServerSocket(port);
while(true) {
System.out.println("傾聽中....");
Socket skt = ssocket.accept();
System.out.printf("與 %s 建立連線%n",skt.getInetAddress().toString());
BufferedReader filename = new BufferedReader
(new InputStreamReader(skt.getInputStream()));
BufferedInputStream in = new BufferedInputStream(skt.getInputStream());
BufferedOutputStream out = new BufferedOutputStream
(new FileOutputStream(filename.readLine())); //接收android第3行傳來的檔案
//名稱,然後開檔
int readin;
while((readin = in.read()) != -1)
{
out.write(readin);
Thread.yield();
}
out.flush();
out.close();
in.close();
skt.close();
System.out.println("\n檔案接收完畢！");
}
不知道怎麼修正這問題
懇請各位大大幫忙
感謝~~
