我正在尝试与客户端发送一个文件(作为字节数组发送的图像),然后服务器应该接收到所述字节数组以进一步使用它。但是,当我单击“发送”以发送图像时,文件传输开始(因为我在桌面上收到了一个 sentImage.jpg),但由于某种原因我无法弄清楚并且图像永远不会正确发送。
这是从服务器接收的部分(它已经接受了连接):
public void run(){
try {
byte[] receivedData = new byte[1024];
BufferedInputStream bis = new BufferedInputStream(client.getInputStream());
// while(bis.read() != -1){
s.acquireUninterruptibly();
BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream("C:\\Users\\Admin\\Desktop\\sentImage.jpg"));
while ((incoming = bis.read(receivedData)) != -1) {
bos.write(receivedData, 0, incoming);
}
s.release();
n.release();
bis.close();
bos.flush();
// }
} catch (IOException e) {
e.printStackTrace();
}
}
客户在这里发送:
public void sendImageResult() {
new Thread(new Runnable() {
public void run() {
try {
int inside = 0;
Socket socket = new Socket("localhost", 4444);
File myImageFile = new File("C:\\Users\\Admin\\Desktop\\test.jpg");
BufferedInputStream bis = new BufferedInputStream(new FileInputStream(myImageFile));
BufferedOutputStream bos = new BufferedOutputStream(socket.getOutputStream( ));
byte[] byteArray = new byte[1024];
while ((inside = bis.read(byteArray)) != -1){
bos.write(byteArray,0,inside);
}
bis.close();
bos.flush();
} catch (UnknownHostException ex) {
System.out.println("No se pudo establecer la conexión.");
ex.printStackTrace();
} catch (FileNotFoundException fnf){
fnf.printStackTrace();
} catch(IOException ioe){
ioe.printStackTrace();
}
}
}).start();
}
