Bir echo sunucusundan ve aşağıdaki kodla bir android istemcisinden oluşan bir sınamayı çalıştırmayı denediğimde, her zaman "msn kapalı" özel durum mesajı alıyorum. Bu kod sadece sunucuya msg gönderebilir ve sunucudan msg alabilir, fakat aynı anda her ikisini de yapmak isterseniz, işe yaramıyor ... Neden bu tür bir soruna yol açacağını merak ediyorum. ve eğer ilk e-posta sunucusunaAndroid Socket Exception "soket kapalı"
'a msg göndermek ve sonra eko sunucusundan msg gönderebilmek için bunu nasıl düzeltmeliyim?
// Server IP address
InetAddress serverIp;
// try to connect Server
try {
// set up server IP address
serverIp = InetAddress.getByName("192.168.17.1");
// set up port
int serverPort=12345;
// initiate socket connection
Socket clientSocket=new Socket(serverIp,serverPort);
BufferedOutputStream out = new BufferedOutputStream(clientSocket.getOutputStream());
out.write("Send From Android1111, stitch ".getBytes());
out.flush();
//wait to receive Server's msg
BufferedReader br =new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
total.toString();*/
// Display received msg with Toast
Toast.makeText(getApplicationContext(), br.readLine(), Toast.LENGTH_SHORT).show();
//close connection
clientSocket.close();
// out.close();
// out = null;
} catch (IOException e) {
// display exception with Toast
Toast.makeText(getApplicationContext(),e.toString(), Toast.LENGTH_SHORT).show();
}
maalesef hala ... çalışmıyor Ben senin talimat takip ve kod değiştirin: Yardımcısı'nın kolaylık
// set up Server IP address
serverIp = InetAddress.getByName("192.168.2.2");
// set up Server port
int serverPort=12345;
// initiate socket connection
Socket clientSocket=new Socket(serverIp,serverPort);
// open input and output stream
OutputStream out = clientSocket.getOutputStream();
InputStream in = clientSocket.getInputStream();
//send msg
out.write("Send From Android1111, bitch ".getBytes());
// receive msg from server
byte[] buffer = new byte[in.available()];
in.read(buffer);
String rMsg = new String(buffer);
Toast.makeText(getApplicationContext(), rMsg, Toast.LENGTH_LONG).show();
//close input and output stream
in.close();
out.close();
//關閉連線
clientSocket.close();
} catch (IOException e) {
// 出錯後顯示錯誤訊息Toast
Toast.makeText(getApplicationContext(),e.toString(), Toast.LENGTH_SHORT).show();
}
, burada sunucu bölümü için kod yazılı piton : Hatalı sırada doğru şeyleri yaptığınızı farz ediyorum.
# Practice Echo Server Program written in Python
import socket
# host = '' means it binds to any available interface
host = ''
port = 12345
# socket() function returns a socket object whose methods implement the various socket system calls.
s = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
# Bind the socket to address.
s.bind((host,port))
# Listen for connections made to the socket. The backlog argument specifies
# the maximum number of queued connections and should be at least 0;
# the maximum value is system-dependent (usually 5), the minimum value is forced to 0.
s.listen(5)
# Accept a connection. The socket must be bound to an address and listening for
# connections. The return value is a pair (conn, address) where conn is a new socket
# object usable to send and receive data on the connection, and address is the address
# bound to the socket on the other end of the connection.
conn, addr = s.accept()
print 'Connected by', addr
# Receive data from the socket. The return value is a string representing the data received.
# The maximum amount of data to be received at once is specified by bufsize. See the Unix
# manual page recv(2) for the meaning of the optional argument flags; it defaults to zero.
# Note For best match with hardware and network realities, the value of bufsize should be
# a relatively small power of 2, for example, 4096.
while 1:
data = conn.recv(1024)
if not data: break
print 'received data is : ', repr(data)
conn.send(data)
conn.close()
