本文實例講述了python服務(wù)器與android客戶端socket通信的方法。分享給大家供大家參考。具體實現(xiàn)方法如下：
首先，服務(wù)器端使用python完成，下面為python代碼：
復(fù)制代碼
代碼如下:
#server.py?
import socket?
def getipaddrs(hostname):#只是為了顯示IP，僅僅測試一下?
??? result = socket.getaddrinfo(hostname, None, 0, socket.SOCK_STREAM)?
??? return [x[4][0] for x in result]?
?
host = ''#為空代表為本地host?
hostname = socket.gethostname()?
hostip = getipaddrs(hostname)?
print('host ip', hostip)#應(yīng)該顯示為：127.0.1.1?
port = 9999???? # Arbitrary non-privileged port?
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)?
s.bind((host, port))?
s.listen(4)?
while True:?
??? conn, addr = s.accept()?
??? print('Connected by', addr)?
??? data = conn.recv(1024)?
??? if not data: break?
??? conn.sendall(data)#把接收到數(shù)據(jù)原封不動的發(fā)送回去?
??? print('Received', repr(data))?
??? conn.close()
import socket?
def getipaddrs(hostname):#只是為了顯示IP，僅僅測試一下?
??? result = socket.getaddrinfo(hostname, None, 0, socket.SOCK_STREAM)?
??? return [x[4][0] for x in result]?
?
host = ''#為空代表為本地host?
hostname = socket.gethostname()?
hostip = getipaddrs(hostname)?
print('host ip', hostip)#應(yīng)該顯示為：127.0.1.1?
port = 9999???? # Arbitrary non-privileged port?
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)?
s.bind((host, port))?
s.listen(4)?
while True:?
??? conn, addr = s.accept()?
??? print('Connected by', addr)?
??? data = conn.recv(1024)?
??? if not data: break?
??? conn.sendall(data)#把接收到數(shù)據(jù)原封不動的發(fā)送回去?
??? print('Received', repr(data))?
??? conn.close()
下面是Android代碼：
復(fù)制代碼
代碼如下:

??????????? //send output msg?

??? private void runTcpClientAsService() {?
??????? Intent lIntent = new Intent(this.getApplicationContext(), TcpClientService.class);?
??????? this.startService(lIntent);?
??? }?

}
安卓代碼中要注意的就是服務(wù)器的地址要寫對，而且要保證服務(wù)器是可以被你的網(wǎng)段訪問的。
希望本文所述對大家的Python程序設(shè)計有所幫助。
