I'm writing a simple python script to catch messages from gps trackers and write messages to server's db.
# -*- coding: utf-8 -*-
import socket, string
import MySQLdb
def write_message(x):
db = MySQLdb.connect(host="localhost", user="root", passwd="****", db="****", charset='utf8')
cursor = db.cursor()
sql = '''INSERT INTO test(test_c) VALUES ('%(test_c)s') '''%{"test_c":x}
cursor.execute(sql)
db.commit()
db.close()
return x
HOST = ""
PORT = 50007
srv = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
srv.bind((HOST, PORT))
while 1:
print u"Listen to " + str(PORT)
srv.listen(1)
sock, addr = srv.accept()
while 1:
pal = sock.recv(2048)
if not pal:
break
print u"Recieved %s:%s:" % addr, pal
lap = write_message(pal)
sock.close()
To test script I use my home pc with the script
# -*- coding: utf-8 -*-
import socket
HOST = '****'
PORT = 50007
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((HOST, PORT))
mes = u'a'
s.sendall(mes)
s.close()
Everything goes fine and server writes messages to db. With utf-8 they are full of unicode characters and it's ok. But when I use gps tracker I catch some strange messages like "xxSA░7d└╣" ('xx\x11\x01\x03SA\x907d\x84 \x10\x0b2\x01\x00\x01\\xa7\r\n') but the documentation says that messages contain ascii symbols only. I've found that there is "socket.SOCK_RAW" option and tried to use it, but got "socket.error: [Errno 93] Protocol not supported".
Do you know what is the solution?
