我是 python 的新手,目前我正在开发一个 GPS 跟踪器,它使用 Arduino Uno 与谷歌地图交互。我收到此错误,它不允许我为我的 tcpServer 运行 .py 脚本,这是整个脚本。
#!/usr/bin/env python
import socket
import MySQLdb
TCP_IP = 'my machine IP'
TCP_PORT = 32000
BUFFER_SIZE = 40
# ClearDB. Deletes the entire tracking table
def ClearDB(curs,d ):
curs.execute ("""
INSERT INTO gmaptracker (lat, lon)
VALUES (0.0,0.0)""")
d.commit()
# Connect to the mySQL Database
def tServer():
try:
db = MySQLdb.connect (host = "my host",
user = "my user",
passwd = "my password",
db = "gmap" )
except MySQLdb.Error, e:
print "Error %d: %s" %(e.args[0], e.args[1])
sys.exit(1);
cursor = db.cursor()
# Start with a fresh tracking table
ClearDB(cursor,db)
# Set up listening Socket
try:
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1)
s.bind((TCP_IP, TCP_PORT))
print "Listening...."
s.listen(1)
conn, addr = s.accept()
print 'Accepted connection from address:', addr
except socket.error (message):
if s:
s.close()
print "Could not open socket: " + message
cursor.close()
conn.close()
db.close()
sys.exit(1)
try:
while 1:
data = conn.recv(BUFFER_SIZE)
if not data:break
str1,str2 = data.split("Long: ")
str1 = str1.split("Lat: ")[1]
latitude = float(str1)
longitude = float(str2)
cursor.execute ("""
INSERT INTO gmaptracker (lat, lon)
VALUES (%s,%s)""", (latitude,longitude))
db.commit()
except KeyboardInterrupt:
ClearDB(cursor,db);
cursor.close()
conn.close()
db.close()
if __name__ == '__main__':
tServer()
这是我得到的错误
Traceback (most recent call last):
File "tcpServer.py", line 79, in <module>
tServer()
File "tcpServer.py", line 48, in tServer
except socket.error(message):
NameError: global name 'message' is not defined
如果有人能帮我解决这个问题,我将不胜感激,因为我说我是 python 的新手,如果有帮助的话,我也在运行 python 2.7。提前致谢
