python thread prob after build
- by Apache
hi expert, i'm having task to scan wifi at specific interval and send it to the server, i've it in python and its works fine when i run manually, then build it to package and when run there is no progress at all, i already ask this question before at http://stackoverflow.com/questions/2735410/python-scritp-problem-once-build-and-package-it,
then, i re-modify my code as below, then i found that thread is not functioning once i build,
#!/usr/bin/env python
import subprocess,threading,...
configFile = open('/opt/Jemapoh_Wifi/config.txt', 'r')
url = configFile.readline().strip()
intervalTime = configFile.readline().strip()
status = configFile.readline().strip()
print "url "+url
print "intervalTime "+intervalTime
print "Status "+status.strip()
def getMacAddress():
proc = subprocess.Popen('ifconfig -a wlan0 | grep HWaddr | sed \'/^.*HWaddr */!d; s///;q\'', shell=True, stdout=subprocess.PIPE, )
macAddress = proc.communicate()[0].strip()
return macAddress
def getTimestamp():
from time import strftime
timeStamp = strftime("%Y-%m-%d %H:%M:%S")
return timeStamp
def scanWifi():
try:
print "Scanning..."
proc = subprocess.Popen('iwlist scan 2>/dev/null', shell=True, stdout=subprocess.PIPE, )
stdout_str = proc.communicate()[0]
stdout_list=stdout_str.split('\n')
essid=[]
rssi=[]
preQuality=[]
for line in stdout_list:
line=line.strip()
match=re.search('ESSID:"(\S+)"',line)
if match:
essid.append(match.group(1))
match=re.search('Quality=(\S+)',line)
if match:
preQuality.append(match.group(1))
for qualityConversion in preQuality:
qualityConversion = qualityConversion.split()[0].split('/')
temp = str(int(round(float(qualityConversion[0]) / float(qualityConversion[1]) * 100))).rjust(2)
rssi.append(temp)
dataToPost = '{"userId":"' + getMacAddress() + '","timestamp":"' + getTimestamp() + '","wifi":['
for no in range(len(essid)):
dataToPost += '{"ssid":"' + essid[no] + '","rssi":"' + rssi[no] + '"}'
if no+1 == len(essid):
pass
else:
dataToPost += ','
dataToPost += ']}'
query_args = {"data":dataToPost}
request = urllib2.Request(url)
request.add_data(urllib.urlencode(query_args))
request.add_header('Content-Type', 'application/x-www-form-urlencoded')
print "Waiting for server response..."
print urllib2.urlopen(request).read()
print "Data Sent @ " + getTimestamp()
print "------------------------------------------------------"
t = threading.Timer(int(intervalTime), scanWifi).start()
except Exception, e:
print e
t = threading.Timer(int(intervalTime), scanWifi)
t.start()
once build, its not reaching the thread, do can anyone help, why the thread is not working after build
thanks
