I'm new to the forum, so this may have been covered before...
To capture WS-1400-IP data from its web server for logging locally, I wrote the following python code. It runs under OSX, probably Linux, not sure about windows (does windows have curl?).
It works for me, may not work for anyone else.
import subprocess
import re
import time
re.DOTALL # cause re matching for entire string, rather than just per line
IP_address_of_server = "192.168.1.21"
web_page_name_for_data = "http://"+IP_address_of_server+"/"+"livedata.htm"
delay_between_web_page_fetches = 15
vars = ('inTemp','inHumi','AbsPress','RelPress','outTemp','outHumi','windir',
'avgwind','gustspeed','solarrad','uv','uvi','rainofhourly','rainofdaily',
'rainofweekly','rainofmonthly','rainofyearly') # tags for data scraped from the web page
list = {} # contains key: values for web page data
old_list = {} # used to compair previous web page data values (only print when they differ)
def get_data_from_webpage(): # return dict of (data tags : values)
readings = {}
try:
webpage =subprocess.check_output(["curl","-s","-m 3",web_page_name_for_data])
# curl needs -m flag to prevent auto page refresh
except subprocess.CalledProcessError, e:
return "" # web page fetch failed
for var in vars:
match=re.search(var+r'.*value=\"([0123456789\.]+)',webpage)
if match is None:
return "" # on the tage or its value not found
else:
readings[var]=match.group(1)
return readings
def print_file_header_columns():
print "\"date\"",
print ",\"time\"",
for var in vars:
print ",\""+var+"\"",
print "\n"
#let's go
print_file_header_columns()
while (True):
list = get_data_from_webpage()
if cmp(old_list,list) and (list != ""): #only perform if readings have changed or webpage returned ""
tmp = time.strftime("%Y/%m/%d,",time.gmtime())
tmp = tmp+ time.strftime("%H:%M:%S",time.gmtime())
#print tmp
for var in vars:
tmp = tmp+','+list[var]
print tmp
old_list = list
time.sleep(delay_between_web_page_fetches)
