Python won't refresh URL to receive new forex ticker data
I am trying to save updated Forex ticker data from this website: http://fo开发者_如何学Crex.offers4u.biz/TickDBReadDB.php?p=EURUSD
just hit refresh to update the ticker.
when I use my little python script, it saves the text once, but if i run it again, it makes a new file with the same old data. How can I add a "cachebreaker" so that python can read the new data from the old URL?
import urllib2, time
filename = 'EURUSD ' + str(time.asctime()) + '.txt'
myfile = open(filename, 'w')
page = urllib2.urlopen("http://forex.offers4u.biz/TickDBReadDB.php?p=EURUSD?")
for line in page:
myfile.write(line)
myfile.close()
page.close()
urllib2 doesn't do any caching. Are you going through a proxy? Or the server may be caching.
Try using a Cache-Control header described here, section 14.9
EDIT: Mind you, the most recent data on that page is from 2009.11.16 20:47:37. Are you sure it's still being actively updated?
