Here's some code I've recently done.
>From python (on your 'consumer') - this is how I do an HTTP get.
def HTTPGet(url, timeout)
import urllib2
#url = "http://www.google.com";
#timeout = 30
try:
response = urllib2.urlopen(url, None, timeout)
result = response.read()
if result:
return result, None
except urllib2.URLError, ex:
if hasattr(ex, "reason"):
print "HTTPGet: failed to reach a server."
print ex.reason
return None, ex.reason
elif hasattr(ex, "code"):
print "HTTPGet: The server couldn\'t fulfill the request."
print ex.code
return None, ex.code
Now, depending on your needs, 'result' may be just some plain text, xml, or
json - whatever works best for your needs.
This example does an HTTP GET, so of course be aware whatever information
you serve on the other side is publicly available. To secure it you'll
need to work out an authentication scheme. (x-auth headers or whatever)
Hope this helps!
