Hi Everybody, Am trying to read a email ids which will be in the form of
links ( on which if we click, they will redirect to outlook with their
respective email ids). And these links are in the HTTPS page, a secured http page. The point is that am able to read some links with HTTP page,
but am not able to read the same when I try with HTTPS. Using the following code from sgmllib am able to read the
links, class MyParser(sgmllib.SGMLParser): def __init__(self):
sgmllib.SGMLParser.__init__(self) self.inside_a =
False self.address = '' def start_a(self,attrs): if DEBUG:
print "start_a"
print attrs for attr,value in
attrs:
if attr == 'href' and value.startswith('mailto:'):
self.address = value[7:] self.inside_a =
True def end_a(self): if DEBUG:
print "end_a" if self.address:
print '"%s" <%s>' % (self.nickname, self.address)
mailIdList.append(self.address)
self.inside_a =
False self.address =
self.nickname = '' def handle_data(self,data): if self.inside_a:
self.nickname = data And for the proxy authentication and the https handler am
using the following lines of code
authinfo = urllib2.HTTPBasicAuthHandler()
proxy_support = urllib2.ProxyHandler ({"http" :
"http://user:password@proxyname:port"})
opener = urllib2.build_opener(proxy_support, authinfo, urllib2.HTTPSHandler)
urllib2.install_opener(opener) Then am trying to call the parser for the links in a
particular https page which will be given as a command line argument. Which
will read me all the links in that page. p = MyParser() for ln in urllib2.urlopen( sys.argv[1] ): p.feed(ln) p.close() NOTE : I have installed python with _ssl
support also. So with this code am able to read the links with HTTP page
but not for the HTTPS page. AM NOT GETTING ANY ERRORS EITHER BUT ITS
NOT READING THE LINKS, THAT ARE PRESENT IN THE GIVEN HTTPS PAGE Could you please tell me am I doing some thing wrong in the
above code for any of the handlers. I have got struck here from so many days, please give me the
solution for this. Thanks and regards YOGI |
