Hi all,

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
