Problema con python para accesar página https Desde hace algunos días tengo un problema accesando a https://www.sicop-sep.hacienda.gob.mx/ por medio de python.
Busco obtener el código de retorno para saber si está o no funcionando, sin embargo, arroja un error y no tengo idea del por qué ocurre.
El código tiene una función que sigue los redireccionamientos y funciona bien con otras páginas https (probé https://www.eff.org/https-everywhere/ y https://www.cia.gov/kids-page/index.html), pero, en la que me marca error, no he tenido suerte. De hecho, sólo he podido entrar a la página usando Firefox 3.x.
¿Hay algo equivocado en el código o para ese tipo de páginas debería de usar algo más?
Agradecezco de antemano su tiempo.
Código:
Al ejecutar el código arroja lo siguiente:
import urllib.request
import http.client
import urllib.parse
from urllib.parse import urlparse
def resolve_http_redirect(url, depth=0):
if depth > 10:
raise Exception("Redirected "+depth+" times, giving up.")
o = urllib.parse.urlparse(url,allow_fragments=True)
print(o)
conn = http.client.HTTPSConnection(o.netloc)
path = o.path
print (path)
if o.query:
path +='?'+o.query
conn.request("HEAD", path)
res = conn.getresponse()
headers = dict(res.getheaders())
if 'location' in headers and headers['location'] != url:
return resolve_http_redirect(headers['location'], depth+1)
else:
return url
url_https="https://www.sicop-sep.hacienda.gob.mx/"
host = urlparse(url_https)[1]
print(host)
req = ''.join(urlparse(url_https)[2:])
print(req)
conn = http.client.HTTPSConnection(host)
conn.request('HEAD', req)
resp = conn.getresponse()
print(resp.status)
print(resp.reason)
print(" ")
print(resp.msg)
answer=resolve_http_redirect(url_https)
print(answer)
