Ecco il mio codice:
import urllib2.request
response = urllib2.urlopen("http://www.google.com")
html = response.read()
print(html)
Qualsiasi aiuto?

Risposte:
Come indicato nella urllib2
documentazione :
Il
urllib2
modulo è stato suddiviso su più moduli in Python 3 denominatourllib.request
eurllib.error
. Lo2to3
strumento adatta automaticamente le importazioni durante la conversione delle fonti in Python 3.
Quindi dovresti invece dirlo
from urllib.request import urlopen
html = urlopen("http://www.google.com/").read()
print(html)
L'esempio di codice corrente, ora modificato, non è corretto perché stai dicendo urllib.urlopen("http://www.google.com/")
invece che solo urlopen("http://www.google.com/")
.
urllib.request
e non urllib2.request
. I moduli urllib
e urllib2
di Python 2.x sono stati combinati nel urllib
modulo in Python 3.
Per uno script che funziona con Python 2 (versioni testate 2.7.3 e 2.6.8) e Python 3 (3.2.3 e 3.3.2+) provare:
#! /usr/bin/env python
try:
# For Python 3.0 and later
from urllib.request import urlopen
except ImportError:
# Fall back to Python 2's urllib2
from urllib2 import urlopen
html = urlopen("http://www.google.com/")
print(html.read())
Quanto sopra non ha funzionato per me in 3.3. Prova questo invece (YMMV, ecc.)
import urllib.request
url = "http://www.google.com/"
request = urllib.request.Request(url)
response = urllib.request.urlopen(request)
print (response.read().decode('utf-8'))

Python 3:
import urllib.request
wp = urllib.request.urlopen("http://google.com")
pw = wp.read()
print(pw)
Python 2:
import urllib
import sys
wp = urllib.urlopen("http://google.com")
for line in wp:
sys.stdout.write(line)
Mentre ho testato entrambi i codici nelle rispettive versioni.
La più semplice di tutte le soluzioni:
In Python 3.x:
import urllib.request
url = "https://api.github.com/users?since=100"
request = urllib.request.Request(url)
response = urllib.request.urlopen(request)
data_content = response.read()
print(data_content)
In python 3, per ottenere l'output del testo:
import io
import urllib.request
response = urllib.request.urlopen("http://google.com")
text = io.TextIOWrapper(response)
Ha funzionato per me in python3:
import urllib.request
htmlfile = urllib.request.urlopen("http://google.com")
htmltext = htmlfile.read()
print(htmltext)
urllib.urlopen("http://www.google.com/")
invece che solourlopen("http://www.google.com/")
