[python] 가져 오기 오류 : 모듈 이름이 없습니다. urllib2

내 코드는 다음과 같습니다.

import urllib2.request

response = urllib2.urlopen("http://www.google.com")
html = response.read()
print(html)

어떤 도움?

답변

urllib2설명서에 명시된 바와 같이 :

이 urllib2모듈은 Python 3에서 이름이 urllib.request이고 여러 모듈로 나누어 져 있습니다 urllib.error. 이 2to3도구는 소스를 Python 3으로 변환 할 때 가져 오기를 자동으로 조정합니다.

그래서 대신에

from urllib.request import urlopen
html = urlopen("http://www.google.com/").read()
print(html)

방금 편집하는 urllib.urlopen("http://www.google.com/")대신 현재 편집중인 코드 샘플이 잘못되었습니다 urlopen("http://www.google.com/").

답변

Python 2 (테스트 버전 2.7.3 및 2.6.8) 및 Python 3 (3.2.3 및 3.3.2+)에서 작동하는 스크립트의 경우 다음을 시도하십시오.

#! /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())

답변

위의 3.3에서는 저에게 효과가 없었습니다. 대신 이것을보십시오 (YMMV 등)

import urllib.request
url = "http://www.google.com/"
request = urllib.request.Request(url)
response = urllib.request.urlopen(request)
print (response.read().decode('utf-8'))

파이썬 3 :

import urllib.request

wp = urllib.request.urlopen("http://google.com")
pw = wp.read()
print(pw)

파이썬 2 :

import urllib
import sys

wp = urllib.urlopen("http://google.com")
for line in wp:
    sys.stdout.write(line)

각 버전에서 두 가지 코드를 모두 테스트했습니다.

답변

가장 간단한 솔루션 :

Python 3.x에서 :

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)

파이썬 3에서 텍스트 출력을 얻으려면 :

import io
import urllib.request

response = urllib.request.urlopen("http://google.com")
text = io.TextIOWrapper(response)
