2.x版本的python可以直接使用import urllib来进行操作,但是3.x版本的python使用的是import urllib.request来进行操作,下面是简单的例子:
===============================================================================
# get code of given URL as html text string
# Python3 uses urllib.request.urlopen()
# instead of Python2‘s urllib.urlopen() or urllib2.urlopen()
import urllib.request
fp = urllib.request.urlopen("http://www.python.org")
mybytes = fp.read()
# note that Python3 does not read the html code as string
# but as html code bytearray, convert to string with
mystr = mybytes.decode("utf8")
fp.close()
print(mystr)
================================================================================
# get the code of a given URL as html text string
# Python3 uses urllib.request.urlopen()
# get the encoding used first
# tested with Python 3.1 with the Editra IDE
import urllib.request
def extract(text, sub1, sub2):
"""
extract a substring from text between first
occurances of substrings sub1 and sub2
"""
return text.split(sub1, 1)[-1].split(sub2, 1)[0]
fp = urllib.request.urlopen("http://www.python.org")
mybytes = fp.read()
encoding = extract(str(mybytes).lower(), ‘charset=‘, ‘"‘)
print(‘-‘*50)
print( "Encoding type = %s" % encoding )
print(‘-‘*50)
if encoding:
# note that Python3 does not read the html code as string
# but as html code bytearray, convert to string with
mystr = mybytes.decode(encoding)
print(mystr)
else:
print("Encoding type not found!")
fp.close()
