我有python代码,我希望分别获取主机名和路径。例如www.stackoverflow.com/questions/ask我想要这样的结果"主机名是:www.stackoverflow.com,路径是:/ questions / ask"
这是我的python代码:
import urllib
from bs4 import BeautifulSoup
import urlparse
import mechanize
import socket
import errno
import io
from nyt4 import articalText
url = "http://www.nytimes.com/section/health"
br = mechanize.Browser()
br.set_handle_equiv(False)
htmltext = br.open(url)
#htmltext = urllib.urlopen(url).read()
soup = BeautifulSoup(htmltext)
maindiv = soup.findAll('section', attrs={'class':'health-collection collection'})
for links in maindiv:
atags = soup.findAll('a',href=True)
for link in atags:
alinks= link.get('href')
print alinks.hostname
print alinks.path
但是这段代码给了我这个错误:
Traceback (most recent call last):
File "<pyshell#18>", line 1, in <module>
execfile("nytimes/test2.py")
File "nytimes/test2.py", line 21, in <module>
print alinks.hostname
AttributeError: 'unicode' object has no attribute 'hostname'
答案 0 :(得分:0)
alinks= link.get('href')
设置alink到一个绝对没有主机名或路径属性的字符串,您可以使用urlparse来获取路径和主机名< / EM>:
import mechanize
from bs4 import BeautifulSoup
from urlparse import urlparse
url = "http://www.nytimes.com/section/health"
br = mechanize.Browser()
br.set_handle_equiv(False)
htmltext = br.open(url)
#htmltext = urllib.urlopen(url).read()
soup = BeautifulSoup(htmltext)
maindiv = soup.find_all('section', attrs={'class':'health-collection collection'})
for links in maindiv:
atags = soup.find_all('a',href=True)
for link in atags:
alinks = urlparse(link.get('href'))
print alinks.hostname
print alinks.path
