我想从 Python 中的 href 标签中分别获取主机名和路径

Question

我有 python 代码，我想从那里分别获取主机名和路径。例如 www.whosebug.com/questions/ask 我想要这样的结果 "host name is: www.whosebug.com and path is: /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'

Answer 1

alinks= link.get('href') 将链接设置为字符串，绝对没有主机名或路径属性，您可以使用 urlparse 获取 path 和主机名:

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

我想从 Python 中的 href 标签中分别获取主机名和路径

I want to get hostname and path separately from href tag In Python
