Python + Mechanize不使用Delicious

Question

我正在使用Mechanize和Beautiful汤从Delicious中删除一些数据

from mechanize import Browser
from BeautifulSoup import BeautifulSoup

mech = Browser()
url = "http://www.delicious.com/varunsrin"
page = mech.open(url)
html = page.read()

soup = BeautifulSoup(html)
print soup.prettify()

这适用于我抛出它的大多数网站,但是使用以下输出在Delicious上失败

Traceback (most recent call last):  
File "C:\Users\Varun\Desktop\Python-3.py",
line 7, in <module>
    page = mech.open(url)

Answer 1

从这里获取一些使用python + mechanize模拟浏览器的技巧.添加addheaders并且set_handle_robots似乎是最低要求.使用下面的代码,我得到输出:

from mechanize import Browser, _http
from BeautifulSoup import BeautifulSoup

br = Browser()    
br.set_handle_robots(False)
br.addheaders = [('User-agent', 'Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.1) Gecko/2008071615 Fedora/3.0.1-1.fc9 Firefox/3.0.1')]

url = "http://www.delicious.com/varunsrin"
page = br.open(url)
html = page.read()

soup = BeautifulSoup(html)
print soup.prettify()
