蟒蛇 +机械化不与 Delicious 合作

我正在使用 Mechanize 和 Beautiful soup 来从 Delicious 上刮掉一些数据，

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()

这适用于我扔给它的大多数网站，但在 Delicious 上失败，输出如下

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

line 203, in open
    return self._mech_open(url, data, timeout=timeout)   File

I'm using Mechanize and Beautiful soup to scrape some data off Delicious

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()

This works for most sites I throw it at, but fails on Delicious with the following output

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

从此处获取使用 python+mechanize 模拟浏览器的一些技巧。添加 addheaders 和 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()

Take some of the tips for emulating a browser with python+mechanize from here. Adding addheaders and set_handle_robots appears to be the minimum required. With the code below, I get output:

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()
