hi im building a scraper using python 2.5 and beautifulsoup but im stuble upon a problem ... part of the web page is generating a开发者_运维问答fter user click on some button, whitch start an ajax request by calling specific javacsript function using proper parameters
is there a way to simulate user interaction and get this result? i come across a mechanize module but it seems to me that this is mostly used to work with forms ...
i would appreciate any links or some code samples thanks
ok so i have figured it out ... it was quite simple after i realised that i could use combination of urllib, ulrlib2 and beautifulsoup
import urllib, urllib2
from BeautifulSoup import BeautifulSoup as bs_parse
data = urllib.urlencode(values)
req = urllib2.Request(url, data)
res = urllib2.urlopen(req)
page = bs_parse(res.read())
No, you can't do that easily. AFAIK your options are, easiest first:
- Read the AJAX javascript code yourself, as a human programmer, understand it, and then write python code to simulate the AJAX calls by hand. You can also use some capture software to capture requests/responses made live and try to reproduce them with code;
- Use selenium or some other browser automation tool to fetch the page on a real web browser;
- Use some python javascript runner like spidermonkey or pyv8 to run the javascript code, and hook it to your copy of the HTML dom;
