I want to click a button with python, the info for the form is automatically filled by the webpage. the HTML code for sending a request to the button is:
INPUT type="submit" value="Place a Bid">
How would I go about doing this? Is it possible to click the button with just urllib or urllib2? Or will I need to use something like mechanize or twill?
Use the form target and send any input as post data like this:
<form target="http://mysite.com/blah.php" method="GET">
......
......
......
<input type="text" name="in1" value="abc">
<INPUT type="submit" value="Place a Bid">
</form>
Python:
# parse the page HTML with the form to get the form target and any input names and values... (except for a submit and reset button)
# You can use XML.dom.minidom or htmlparser
# form_target gets parsed into "http://mysite.com/blah.php"
# input1_name gets parsed into "in1"
# input1_value gets parsed into "abc"
form_url = form_target + "?" + input1_name + "=" + input1_value
# form_url value is "http://mysite.com/blah.php?in1=abc"
# Then open the new URL which is the same as clicking the submit button
s = urllib2.urlopen(form_url)
You can parse the HTML with HTMLParser
And don't forget to urlencode any post data with:
