问题描述
我想用python单击一个按钮,该表格的信息会由网页自动填充.用于向按钮发送请求的HTML代码是:
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">我将如何去做? 是否可以仅使用urllib或urllib2单击按钮?还是我需要使用机械化或斜纹呢?
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?
推荐答案使用表单目标并将任何输入作为发布数据发送,如下所示:
Use the form target and send any input as post data like this:
<form target="mysite/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 "mysite/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 "mysite/blah.php?in1=abc" # Then open the new URL which is the same as clicking the submit button s = urllib2.urlopen(form_url)您可以使用 HTMLParser
别忘了用以下代码对任何帖子数据进行urlencode:
And don't forget to urlencode any post data with:
urllib.urlencode(query)
