我想点击一个带有
python的按钮,该表单的信息将自动填满网页.用于向按钮发送请求的HTML代码是：

INPUT type="submit" value="Place a Bid">

我该怎么做呢？
是否可以用urllib或urllib2单击按钮？还是需要使用机械化或斜纹呢？

解决方法

使用表单目标并发送任何输入作为post数据,如下所示：

<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)

您可以使用HTMLParser解析HTML

并且不要忘记urlencode任何发布数据：

urllib.urlencode(query)
