Python漂亮汤表单输入解析

问题描述：

我的目标是获取所有输入名称和值的列表.将他们配对并提交表格.名称和值是随机的.

My goal is to grab a list of all input names and values. To pair them up and submit the form. The names and values are randomised.

from bs4 import BeautifulSoup # parsing

html = """
<html>
<head id="Head1"><title>Title Page</title></head>
<body>
    <form id="formS" action="login.asp?dx=" method="post">

    <input type=hidden name=qw1NWJOJi/E8IyqHSHA== value='gDcZHY+nV' >
    <input type=hidden name=sfqwWJOJi/E8DFDHSHB== value='kgDcZHY+n' >
    <input type=hidden name=Jsfqw1NdddfDDSDKKSL== value='rNg4pUhnV' >
    </form>

</body>

</html>
"""

html_proc = BeautifulSoup(html)

此位正常工作:

print html_proc.find("input", value=True)["value"]
> gDcZHY+nV

但是，以下语句不起作用或不起作用:

However the following statements don't work or don't work as hoped:

print html_proc.find("input", name=True)["name"]
> TypeError: find() got multiple values for keyword argument 'name'

print html_proc.findAll("input", value=True, attrs={'value'})
> []  

print html_proc.findAll('input', value=True)
> <input name="qw1NWJOJi/E8IyqHSHA==" type="hidden" value="gDcZHY+nV">
> <input name="sfqwWJOJi/E8DFDHSHB==" type="hidden" value="kgDcZHY+n">
> <input name="Jsfqw1NdddfDDSDKKSL==" type="hidden" value="rNg4pUhnV">
> </input></input></input>, <input name="sfqwWJOJi/E8DFDHSHB==" type="hidden" 
> value="kgDcZHY+n">
> <input name="Jsfqw1NdddfDDSDKKSL==" type="hidden" value="rNg4pUhnV">
> </input></input>, <input name="Jsfqw1NdddfDDSDKKSL==" type="hidden" value="rNg4p
> UhnV"></input>

答

您不能使用BeautifulSoup提交表单，但是这是获取名称，值对列表的方法:

You cannot submit a form with BeautifulSoup, but here's how you can get the list of name,value pairs:

print [(element['name'], element['value']) for element in html_proc.find_all('input')]

打印:

[('qw1NWJOJi/E8IyqHSHA==', 'gDcZHY+nV'), 
 ('sfqwWJOJi/E8DFDHSHB==', 'kgDcZHY+n'), 
 ('Jsfqw1NdddfDDSDKKSL==', 'rNg4pUhnV')]
