如何在python中使用机械化单击？

Question

i have a form which is used for authentication. but in this form there are no submit button but it has used an <input> as a button . now i am confused how to click this type of button with MECHANIZE.

till now i had done this:

import urllib
import re
import mechanize
from base64 import b64encode

and can this be done in Java script?

br = mechanize.Browser()


response = br.open("http://xyz.com");
#print response.code
#print response.geturl()

br.select_form("login")
br.form['j_username'] = 'user'
br.form['j_password'] = 'pass'

Answer 1

That's not an error. Read the response - it's a filelike object.

br.select_form("login")
br.form['j_username'] = 'xyz'
br.form['j_password'] = 'pass'
pag2 = br.submit()
html = pag2.read()
print html

Answer 2

This is a submit button. A submit button in HTML is by definition an <input> element of type submit .
