python - 用 Mechanize 打开网页后，如何继续提交

Question

import mechanize
br = mechanize.Browser()
br.open('someurl.com')
br.select_form(nr=0)
br.form['user'] = 'myname'
br.form['pw'] ='pw'
req=br.submit()

提交后，我登录了一个新页面，这进一步要求我单击“下一步”

<input type="submit" value="   Next   " name="B1"> <input type="reset" value="    Clear    " name="B2"></td>

我该如何继续？

Answer 1

因此，解决方案非常简单，因为一旦您拥有浏览器实例，它就可以像真正的浏览器一样工作；在这个问题中，您可以在第一次成功提交后再次提交。

所以，这是原始代码:

import mechanize
br = mechanize.Browser()
br.open('someurl.com')
br.select_form(nr=0)
br.form['user'] = 'myname'
br.form['pw'] ='pw'
req=br.submit()

然后重复您所做的以进入下一页(以下是完整的解决方案):

import mechanize
br = mechanize.Browser() # now you are at first login page
br.open('someurl.com')
br.select_form(nr=0)    # select the form from the first login page
br.form['user'] = 'myname'
br.form['pw'] ='pw'
req=br.submit() # now you are at second login page
br.select_form(nr=0) # select the form from the second login page
br.form['user'] = 'myname'
br.form['pw'] ='pw'
req=br.submit()
