打开一个网页，用机械化，我如何能继续提交

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() 

后提交后，我登录了新的一页，这进一步要求我点击“下一步”

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

我怎么能继续上？

Answer 1

因此，该解决方案非常简单，因为一旦您拥有浏览器实例，它就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，这里是原代码：

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() 

然后重复你做了什么，以移动到下一个页面（下面是完整的解决方案）：

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()
