ClientForm.AmbiguityError：不止一个控制匹配名称

Question

我在蟒蛇新节目，最近尝试登录私人网站与机械化;我读到这样类似的问题： How to bypass Mechanize "AmbiguityError" in Python，python mechanize handle two parameters with same name，但是这些非可以帮助和有没有反馈解决方案的第二个链接。据我所知，使用br.select_form（nr = 0）应该足以选择第一种形式，但我仍然卡住;我试着用AttributeError改变br.select_form（form的名字）和br.form.find_control（）：'NoneType'对象没有属性'find_control';所有选项都没有成功。 下面的代码和表单的列表可以找到。支持表示赞赏。由于

这是所使用的代码：

br = mechanize.Browser() 
br.set_handle_robots(False) 
cj = cookielib.LWPCookieJar() 
br.set_cookiejar(cj) 
br.select_form(nr=0) 
br.form["username"]= 'Myusername' 
br.form["password"]= 'Mypassword' 
br.submit() 

这些都是形式：

<HiddenControl(smauthreason=0) (readonly)> 
<HiddenControl(clientfp=) (readonly)> 
<HiddenControl(smtryno=0) (readonly)> 
<TextControl(username=)> 
<PasswordControl(password=)> 
<TextControl(username=)> 
<PasswordControl(password=)> 
<TextControl(username=)> 
<PasswordControl(password=)> 
<IgnoreControl(submitFrm=<None>)> 
<HiddenControl(SMAGENTNAME= "deleted by me") (readonly)> 
<HiddenControl(POSTPRESERVATIONDATA=) (readonly)>> 

这是结果：

Traceback (most recent call last):

File "C:\Python27\lib\site-packages\ClientForm.py", line 2895, in __setitem__control = self.find_control(name)

它看起来像只有一种形式从提供的代码和多个用户名，密码字段，这是模糊错误的来源。您可以像选择表单一样使用索引参数，如下所示：

br.select_form(nr=0) 
userone = br.find_control(name="username", nr=0) 
userone.value = "Myusername" 
pwone = br.find_control(name="password", nr=0) 
pwone.value = "Mypassword" 
br.submit()
