Question

我是python中的新编程，最近尝试使用mechanize登录私人网站;我读过类似的问题： How to bypass Mechanize "AmbiguityError" in Python，python mechanize handle two parameters with same name，但是这些中没有一个可以提供帮助，并且没有针对第二个链接的解决方案的反馈。据我所知，使用br.select_form（nr = 0）应该足以选择第一个表格但是我仍然卡住;我尝试过更改br.select_form（表单名称）和br.form.find_control（）以及AttributeError：＆＃39; NoneType＆＃39;对象没有属性＆＃39; find_control＆＃39 ;;所有选项都没有成功。可以找到下面的代码和表单列表。支持表示赞赏。感谢

这是使用的代码：

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)>>

结果如下：

Traceback (most recent call last):
File "C:/Documents/JMARTINEZ/My Various/PythonPrograms/Mechanize.py",line 77, in <module> br.form["username"]= username
 File "C:\Python27\lib\site-packages\ClientForm.py", line 2895, in __setitem__control = self.find_control(name)
 File "C:\Python27\lib\site-packages\ClientForm.py", line 3222, in find_control return self._find_control(name, type, kind, id, label, predicate, nr)
 File "C:\Python27\lib\site-packages\ClientForm.py", line 3304, in _find_control raise AmbiguityError("more than one control matching "+description)ClientForm.AmbiguityError: more than one control matching name 'username'

看起来提供的代码只有一个表单，多个用户名，密码字段是Ambiguous错误的来源。你可以使用index参数来选择表单，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()

ClientForm.AmbiguityError：多个控件匹配名称
