目前正在使用 Mechanize 提交一些表单

这是我当前的 sn-p 代码：

add_control = br.form.find_control(name='CRN_IN', id='crn_id1')

一共有10个文本框，我用下面的代码打印出来：

for form in br.forms():                                                   
    print "Form name:", form.name                                         
    print form

这是输出：

  <TextControl(CRN_IN=)>
  <HiddenControl(assoc_term_in=) (readonly)>
  <HiddenControl(start_date_in=) (readonly)>
  <HiddenControl(end_date_in=) (readonly)>
  <HiddenControl(RSTS_IN=WR) (readonly)>

  <TextControl(CRN_IN=)>
  <HiddenControl(assoc_term_in=) (readonly)>
  <HiddenControl(start_date_in=) (readonly)>
  <HiddenControl(end_date_in=) (readonly)>
  <HiddenControl(RSTS_IN=WR) (readonly)>

  <TextControl(CRN_IN=)>
  <HiddenControl(assoc_term_in=) (readonly)>
  <HiddenControl(start_date_in=) (readonly)>
  <HiddenControl(end_date_in=) (readonly)>
  <HiddenControl(RSTS_IN=WR) (readonly)>

  <TextControl(CRN_IN=)>
  <HiddenControl(assoc_term_in=) (readonly)>
  <HiddenControl(start_date_in=) (readonly)>
  <HiddenControl(end_date_in=) (readonly)>
  <HiddenControl(RSTS_IN=WR) (readonly)>

  <TextControl(CRN_IN=)>
  <HiddenControl(assoc_term_in=) (readonly)>
  <HiddenControl(start_date_in=) (readonly)>
  <HiddenControl(end_date_in=) (readonly)>
  <HiddenControl(RSTS_IN=WR) (readonly)>

  <TextControl(CRN_IN=)>
  <HiddenControl(assoc_term_in=) (readonly)>
  <HiddenControl(start_date_in=) (readonly)>
  <HiddenControl(end_date_in=) (readonly)>
  <HiddenControl(RSTS_IN=WR) (readonly)>

  <TextControl(CRN_IN=)>
  <HiddenControl(assoc_term_in=) (readonly)>
  <HiddenControl(start_date_in=) (readonly)>
  <HiddenControl(end_date_in=) (readonly)>
  <HiddenControl(RSTS_IN=WR) (readonly)>

  <TextControl(CRN_IN=)>
  <HiddenControl(assoc_term_in=) (readonly)>
  <HiddenControl(start_date_in=) (readonly)>
  <HiddenControl(end_date_in=) (readonly)>
  <HiddenControl(RSTS_IN=WR) (readonly)>

  <TextControl(CRN_IN=)>
  <HiddenControl(assoc_term_in=) (readonly)>
  <HiddenControl(start_date_in=) (readonly)>
  <HiddenControl(end_date_in=) (readonly)>
  <HiddenControl(RSTS_IN=WR) (readonly)>

如我的 sn-p 代码所示，我可以使用 id='crn_id1' 选择 1 - 10 个文本框，一直到 id=crn_id10。但是，我的问题是，当我尝试以下操作时：

add_control = br.form.find_control(name='CRN_IN', id='crn_id1')
add_control['CRN_IN'] = '34688' # this indicates a CRN to submit
response = br.submit()

我收到以下错误：

Traceback (most recent call last):
  File "./add2.py", line 37, in <module>
    add_control['CRN_IN'] = '34688'
  File "/usr/local/lib/python2.7/site-packages/mechanize/_form.py", line 1212, in __getattr__
    (self.__class__.__name__, name))
AttributeError: TextControl instance has no attribute '__setitem__'

编辑：

将.select_form() 添加到find_control 行后，出现以下错误：

Traceback (most recent call last):
  File "./add2.py", line 35, in <module>
    add_control = br.form.find_control(name='CRN_IN', id='crn_id1').select_form()
  File "/usr/local/lib/python2.7/site-packages/mechanize/_form.py", line 1212, in __getattr__
    (self.__class__.__name__, name))
AttributeError: TextControl instance has no attribute 'select_form'

标签： python forms submit mechanize

【解决方案1】：

只需添加：

add_control.value = '33587'
