Question

我有一个HTML表单，我想用WWW::Mechanize模块处理。我似乎无法发布包含美元符号$的输入值。我收到此运行时错误消息：

Can't call method "value" on an undefined value at script.pl line 599

我的脚本看起来像这样

my $agent = WWW::Mechanize->new( autocheck => 1, ssl_opts => { verify_hostname => 0 }, );
my $formfiller = WWW::Mechanize::FormFiller->new();

$agent->env_proxy();
$agent->get('https://site.com/form.php');
$agent->form_number(1) if $agent->forms and scalar @{$agent->forms};
$agent->form_number(1);

{
  local $^W;
  $agent->current_form->value('page_contentleft_0$form_D69D9E5239FC412ABB92A81D73F690AD$field_F40A1785D7B3490CBD5E72EDBE6B966D', 'John Doe');
}; #// First NAme
{
  local $^W;
  $agent->current_form->value('page_contentleft_0$form_D69D9E5239FC412ABB92A81D73F690AD$field_E3316C46A4404C73ACBAE107DF6206D2', 'Bridgeport');
}; #// City
{
  local $^W;
  $agent->current_form->value('page_contentleft_0$form_D69D9E5239FC412ABB92A81D73F690AD$field_E5747EB507E74DC1937557F9285CB57C', 'CT');
}; #// state
{
  local $^W;
  $agent->current_form->value('page_contentleft_0$form_D69D9E5239FC412ABB92A81D73F690AD$field_A612569BE44C4BA3AD0AB3FBF8FB0553', '06604');
}; #// Zipcode

$agent->submit(Submit);

据我所知，问题是从参数到value方法，例如

page_contentleft_0$form_D69D9E5239FC412ABB92A81D73F690AD$field_A612569BE44C4BA3AD0AB3FBF8FB0553

如何让Perl通过$，或以其他方式解决？

你确定有吗？

$agent->submit(Submit);

请尝试使用此代码：

           $agent->get('https://site.com/form.php');

           $agent->submit_form(
     with_fields => {
'page_contentleft_0$form_D69D9E5239FC412ABB92A81D73F690AD$field_F40A1785D7B3490CBD5E72EDBE6B966D' => 'John Doe', 
'page_contentleft_0$form_D69D9E5239FC412ABB92A81D73F690AD$field_E3316C46A4404C73ACBAE107DF6206D2' => 'Bridgeport',     
'page_contentleft_0$form_D69D9E5239FC412ABB92A81D73F690AD$field_E5747EB507E74DC1937557F9285CB57C' => 'CT',     
'page_contentleft_0$form_D69D9E5239FC412ABB92A81D73F690AD$field_A612569BE44C4BA3AD0AB3FBF8FB0553' => '06604'},
           button => "Submit",);

无法使用WWW :: Mechanize提供复杂的表单值
