为什么我的WWW :: Mechanize不提交PayPal表单工作？

Question

我尝试过的任何内容都无法正确提交我的代码.其他人可以解决这个问题吗？

#!/usr/bin/perl

use WWW::Mechanize;


my $user = 'cowsaremyfriends@gmail.com';
my $pass  = 'hackswipe';
# Test account; don't worry


my $browser = WWW::Mechanize->new();
$browser->get("https://www.paypal.com/");
$browser->form_with_fields("login_email", "login_password");
$browser->field("login_email", $user);
$browser->field("login_password", $pass);
$browser->submit_form();
$browser->get("https://www.paypal.com/us/cgi-bin/webscr?cmd=_profile-api-add-direct-access");
##### Help here ---> Trying to submit form with default option selected #####
my $html = $browser->content;

print $html;

它适用于我,但是当涉及调试Web scraper等时,您应该观察HTTP事务.这很容易添加,因为WWW :: Mechanize是一个LWP :: UserAgent子类:

use WWW::Mechanize;

my $browser = WWW::Mechanize->new();

# See LWP::Debug
$browser->add_handler("request_send",  sub { shift->dump; return });
$browser->add_handler("response_done", sub { shift->dump; return });

现在,您可以看到您发送的内容以及PayPal发回的内容.

通常你也可以使用各种HTTP嗅探工具,但那些只适用于你用明文发送的东西,所以你在这里运气不好.

但是,在这种情况下,PayPal会对您有所帮助.他们知道你正在使用脚本.我得到的部分输出是:

<h2>Request API Credentials</h2>
</div>
<div id="messageBox"></div>
<div id="main"><div class="layout1"><form action="https://www.paypal.com/us/cgi-bin/webscr?dispatch=5885d80a13c0db1f8e263663d3faee8dc18bca4c6f47e633b393e284a5f8a8f8" class="">

<ul>
<li>An API username</li>
<li>An API password</li>
<li>Either an API signature or an API SSL client-side certificate</li>
</ul>
<p>If you’re using a shopping cart or solution provider, ask whether you need an API signature or a certificate.</p>

如果您想通过程序与PayPal进行交互,则需要注册开发人员访问权限.
