php - PayPal cURL 登录自一个月前起不再运行

Question

几个月前，一位自由编码员为我编写了一些自定义 PHP cURL，用于登录我的企业 PayPal 帐户并通过加拿大邮政打印运输标签。

大约一个月前，登录过程开始失败。请参阅下面的代码。它每次都无法通过健全性检查。有一天这段代码有效，第二天就不行了。编码器找不到问题的根源。这里的任何人都可以看到这段代码有什么问题吗？

Paypal 已更新此登录页面中的字段。替换代码:

$matches = '';
preg_match("/<input type=\"hidden\" id=\"CONTEXT_CGI_VAR\" name=\"CONTEXT\" value=\"([^\"]*)\"/siU", $response, $matches);
$form_context = $matches[1];

// echo "form_action = $form_action<br>";
// echo "form_context = $form_context<br>";

/*$query_string = "CONTEXT=$form_context&login_email=" . PAYPAL_EMAIL . "&login_password=" . PAYPAL_PASSWORD
. "&login_cmd=&login_params=&submit.x=Log%20In&operating_system=Linux&form_charset=UTF-8&browser_name=Firefox&browser_version=3";*/  

$query_string = "CONTEXT=$form_context&login_email=" . PAYPAL_EMAIL . "&login_password=" . PAYPAL_PASSWORD
. "&login_cmd=&login_params=&submit.x=Log%20In&operating_system=Windows%2NT&form_charset=UTF-8&browser_name=Firefox&browser_version=19";

与:

//changed

$matches = '';
preg_match("/<input type=\"hidden\" id=\"CONTEXT_CGI_VAR\" name=\"CONTEXT\" value=\"([^\"]*)\"/siU", $response, $matches);
$form_context = html_entity_decode($matches[1]);


$matches = '';
preg_match("/<input name=\"auth\" type=\"hidden\" value=\"([^\"]*)\"/siU", $respone, $matches);
$form_auth = urlencode($matches[1]);

//echo "form_action = $form_action<br>";
//echo "form_context = $form_context<br>";

$query_string = "CONTEXT=$form_context&login_email=" . PAYPAL_EMAIL . "&login_password=" . PAYPAL_PASSWORD
            . "&login_cmd=&login_params=&submit.x=Log%20In&operating_system=Linux&form_charset=UTF-8&browser_name=Firefox&browser_version=3&auth=$form_auth";
//end changed

您正在添加一个新的 preg_match 行和 $form_auth
