尝试在沙盒中使用信用卡付款时出现 PayPal 错误
PayPal error while trying to pay with credit card in sandbox
在测试使用信用卡直接支付时，我总是得到以下错误："You cannot use an e-mail address or card number that belongs to an existing PayPal account. If you have a PayPal account, please log in. If you don't, please change the e-mail address or card number and try again"。
我用于测试的信用卡号码来自 http://www.paypalobjects.com/en_US/vhelp/paypalmanager_help/credit_card_numbers.htm but I also tried those produced by http://www.getcreditcardnumbers.com/.
最后，我通过在连接到我的站点之前清理浏览器缓存和 cookie 找到了解决方案。
这很奇怪，但似乎在浏览器中有一个 PayPal cookie（在以前的 PayPal 交易期间创建）导致它也在客人付款尝试期间使用。
