Paypal自适应支付迷你浏览器

Question

我正在尝试使用 PHP 中使用 Codeigniter 框架的迷你浏览器选项为我的产品使用 Paypal 自适应支付。当我点击支付按钮时，迷你浏览器打开得很好，但是当我点击登录按钮时，新选项卡打开，但我想在现有的迷你浏览器中打开这个登录。

PayPal 的安全要求会在某些情况下强制执行新的 window（并且 javascript 强制执行此操作）。通常，当用户输入登录凭据时，他们需要这样做，这可能是您在问题中使用 "login" 与 "payment" 按钮所指的？

这样做是为了最大限度地降低通过跨站点脚本攻击窃取凭据的风险，并确保用户看到 "chrome"（例如安全连接符号和 PayPal URL）并可以验证 window 在输入凭据时安全地连接到 PayPal（出于反网络钓鱼的原因）。

一些较新的 PayPal 产品放宽了这些要求，但我相当确定 Adaptive 坚定地采用了这种模式。
