java - Heroku Java 应用程序是否能够访问外部站点上的资源？

Question

我有一个 Java 应用程序，可以解析外部站点上的一些 XML。 据我所知，对任何外部站点的访问似乎都会受到防火墙的限制。

Firewalls are utilized to restrict access to systems from external networks and between systems internally. By default all access is denied and only explicitly allowed ports and protocols are allowed based on business need. Each system is assigned to a firewall security group based on the system’s function. Security groups restrict access to only the ports and protocols required for a system’s specific function to mitigate risk.

有谁知道是否或如何克服这个限制？这些“安全组”就是答案吗？

Answer 1

从您的应用程序访问外部站点上的数据完全没有问题。该安全策略是关于如何保护 Heroku 自己的内部基础设施的安全。这不是对您的应用的限制。
