There's no standard way of obtaining that information. 没有获取信息的标准方法。

You can try to mimic Mozilla in their autoconfiguration , or follow RFC 6186 which provides a useful and standard-compliant way of what you're looking for. 您可以尝试模仿Mozilla的自动配置，也可以遵循RFC 6186 ， RFC 6186提供了一种有用且符合标准的查找方式。 However, these mechanisms are voluntary, their adoption varies and you cannot rely on them at all. 但是，这些机制是自愿的，采用的方式各不相同，您完全不能依赖它们。
