我在安全套接字层下方有一个使用信任管理器创建隧道的东西,但我不明白允许所有主机名称的影响。谁能解释一下?
有人可以建议我需要在代码中进行哪些更改吗?

答案 0 :(得分:1)
使用AllowAllHostnameVerifier()或 SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER基本上关闭 使用SSL连接时的主机名验证。这是等效的 信任所有证书。
因此您需要更改主机名验证程序:
选项包括:
BrowserCompatHostnameVerifier
主机名必须与第一个CN或任何一个匹配 主题低价竞标。通配符可以出现在CN和任何一个中 标的ALTS。
BROWSER_COMPATIBLE和STRICT之间的唯一区别是a 带有BROWSER_COMPATIBLE的通配符(例如* .foo.com“)匹配所有 子域名,包括“a.b.foo.com。
StrictHostnameVerifier
主机名必须与第一个匹配 CN或任何主题。通配符可以出现在CN中,和 在任何主题中。与IE6的一个分歧就是我们如何 只检查第一个CN。 IE6允许与任何CN进行匹配 当下。我们决定只遵循Sun Java 1.4的脚步 检查第一个CN。 (如果你需要检查所有的CN,请随意 编写自己的实现!)。
诸如“* .foo.com”之类的通配符仅匹配相同的子域 等级,例如“a.foo.com”。它与更深的子域不匹配 例如“a.b.foo.com”。
如果要实现其中一种验证不存在的验证,则需要创建自己的主机名验证程序。
