如何通过使用Groovy或Java的IPv6访问网站
我试图通过IPv6访问网页，但总是得到一个“NoRouteToHostException：没有路由到主机”。 我尝试了以下内容：
println 'http://[2001:4810:0:0:0:0:0:110]:80/'.toURL().text
结果是：
Caught: java.net.NoRouteToHostException: No route to host
java.net.NoRouteToHostException: No route to host
at IPv6Tester.run(IPv6Tester.groovy:116)
然后我试着：
def authSite = new groovyx.net.http.HTTPBuilder( 'http://[2620:109:c00d:100:0:0:c765:a381]:80/' )
println authSite.get( path: '/search/users' ) { resp, headers ->
println "response status: ${resp.statusLine}"
}
导致：

Jsoup也一样：
def profilePage = Jsoup.connect('http://[2001:4810:0:0:0:0:0:110]:80/').userAgent(USER_AGENT).timeout(TIMEOUT).get()

顺便说一句。 如果我从IPv6打开一个Socket到远程IPv6，我可以读取根页面（但不是服务器上的特定路径）。
我假设我必须使用绑定本地IPv6地址的Socket来访问远程IPv6地址，但我找不到这样做的方法。 任何帮助，将不胜感激！
您收到的错误“没有路由到主机”是正确的。
您尝试访问的IP地址都不可路由或可从全球互联网访问。
要解决该问题，请连接到有效的实时IPv6地址。
