我需要获取这种情况下的 host，遇到这个问题。网上搜了好久没找到合适的资料，哪位大大遇到过帮看看，在此感谢
因为 "http://www.baidu.com/xEA\xE6" 包含了非法的 utf-8 字符
str = "http://www.baidu.com/xEA\xE6"
str.valid_encoding? # => false
解决办法，先把 str 中得非法 utf-8 字符替换掉，比如替换成 ?
for i in (0...str.size)
unless str[i].valid_encoding?
str[i] = "?"
end
end
str.valid_encoding? # => true
enjoy!
