比如 https://q.cnblogs.com/ 这个 url ,前面的 https:// 怎么命名?用英文句子表达就是 "The scheme is followed by a colon and two forward slashes." (句子来源)
https://q.cnblogs.com/
https://
参见https://en.wikipedia.org/wiki/Uniform_Resource_Identifier#Examples
schema 就是正解
protocol :// hostname[:port] / path / [;parameters][?query]#fragment
