我们通过NewReader(string)构建一个Reader对象,随后就可以通过Read()读取Reader的内容,以下是其使用: packagemain import( "fmt" "strings" ) funcmain(){ s :="Today is monday, what a great start!" sr := strings.NewReader(s) // read

Let’s now expand ourTestHumanDate()function to cover some additional test cases. Specifically, we’re going to update it to also check that: If the input tohumanDate()is thezero time, then it returns the empty string"". The output from thehumanDate()function always uses the UTC time ...
