Go 比较字符串是否相等
golang字符串比较的三种常见方法
fmt.Println("go"=="go")
fmt.Println("GO"=="go")
fmt.Println(strings.Compare("GO","go"))
fmt.Println(strings.Compare("go","go"))
fmt.Println(strings.EqualFold("GO","go"))
输出
true
false
-1
0
true
1,自建方法“==”,区分大小写,最简单的方法
2,Compare函数,区分大小写,比自建方法“==”的速度要快,下面是注释
/ Compare is included only for symmetry with package bytes.// It is usually clearer and always faster to use the built-in// string comparison operators ==, <, >, and so on.func Compare(a, b string) int
3,比较UTF-8编码在小写的条件下是否相等,不区分大小写,下面是注释
// EqualFold reports whether s and t, interpreted as UTF-8 strings,// are equal under Unicode case-folding.func EqualFold(s, t string) bool
