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,自建方法“==”的速度要比Compare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
