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
