golang 字符串相等比较

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"))

输出结果

true
false
-1
0
true

• 内建方法"==”，区分大小写，最简单的方法
• Compare函数，区分大小写，比内建方法“==”的速度要快

/ 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

• 比较UTF-8编码条件下是否相等，不区分大小写

  // EqualFold reports whether s and t, interpreted as UTF-8 strings,
  // are equal under Unicode case-folding.
  func EqualFold(s, t string) bool
