golang的string字符串常用函数

str1 := "itceshi"

result := strings.Contains(str1, "cesh")

fmt.Println(result)str := []string{"a", "b", "c", "d", "e", "f"}

join := strings.Join(str, "")

fmt.Println("join：", join)str := "[email protected]"

split := strings.Split(str, "@")

fmt.Println("split：", split)str := "qqhao123"

result3 := strings.Index(str, "hao")

fmt.Println("result：", result3)str := "Aceceshi"

result4 := strings.Repeat(str, 3)

fmt.Println("result：", result4)

func Replace(s, old, new string, n int) string

在s字符串中，把old字符串替换为new字符串，n表示替换的次数，小于0表示全部替换

str := "Azzhao"

strings.Replace(str, "z", "Z", 1)// 替换第一个

strings.Replace(str, "z", "Z", -1)// 全部替换

func Trim(s string, cutset string) string

t在s字符串的头部和尾部去除cutset指定的字符串

str := " [email protected] "

trim := strings.Trim(str, " ") // 去掉两头空格

fmt.Println("trim：", trim)str := " [email protected] "

fields := strings.Fields(str)

fmt.Println("fields：", fields)
