操作 表达式 返回值 判断字符串中是否包含某个子串 Contains("hello","he") true;false 将字符串切片中的元素组合成一个字符串 strings.Join([]string{"hello","world","!"}," ") hello world ! 查找子串在字符串中的位置 strings.Index("hello","ll ") 下标值;-1(子串不存在) 以指定字符拆分字符串 strings.Split("hello,world,everyone",",") [hello world everyone] 剪裁字符串两头的指定字符 strings.Trim("!!Hello world!!","!") Hello world 以空格区分，将字符串转换成字符串切片 strings.Fields(" Hello world ") [Hello world] 
package main

import (
    "fmt"
    "strings"
)

func main() {
    fmt.Println(strings.Contains("hello","he"))
    fmt.Println(strings.Join([]string{"hello","world","!"}," "))
    fmt.Println(strings.Index("hello","l1l"))
    fmt.Println(strings.Split("hello,world,everyone",","))
    fmt.Println(strings.Trim("!!Hello world!!","!"))
    fmt.Println(strings.Fields("  Hello world   "))
}

运行结果：

true
hello world !
-1
[hello world everyone]
Hello world
[Hello world]
