Go语言中字符串操作常用函数介绍

- 操作 ```go //"helloogo"中是否包含"hello" fmt.Println(strings.Contains("helloogo", "hello")) fmt.Println(strings.Contains("helloogo", "goe")) //Join组合 s := []string{"abc", "hello", "mike", "go"} buf := strings.Join(s, "_") fmt.Println("buf = ", buf) //Index 查找子串所在位置 fmt.Println(strings.Index("abcdhello", "hello")) fmt.Println(strings.Index("abcdhello", "go")) //Repeat 重复打印 buf = strings.Repeat("go", 3) fmt.Println("buf = ", buf) //Split 以指定的分隔符对字符串进行拆分 buf = "hello&abc&go&mike&you" s2 := strings.Split(buf, "&") fmt.Println("s2 = ", s2) //Trim 去掉两头的字符 buf = strings.Trim(" are you ok ", " ") fmt.Println("buf = ", buf) //Fields 去掉空格，把元素放入切片中 s3 := strings.Fields(" are you ok? ") for i, data := range s3 { fmt.Println(i, ", ", data) } ``` - 输出 ``` true false buf = abc_hello_mike_go 4 -1 buf = gogogo s2 = [hello abc go mike you] buf = are you ok 0 , are 1 , you 2 , ok? ```
