golang字符串常用操作

 

获取字符串的长度

package main
 

import (
    "fmt"
)
 

var name string = "helloworld"
 

func main() {
    fmt.Println(len(name ))
}
 

 

字符串拼接

func main() {
    info := name + fmt.Sprintf(" %d", age)
    fmt.Println(info)
}

 

 字符串切割

  

 

var name string = "helloworld"

func main() {

  info := strings.Split(name, "ll")

    fmt.Println(info)

}

 

判断是否包含

var name string = "helloworld"

func main() {
    if strings.Contains(name, "h") {
        fmt.Println("Contains")
    }
}

 

判断前缀后缀

var name string = "helloworld"

func main() {
    fmt.Println(strings.HasPrefix(name, "h"))
    fmt.Println(strings.HasSuffix(name, "d"))
}

判断字符出现的索引位置

var name string = "helloworld"

func main() {
    fmt.Println(strings.Index(name, "l"))
    fmt.Println(strings.LastIndex(name, "l"))
}

 

切片元素拼接字符串

var name string = "helloworld"

func main() {
    nameList := make([]string, 0)
    nameList = append(nameList, name)
    nameList = append(nameList, name)
    fmt.Println(strings.Join(nameList, ","))
}

字符串转义符

Go 语言的字符串常见转义符包含回车、换行、单双引号、制表符等，如下表所示。

\r          回车符

\n          换行

\t          制表符

\\          反斜杠
