package main

import (

    "fmt"

    "path"

    "strings"

)

func main() {

    fullFilename := "/Users/itfanr/Documents/test.txt"

    fmt.Println("fullFilename =", fullFilename)

    var filenameWithSuffix string

    filenameWithSuffix = path.Base(fullFilename) //获取文件名带后缀

    fmt.Println("filenameWithSuffix =", filenameWithSuffix)

    var fileSuffix string

    fileSuffix = path.Ext(filenameWithSuffix) //获取文件后缀

    fmt.Println("fileSuffix =", fileSuffix)

    var filenameOnly string

    filenameOnly = strings.TrimSuffix(filenameWithSuffix, fileSuffix)//获取文件名

    fmt.Println("filenameOnly =", filenameOnly)

}
