go获取文件名和后缀

package main

import (
	"fmt"
	"path"
	"strings"
)

func main() {
	fullFilename := "D:/software/Typora/bin/typora.exe"
	fmt.Println("fullFilename =", fullFilename)
	//获取文件名带后缀
	filenameWithSuffix := path.Base(fullFilename)
	fmt.Println("filenameWithSuffix =", filenameWithSuffix)
	//获取文件后缀
	fileSuffix := path.Ext(filenameWithSuffix)
	fmt.Println("fileSuffix =", fileSuffix)

	//获取文件名
	filenameOnly := strings.TrimSuffix(filenameWithSuffix, fileSuffix)
	fmt.Println("filenameOnly =", filenameOnly)
}

输出结果如下

fullFilename = D:/software/Typora/bin/typora.exe
filenameWithSuffix = typora.exe
fileSuffix = .exe
filenameOnly = typora
