golang 遍历目录下的所有文件

package main
 
import (
	"fmt"
	"io/ioutil"
	"os"
)
 
var listFilePrefix string = "  "
func main() {
 
	srcDir := "D:\\test\\项目"
 
	pathSeparator := string(os.PathSeparator)
	level := 1
	listAllFileByName(level, pathSeparator, srcDir)
}
 
 
func listAllFileByName(level int, pathSeparator string, fileDir string)  {
	files, _ := ioutil.ReadDir(fileDir)
 
	tmpPrefix := ""
	for i := 1; i < level; i++ {
		tmpPrefix = tmpPrefix + listFilePrefix
	}
 
	for _, onefile := range files {
		if( onefile.IsDir() ){
			fmt.Printf("\033[34m %s %s \033[0m \n" , tmpPrefix, onefile.Name());
			//fmt.Println(tmpPrefix, onefile.Name(), "目录:")
			listAllFileByName(level + 1, pathSeparator, fileDir+ pathSeparator+ onefile.Name())
		}else {
			fmt.Println(tmpPrefix, onefile.Name())
		}
	}
 
}

递归遍历了目录下的所有文件和文件夹，且目录用蓝色显示
