go语言扫描目录

// 扫描当前目录下文件，不递归扫描
func scanDir(dirName string) []string {

files, err := ioutil.ReadDir(dirName)

if err != nil {
log.Println(err)
}
var fileList []string
for _, file := range files {
fileList = append(fileList, dirName+string(os.PathSeparator)+file.Name())
}
return fileList
}

// 递归扫描目录
