golang 如何获取文件夹下面的文件列表

package main 
import (
    "fmt"
    "io/ioutil"
)
 
func main() {
    files, _ := ioutil.ReadDir("./")
    for _, f := range files {
            fmt.Println(f.Name())
    }
}

package main  
import (
    "fmt"
    "path/filepath"
)
 
func main() {
    files, _ := filepath.Glob("*")
    fmt.Println(files) // contains a list of all files in the current directory
}

func DirSize(path string) (int64, error) {
 var size int64
 err := filepath.Walk(path, func(_ string, info os.FileInfo, err error) error {
  if !info.IsDir() {
   size += info.Size()
  }
  return err
 })
 return size, err
}
