在Go中列出目录 [英] List directory in Go

问题描述

我找到了 filepath.Walk ，但它会自动进入子目录，其中I不想要。我所有的其他搜索都没有改变任何事情。

我确定这个功能存在，但它真的很难找到。如果有人知道我应该看哪里，请告诉我。谢谢。

/＃ReadDirrel =noreferrer> ReadDir 函数的 io / ioutil 包中。根据文档：

ReadDir读取由dirname命名的目录并返回一个已排序的目录条目列表。

结果切片包含 os.FileInfo 类型，它们提供列出的方法这里。下面是一个基本的例子，列出当前目录中所有内容的名称（包含文件夹但未特别标记 - 您可以通过使用 IsDir（）



  package main 
 
 import（
fmt
io / ioutil
log
）
 
 func main（）{
 files，err：= ioutil.ReadDir（./） 
如果err！= nil {
 log.Fatal（err）
} 
 
 for _，f：=范围文件{
 fmt.Println（ f.Name（））
} 
} 
  




I've been trying to figure out how to simply list the files and folders in a single directory in Go.

I've found filepath.Walk, but it goes into sub-directories automatically, which I don't want. All of my other searches haven't turned anything better up.

I'm sure that this functionality exists, but it's been really hard to find. Let me know if anyone knows where I should look. Thanks.

解决方案

You can try using the ReadDir function in the io/ioutil package. Per the docs:

ReadDir reads the directory named by dirname and returns a list of sorted directory entries.

The resulting slice contains os.FileInfo types, which provide the methods listed here. Here is a basic example that lists the name of everything in the current directory (folders are included but not specially marked - you can check if an item is a folder by using the IsDir() method):

package main

import (
    "fmt"
    "io/ioutil"
     "log"
)

func main() {
    files, err := ioutil.ReadDir("./")
    if err != nil {
        log.Fatal(err)
    }

    for _, f := range files {
            fmt.Println(f.Name())
    }
}
