Go file path operation

The files in the test directory are as follows ：

• main.go
• 1.txt
• ./a/b/2.txt

Get all files in the specified folder ( Not a recursive )

package main

import (
	"fmt"
	"io/ioutil"
)

func main() {
    
	baseDir := "./"
	fileInfos, _ := ioutil.ReadDir(baseDir)

	for _, f := range fileInfos {
    
		if f.IsDir(){
    
			continue
		}
		fmt.Println(f.Name())
	}
}

Output ：

PS E:\Go Project\pathtest> go run main.go
1.txt
main.go

Get all files in the specified folder （ recursive ）

package main

import (
	"fmt"
	"io/ioutil"
	"path/filepath"
)

func main() {
    
	baseDir := "./"

	files := ReadFiles(baseDir)
	for _, file := range files {
    
		fmt.Println(file)
	}
}

func ReadFiles(dir string) []string {
    
	result := make([]string, 0)
	fileInfos, _ := ioutil.ReadDir(dir)

	for _, f := range fileInfos {
    
		if f.IsDir() {
    
			result = append(result, ReadFiles(filepath.Join(dir, f.Name()))...)
		} else {
    
			result = append(result, filepath.Join(dir, f.Name()))
		}
	}
	return result
}

Output ：

PS E:\Go Project\pathtest> go run main.go
1.txt
a\b\2.txt
main.go

Path splicing

route ：./a/b/2.txt Realize splicing ：

func main() {
    
	baseDir := "./"
	aDir := "a"
	bDir := "b"
	file := "2.txt"

	absFilePath := filepath.Join(baseDir, aDir, bDir, file)
	fmt.Println(absFilePath)
}

Output ：

PS E:\Go Project\pathtest> go run main.go
a\b\2.txt
