Examples

List share names

package main

import (
	"fmt"
	"net"

	"github.com/hirochachacha/go-smb2"
)

func main() {
	conn, err := net.Dial("tcp", "SERVERNAME:445")
	if err != nil {
		panic(err)
	}
	defer conn.Close()

	d := &smb2.Dialer{
		Initiator: &smb2.NTLMInitiator{
			User:     "USERNAME",
			Password: "PASSWORD",
		},
	}

	s, err := d.Dial(conn)
	if err != nil {
		panic(err)
	}
	defer s.Logoff()

	names, err := s.ListSharenames()
	if err != nil {
		panic(err)
	}

	for _, name := range names {
		fmt.Println(name)
	}
}

File manipulation

package main

import (
	"io"
	"io/ioutil"
	"net"

	"github.com/hirochachacha/go-smb2"
)

func main() {
	conn, err := net.Dial("tcp", "SERVERNAME:445")
	if err != nil {
		panic(err)
	}
	defer conn.Close()

	d := &smb2.Dialer{
		Initiator: &smb2.NTLMInitiator{
			User:     "USERNAME",
			Password: "PASSWORD",
		},
	}

	s, err := d.Dial(conn)
	if err != nil {
		panic(err)
	}
	defer s.Logoff()

	fs, err := s.Mount("SHARENAME")
	if err != nil {
		panic(err)
	}
	defer fs.Umount()

	f, err := fs.Create("hello.txt")
	if err != nil {
		panic(err)
	}
	defer fs.Remove("hello.txt")
	defer f.Close()

	_, err = f.Write([]byte("Hello world!"))
	if err != nil {
		panic(err)
	}

	_, err = f.Seek(0, io.SeekStart)
	if err != nil {
		panic(err)
	}

	bs, err := ioutil.ReadAll(f)
	if err != nil {
		panic(err)
	}

	fmt.Println(string(bs))
}

Check error types

package main

import (
	"context"
	"fmt"
	"net"
	"os"

	"github.com/hirochachacha/go-smb2"
)

func main() {
	conn, err := net.Dial("tcp", "SERVERNAME:445")
	if err != nil {
		panic(err)
	}
	defer conn.Close()

	d := &smb2.Dialer{
		Initiator: &smb2.NTLMInitiator{
			User:     "USERNAME",
			Password: "PASSWORD",
		},
	}

	s, err := d.Dial(conn)
	if err != nil {
		panic(err)
	}
	defer s.Logoff()

	fs, err := s.Mount("SHARENAME")
	if err != nil {
		panic(err)
	}
	defer fs.Umount()

	_, err = fs.Open("notExist.txt")

	fmt.Println(os.IsNotExist(err)) // true
	fmt.Println(os.IsExist(err))    // false

	f, _ := fs.Open("hello.txt")
	_, err = f.WriteString("test")

	fmt.Println(os.IsPermission(err)) // true: on the read only share, false: otherwise

	ctx, cancel := context.WithTimeout(context.Background(), 0)
	defer cancel()

	_, err = fs.WithContext(ctx).Open("hello.txt")

	fmt.Println(os.IsTimeout(err)) // true
}
