本文实例讲述了go语言使用scp的方法。分享给大家供大家参考。具体如下:
复制代码 代码如下:
package main
import (
??? "code.google测试数据/p/go.crypto/ssh"
??? "crypto"
??? "crypto/rsa"
??? "crypto/x509"
??? "encoding/pem"
??? "fmt"
??? "io"
)
const privateKey = `content of id_rsa`
type keychain struct {
??? key *rsa.PrivateKey
}
func (k *keychain) Key(i int) (interface{}, error) {
??? if i != 0 {
??????? return nil, nil
??? }
??? return &k.key.PublicKey, nil
}
func (k *keychain) Sign(i int, rand io.Reader, data []byte) (sig []byte, err error) {
??? hashFunc := crypto.SHA1
??? h := hashFunc.New()
??? h.Write(data)
??? digest := h.Sum(nil)
??? return rsa.SignPKCS1v15(rand, k.key, hashFunc, digest)
}
func main() {
??? block, _ := pem.Decode([]byte(privateKey))
??? rsakey, _ := x509.ParsePKCS1PrivateKey(block.Bytes)
??? clientKey := &keychain{rsakey}
??? clientConfig := &ssh.ClientConfig{
??????? User: "wuhao",
??????? Auth: []ssh.ClientAuth{
??????????? ssh.ClientAuthKeyring(clientKey),
??????? },
??? }
??? client, err := ssh.Dial("tcp", "127.0.0.1:22", clientConfig)
??? if err != nil {
??????? panic("Failed to dial: " + err.Error())
??? }
??? session, err := client.NewSession()
??? if err != nil {
??????? panic("Failed to create session: " + err.Error())
??? }
??? defer session.Close()
??? go func() {
??????? w, _ := session.StdinPipe()
??????? defer w.Close()
??????? content := "123456789\n"
??????? fmt.Fprintln(w, "C0644", len(content), "testfile")
??????? fmt.Fprint(w, content)
??????? fmt.Fprint(w, "\x00") // 传输以\x00结束
??? }()
??? if err := session.Run("/usr/bin/scp -qrt ./"); err != nil {
??????? panic("Failed to run: " + err.Error())
??? }
}
希望本文所述对大家的Go语言程序设计有所帮助。
