go语言使用scp的方法实例分析

来源:转载


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:

代码如下:package main
import (
    "code.google.com/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。
