go语言使用scp的方法实例分析

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。
