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：

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。
