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：
packagemain
import(
"code.google.com/p/go.crypto/ssh"
"crypto"
"crypto/rsa"
"crypto/x509"
"encoding/pem"
"fmt"
"io"
)
constprivateKey=`contentofid_rsa`
typekeychainstruct{
key*rsa.PrivateKey
}
func(k*keychain)Key(iint)(interface{},error){
ifi!=0{
returnnil,nil
}
return&k.key.PublicKey,nil
}
func(k*keychain)Sign(iint,randio.Reader,data[]byte)(sig[]byte,errerror){
hashFunc:=crypto.SHA1
h:=hashFunc.New()
h.Write(data)
digest:=h.Sum(nil)
returnrsa.SignPKCS1v15(rand,k.key,hashFunc,digest)
}
funcmain(){
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)
iferr!=nil{
panic("Failedtodial:"+err.Error())
}
session,err:=client.NewSession()
iferr!=nil{
panic("Failedtocreatesession:"+err.Error())
}
defersession.Close()
gofunc(){
w,_:=session.StdinPipe()
deferw.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
}()
iferr:=session.Run("/usr/bin/scp-qrt./");err!=nil{
panic("Failedtorun:"+err.Error())
}
}
希望本文所述对大家的Go语言程序设计有所帮助。
