How to feed a password to SSH?
问题
我需要使用基于密码的身份验证的scp来从服务器下载文件。如何使用Go实现这个功能？我尝试了以下代码，但它没有传递密码。
package main
import (
"os/exec"
"time"
)
func main() {
password := "password"
cmd := exec.Command("scp", "admin@192.168.1.150:file", "file")
in, err := cmd.StdinPipe()
if err != nil {
panic(err)
}
defer in.Close()
out, err := cmd.StdoutPipe()
if err != nil {
panic(err)
}
defer out.Close()
if err = cmd.Run(); err != nil {
panic(err)
}
go func() {
time.Sleep(10 * time.Second)
_, err = in.Write([]byte(password + "\n"))
if err != nil {
panic(err)
}
}()
}
编辑：我最终使用了gexpect（github.com/ThomasRooney/gexpect）库。
package main
import (
"github.com/ThomasRooney/gexpect"
"log"
)
func main() {
child, err := gexpect.Spawn("scp admin@192.168.1.150:file file")
if err != nil {
log.Fatalln(err)
}
child.Expect("password:")
child.SendLine("password")
child.Interact()
child.Close()
}
希望对你有帮助！

I need to use password authenticated scp to download a file from a server. How do I do so using Go? Tried the following code, but it doesn't pass in the password.
package main
import (
"os/exec"
"time"
)
func main() {
password := "password"
cmd := exec.Command("scp", "admin@192.168.1.150:file", "file")
in, err := cmd.StdinPipe()
if err != nil {
panic(err)
}
defer in.Close()
out, err := cmd.StdoutPipe()
if err != nil {
panic(err)
}
defer out.Close()
if err = cmd.Run(); err != nil {
panic(err)
}
go func() {
time.Sleep(10 * time.Second)
_, err = in.Write([]byte(password + "\n"))
if err != nil {
panic(err)
}
}()
}
Edit: I ended up using the gexpect (github.com/ThomasRooney/gexpect) library.
package main
import (
"github.com/ThomasRooney/gexpect"
"log"
)
func main() {
child, err := gexpect.Spawn("scp admin@192.168.1.150:file file")
if err != nil {
log.Fatalln(err)
}
child.Expect("password:")
child.SendLine("password")
child.Interact()
child.Close()
}

这个自问自答的问题的答案可能会有所帮助：

至少，在答案中他提到他“能够通过密码获得ssh访问权限”，这在问题中没有明确提到 - 这就是为什么你在搜索网站时可能没有找到它的原因。

at least, he mentions in the answer that he "was able to get ssh access working with a password", which is not mentioned explicitly in the question - that's why you probably didn't find it while searching the site?
