Silence user input in Scan function
问题
如何在终端中隐藏用户输入（密码字段），类似于bash中的read -s p "password" password命令中的-s选项？
package main
import (
"fmt"
"golang.org/x/term"
)
func main() {
fmt.Println("password: ")
password, _ := term.ReadPassword(0)
fmt.Println("You entered:", string(password))
}
你可以使用golang.org/x/term包中的ReadPassword函数来隐藏用户输入。
英文:
How do I hide user input (password field) in terminal similar to the -s command in read -s p "password " password in bash. ?
var password string
fmt.Println("password: ")
fmt.Scan(&password)

最好的方法是使用终端包中的ReadPassword()函数。或者你也可以查看这个问题，了解更多实现方式。
代码示例：
package main
import "golang.org/x/crypto/ssh/terminal"
import "fmt"
func main() {
fmt.Println("输入密码：")
password, err := terminal.ReadPassword(0)
if err == nil {
fmt.Println("输入的密码：" + string(password))
}
}
英文:
The best way would be to use ReadPassword() from the terminal package. Else you can also look in this question for more ways to do so.
Code example:
package main
import "golang.org/x/crypto/ssh/terminal"
import "fmt"
func main() {
fmt.Println("Enter password: ")
password, err := terminal.ReadPassword(0)
if err == nil {
fmt.Println("Password typed: " + string(password))
}
}

我对go语言不太了解，所以不确定你是否可以调用其他程序。如果可以的话，只需调用stty -echo来隐藏输入，然后调用stty echo来再次显示。
否则，你可以尝试以下代码：
fmt.Println("password: ")
fmt.Println("3[8m") // 隐藏输入
fmt.Scan(&password)
fmt.Println("3[28m") // 显示输入
英文:
I have no idea about go, so I'm not sure if you can call other programs. If so, just call stty -echo to hide input and stty echo to show it again.
Otherwise you could try the following:
fmt.Println("password: ")
fmt.Println("3[8m") // Hide input
fmt.Scan(&password)
fmt.Println("3[28m") // Show input

为了支持Windows，如这里所提到的，请使用以下代码：
import "syscall"
import "golang.org/x/crypto/ssh/terminal"
passwd, err := terminal.ReadPassword(int(syscall.Stdin))
英文:
To support windows, as mentioned here, please use:
import "syscall"
import "golang.org/x/crypto/ssh/terminal"
passwd, err := terminal.ReadPassword(int(syscall.Stdin))

我尝试了几种不同的方法，并发现了一些问题（例如，如果程序正在等待密码，Ctrl+C无法中断程序）。
这是我最终让它正常工作的方法-在OSX中完美运行。我还没有在其他环境中尝试过：
import (
"log"
"code.google.com/p/go.crypto/ssh/terminal"
"github.com/seehuhn/password"
)
func StringPrompt() (password string, err error) {
state, err := terminal.MakeRaw(0)
if err != nil {
log.Fatal(err)
}
defer terminal.Restore(0, state)
term := terminal.NewTerminal(os.Stdout, "")
password, err = term.ReadLine()
if err != nil {
log.Fatal(err)
}
return
}
英文:
I tried a couple of different methods for this and found issues (e.g. Ctrl+C not breaking out of the program if it's waiting for a password).
This is how I got it working in the end - this works perfectly in OSX. Haven't tried in other environments:
import (
"log"
"code.google.com/p/go.crypto/ssh/terminal"
"github.com/seehuhn/password"
)
func StringPrompt() (password string, err error) {
state, err := terminal.MakeRaw(0)
if err != nil {
log.Fatal(err)
}
defer terminal.Restore(0, state)
term := terminal.NewTerminal(os.Stdout, "")
password, err = term.ReadLine()
if err != nil {
log.Fatal(err)
}
return
}
