golang接受带空格的输入

I'm just starting with GO and I understand that SCANF uses spaces as a separator in GO.

fmt.Scanf("%s",&input)

I cant really find a way to accepts inputs that contain spaces as valid characters.

    When the user presses enter it signifies the end of input

    That looks like fmt.Scanln

    Scanln is similar to Scan, but stops scanning at a newline and after the final item there must be a newline or EOF.

    you can use bufio.Reader and os.Stdin:

    import(
      "bufio"
      "os"
    )
    
    in := bufio.NewReader(os.Stdin)
    
    line, err := in.ReadString('
    ')

    Similar to @chlin's answer, use bufio to capture whole lines.

    The fmt Scan methods store each space separated value into a successive arguments. Three arguments on stdin would require something like:

    package main
    
    import "fmt"
    
    func main() {
        var day, year int
        var month string
        fmt.Scanf("%d %s %d", &day, &month, &year)
        fmt.Printf("captured: %d %s %d
    ", day, month, year)
    }
    

    If you don't know the full format of what you will be reading and just want the line, use bufio:

    package main
    
    import (
      "bufio"
      "os"
    )
    
    func main(){
        scanner := bufio.NewScanner(os.Stdin)
        scanner.Scan() // use `for scanner.Scan()` to keep reading
        line := scanner.Text()
        fmt.Println("captured:",line)
    }
