英文:
scanning spaces from stdin in Go
问题
我正在尝试使用标准的"fmt"包从标准输入中扫描一些命令。
然而，似乎scanf在第一个空格后停止。你有什么办法可以解决这个问题吗？
var in string
for err != nil {
_, err = fmt.Scanf("%s", &in)
}
fmt.Println(in)

I'm trying to scan some commands from stdin using the standard "fmt" package
However it seems that scanf stops after the first space. Any idea how I can fix it?
var in stringfor err != nil {_, err = fmt.Scanf("%s", &in)}fmt.Println(in)

我发现我需要的东西在bufio.Scan包中。
scanner := bufio.NewScanner(os.Stdin)for scanner.Scan() {return scanner.Text()}if err := scanner.Err(); err != nil {fmt.Fprintln(os.Stderr, "读取标准输入时出错:", err)}
英文:
I found that what I needed was in the bufio.Scan package
scanner := bufio.NewScanner(os.Stdin)for scanner.Scan() {return scanner.Text()}if err := scanner.Err(); err != nil {fmt.Fprintln(os.Stderr, "reading standard input:", err)}
