终端读写
操作终端相关文件句柄常量
os.Stdin：标准输入
os.Stdout：标准输出
os.Stderr：标准错误输出终端读写示例：

package mainimport ( "fmt")var ( firstName, lastName, s string i int f float32 input = "56.12 / 5212 / Go" format = "%f / %d / %s")func main() { fmt.Println("Please enter your full name: ") fmt.Scanln(&firstName, &lastName) // fmt.Scanf("%s %s", &firstName, &lastName) fmt.Printf("Hi %s %s!\n", firstName, lastName) // Hi Chris Naegels fmt.Sscanf(input, format, &f, &i, &s) fmt.Println("From the string we read: ", f, i, s)}带缓冲区的读写（磁盘io比较慢，所以将数据先存入缓存）：

package mainimport ( "bufio" "fmt" "os")var inputReader *bufio.Readervar input stringvar err errorfunc main() { inputReader = bufio.NewReader(os.Stdin) fmt.Println("Please enter some input: ") input, err = inputReader.ReadString('\n') if err == nil { fmt.Printf("The input was: %s\n", input) }}

package mainimport ( "bufio" "os" "fmt")func main() { reader := bufio.NewReader(os.Stdin) //以换行为分割，注意单引号'' str, err := reader.ReadString('\n') if err != nil { fmt.Println(err) return } fmt.Println("输入的是：", str)}

输入输出：
我日啊
输入的是： 我日啊
