Func getmsg () (msg string) {  Reader: = Bufio. Newreader (OS. Stdin)   If err! = Nil {    FMT. Println (Err. Error ())  }  return}

Briefly summarize:

Reader is a pointer because of BUFIO. The interface of the Newreader () constructor is the func newreader (rd IO. Reader) *reader

(*reader, as can be seen from here)

1. Reader: = Bufio. Newreader (OS. Stdin), a reader was created

2.msg, err: = Reader. ReadString (' \ n ')

ReadString (Delim byte) is a method.

Reads to the Delim character and ends, and returns Error=nil to err.

So msg gets the OS. stdin the input string plus (' \ n ') wrapping. ( remember )

Finally, the MSG is returned, corresponding to the function name, and the msg+ (' \ n ') information is obtained.
