go 전체 파일 내용을string 변수로 읽기(How can I read a whole file into a string variable)
Use  ioutil.ReadFile :
func ReadFile(filename string) ([]byte, error)

ReadFile reads the file named by filename and returns the contents. A successful call returns err == nil, not err == EOF. Because ReadFile reads the whole file, it does not treat an EOF from Read as an error to be reported.
You will get a  []byte  instead of a  string . It can be converted if really necessary:
s := string(buf)
