Go language: How to read a configuration file toml

The read configuration file is used in the recent Go Language project as follows:
Use this "github.com/burntsushi/toml"
The configuration file is as follows: CONF.TOML

# id
id = 1
# name
name = "name1"
# weight
weight = 1.7
# books
books = ["A", "B", "C"]
Se x = True

#friend friend can be
[friend] Age
= +
Name = "Xio"

The code is as follows Readconf.go:

Package conf

Import (
	"FMT",
	"github.com/burntsushi/toml" "
	io/ioutil" "
	os"
)

/person
type person struct {
	ID     uint32
	Sex    bool
	Name   string
	Weight float32
	Friend *friends
	Books  []string
}

//Friends
type Friends struct {
	age  int
	Name string
}

func readconf (fname String) (p *person, err error) {
	var (
		fp       *os. File
		fcontent []byte
	]
	p = new (person)//&person{}
	if fp, err = OS. Open (fname); Err! = Nil {
		FMT. PRINTLN ("Open error", err)
		return
	}

	if fcontent, err = Ioutil. ReadAll (FP); Err! = Nil {
		FMT. PRINTLN ("ReadAll error", err)
		return
	}

	If Err = toml. Unmarshal (Fcontent, p); Err! = Nil {
		FMT. Println ("toml. Unmarshal error ", err)
		return
	}
	return
}

The test code is as follows Readconf_test.go:

Package conf

Import "testing"

func testreadconf (t *testing. T) {
	p, err: = Readconf ("./conf.toml")
	if err! = Nil {
		T.logf ("%v", Err)
	}

	t.logf ("Person%v", p) 
  
   t.logf ("Person.friend%v", P.friend)
}
  

The output is:

[' Go test-v ' | done:2.6748515s]
  = = = RUN   testreadconf
  ---pass:testreadconf (0.00s)
    Readconf_test.go:11:person &{1 true name1 1.7 0x1218c570 [a b c]}
    readconf_test.go:12:person.friend &{32 Xio}
  PASS
  OK    goprogram/conf  0.458s

Detail point:

1 member of struct First capital letter
2 configuration items for configuration files must be the same as struct member names
3 supports bool, int, float, string, string array ... can also contain other structures such as [Friend]
