GO語言: 讀取設定檔的方式toml

最近go語言項目中用到讀取設定檔，如下：
使用這個"github.com/BurntSushi/toml"
設定檔如下：conf.toml

# idID = 1# nameName = "name1"# weightWeight = 1.7# booksBooks = ["a", "b", "c"]Sex = true#friend Friend都可以[friend]Age = 32Name = "xio"

代碼如下 readConf.go：

package confimport ("fmt""github.com/BurntSushi/toml""io/ioutil""os")// persontype Person struct {ID     uint32Sex    boolName   stringWeight float32Friend *FriendsBooks  []string}// friendstype Friends struct {Age  intName string}func ReadConf(fname string) (p *Person, err error) {var (fp       *os.Filefcontent []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}

測試代碼如下 readConf_test.go：

package confimport "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)}

輸出結果為：

[ `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

細節點：

1 結構體的成員首字母大寫
2 設定檔的配置項須與結構體成員名一樣
3 支援bool， int， float ， 字串，字串數組...等，也可以包含其他結構體 如[Friend]
