golang interface to struct and string to struct

1. interface to struct

例如:

type Token struct {
   SuiteToken      string `json:"suite_access_token"`
   ExpiresIn int64  `json:"expires_in"`
}

var token = &{ABSXXXXXXX 7200}

要想将token转换成为Token类型的结构体

         var t Token 

         t = token.(Token)  //t 即为 Token类型结构

2. string and []byte to struct

var token Token
var t = {"suite_access_token":"rFA9KClmPsss","expires_in":7200}
json.Unmarshal(t,&token)  //token 即为Token结构

 

3. string to []byte and []byte to string

   str2 := "hello"     

   data2 := []byte(str2)  //string to byte

 fmt.Println(data2)

data1 := string(data2) //byte to string

fmt.Println(data1)
