Convert request body content to anonymous struct that i can access attributes

[Paulo Coutinho]

Hi,

I want convert the body of request to an anonymous struct or something that i can access the attributes.

My current code:

func (s *CustomerController) customerAdd(c *gin.Context) {
   decoder := json.NewDecoder(c.Request.Body)
   var t interface{}
   err := decoder.Decode(&t)
   if err != nil {
      log.Println("PAM! > ")
      log.Println(err)
   } else {
      log.Println("JSON CONV: ")
      log.Println(t)
   }
}

But it is the object converted:

JSON CONV: 

map[field3:map[field4:field 4 value] field5:1 field1:fiel 1 value field2:fiel áéíóú value]

Can anyone help me?

My json:

{

    "field1": "fiel 1 value",

    "field2": "fiel áéíóú value",

    "field3": {

        "field4": "field 4 value"

    },

    "field5": 1

}

I need access the data of my object (t). 

Thanks.

I get the field now, but need change the type of "t":

func (s *CustomerController) customerAdd(c *gin.Context) {
   decoder := json.NewDecoder(c.Request.Body)

   var t map[string]interface{}

   err := decoder.Decode(&t)
   if err != nil {
      log.Println("PAM! > ")
      log.Println(err)
   } else {
      log.Println("JSON CONV: ")
      log.Println(t)

      log.Println("VALUE: ")
      log.Println(t["field1"])
   }
}

This is a good way?

Acceptable, if you don't know the keys beforehand. Or define a struct for the known keys and unmarshal into that.

If the JSON is complicated, you can get the struct definition automatically using https://mholt.github.io/json-to-go/ . You can decode into that struct and access the fields.
