Golang中的Json Unmarshal类型模型

I have a RESTful service that returns response similar to show below:

"Basket" : {
  "Count": 1,
  "Fruits": {[
    {
      "Name":"Mango", 
      "Season":"Summer"
    },
    {
      "Name":"Fig", 
      "Season":"Winter"}
  ]}
}

I am trying to create Go lang model to unmarshal the contents. Following is the code I have tried:

type Response struct {
    Count   int
    Fruits []Fruit
}

type Fruit struct {
    Name string
    Season string
}

But when I marshal the Response object in my test code I don't see similar json. (https://play.golang.org/p/EGKqfbwFvW) Marshalled data always appears as :

{
  "Count":100,
  "Fruits":[
    {"Name":"Mango","Season":"Summer"},
    {"Name":"Fig","Season":"Winter"}
  ]
}

Notice the Fruits appearing as array [] and not {[]} in original json. How can I model structs in golang for this response?

Your model is totally correct and valid, but the JSON object is not. "Fruits" doesn't have name if it should be key value pair or it should be wrapped in [] not {}.

JSON obj should be formatted like this:

{
  "Basket" : {
    "Count": 1,
    "Fruits": [
      {
        "Name":"Mango", 
        "Season":"Summer"
      },
      {
        "Name":"Fig", 
        "Season":"Winter"
      }
    ]
  }
}

And actually invalid json shouldn't work https://play.golang.org/p/yoW7t4NfI7

I would make 'Baskets' a struct within 'Response', create a 'BasketsData' struct, and give it all some labels.

type Fruit struct {
    Name   string `json:"Name"`
    Season string `json:"Season"`
}

type BasketData struct {
    Count  int     `json:"Count"`
    Fruits []Fruit `json:"Fruits"`
}

type Response struct {
    Basket BasketData `json:"Basket"`
}

This way you will get a top level JSON response when you marshall it.

fruitmania := []Fruit{{Name: "Mango", Season: "Summer"},
                       {Name: "Fig", Season: "Winter"}}
basket := Response{BasketData{Count: 100, Fruits: fruitmania}}

b, _ := json.Marshal(basket)
fmt.Println(string(b))
