JSON响应结构

Question

I'm trying to workout how the type-struct should be for this JSON response. from CryptoWatch https://api.cryptowat.ch/markets/kraken/btcusd/ohlc?periods=60

{
  "result": {
    "60": [
      [
        1490733900,
        1027.001,
        1027.001,
        1027,
        1027,
        0.024999999
      ],
      [
        1490733960,
        1027,
        1027,
        1027,
        1027,
        12.61904
      ],
      [
        1490778360,
        1037.749,
        1037.749,
        1037.749,
        1037.749,
        0.0052474597
      ]
    ]
  },
  "allowance": {
    "cost": 1234,
    "remaining": 456677
  }
}

1. I've tried the JSON-TO-GoLang-Struct service.

   type AutoGenerated struct { Result struct { Num60 []struct { Num0 int json:"0" Num1 float64 json:"1" Num2 float64 json:"2" Num3 int json:"3" Num4 int json:"4" Num5 float64 json:"5" } json:"60" } json:"result" Allowance struct { Cost int json:"cost" Remaining int json:"remaining" } json:"allowance" }

   code-formatting seems broken :/

It seems to get stuck on array-to-struct error when i tried to decode it.

1. I don't want to use the map+interface method for this struct.

Answer 1

Here you go. You can put the result as map[string][][]float64 also. But this is more readable I think.

type Result [][]float64

type Response struct {
    Result    map[string]Result `json:"result"`
    Allowance struct {
        Cost      int `json:"cost"`
        Remaining int `json:"remaining"`
    } `json:"allowance"`
}
