吐槽一句，没有泛型真的很头大- -

Json 统一解析的一种办法

package json

import (

"encoding/json"

"testing"

)

type (

Result struct {

Code int `json:"code"`

Message string `json:"message"`

Data json.RawMessage `json:"data"`

}

TickersResult struct {

Tickers []struct {

ID string `json:"_id"`

DisplayPairName string `json:"display_pair_name"`

Price float64 `json:"price"`

Volume float64 `json:"volume"`

} `json:"tickers"`

}

Student struct {

Name string `json:"name"`

Class string `json:"class"`

Weight float64 `json:"weight"`

Age int `json:"age"`

}

IBean interface{ Tag() }

)

func (*TickersResult) Tag() {}

func (*Student) Tag() {}

func (r *Result) ParseData(iBean IBean) IBean {

if err := json.Unmarshal([]byte(r.Data), &iBean); err != nil {

return nil

}

return iBean

}

func TestJson(t *testing.T) {

tickersJsonBytes := []byte(`{"code": 0, "message": "success", "data": { "tickers": [ { "_id": "5a33741cce79d2cf9bf5942c", "display_pair_name": "EOS/KRW", "price": 12.5284441, "volume": 202401841.79944953 }]}}`)

var result Result

if err := json.Unmarshal(tickersJsonBytes, &result); err != nil {

t.Fatal(err)

}

var tickersResult TickersResult

t.Log(result.ParseData(&tickersResult))

studentJsonBytes := []byte(`{"code":0,"message":"success","data":{"name":"5a33741cce79d2cf9bf5942c","class":"A109","weight":12.5284441,"age":20}}`)

var studentResult Result

if err := json.Unmarshal(studentJsonBytes, &studentResult); err != nil {

t.Fatal(err)

}

var student Student

t.Log(studentResult.ParseData(&student))

}

我记得还有一种办法的，一时给忘了，记得再补上，希望对各位有所帮助。
