Codec JSON kustom saat runtime

Gin mendukung logika serialisasi dan deserialisasi JSON kustom tanpa menggunakan tag kompilasi.

1. Definisikan struct kustom yang mengimplementasikan antarmuka json.Core.
2. Sebelum engine Anda dimulai, tetapkan nilai ke json.API menggunakan struct kustom.

package main

import (
  "io"

  "github.com/gin-gonic/gin"
  "github.com/gin-gonic/gin/codec/json"
  jsoniter "github.com/json-iterator/go"
)

var customConfig = jsoniter.Config{
  EscapeHTML:             true,
  SortMapKeys:            true,
  ValidateJsonRawMessage: true,
}.Froze()

type customJsonApi struct{}

func (j customJsonApi) Marshal(v any) ([]byte, error) {
  return customConfig.Marshal(v)
}

func (j customJsonApi) Unmarshal(data []byte, v any) error {
  return customConfig.Unmarshal(data, v)
}

func (j customJsonApi) MarshalIndent(v any, prefix, indent string) ([]byte, error) {
  return customConfig.MarshalIndent(v, prefix, indent)
}

func (j customJsonApi) NewEncoder(writer io.Writer) json.Encoder {
  return customConfig.NewEncoder(writer)
}

func (j customJsonApi) NewDecoder(reader io.Reader) json.Decoder {
  return customConfig.NewDecoder(reader)
}

func main() {
  // Replace the default json api
  json.API = customJsonApi{}

  // Start your gin engine
  router := gin.Default()
  router.Run(":8080")
}
