What did you do?

json marshal output not expect

package main

import (
	"encoding/json"
	"fmt"
	"log"
)

func main() {
	c := &C{
		Age:  30,
		Addr: "shanghai",
		A: A{
			Age:  10,
			Name: "aa",
		},
		B: B{
			Age:  20,
			Name: "bb",
		},
	}

	b, err := json.Marshal(c)
	if err != nil {
		log.Fatal(err)
	}

	fmt.Println("b:", string(b))
	// Output:
	// b: {"age":30,"addr":"shanghai"}
}

type A struct {
	Age  int    `json:"age"`
	Name string `json:"name"`
}

type B struct {
	Age  int    `json:"age"`
	Name string `json:"name"`
}

type C struct {
	Age  int    `json:"age"`
	Addr string `json:"addr"`
	A
	B
}

What did you see happen?

{"age":30,"addr":"shanghai"}

What did you expect to see?

{"age":30,"addr":"shanghai","name":"bb"}

This is the same as go field promotion, if there are conflicts in embedded structs, neither is promoted.

Unlike many projects, the Go project does not use GitHub Issues for general discussion or asking questions. GitHub Issues are used for tracking bugs and proposals only.
