我试图返回array []Employee作为响应。Is具有len 2。但postman显示响应体为空。

type People struct {
    Height         int32          `json:"height" binding:"required"`
        Weight         int32          `json:"weight" binding:"required"`
}

type Employee struct {
    Salary int `json:"salary"`
    People
}

c.JSON(http.StatusOK, employeeArray)

我在google里发现golang有一些内部绑定结构的问题。
UPD：使用MarshalJSON重写的代码。

package main

import (
    "github.com/gin-gonic/gin"
    "net/http"
)

type TypeName struct {
    Name string `json:"name" binding:"required"`
}

func (p TypeName) MarshalJSON() ([]byte, error) {
    return []byte("Joe"), nil
}

type People struct {
    Height int32 `json:"height" binding:"required"`
    Weight int32 `json:"weight" binding:"required"`
    TypeName
}

type Employee struct {
    Salary int `json:"salary"`
    People
}

func main() {
    r := gin.Default()

    r.GET("/employees", func(c *gin.Context) {
        employeeArray := []Employee{
            {
                Salary: 10000,
                People: People{
                    Height: 170,
                    Weight: 80,
                },
            },
            {
                Salary: 20000,
                People: People{
                    Height: 175,
                    Weight: 80,
                },
            },
        }

        c.JSON(http.StatusOK, employeeArray)
    })
    _ = r.Run()
}
