How do I return a struct as json using fiber in golang?

Question

Since I couldn't find any tutorial on internet about this simple problem, I must write here to get help.

I have this function:

package main

import (
    "encoding/json"

    "github.com/gofiber/fiber/v2"
)


type Person struct {
    email string
}

func main() {
    app := fiber.New()

    app.Get("/", func(c *fiber.Ctx) error {
        user := Person{
            email: "[email protected]",
        }

        u, err := json.Marshal(user);

        if err != nil {
            panic(err)
        }

        return c.JSON(u);
    })

    app.Listen(":5000")
}

But when I visit 127.0.0.1:5000, it says: "e30=" instead of the user json. How do I do it?

See this

type Person struct { Email string }

Your member of struct must be uppercase,then json.Marshal will work

Change

return c.JSON(u)

To

return c.SendString(string(u))

If Using c.JSON It Will Turn Your String Be Base64 format

package main

import (
    "encoding/json"

    "github.com/gofiber/fiber/v2"
    "fmt"
)


type Person struct {
    Email string
}

func main() {
    app := fiber.New()

    app.Get("/", func(c *fiber.Ctx) error {
        user := Person{
            Email: "[email protected]",
        }
        fmt.Println(user)
        u, err := json.Marshal(user);

        if err != nil {
            panic(err)
        }
        fmt.Println(u)
        fmt.Println(string(u))
        return c.SendString(string(u))
    })

    app.Listen(":5000")
}
