Fiber: Hi guys! how do i use BodyParser with a nested struct? 🤔🤔

[slalbertojesus]

I trying to use bodyparser to parse a nested struc from a form, do i have to specify something on field name?

For example

type Job struct {
    Type string `json:"type" xml:"type" form:"type"`
    Salary string `json:"salary" xml:"salary" form:"salary"`
}

type Person struct {
    Name string `json:"name" xml:"name" form:"name"`
    Pass string `json:"pass" xml:"pass" form:"pass"`
    Job Job `what goes on here?`
}

app.Post("/AddNewPerson", func(c *fiber.Ctx) {
        p := new(Person)

        if err := c.BodyParser(p); err != nil {
            log.Fatal(err)
        }

        log.Println(p.Name) // john
        log.Println(p.Job.Type) // software engineer
})

Sorry if this is a really obvious question, i am quite new to go and fiber

type Person struct {
    Name string `json:"name" xml:"name" form:"name"`
    Pass string `json:"pass" xml:"pass" form:"pass"`
    Job Job `json:"job" xml:"job" form:"job"`
}

You can also convert your payload to structs using https://mholt.github.io/json-to-go/

You can try this demo

package main

import (
    "github.com/gofiber/fiber"
    "log"
)

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

    type Job struct {
        Type   string `json:"type" xml:"type" form:"type"`
        Salary string `json:"salary" xml:"salary" form:"salary"`
    }

    type Person struct {
        Name string `json:"name" xml:"name" form:"name"`
        Pass string `json:"pass" xml:"pass" form:"pass"`
        Job  Job    `json:"job"` // or nothing to default
    }

    app.Post("/AddNewPerson", func(c *fiber.Ctx) {
        p := new(Person)

        if err := c.BodyParser(p); err != nil {
            log.Fatal(err)
        }

        c.SendString(p.Name + ":" + p.Job.Type)
    })

    log.Println(app.Listen(":3000"))
}

And the result

http post :3000/AddNewPerson name=jhon pass=pass job:='{"type":"software engineer"}'
