NF Web Framework

Usage

basic usage

• get param

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

    app.Get("/hello/:name", func(c *nf.Ctx) error {
        name := c.Param("name")
        return c.JSON(nf.Map{"status": 200, "data": "hello, " + name})
    })

    log.Fatal(app.Run("0.0.0.0:80"))
}

• parse request query

func handleQuery(c *nf.Ctx) error {
    type Req struct {
        Name string   `query:"name"`
        Addr []string `query:"addr"`
    }

    var (
        err error
        req = Req{}
    )

    if err = c.QueryParser(&req); err != nil {
        return nf.NewNFError(400, err.Error())
	}

    return c.JSON(nf.Map{"query": req})
}

• parse application/json body

func handlePost(c *nf.Ctx) error {
    type Req struct {
        Name string   `json:"name"`
        Addr []string `json:"addr"`
    }

    var (
        err error
        req = Req{}
		reqMap = make(map[string]any)
    )
	
    if err = c.BodyParser(&req); err != nil {
        return nf.NewNFError(400, err.Error())
    }
	
    // can parse body multi times
    if err = c.BodyParser(&reqMap); err != nil {
        return nf.NewNFError(400, err.Error())
    }
	
    return c.JSON(nf.Map{"struct": req, "map": reqMap})
}
