    Age      int    `validate:"isInt"`
}

Use in controller

package app

import "github.com/tinh-tinh/tinhtinh/core"

func Controller(module *core.DynamicModule) *core.DynamicController {
    ctrl := module.NewController("test")
    
    ctrl.Pipe(core.Body(&SignUpDto{})).Post("", func (ctx core.Ctx) error {
        return ctx.JSON(core.Map{
            "data": ctx.Body(),
        })
    })
    
    return ctrl
}

Query

Define dto for query

package app

import "github.com/tinh-tinh/tinhtinh/core"

type FilterDto struct {
    Name  string `validate:"required" query:"name"`
    Email string `validate:"required,isEmail" query:"email"`
    Age   int    `validate:"isInt" query:"age"`
}

func Controller(module *core.DynamicModule) *core.DynamicController {
    ctrl := module.NewController("test")
    
    ctrl.Pipe(core.Query(&FilterDto{})).Post("", func (ctx core.Ctx) error {
        return ctx.JSON(core.Map{
            "data": ctx.Queries(),
        })
    })
    
    return ctrl
}

Param

Define dto for params

package app

import "github.com/tinh-tinh/tinhtinh/core"

type ParamDto struct {
    ID int `validate:"required,isInt" param:"id"`
}

func Controller(module *core.DynamicModule) *core.DynamicController {
    ctrl := module.NewController("test")
    
    ctrl.Pipe(core.Param(&ParamDto{})).Get("{id}", func (ctx core.Ctx) error {
        return ctx.JSON(core.Map{
            "data": ctx.Params(),
        })
    })
    
    return ctrl
}
