Introduction

You can use ctx.Response() for HTTP response in the Controller.

String

import "github.com/goravel/framework/contracts/http"  ctx.Response().String(http.StatusOK, "Hello Goravel")

JSON

import (  "github.com/goravel/framework/contracts/http" )  ctx.Response().Json(http.StatusOK, http.Json{  "Hello": "Goravel", })  ctx.Response().Json(http.StatusOK, struct {  ID uint `json:"id"`  Name string `json:"name"` }{  Id: 1,  Front: "Goravel", })

Custom Return

ctx.Response().Data(http.StatusOK, "text/html; charset=utf-8", []byte("<b>Goravel</b>"))

Response File

import "net/http"  ctx.Response().File("./public/logo.png")

Download File

import "net/http"  ctx.Response().Download("./public/logo.png", "1.png")

Attach Header

import "github.com/goravel/framework/contracts/http"  ctx.Response().Header("Content", "Goravel").String(http.StatusOK, "Hello Goravel")

Cookie

Set Cookie

Use the Cookie method on the response instance to set a cookie. The Cookie method accepts a http.Cookie instance, which allows you to set various cookie options.

import (  "time"  "github.com/goravel/framework/contracts/http" )  ctx.Response().Cookie(http.Cookie{  Name: "name",  Value: "Goravel",  Path: "/",  Domain: "goravel.dev",  Expires: time.Now().Add(24 * time.Hour),  Secure: true,  HttpOnly: true, })

Expire Cookie

Use the WithoutCookie method to remove a cookie.

ctx.Response().WithoutCookie("name")

Return Success

ctx.Response().Success().String("Hello Goravel") ctx.Response().Success().Json(http.Json{  "Hello": "Goravel", })

Custom Code

ctx.Response().Status(http.StatusOK).Json(http.Json{  "hello": "Goravel", })

Return Stream

ctx.Response().Stream(http.StatusCreated, func(w http.StreamWriter) error {  data := []string{"a", "b", "c"}  for _, item := range data {  if _, err := w.Write([]byte(item + "\n")); err != nil {  return err  }   if err := w.Flush(); err != nil {  return err  }   time.Sleep(1 * time.Second)  }   return nil })

Redirect

ctx.Response().Redirect(http.StatusMovedPermanently, "https://goravel.dev")

No Content

ctx.Response().NoContent() ctx.Response().NoContent(http.StatusOk)

Get Response

You can obtain all the information from ctx.Response(), which is commonly used in HTTP middleware:

origin := ctx.Response().Origin()

origin contains some methods as shown below：

Method	Action
Body	Get response data
Header	Get response header
Size	Get response size
Status	Get response status
