...

对JSON数据格式支持的同时，同时也支持JSONP协议。

JSON

package main

import (
	"github.com/gogf/gf/frame/g"
	"github.com/gogf/gf/net/ghttp"
)

func main() {
	s := g.Server()
	s.Group("/", func(group *ghttp.RouterGroup) {
		group.ALL("/json", func(r *ghttp.Request) {
			r.Response.WriteJson(g.Map{
				"id":   1,
				"name": "john",
			})
		})
	})
	s.SetPort(8199)
	s.Run()
}

...

$ curl -i http://127.0.0.1:8199/json
HTTP/1.1 200 OK
Content-Type: application/json
Server: GF HTTP Server

{"id":1,"name":"john"}

JSONP

需要注意使用JSONP协议时必须通过Query方式提供callback参数。

...

$ curl -i "http://127.0.0.1:8199/jsonp?callback=MyCallback"
HTTP/1.1 200 OK
Server: GF HTTP Server
Date: Sun, 05 Jan 2020 02:50:42 GMT
Content-Length: 34
Content-Type: text/plain; charset=utf-8

MyCallback({"id":1,"name":"john"})

XML

package main

import (
	"github.com/gogf/gf/frame/g"
	"github.com/gogf/gf/net/ghttp"
)

func main() {
	s := g.Server()
	s.Group("/", func(group *ghttp.RouterGroup) {
		group.ALL("/xml", func(r *ghttp.Request) {
            r.Response.Write(`<?xml version="1.0" encoding="UTF-8"?>`)
			r.Response.WriteXml(g.Map{
				"id":   1,
				"name": "john",
			})
		})
	})
	s.SetPort(8199)
	s.Run()
}
