Response
提供了对JSON/XML
数据格式输出的原生支持,通过以下方法实现:
WriteJson*
方法用于返回JSON
数据格式,参数为任意类型,可以为string
、map
、struct
等等。返回的Content-Type
为application/json
。WriteXml*
方法用于返回XML
数据格式,参数为任意类型,可以为string
、map
、struct
等等。返回的Content-Type
为application/xml

JSON
package main import ( "github.com/gogf/gf/v2/frame/g" "github.com/gogf/gf/v2/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() } |
执行后,我们通过curl
工具测试下:
$ curl -i http://127.0.0.1:8199/json HTTP/1.1 200 OK Content-Type: application/json Server: GF HTTP Server Date: Sun, 05 Jan 2020 02:49:31 GMT Content-Length: 22 {"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。
package main import ( "github.com/gogf/gf/v2/frame/g" "github.com/gogf/gf/v2/net/ghttp" ) func main() { s := g.Server() s.Group("/", func(group *ghttp.RouterGroup) { group.ALL("/jsonp", func(r *ghttp.Request) { r.Response.WriteJsonP(g.Map{ "id": 1, "name": "john", }) }) }) s.SetPort(8199) s.Run() } |
执行后,我们通过curl
工具测试下:
$ 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/v2/frame/g" "github.com/gogf/gf/v2/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() } |
执行后,我们通过curl
工具测试下:
$ curl -i http://127.0.0.1:8199/xml HTTP/1.1 200 OK Content-Type: application/xml Server: GF HTTP Server Date: Sun, 05 Jan 2020 03:00:55 GMT Content-Length: 76 <?xml version="1.0" encoding="UTF-8"?><doc><id>1</id><name>john</name></doc> |
