相关方法:
func (r *Response) WriteJson(content interface{}) error
func (r *Response) WriteJsonExit(content interface{}) error
func (r *Response) WriteJsonP(content interface{}) error
func (r *Response) WriteJsonPExit(content interface{}) error
func (r *Response) WriteXml(content interface{}, rootTag ...string) error
func (r *Response) WriteXmlExit(content interface{}, rootTag ...string) errorResponse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。
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/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。

import (

)
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"
