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
。
对
JSON
数据格式支持的同时,同时也支持JSONP
协议。
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()
}
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"}
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/frame/g"
"github.com/gogf/gf/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"})
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()
}
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>
