JSON/XML输出

接口文档:https://godoc.org/github.com/gogf/gf/net/ghttp#Response

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:

  1. WriteJson* 方法用于返回JSON数据格式,参数为任意类型,可以为stringmapstruct等等。返回的Content-Typeapplication/json
  2. WriteXml* 方法用于返回XML数据格式,参数为任意类型,可以为stringmapstruct等等。返回的Content-Typeapplication/xml

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()
}

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/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"})

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()
}

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>
