从GoFrame v1.11
版本开始,Request
对象提供了对客户端提交的JSON/XML
数据格式的原生支持,为开发者提供了更便捷的数据获取特性,以进一步提高开发效率。
package main
import (
"github.com/gogf/gf/v2/frame/g"
"github.com/gogf/gf/v2/net/ghttp"
)
func main() {
s := g.Server()
s.BindHandler("/", func(r *ghttp.Request) {
r.Response.Writef("name: %v, pass: %v", r.Get("name"), r.Get("pass"))
})
s.SetPort(8199)
s.Run()
}
执行后,我们通过curl
工具提交数据来测试一下:
Query
数据格式$ curl "http://127.0.0.1:8199/?name=john&pass=123"
name: john, pass: 123
Form
表单提交$ curl -d "name=john&pass=123" "http://127.0.0.1:8199/"
name: john, pass: 123
JSON
数据格式$ curl -d '{"name":"john","pass":"123"}' "http://127.0.0.1:8199/"
name: john, pass: 123
XML
数据格式$ curl -d '<?xml version="1.0" encoding="UTF-8"?><doc><name>john</name><pass>123</pass></doc>' "http://127.0.0.1:8199/"
name: john, pass: 123
$ curl -d '<doc><name>john</name><pass>123</pass></doc>' "http://127.0.0.1:8199/"
name: john, pass: 123
package main
import (
"github.com/gogf/gf/v2/frame/g"
"github.com/gogf/gf/v2/net/ghttp"
"github.com/gogf/gf/v2/util/gvalid"
)
type RegisterReq struct {
Name string `p:"username" v:"required|length:6,30#请输入账号|账号长度为:min到:max位"`
Pass string `p:"password1" v:"required|length:6,30#请输入密码|密码长度不够"`
Pass2 string `p:"password2" v:"required|length:6,30|same:password1#请确认密码|密码长度不够|两次密码不一致"`
}
type RegisterRes struct {
Code int `json:"code"`
Error string `json:"error"`
Data interface{} `json:"data"`
}
func main() {
s := g.Server()
s.BindHandler("/register", func(r *ghttp.Request) {
var req *RegisterReq
if err := r.Parse(&req); err != nil {
// Validation error.
if v, ok := err.(gvalid.Error); ok {
r.Response.WriteJsonExit(RegisterRes{
Code: 1,
Error: v.FirstString(),
})
}
// Other error.
r.Response.WriteJsonExit(RegisterRes{
Code: 1,
Error: err.Error(),
})
}
// ...
r.Response.WriteJsonExit(RegisterRes{
Data: req,
})
})
s.SetPort(8199)
s.Run()
}
执行后,我们通过curl
工具提交数据来测试一下:
JSON
数据格式$ curl -d '{"username":"johngcn","password1":"123456","password2":"123456"}' "http://127.0.0.1:8199/register"
{"code":0,"error":"","data":{"Name":"johngcn","Pass":"123456","Pass2":"123456"}}
$ curl -d '{"username":"johngcn","password1":"123456","password2":"123"}' "http://127.0.0.1:8199/register"
{"code":1,"error":"两次密码不一致","data":null}
可以看到,我们提交的JSON
内容也被Parse
方法智能地转换为了结构体对象。
XML
数据格式$ curl -d '<?xml version="1.0" encoding="UTF-8"?><doc><username>johngcn</username><password1>123456</password1><password2>123456</password2></doc>' "http://127.0.0.1:8199/register"
{"code":0,"error":"","data":{"Name":"johngcn","Pass":"123456","Pass2":"123456"}}
$ curl -d '<?xml version="1.0" encoding="UTF-8"?><doc><username>johngcn</username><password1>123456</password1><password2>123</password2></doc>' "http://127.0.0.1:8199/register"
{"code":1,"error":"两次密码不一致","data":null}
可以看到,我们提交的XML
内容也被Parse
方法智能地转换为了结构体对象。
