这个是本人学习之用,比较乱

我也不知道这是在教大家什么,但如果你能看懂,那你就能真正干活了

//https-ajax.go

package main

import (
"fmt"
"io"
"net/http"
"encoding/json"
"github.com/bitly/go-simplejson"
)

func OnAjax(res http.ResponseWriter, req *http.Request) {
query := req.URL.Query()
fmt.Println("get ", len(query))
if len(query["param1"]) > 0 {
fmt.Println("get ", query["param1"][0])
}
if len(query["param2"]) > 0 {
fmt.Println("get ", query["param2"][0])
}

var detail MyData

detail.Name = "1"
detail.Other = 2.0789

body, err := json.Marshal(detail)
if err != nil {
panic(err.Error())
}
fmt.Println("body ", body)
fmt.Println("string body ", string(body))

js, err := simplejson.NewJson(body)
if err != nil {
panic(err.Error())
}
fmt.Printf("%T:%v\n",js,js)
_map,_ := js.Map()
fmt.Println("map ", _map)
fmt.Println("js count ", len(_map))
item := js.Get("item")
fmt.Println("item ", item.MustString())
amount := js.Get("amount")
//fmt.Println("amount ", amount.MustBool())
fmt.Println("amount ", amount.MustFloat64())

//io.WriteString(res, "These are data from server")
io.WriteString(res, string(body))
}

func OnRes(res http.ResponseWriter, req *http.Request) {
req.ParseForm()
fmt.Println("post", req.PostForm)
fmt.Println("post param1 ", req.PostFormValue("param1"))
fmt.Println("post param2 ", req.PostFormValue("param2"))
io.WriteString(res, "infosec")
}

type MyData struct {
Name string `json:"item"`
Other float32 `json:"amount"`
}

func main() {
//static web
http.Handle("/", http.FileServer(http.Dir("web")))
//dynamic web
http.HandleFunc("/ajax", OnAjax)
http.HandleFunc("/infosec", OnRes)

// start server
fmt.Println("Server is running at localhost:8086")
//err := http.ListenAndServe(":8086", nil)
err := http.ListenAndServeTLS(":8086", "server.crt", "server.key", nil)
if err != nil {
fmt.Println("Server failure /// ", err)
