下面是我依据网上资料的实操过程，记录以作备忘。该示例给出了https通信并处理json文件的例子。

平台：Ubuntu 16.04.3 LTS

go版本：1.10

1.生成自签名的服务器端的私钥KEY和公钥证书

openssl genrsa -out server.key 2048

openssl req -new -x509 -key server.key -out server.crt -days 3650  
![20180309102217414][]  
  
2.编写https通信的服务器和客户端程序  
server.go

package main
    
    import (
    	"encoding/json"
    	"fmt"
    	"net/http"
    )
    
    type MyData struct {
    	Name  string  `json:"item"`
    	Other float32 `json:"amount"`
    }
    
    //仅是构造一个json数据并发送给客户端
    func handler(w http.ResponseWriter, r *http.Request) {
    	var detail MyData
    	detail.Name = "1"
    	detail.Other = 2
    
    	body, err := json.Marshal(detail)
    	if err != nil {
    		panic(err.Error())
    	}
    
    	fmt.Fprintf(w, string(body))
    }
    
    func main() {
    	http.HandleFunc("/", handler)
    	fmt.Println("http server listen at 8086")
    	http.ListenAndServeTLS(":8086", "server.crt", "server.key", nil)
    }

client.go

package main
    
    import (
    	"crypto/tls"
    	"encoding/json"
    	"fmt"
    	"github.com/bitly/go-simplejson"
    	"io/ioutil"
    	"net/http"
    )
    
    type MyData struct {
    	Name  string  `json:"item"`
    	Other float32 `json:"amount"`
    }
    
    func main() {
    	tr := &http.Transport{
    		TLSClientConfig: &tls.Config{InsecureSkipVerify: true},
    	}
    
    	client := &http.Client{Transport: tr}
    
    	resp, err := client.Get("https://localhost:8086")
    	if err != nil {
    		fmt.Println("error:", err)
    		return
    	}
    
    	defer resp.Body.Close()
    
    	body, err := ioutil.ReadAll(resp.Body)
    	fmt.Println(string(body))
    
    	//decode json
    	js, err := simplejson.NewJson(body)
    	if err != nil {
    		panic(err.Error())
    	}
    	fmt.Printf("%T:%v\n", js, js)
    
    	var res MyData
    	err = json.Unmarshal([]byte(body), &res)
    	fmt.Println(res)
    	fmt.Println(res.Name, res.Other)
    }

3.安装client.go中需要的依赖库go-simplejson  
go get -v -u -t github.com/bitly/go-simplejson

4.编译生成服务器和客户端程序  
go build server.go  
go build client.go  
![201803091020461][]  
5.运行并看到结果  
打开两个终端，分别运行server和client程序

./server

./client
