go代码

package main

import (
	"encoding/json"
	"fmt"
	"io/ioutil"
	"net/http"
	"time"

	simplejson "github.com/bitly/go-simplejson"
)



func main() {
	// 使用%252F转义"/"
	url := "http://192.168.111.xxx:8603/api/v2.0/projects/test/repositories/zhangxueliang%252Fmyapp/artifacts"
	resp, err := http.Get(url)
	if err != nil {
		fmt.Println("报错了")
		return
	}
	body, _ := ioutil.ReadAll(resp.Body)
	var rr []map[string]interface{}
	json.Unmarshal(body, &rr)
	for _, v := range rr {
		b, _ := json.Marshal(v)
		sj, err := simplejson.NewJson(b)
		if err != nil {
			panic(err)
		}
		tags, err := sj.Get("tags").Array()
		fmt.Println(tags)
	}
}

结果 解析出name字段

// fmt.Println(tags)
		for _, value := range tags {
			tagname, _ := value.(map[string]interface{})
			fmt.Println(tagname["name"])
		}

如果不进行断言判断，就会报错：
