这篇文章你可以学习到

1. Go使用Http 客户端调用
2. Go语言序列化或反序列化Json

1. Go使用Http 客户端调用

package util
import (
	"apigate/logger"
	"encoding/json"
	"io/ioutil"
	"net/http"
	"strings"
	"time"
)
const (
	JsonType = "application/json"
	timeOut = 5 * time.Second
)
func HttpPost(url string, page interface{}) []byte {
	timeout := time.Duration(timeOut)
	client := http.Client{
		Timeout: timeout,
	}
	data, err := json.Marshal(page)
	if err != nil {
		logger.Error(err)
		return nil
	}
	resp, err := client.Post(url, JsonType, strings.NewReader(string(data)))
	if err != nil {
		logger.Error(err)
		return nil
	}
	defer resp.Body.Close()
	body, err := ioutil.ReadAll(resp.Body)
	if err != nil {
		logger.Error(err)
		return nil
	}
	return body
}

2. Go语言序列化或反序列化Json

package mang
import (
	"apigate/logger"
	"apigate/util"
	"apigate/vo"
	"encoding/json"
	"github.com/tidwall/gjson"
	"os"
)
func ApiWhiteList(auth int) []vo.ApiWhiteListListVo {
	host := os.Getenv("OPERATE_HOST")
	if len(host) <= 0 {
		host = "http://127.0.0.1:19005"
	}
	whiteListUrl := host + "/v1/apiWhiteList/page"
	query := vo.ApiWhiteListQuery{}
	query.Number = 0
	query.Size = 50
	query.Auth = auth
	rsp := util.HttpPost(whiteListUrl, query)
	if rsp == nil {
		return nil
	}
	value := gjson.GetBytes(rsp, "content")
	logger.Info(value.String())
	var rspVo []vo.ApiWhiteListListVo
	err := json.Unmarshal([]byte(value.String()), &rspVo)
	if err != nil {
		logger.Error(err)
		return nil
	}
	return rspVo
}
