解决实际需求，案例分享。
1.请求Zabbix API，通过itemid获取到AppName（应用集名称）
package main
import (
"encoding/json"
"fmt"
"io/ioutil"
"log"
"net/http"
"strings"
)
func PostRequest(payload string, url string) {
method := "POST"
pl := strings.NewReader(payload)
client := &http.Client{}
req, err := http.NewRequest(method, url, pl)
if err != nil {
fmt.Println(err)
return
}
req.Header.Add("Content-Type", "application/json")
res, err := client.Do(req)
if err != nil {
fmt.Println(err)
return
}
defer res.Body.Close()
body, err := ioutil.ReadAll(res.Body)
if err != nil {
log.Println(err)
return
}
fmt.Println(string(body))
}
func main() {
const api = "http://192.168.11.11:28080/api_jsonrpc.php"
const token = "a638200c24a8bea7f78cd5cabf3d1dd5"
const itemid = "33918"
a := fmt.Sprintf(`{
"jsonrpc": "2.0",
"method": "application.get",
"params": {"itemids": "%s"},
"auth": "%s","id": 2
}`, itemid, token)
PostRequest(a, api)
}
响应结果：
{"jsonrpc":"2.0","result":[{"applicationid":"1574","hostid":"10354","name":"TEST","flags":"0","templateids":[]}],"id":2}
2.将响应结果（json）转结构体，方便取值
在原来代码的基础上，继续编码。
package main
import (
"encoding/json"
"fmt"
"io/ioutil"
"log"
"net/http"
"strings"
)
type resultInfo struct {
Applicationid string `json:"applicationid"`
Hostid string `json:"hostid"`
Name string `json:"name"`
Flags string `json:"flags"`
Templateids []string `json:"templateids"`
}
type resultArr []resultInfo
type Response struct {
Jsonrpc string `json:"jsonrpc"`
Result resultArr `json:result`
Id int `json:"id"`
}
type Byte []byte
func JsonConvertStruct(body Byte) {
var response Response
json.Unmarshal([]byte(body), &response)
fmt.Println(response.Result[0].Name)
}
func PostRequest(payload string, url string) {
method := "POST"
pl := strings.NewReader(payload)
client := &http.Client{}
req, err := http.NewRequest(method, url, pl)
if err != nil {
fmt.Println(err)
return
}
req.Header.Add("Content-Type", "application/json")
res, err := client.Do(req)
if err != nil {
fmt.Println(err)
return
}
defer res.Body.Close()
body, err := ioutil.ReadAll(res.Body)
if err != nil {
log.Println(err)
return
}
JsonConvertStruct(body)
}
func main() {
const api = "http://192.168.11.11:28080/api_jsonrpc.php"
const token = "a638200c24a8bea7f78cd5cabf3d1dd5"
const itemid = "33918"
a := fmt.Sprintf(`{
"jsonrpc": "2.0",
"method": "application.get",
"params": {"itemids": "%s"},
"auth": "%s","id": 2
}`, itemid, token)
PostRequest(a, api)
}
结果：
TEST
3.来自最好的总结
人生苦短，建议你还是用python吧！
