這篇文章主要講解了“Golang如何實(shí)現(xiàn)Json轉(zhuǎn)結(jié)構(gòu)體”,文中的講解內(nèi)容簡(jiǎn)單清晰,易于學(xué)習(xí)與理解,下面請(qǐng)大家跟著小編的思路慢慢深入,一起來(lái)研究和學(xué)習(xí)“Golang如何實(shí)現(xiàn)Json轉(zhuǎn)結(jié)構(gòu)體”吧!
1.請(qǐng)求Zabbix API,通過(guò)itemid獲取到AppName(應(yīng)用集名稱)
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) }
響應(yīng)結(jié)果:
{"jsonrpc":"2.0","result":[{"applicationid":"1574","hostid":"10354","name":"TEST","flags":"0","templateids":[]}],"id":2}
2.將響應(yīng)結(jié)果(json)轉(zhuǎn)結(jié)構(gòu)體,方便取值
在原來(lái)代碼的基礎(chǔ)上,繼續(xù)編碼。
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) }
結(jié)果:
TEST
