关于go:GoJson转结构体

解决理论需要，案例分享。

1. 申请Zabbix API，通过itemid获取到AppName（利用集名称）

   package mainimport ( "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)}

   响应后果：

   {"jsonrpc":"2.0","result":[{"applicationid":"1574","hostid":"10354","name":"TEST","flags":"0","templateids":[]}],"id":2}

2. 将响应后果（json）转构造体，不便取值

   在原来代码的根底上，持续编码。

   package mainimport ( "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 []resultInfotype Response struct { Jsonrpc string    `json:"jsonrpc"` Result  resultArr `json:result` Id      int       `json:"id"`}type Byte []bytefunc 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)}

   后果：

   TEST

3. 来自最好的总结

   人生苦短，倡议你还是用python吧！
