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。

结果：
TEST
3.来自最好的总结
人生苦短，建议你还是用python吧！
