复杂MAP取值问题

我有一个Map如下 { "status": "success", "data": { "resultType": "vector", "result": [{ "metric": { "__name__": "up", "alias": "xxxxx", "instance": "xxxxx", "job": "consul-prometheus" }, "value": [1562051593.673, "1"] }, { "metric": { "__name__": "up", "alias": "xxxx", "instance": "xxxxx", "job": "consul-prometheus" }, "value": [1562051593.673, "1"] }] } } 我想取value里面的每一个值与第二个值，如何取 代码只能取到result就不会了 package main import ( "encoding/json" "fmt" ) func main() { json_strnew := ` { "status": "success", "data": { "resultType": "vector", "result": [{ "metric": { "__name__": "up", "alias": "xxxxx", "instance": "xxxxx", "job": "consul-prometheus" }, "value": [1562051593.673, "1"] }, { "metric": { "__name__": "up", "alias": "xxxx", "instance": "xxxxx", "job": "consul-prometheus" }, "value": [1562051593.673, "1"] }] } } ` m := make(map[string]interface{}) err := json.Unmarshal([]byte(json_strnew), &m) fmt.Println(err) if err != nil { fmt.Println(err) } else { for k, v := range m["data"].(map[string]interface{}) { fmt.Printf("%s:%s;\n", k, v) fmt.Println(v) //for kk, vv := range v { // fmt.Printf("%s=%s;\n", kk, vv) //} } } }
