6.json反序列化为map

json反序列化为map ~~~ package main import ( "encoding/json" "fmt" "reflect" ) func testMap() (ret string, err error) { var m map[string]interface{} m = make(map[string]interface{}) m["username"] = "user1" m["age"] = 18 m["sex"] = "man" data, err := json.Marshal(m) if err != nil { err = fmt.Errorf("json.marshal failed, err:", err) return } ret = string(data) return } func test2() { data, err := testMap() if err != nil { fmt.Println("test map failed, ", err) return } var m map[string]interface{} err = json.Unmarshal([]byte(data), &m) if err != nil { fmt.Println("Unmarshal failed, ", err) return } fmt.Println(m) fmt.Println(reflect.TypeOf(m)) } func main() { test2() } ~~~ 输出结果： ~~~ map[sex:man username:user1 age:18] map[string]interface {} ~~~
