package main import ( "fmt" "encoding/json" ) func main() { // json encode j1 := make(map[string]interface{}) j1["name"] = "outofmemory" j1["url"] = "http://outofmemory.cn/" js1, err := json.Marshal(j1) if err != nil { panic(err) } println(string(js1)) // json decode j2 := make(map[string]interface{}) err = json.Unmarshal(js1, &j2) if err != nil { panic(err) } fmt.Printf("%#v\n", j2) }
