stackoverflow解决: ```go var mylist []interface{} = enc["actions"].([]interface{}) mylist = append(mylist, "good") enc["actions"] = mylist ```

就是加一个断言 ```go if v, ok := enc["actions"]; ok { if nv, ok := v.([]interface{}); ok { nv = append(nv, "good") enc["actions"] = nv } } else { enc["actions"] = []interface{}{"good"} } ```
