Golang Deep Copy Map

This is a created article in which the information may have evolved or changed.

The simplest way to do this is to use the JSON Unmarshal to become a string, and then use the JSON marshal to generate a new map. This method is also applicable to structural bodies.

If it's a combination of map[string]interface{} and []interface{}, it's simple to use code recursion:

Func deepcopy (Value interface{}) interface{} {if valueMap, OK: = value. ( map[string]interface{}); OK {newmap: = Make (map[string]interface{}) for k, V: = range ValueMap {newmap[k] = deepcopy (v)}return Newmap} else if value Slice, OK: = value. ([]interface{}); OK {newslice: = make ([]interface{}, Len (Valueslice)) for k, V: = range Valueslice {newslice[k] = deepcopy (v)}return newslic E}return Value}
