前往：将JSON字符串转换为map [string] interface {}

Question

I'm trying to create a JSON representation within Go using a map[string]interface{} type. I'm dealing with JSON strings and I'm having a hard time figuring out how to avoid the JSON unmarshaler to automatically deal with numbers as float64s. As a result the following error occurs.

Ex. "{ 'a' : 9223372036854775807}" should be map[string]interface{} = [a 9223372036854775807 but in reality it is map[string]interface{} = [a 9.2233720368547758088E18]

I searched how structs can be used to avoid this by using json.Number but I'd really prefer using the map type designated above.
