从map [string] string获取单个键值

Question

I have a map being stored in my cookie as followed:

cookieData:=   map[expiration:1533455712 ip:[ hash:dd363d13234566727743277e96 email:[e-mail]]

fmt.Println(reflect.TypeOf(cookie)) >> map[string]string

Can someone please help me understand how i can get only the email value from this map?

Thanks in advance.

type casting in golang is done by appending .(T)

ip := cookieData["ip"].(map[string]string)
email := ip["email"]
