I have a go struct something like this
type Country struct {
WhoAllAreComing []string `json:"attendees"`
NameOfThePlace string `json:"name"`
EventDate string `json:"eventDate"`
}
This is the response struct that I need to send back after ingesting the input and manipulating it.
Now if suppose the EventDate
is empty, I need to pass a null in the json response and not an empty string. How do we convert an empty string in go to a null in json response.
Using json.Marshall
to marshall my response into Json is just converting it to empty string for EventDate.
Use a pointer to return a null instead of an empty string.
type Country struct {
WhoAllAreComing []string `json:"attendees"`
NameOfThePlace string `json:"name"`
EventDate *string `json:"eventDate"`
}
