Removing fields from struct or hiding them in JSON Response

Question

I\'ve created an API in Go that, upon being called, performs a query, creates an instance of a struct, and then encodes that struct as JSON before sending back to the caller

Answer 1

Here is how I defined my structure.

type User struct {
    Username string  `json:"username" bson:"username"`
    Email    string  `json:"email" bson:"email"`
    Password *string `json:"password,omitempty" bson:"password"`
    FullName string  `json:"fullname" bson:"fullname"`
}

And inside my function set user.Password = nil for not to be Marshalled.
