Go Systems Programming

Saving JSON data

This subsection will teach you how to convert regular data into JSON format in order to send it over a network connection. The Go code of this subsection will be saved as writeJSON.go and will be presented in four parts.

The first chunk of Go code is the expected preamble of the program as well as the definition of two new struct types named Record and Telephone, respectively:

package main 
 
import ( 
   "encoding/json" 
   "fmt" 
   "os" 
) 
 
type Record struct { 
   Name    string 
   Surname string 
   Tel     []Telephone 
} 
 
type Telephone struct { 
   Mobile bool 
   Number string 
}
