How do I construct and send a JSON array with Go?
For example:
{ myArray: ["one", "two", "three"] }
At the moment the closest I can get it sending JSON down to the browser as a string like this:
{ myArrayString: '["once", "two", "three"]' }
Which is not what I'm trying to achieve.
Quite straightforward as @swoogan comments:
package main
import (
"encoding/json"
"fmt"
)
type myJSON struct {
Array []string
}
func main() {
jsondat := &myJSON{Array: []string{"one", "two", "three"}}
encjson, _ := json.Marshal(jsondat)
fmt.Println(string(encjson))
}
Demo avaliable here.
You need to import "encoding/json" and then use json.Marshal with your structure.
