golangHow to get JSON data from HTTP request

package main

import ("net/http"; "io"; "encoding/json")

func main() {
  r, _ := http.Get("https://echoof.me/json")
  defer r.Body.Close()
  b, _ := io.ReadAll(r.Body)

}ctrl + cgithub

`package main` default package declaration	`net/http` http package to work with http protocol
`http.Get(` executes GET request to the specified URL	`https://echoof.me/json` returns request data in JSON format
`io.ReadAll(r.Body)` reads entire buffer (response body) into `b` bytes var	`var res map[string]interface{}` declare map to parse JSON with unknown structure into this variable
`json.Unmarshal` parses given JSON string (bytes) and saves result to `res`	`res["ip"].(string)` as example converts `ip` key of parsed json into string

Usage example

package main

import ("net/http"; "io"; "encoding/json")

func main() {
  r, _ := http.Get("https://echoof.me/json")
  defer r.Body.Close()
  b, _ := io.ReadAll(r.Body)

  var res map[string]interface{}
  json.Unmarshal(b, &res)
  print(res["ip"].(string))
}
