decode json including json encoded strings

Question

Hey guys I am getting websocket information from external Api and it\'s give me json response in this way:

 `{\"name\":\"message\",\"args\":[\"{\\\"method\\\":\\         


        

Answer 1

The application is parsing data containing the substring "text":"<a href="https. This is not valid JSON. The error message is complaining about the h in href.

Because the JSON value includes encoded JSON values, the application must decode in two steps:

type main struct {
  Name string   `json:"name"`
  Args []string `json:"args"`
}

type arg struct {
  Method string `json:"method"`
  Params par    `json:"params"`
}
type par struct {
  Channel   string `json:"channel,omitempty"`
  Name      string `json:"name,omitempty"`
  NameColor string `json:"nameColor,omitempty"`
  Text      string `json:"text,omitempty"`
  Time      int64  `json:"time,omitempty"`
}

str := `{"name":"message","args":["{\"method\":\"chatMsg\",\"params\":{\"channel\":\"channel\",\"name\":\"name\",\"nameColor\":\"B5B11E\",\"text\":\"<a href=\\\"https://play.spotify.com/browse\\\" target=\\\"_blank\\\">https://play.spotify.com/browse</a>\",\"time\":1455397119}}"]}`
var m main
if err := json.Unmarshal([]byte(str), &m); err != nil {
    log.Fatal(err)
}
var args arg
if err := json.Unmarshal([]byte(m.Args[0]), &args); err != nil {
    log.Fatal(err)
}
