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\":\"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}}"]}`

I am putting it into this struc

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

and decode it with code

sReplace := strings.NewReplacer(`"{`, "{", `"]`, "]", "\\", ``) strN := sReplace.Replace(str) r := strings.NewReader(strN) d := json.NewDecoder(r) m := main{}

I am getting error

invalid character 'h' after object key:value pair

I know that the error is result of text field value. Is there any good way to clean it up or tell the decoder to ignore content of text field?

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) }

wow thank you very much I tried to figure it out whole day. This struc and json allways where hard for me :(
