Since I just stumbled upon that particular problem myself:
ArduinoJson has deprecated JsonBuffer in favour of JsonDocument, which is a nicer/better abstraction.
Also the printTo
method was removed in favour of a global serializeJson
method.
See https://arduinojson.org/v6/doc/upgrade/ for more details.
The above code using the new API should look like this:
AsyncCallbackJsonWebHandler *handler = new AsyncCallbackJsonWebHandler("/msg", [](AsyncWebServerRequest *request, JsonVariant &json)
{
JsonObject jsonObj = json.as<JsonObject>();
AsyncResponseStream *response = request->beginResponseStream("application/json");
DynamicJsonDocument jsonDoc(1024);
JsonObject root = jsonDoc.to<JsonObject>();
root["code"] = 200;
root["msg"] = "ok";
serializeJson(jsonDoc, *response);
request->send(response);
});

When i works on ArduinoJson 6.19.4 with AsyncCallbackJsonWebHandler looks like
It will be many errors like that DynamicJsonBuffer is noly works on ArduinoJson 5.
Colud be supports ArduinoJson 6+ ? Thanks.
