[ESP8266] Json in sming Framework

Sming framework is a C++ framework for developing applications for ESP8266 and ESP32 microcontrollers. To encode and decode JSON data in Sming, you can use the JsonObjectStream library that is included in the framework.

 

Here's an example of encoding JSON data in Sming:

 

#include <JsonObjectStream.h>
#include <Wire.h>

void setup() {
  Serial.begin(115200);
  DynamicJsonDocument doc(1024);
  JsonObject data = doc.to<JsonObject>();
  data["device"] = "ESP8266";
  data["value"] = 42;
  String json;
  serializeJson(doc, json);
  Serial.println(json);
}

void loop() {
}

 

And here's an example of decoding JSON data in Sming:

#include <JsonObjectStream.h>
#include <Wire.h>

void setup() {
  Serial.begin(115200);
  String json = "{\"device\":\"ESP8266\",\"value\":42}";
  DynamicJsonDocument doc(1024);
  DeserializationError error = deserializeJson(doc, json);
  if (error) {
    Serial.println("Deserialization failed: " + error.c_str());
    return;
  }
  JsonObject data = doc.as<JsonObject>();
  Serial.println("device: " + data["device"].as<String>());
  Serial.println("value: " + data["value"].as<int>());
}

void loop() {
}
