Getting Error While Code Upload - NODEMCU ESP8266 #6110
Description
Hi,
While am trying to upload the code from Arduino IDE to NODEMCU ESP8266 board getting some error can anyone help me to clear this error.
Program
#include <ESP8266HTTPClient.h>
#include <ESP8266WiFi.h>
#include <ArduinoJson.h>
char ssid[] = "MUGESH";
const char* password = "87654321";
void setup() {
Serial.begin(9600); //Serial connection
WiFi.begin(ssid, password); //WiFi connection
while (WiFi.status() != WL_CONNECTED) { //Wait for the WiFI connection completion
delay(500);
Serial.println("Waiting for connection");
}
Serial.println("WIFI Connected with : " + WiFi.localIP());
}
void loop() {
if (WiFi.status() == WL_CONNECTED) { //Check WiFi connection status
HTTPClient http; //Declare object of class HTTPClient
http.begin("https://jsonplaceholder.typicode.com/posts"); //Specify request destination
http.addHeader("Content-Type", "text/plain"); //Specify content-type header
int httpCode = http.GET(); //Send the request
String payload = http.getString(); //Get the response payload
StaticJsonDocument<500> jsonDoc;
// JsonObject& jsonObj = jsonBuffer.parseObject(payload);
deserializeJson(jsonDoc, payload);
serializeJsonPretty(jsonDoc, Serial);
Serial.println(httpCode); //Print HTTP return code
Serial.println(payload); //Print request response payload
http.end(); //Close connection
} else {
Serial.println("Error in WiFi connection");
}
delay(30000); //Send a request every 30 seconds
}
