I am trying to open load a webpage from ESP8266 that displays temperature and humidity of my room if I only type root URL:192.168.1.89

GET / HTTP/1.1
Host: 192.168.1.89
Connection: keep-alive
Upgrade-Insecure-Requests: 1
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12) AppleWebKit/602.1.50 (KHTML, like Gecko) Version/10.0 Safari/602.1.50
Accept-Language: en-us
DNT: 1
Accept-Encoding: gzip, deflate

to do that in my esp8266 sketch I am trying this logic:

bool readRequest(WiFiClient& client) {
  bool currentLineIsBlank = true;
  while (client.connected()) {
    if (client.available()) {
      char c = client.read();
      if (c == "GET / HTTP/1.1"){
        Serial.println("Got root");
        client.println(handleRoot()); // where handle root contains web page
      }
      else{
        Serial.println("Did not got root.");
      }
      if (c == '\n' && currentLineIsBlank) {

        return true;
      } else if (c == '\n') {
        currentLineIsBlank = true;
      } else if (c != '\r') {
        currentLineIsBlank = false;
      }
    }
  }
  return false;
}

but the condition to check if it met GET / HTTP/1.1 never validates.

    c is a char. You can't compare a char to a string. And c == "GET... is not how you compare string in C, anyway. – user31481 Nov 23 '17 at 14:54
  • Just use a HTTP server library. – gre_gor Nov 23 '17 at 14:58
  • @gre_gor in a different project I am using ESP8266WebServer but I want ed to give a try to WiFiServer server(80); while sticking with ArduinoJson.h library as well. – Ciasto piekarz Nov 23 '17 at 15:06

    This applies to networking as well as serial. Also this may be of use to you, along with this. – Majenko Nov 23 '17 at 15:30
  • @gre_gor I switched back to ESP8266WebServer.h however I cannot pass ArduinoJson.h's jsonObject to server.send(...) arduino.stackexchange.com/q/46961/27363 – Ciasto piekarz Nov 23 '17 at 16:24
