Retrive Retrieve value from thinkspeakThingSpeak using ESP8266 with Arduino setup

I just started learning esp8266ESP8266 and in my first project I am successfully able to send data to thinkspeakThingSpeak.com using esp8266ESP8266 with following code:

uploadData() {
  String apiKey = "ESDS8678890SDDS";
  String myData = "45.5"; // example of data to send
  if (espClient.connect(server,80)) { 
    String postStr = apiKey; 
    postStr +="&field1=";
    postStr += String(myData);
    postStr += "\r\n\r\n";
 
    espClient.print("POST /update HTTP/1.1\n");
    espClient.print("Host: api.thingspeak.com\n");
    espClient.print("Connection: close\n");
    espClient.print("X-THINGSPEAKAPIKEY: "+apiKey+"\n");
    espClient.print("Content-Type: application/x-www-form-urlencoded\n");
    espClient.print("Content-Length: ");
    espClient.print(postStr.length());
    espClient.print("\n\n");
    espClient.print(postStr);
    Serial.print(postStr);
    Serial.print("My Data: ");
    Serial.print(myData);
    Serial.print("\n");
  }
  espClient.stop();
}

But I have no idea how to retrieve data from thinkspeakThingSpeak using ESP8266.

// Using XXXXX here as my channel is private
GET https://api.thingspeak.com/channels/XXXXXX/fields/1.json?results=2

I think I have to use the above GET string to get the fields data. But I don't know how to create the request string.

Help would be appreciated. Thanks

Thanks.
