I tried to do a Clock News Weather Scrolling Marquee with the esp8266. But when I upload the code it's got an error. Can you help me? Here's a part of the code:( under the MIT License (Copyright 2018 David Payne))

  void PiHoleClient::getPiHoleData(String server, int port) {

  errorMessage = "";
  String response = "";

  String apiGetData = "http://" + server + ":" + String(port) + "/admin/api.php?summary";
  Serial.println("Sending: " + apiGetData);
  HTTPClient http;  //Object of class HTTPClient
  http.begin(apiGetData);// get the result (**the error code**)
  int httpCode = http.GET();
  //Check the returning code
  if (httpCode > 0) {
    response = http.getString();
    http.end();   //Close connection
    if (httpCode != 200) {
      // Bad Response Code
      errorMessage = "Error response (" + String(httpCode) + "): " + response;
      Serial.println(errorMessage);
      return;  
    }

error: exit status 1 call to 'HTTPClient::begin' declared with attribute error: obsolete API, use ::begin(WiFiClient, url)

You need to also create a new instance of WiFiClient from WiFiClient.h, and pass that in to the begin:

#include <WiFiClient.h>

WiFiClient wifiClient;

void PiHoleClient::getPiHoleData(String server, int port) {

  errorMessage = "";
  String response = "";

  String apiGetData = "http://" + server + ":" + String(port) + "/admin/api.php?summary";
  Serial.println("Request: " + apiGetData);
  HTTPClient http;  //Object of class HTTPClient
  http.begin(wifiClient, apiGetData);// get the result (**the error code**)
  int httpCode = http.GET();
  //Check the returning code
  if (httpCode > 0) {
    response = http.getString();
    http.end();   //Close connection
    if (httpCode != 200) {
      // Bad Response Code
      errorMessage = "Error response (" + String(httpCode) + "): " + response;
      Serial.println(errorMessage);
      return;  
    }

I saw this post and have checked this, I updated the esp8266 core to v3.0.0 earlier this week and also found that marquee scroller doesn’t compile and gives the identical errors, I have reinstalled v2.7.4 and it compiled first time.
