ESP8266 Simple Example Sketch?

[beicnet]

Hi there,

Can someone give me for this library the simplest GET example sketch?

Thank you!

Kind regards, Viktor

Unfortunately this issue #111 [minimal example for ESP32] was locked. I could find no solution till now and opend a thread at https://forum.arduino.cc/t/using-arduinohttpclient-lib-with-esp32/902455

I tried this ...

#include <ArduinoHttpClient.h>

#include <WiFi.h>
#include <WiFiMulti.h>
WiFiMulti wifiMulti;

WiFiClient wifi;
HttpClient http(wifi,"arduino.cc",80);

void setup() {
  Serial.begin(115200);
  wifiMulti.addAP("your-ssid","your-pw");
  
  // attempt to connect to WiFi
  Serial.print("Connecting to Wifi ... ");
  while (wifiMulti.run() != WL_CONNECTED) {
    // unsuccessful, retry in 4 seconds
    Serial.print("failed ... ");
    delay(4000);
    Serial.print("retrying ... ");
  }
  Serial.println("WiFi connected");
}

void loop() {
  Serial.println("making GET request");
  http.get("/asciilogo.txt");

  // read the status code and body of the response
  int statusCode = http.responseStatusCode();
  String response = http.responseBody();

  Serial.print("Status code: ");
  Serial.println(statusCode);
  Serial.print("Response: ");
  Serial.println(response);
  Serial.println("Wait five seconds");
  delay(5000);
}

but it stalls after

Connecting to Wifi ... WiFi connected
making GET request
Status code: -3
Response: 
Wait five seconds

Is the Arduino - WiFiClient used in the ArduinoHttpClient lib not compatible with the ESP32 implementaton (e.g. used in https://github.com/espressif/arduino-esp32/blob/master/libraries/WiFi/examples/WiFiClient/WiFiClient.ino)?

WiFiClient client; is called in loop() in the ESP32 / espressif example while WiFiClient wifi; is called already before setup() in https://github.com/arduino-libraries/ArduinoHttpClient/blob/master/examples/SimpleGet/SimpleGet.ino ?? Is it perhaps the same syntax but different functions?

How can I get working the ArduinoHttpClient library with an ESP32? Any chance?
