Code: Select all#include <ESP8266WiFi.h>
#include <ESP8266WebServer.h>

const char* ssid = "Connectify-cat";
const char* password = "12345678";

const char* newssid = "Esp-coba";

const char* host = "data.sparkfun.com";

ESP8266WebServer server(80);

int count = 0;

void setup(void){
  Serial.begin(115200);
  Serial.println("");

  // set both access point and station
  WiFi.mode(WIFI_AP_STA);
 
  WiFi.softAP(newssid, newpassword);

  Serial.print(newssid);
  Serial.print(" server ip: ");
  Serial.println(WiFi.softAPIP());

  server.on("/", handleRoot); 
  server.onNotFound(handleNotFound); 
  server.begin();
  Serial.println("HTTP server started");

  if (strcmp (WiFi.SSID(),ssid) != 0) {
      Serial.print("Connecting to ");
      Serial.println(ssid);
      WiFi.begin(ssid, password);
  }

  while (WiFi.status() != WL_CONNECTED) {
    yield();
  }

  Serial.print("Connected to: ");
  Serial.print(WiFi.SSID());
  Serial.print(", IP address: ");
  Serial.println(WiFi.localIP());
}
 
void loop(void){
  server.handleClient();
}

void handleRoot() {
  Serial.print("handleRoot: ");
  Serial.println(count);
  String s = "request count: ";
  s += ++count;
  server.send(200, "text/plain", s);
}

void handleNotFound() {
  Serial.print("proxy request to ");
  Serial.println(host);
 
  count++;

  WiFiClient client;
  while (!!!client.connect(host, 80)) {
    Serial.println("connection failed, retrying...");
  }

  Serial.print("Requesting uri: ");
  String requestUri = server.uri();

  // TODO: an easier way to get the request url?
  if (server.args() > 0) {
     requestUri += "?";
     for (int i=0; i<server.args(); i++) {
        requestUri += server.argName(i);
        requestUri += "=";
