/* * This sketch demonstrates how to set up a simple HTTP-like server. * The server will set a GPIO pin depending on the request * http://server_ip/gpio/0 will set the GPIO2 low, * http://server_ip/gpio/1 will set the GPIO2 high * server_ip is the IP address of the ESP8266 module, will be * printed to Serial when the module is connected. */ #include #include #include #include const char* ssid = "youhousenetwor";//"Enter Your WiFi Name " const char* password = "yourpassword";//"Enter Your WiFi Password" // Create an instance of the server // specify the port to listen on as an argument WiFiServer server(80); void setup() { Serial.begin(115200); delay(10); // prepare GPIO2 pinMode(13, OUTPUT); digitalWrite(13, 0); // Connect to WiFi network Serial.println(); Serial.println(); Serial.print("Connecting to "); Serial.println(ssid); WiFi.begin(ssid, password); while (WiFi.status() != WL_CONNECTED) { delay(500); Serial.print("."); } Serial.println(""); Serial.println("WiFi connected"); // Start the server server.begin(); Serial.println("Server started"); // Print the IP address Serial.println(WiFi.localIP()); } void loop() { // Check if a client has connected WiFiClient client = server.available(); if (!client) { return; } // Wait until the client sends some data Serial.println("new client"); while(!client.available()){ delay(1); } client.println("HTTP/1.1 200 OK"); client.println("Content-Type: text/html"); client.println(""); client.println(""); client.println(""); client.println(""); // Read the first line of the request String req = client.readStringUntil('\r'); Serial.println(req); client.flush(); // Match the request int val; if (req.indexOf("/gpio/0") != -1) val = 0; else if (req.indexOf("/gpio/1") != -1) val = 1; else { Serial.println("invalid request"); client.stop(); return; } // Set GPIO2 according to the request digitalWrite(13, val); client.flush(); // Prepare the response String s = "HTTP/1.1 200 OK\r\nContent-Type: text/html\r\n\r\n\r\n\r\nGPIO is now "; s += (val)?"high":"low"; s += "\n"; // Send the response to the client client.print(s); delay(1); Serial.println("Client disonnected"); // The client will actually be disconnected // when the function returns and 'client' object is detroyed }
