Я делаю приложение которое посылает запросы на сервер, который работает с ESP32. Подключение по wifi типа точки доступа, я делаю GET запрос на IP, но не знаю как выдать ответ(данные с датчика).
На данный момент код вот такой, как мне послать данные в ответ на GET запрос?
#include <WiFi.h> #include <WiFiClient.h> #include <WebServer.h> #include "ArduinoJson.h" #include <WiFiAP.h> #define BMX055_DISABLE_BMM // Не использовать магнитометр. Курс будет ориентирован на начальное положение модуля #include <iarduino_Position_BMX055.h> // Подключаем библиотеку iarduino_Position_BMX055 для работы с Trema-модулем IMU 9 DOF. iarduino_Position_BMX055 sensor(BMX); #define LED_BUILTIN 2 // Set the GPIO pin where you connected your test LED or comment this line out if your dev board has a built-in LED // Set these to your desired credentials. const char *ssid = "yourAP"; const char *password = "yourPassword"; WiFiServer server(80); void setup() { pinMode(LED_BUILTIN, OUTPUT); Serial.begin(115200); sensor.begin(); Serial.println(); Serial.println("Configuring access point..."); // You can remove the password parameter if you want the AP to be open. WiFi.softAP(ssid, password); IPAddress myIP = WiFi.softAPIP(); Serial.print("AP IP address: "); Serial.println(myIP); server.begin(); Serial.println("Server started"); } String getQuat(){ sensor.read(); String res = String(sensor.q1) + String(sensor.q2) + String(sensor.q3) + String(sensor.q4); return res; } void loop() { DynamicJsonDocument doc(1024); WiFiClient client = server.available(); // listen for incoming clients if (client) { // if you get a client, Serial.println("New Client."); // print a message out the serial port String currentLine = ""; // make a String to hold incoming data from the client while (client.connected()) { // loop while the client's connected if (client.available()) { // if there's bytes to read from the client, char c = client.read(); // read a byte, then Serial.write(c); // print it out the serial monitor if (c == '\n') { // if the byte is a newline character // if the current line is blank, you got two newline characters in a row. // that's the end of the client HTTP request, so send a response: if (currentLine.length() == 0) { // HTTP headers always start with a response code (e.g. HTTP/1.1 200 OK) // and a content-type so the client knows what's coming, then a blank line: client.println("HTTP/1.1 200 OK"); client.println("Content-type:text/html"); client.println(); // the content of the HTTP response follows the header: client.print("Click <a href=\"/H\">here</a> to turn ON the LED.<br>"); client.print("Click <a href=\"/L\">here</a> to turn OFF the LED.<br>"); // The HTTP response ends with another blank line: //client.println(); // break out of the while loop: break; } else { // if you got a newline, then clear currentLine: currentLine = ""; } } else if (c != '\r') { // if you got anything else but a carriage return character, currentLine += c; // add it to the end of the currentLine } // Check to see if the client request was "GET /H" or "GET /L": doc["qX"] = sensor.q1; doc["qY"] = sensor.q2; doc["qZ"] = sensor.q3; doc["qW"] = sensor.q4; String outStr; serializeJson(doc, outStr); client.println(outStr); if (currentLine.endsWith("GET /H")) { digitalWrite(LED_BUILTIN, HIGH); // GET /H turns the LED on } if (currentLine.endsWith("GET /L")) { digitalWrite(LED_BUILTIN, LOW); // GET /L turns the LED off } } } // close the connection: client.stop(); Serial.println("Client Disconnected."); } }
