Всем привет! Кручу свой маленький проектик с веб сервером-клиентом. Поставил себе Postman, чтобы видеть, что отправляем и что получаем от сервера. Написал по примеру WebClient, запускаю, данные типа отправляются, а в ответ тишина... В чем причина не пойму, Postman показывает что на запрос Get сервер отдает информацию, а метод client.available() - молчит... Мой код: Код (C++): #include <SPI.h> #include <Ethernet2.h> // assign a MAC address for the ethernet controller. // fill in your address here: byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; // fill in an available IP address on your network here, // for manual configuration: IPAddress ip(192, 10, 10, 5); // fill in your Domain Name Server address here: IPAddress myDns(192, 10, 10, 1); // initialize the library instance: EthernetClient client; char server[] = "sss.ru"; unsigned long lastConnectionTime = 0; // last time you connected to the server, in milliseconds const unsigned long postingInterval = 5000L; // delay between updates, in milliseconds // the "L" is needed to use long type numbers void setup() { // start serial port: Serial.begin(9600); while (!Serial) { ; // wait for serial port to connect. Needed for Leonardo only } // give the ethernet module time to boot up: delay(1000); // start the Ethernet connection using a fixed IP address and DNS server: Ethernet.begin(mac, ip, myDns); // print the Ethernet board/shield's IP address: Serial.print("My IP address: "); Serial.println(Ethernet.localIP()); } unsigned long byteCount = 0; void loop() { if (client.available()) { Serial.println("Data Receive"); } if (millis() - lastConnectionTime > postingInterval) { httpRequest(); lastConnectionTime = millis(); } } // this method makes a HTTP connection to the server: void httpRequest() { // close any connection before send a new request. // This will free the socket on the WiFi shield client.stop(); // if there's a successful connection: if (client.connect(server, 80)) { Serial.println("connecting..."); // send the HTTP PUT request: client.println("GET /getinfo HTTP/1.1"); client.println("Host: sss.ru"); client.println("User-Agent: arduino-ethernet"); client.println("Connection: close"); client.println(); Serial.println("Send request OK"); // note the time that the connection was made: lastConnectionTime = millis(); } else { // if you couldn't make a connection: Serial.println("connection failed"); } } А вот ответ через Postman HTML: GET http://sss.ru/getinfo 200 51 ms Network Request Headers User-Agent: PostmanRuntime/7.28.3 Accept: */* Postman-Token: ac9b6e50-b24f-4df3-87dd-5f2f488af7e5 Host: sss.ru Accept-Encoding: gzip, deflate, br Connection: keep-alive Response Headers Date: Mon, 16 Aug 2021 18:27:45 GMT Server: Apache/2.4.34 (Win64) OpenSSL/1.0.2o Content-Length: 4 Keep-Alive: timeout=5, max=100 Connection: Keep-Alive Response Body used
