esp32模块像客户端发送数据与TCP/IP数据传输实现代码

你好，以下是回答：

ESP32模块像客户端发送数据的代码示例：

#include <WiFi.h>

const char* ssid = "your_SSID";
const char* password = "your_PASSWORD";
const char* host = "your_server_address";
const int port = 80;

void setup() {
  Serial.begin(115200);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(100);
    Serial.println("Connecting to WiFi...");
  }
  Serial.println("Connected to WiFi");
}

void loop() {
  WiFiClient client;
  if (client.connect(host, port)) {
    Serial.println("Connected to server");
    client.println("GET / HTTP/1.1");
    client.println("Host: your_server_address");
    client.println("Connection: close");
    client.println();
    while (client.connected()) {
      String line = client.readStringUntil('\n');
      Serial.println(line);
    }
    client.stop();
  } else {
    Serial.println("Failed to connect to server");
  }
  delay(500);
}

TCP/IP数据传输的实现代码示例：

#include <WiFi.h>

const char* ssid = "your_SSID";
const char* password = "your_PASSWORD";
const char* host = "your_server_address";
const int port = 80;

void setup() {
  Serial.begin(115200);
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(100);
    Serial.println("Connecting to WiFi...");
  }
  Serial.println("Connected to WiFi");
}

void loop() {
  WiFiClient client;
  if (client.connect(host, port)) {
    Serial.println("Connected to server");
    client.write("Hello, server!");
    while (client.connected()) {
      if (client.available()) {
        char c = client.read();
        Serial.print(c);
      }
    }
    client.stop();
  } else {
    Serial.println("Failed to connect to server");
  }
  delay(500);
}

希望能够帮到你！
