ESP32如何使用http.addHeader()添加主机标头

#include <WiFi.h>
#include <HTTPClient.h>

const char* ssid = "your_SSID";
const char* password = "your_PASSWORD";

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

  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to WiFi...");
  }
  Serial.println("Connected to WiFi");

  HTTPClient http;
  http.begin("http://example.com"); // 设置要访问的URL

  // 添加主机标头
  http.addHeader("Host", "example.com");

  int httpCode = http.GET();
  if (httpCode > 0) {
    String payload = http.getString();
    Serial.println(payload);
  } else {
    Serial.println("Error on HTTP request");
  }

  http.end();
}

void loop() {
  // 无需在循环中执行任何操作
}
