如何查看arduino发送到php表单的HTTP POST值

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

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

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

void loop() {
  if (WiFi.status() == WL_CONNECTED) {
    HTTPClient http;
    http.begin("http://your_php_form_url");  // 替换为你的PHP表单URL
    http.addHeader("Content-Type", "application/x-www-form-urlencoded");

    String postData = "param1=value1&param2=value2";  // 替换为你的POST参数和数值
    int httpResponseCode = http.POST(postData);

    if (httpResponseCode > 0) {
      String response = http.getString();
      Serial.println(httpResponseCode);
      Serial.println(response);
    } else {
      Serial.print("Error code: ");
      Serial.println(httpResponseCode);
    }

    http.end();
  }

  delay(5000);  // 每隔5秒发送一次POST请求
}

<?php
$param1 = $_POST['param1'];
$param2 = $_POST['param2'];

echo "Received POST values: param1 = $param1, param2 = $param2";
?>
