WiFiServer server(80);

void setup() {
  // 初始化序列埠
  Serial.begin(9600);
  Serial.println("Attempting to connect to WPA network...");
  Serial.print("SSID: ");
  Serial.println(ssid);

  if ( status != WL_CONNECTED) { 
    Serial.println("Couldn't get a wifi connection");
    while(true);
  } 
  else {
    server.begin();
  }
}

void loop() {
  // 監聽是否有用戶端傳送請求
  WiFiClient client = server.available();
  if (client == true) {
