esp8266获取当前时间通过串口打印yyyymmdd hhmmss的格式给我代码

以下是ESP8266获取当前时间并通过串口打印“yyyy:mm:dd hh:mm:ss”的代码：

#include <ESP8266WiFi.h>
#include <Wire.h>
#include <TimeLib.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!");

  configTime(0, 0, "pool.ntp.org"); //获取网络时间
  while (!time(nullptr)) {
    delay(1000);
    Serial.println("Waiting for NTP time sync...");
  }
}

void loop() {
  time_t now = time(nullptr);
  if (now != 0) {
    Serial.println("Current time is: ");
    Serial.print(year(now));
    Serial.print(":");
    Serial.print(month(now));
    Serial.print(":");
    Serial.print(day(now));
    Serial.print(" ");
    Serial.print(hour(now));
    Serial.print(":");
    Serial.print(minute(now));
    Serial.print(":");
    Serial.println(second(now));
  } else {
    Serial.println("Failed to get NTP time");
  }
  delay(1000);
}

需要先连接到WiFi并获取网络时间，然后在loop循环中获取当前时间并通过串口打印。
