功夫不负有心人，经过多日苦心摸索，终于攻克网页端控制LED的亮灭。

首先编写以下代码：

from machine import Pinimport networkimport socketimport time
led = Pin(2,Pin.OUT)
ssid = "iPhone (50)"password = "qq7895123"
def wifi_connect():    global wlan    wlan=network.WLAN(network.STA_IF)    wlan.active(True)        if not wlan.isconnected():        print("connecting to network ......")        wlan.connect(ssid,password)                while not wlan.isconnected():            led.value(1)            time.sleep_ms(250)            led.value(0)            time.sleep_ms(250)                    led.value(0)        return False            else:        led.value(0)        print("network information：",wlan.ifconfig())        return True    def web_page():    html="""        content="width=device-width,initial-scale=1">

if __name__=="__main__":    if wifi_connect():        s=socket.socket(socket.AF_INET,socket.SOCK_STREAM)        s.bind(('',80))        s.listen(5)                while True:            conn,addr = s.accept()            print('Got a connection from %s' % str(addr))                        request = conn.recv(1024)            request = str(request)            print('Content = %s'% request)                        led_on = request.find('/?led=on')            led_off= request.find('/?led=off')                        if led_on ==6:                print('LED ON')                led.value(1)            if led_off ==6:                print('LED OFF')                led.value(0)                            response = web_page()            conn.send('HTTP/1.1 200 OK\n')            conn.send('Content-Type:text/html\n')            conn.send('Connection:close\n\n')            conn.send('HTTP/1.1 200 OK\n')            conn.sendall(response)            conn.close()
