首先我们要知道这个是怎么设置的。

搜到了视频教程

知道考勤设置的是SSID以及MAC地址所以需要知道公司Wi-Fi路由器背面的MAC地址是多少，~~你们可以半夜偷偷去撬开老板存放路由器的保险柜~~，我就不用了。

知道他们怎么设置这个考勤的，那么做一个一模一样的Wi-Fi应该可以实现上下床打卡了。

首先我们找一个可以开启AP(Access Points)的东西，越小越好，像这样。

还要可以实时配置，防止老板突然换路由器，这里写一个简单网站前端。

板子刷个MicroPython环境，可以很简单的写个后端，当然需要先默认开启Wi-Fi连上去你才打得开这个网站。

boot.py

import time

import network
import ujson


def check_file(filename):
    try:
        with open(filename, "r") as f:
            return True
    except Exception as e:
        return False

def wifi_ap(tssid, tpassword, tmac):
    ap = network.WLAN(network.AP_IF)
    ap.active(True)
    ap.config(mac=bytearray(bytes.fromhex(tmac.replace(':', ''))))
    ap.config(ssid=tssid, password=tpassword)
    ap.config(authmode=4)

def wifi_def_ap():
    ap = network.WLAN(network.AP_IF)
    ap.config(ssid='您配吗')
    ap.active(True)


try:
    if check_file("wifi_config_mac.json"):
        with open('wifi_config_mac.json', 'r+') as f:  # 尝试打开wifi_config文件
            config = ujson.loads(f.read())  # 获取wifi_config的信息
        wifi_ap(config['ssid'], config['password'], config['macAddr'])  # 进行WiFi连接
    else:
        wifi_def_ap()
except Exception as e:
    print("Error:", e)
    wifi_def_ap()

后端这里有个简单的库，安装非常简单
https://microdot.readthedocs.io/en/latest/intro.html#micropython-installation

main.py

import time
import network
import ujson

from microdot import Microdot, send_file

app = Microdot()

sta_if = network.WLAN(network.STA_IF)


def parse_string_params(input_string):
    param_list = input_string.split('&')
    params = {}
    for param in param_list:
        key, value = param.split('=')
        params[key] = value

    return params


def connect_wifi(wifi_ssid, wifi_password):
    # 连接 WiFi
    sta_if.active(True)
    sta_if.connect(wifi_ssid, wifi_password)
    # 等待连接成功
    count = 0
    while not sta_if.isconnected():
        count += 1
        print('第' + str(count) + 'ci')
        time.sleep(1)
        if count > 10:  # 如果检测到大于10次连不上（10秒后还没有联网）关闭WiFi并返回
            sta_if.active(False)
            return False
    if sta_if.isconnected():
        print('network config:', sta_if.ifconfig())
        print('')
        return True
    else:
        print('failed to connect to network')
        return False


def check_file(filename):
    try:
        with open(filename, "r") as f:
            return True
    except Exception as e:
        return False


@app.get('/')
def hello(request):
    return send_file('root.html')


@app.post('/find')
def find(request):
    if check_file("wifi_config_mac.json"):
        with open('wifi_config_mac.json', 'r+') as f:
            config = ujson.loads(f.read())
            return config
    return {"ssid": "demo", "password": "12", "macAddr": "2333"}


@app.post('/post')
def post(request):
    body = request.body
    params = parse_string_params(body.decode('utf-8'))
    config = dict(ssid=params["ssid"], password=params["password"], macAddr=params['macAddr'])
    with open('wifi_config_mac.json', 'w+') as f:
        f.write(ujson.dumps(config))
    return {"result": "配上了！"}
    #if connect_wifi(params["ssid"], params["password"]):
    #     config = dict(ssid=params["ssid"], password=params["password"], macAddr=params['macAddr'])
    #     with open('wifi_config_mac.json', 'w+') as f:
    #         f.write(ujson.dumps(config))
    #     return {"result": "配上了！"}
    # else:
    #     return {"result": "你不配！账号密码都搞错了"}

app.run(port=80)
