公司想建个网站怎么弄网站如何优化流程

模拟的是蓝牙设备签到/签出：

1. 获取指定蓝牙设备
2. 蓝牙初始搜索次数限制，超过限制就停止搜索
3. 蓝牙连接失败次数限制，超过限制标识蓝牙连接失败（离开蓝牙范围或其他原因）
4. 自动重连指定蓝牙

const device = ref<any>(null); // 设备信息
const crpBlueList = ref<any[]>([]); // 扫描到的蓝牙信息列表
const linkStatus = ref(false); // 连接状态
const searchTimes = ref(0); // 搜索次数
const searchLimit = 5; // 搜索次数限制
const linkTimes = ref(0); // 扫描次数
const failTimes = ref(0); // 失败次数
const failLimit = 5; // 失败次数限制
const blueName = 'zo-crp'; // 指定蓝牙设备的名称前缀
let isSignIn = false; // 是否签到
// 签到
const signIn = () => {searchTimes.value = 0;uni.showLoading({title: '蓝牙搜索中...',mask: true});openBluetoothAdapter(() => {startBluetoothDeviceDiscovery();});
};
// 签出
const logout = () => {closeBlueTooth(device.value, () => {isSignIn = false;device.value = null;linkStatus.value = false;searchTimes.value = 0;linkTimes.value = 0;failTimes.value = 0;crpBlueList.value = [];uni.showToast({title: '已签出'});});
};
// 初始化蓝牙
const openBluetoothAdapter = (callback: Function) => {uni.openBluetoothAdapter({//打开蓝牙适配器接口success: (res) => {//已打开callback();},fail: (err) => {uni.hideLoading();uni.showModal({title: '',content: '该操作需要蓝牙支持！请打开蓝牙',showCancel: false,success: (res) => {if (res.confirm) {// #ifdef APPlet main = plus.android.runtimeMainActivity();let Intent = plus.android.importClass('android.content.Intent');let mIntent = new Intent('android.settings.BLUETOOTH_SETTINGS');main.startActivity(mIntent);// #endif} else {navigateBack();}},complete: () => {}});}});
