uni app实现WIFI功能 一.前言二.使用 uni-WIFI三.使用h5+ api

一.前言

最近需要在uniapp上实现WiFi功能,将个人的研究结果记录如下(都只支持安卓APP)

使用 uni-WIFI使用h5+ api 二.使用 uni-WIFI

完整代码地址暂未上传

如果遇到打包错误可尝试修改 在这里插入图片描述 在这里插入图片描述 将 minSdkVersion 改为21

如果是自定义基座，需要具备下面的权限

"", "", "", "" 判断是否有定位权限(因为使用WiFi模块需要使用定位,如果定位没有打开初始化WiFi就会失败) async isPermission() { const res = await requestAndroidPermission('android.permission.ACCESS_FINE_LOCATION') // 当res为1表示有这个权限 if (res === 1) { // 调用WiFi初始化 this.wifiInit() } else { //没有权限执行的 ... } }

权限查询的函数,基于 https://ext.dcloud.net.cn/plugin?id=594

/** * Android权限查询 * @param permissionID * android.permission.ACCESS_FINE_LOCATION 位置权限 * android.permission.ACCESS_COARSE_LOCATION 模糊位置权限(蓝牙\ble依赖) * android.permission.CAMERA 摄像头权限 * android.permission.READ_EXTERNAL_STORAGE 外部存储(含相册)读取权限 * android.permission.WRITE_EXTERNAL_STORAGE 外部存储(含相册)写入权限 * android.permission.RECORD_AUDIO 麦克风权限 * android.permission.READ_CONTACTS 通讯录读取权限 * android.permission.WRITE_CONTACTS 通讯录写入权限 * android.permission.READ_CALENDAR 日历读取权限 * android.permission.WRITE_CALENDAR 日历写入权限 * android.permission.READ_SMS 短信读取权限 * android.permission.SEND_SMS 短信发送权限 * android.permission.RECEIVE_SMS 接收新短信权限 * android.permission.READ_PHONE_STATE 获取手机识别码等信息的权限 * android.permission.CALL_PHONE 拨打电话权限 * android.permission.READ_CALL_LOG 获取通话记录权限 * @return {Promise} */ export function requestAndroidPermission(permissionID) { return new Promise((resolve, reject) => { plus.android.requestPermissions( [permissionID], // 理论上支持多个权限同时查询，但实际上本函数封装只处理了一个权限的情况。有需要的可自行扩展封装 function (resultObj) { let result = 0; for (let i = 0; i const deniedPresentPermission = resultObj.deniedPresent[i]; console.log('拒绝本次申请的权限：' + deniedPresentPermission); result = 0 } for (let i = 0; i // gotoAppPermissionSetting() // } }, function (error) { console.log('申请权限错误：' + error.code + " = " + error.message); resolve({ code: error.code, message: error.message }); } ); }); } /** * 跳转到设置权限页面 */ export function gotoAppPermissionSetting() { const Intent = plus.android.importClass("android.content.Intent"); const Settings = plus.android.importClass("android.provider.Settings"); const Uri = plus.android.importClass("android.net.Uri"); const mainActivity = plus.android.runtimeMainActivity(); const intent = new Intent(); intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS); const uri = Uri.fromParts("package", mainActivity.getPackageName(), null); intent.setData(uri); mainActivity.startActivity(intent); }

2.如果有权限开始初始化WiFi

// 初始化 wifiInit() { // #ifdef APP-PLUS uni.startWifi({ fail: (e) => { console.log(e) } }) // 监听获取到wifi列表 uni.onGetWifiList(this.onGetWifiListFun) // 获取WiFi列表 this.getWifiConnectInfo() // #endif }

3.获取当前连接的WiFi信息

getWifiConnectInfo() { // #ifdef APP-PLUS uni.getConnectedWifi({ partialInfo: true, success: ({wifi}) => { console.log(wifi) this.connectWifi = wifi.SSID return wifi }, complete: () => { //获取WiFi列表 this.getWifiListFun() } }) // #endif }

4.获取wifi列表

getWifiListFun() { // #ifdef APP-PLUS uni.getWifiList({ complete: () => { // 移除监听函数 uni.offGetWifiList(this.onGetWifiListFun) // 获取当前连接的WiFi信息 } }) // #endif }

监听获取到的WiFi列表函数

onGetWifiListFun(info) { this.wifiList = [] let wifiList = [] // 过滤掉没有SSID的 还有我个人对信号的处理,用来渲染对应的样式的 wifiList = info.wifiList.filter(item => { if (item.signalStrength >= -55) { item['signalDefine'] = [true, true, true] } else if (item.signalStrength >= -66) { item['signalDefine'] = [false, true, true] } else if (item.signalStrength >= -88) { item['signalDefine'] = [false, false, true] } else if (item.signalStrength >= -100) { item['signalDefine'] = [false, false, false] } return item.SSID }) // 按信号强度排序 wifiList = wifiList.sort((a, b) => { return b.signalStrength - a.signalStrength }) // 取当前连接的WiFi的信号 const connectResIndex = wifiList.findIndex(item => item.SSID === this.connectWifi) const connectRes = wifiList[connectResIndex] if (connectRes) { this.connectWifiSignal = connectRes['signalDefine'] this.connectRes = connectRes } wifiList.splice(connectResIndex, 1) this.wifiList = wifiList // 获取成功,关闭loading uni.hideLoading(); console.log('wifiList', wifiList) console.log('wifiList', this.wifiList) // console.log(info) },

5.连接WiFi

uni.connectWifi({ SSID: wifiInfo.SSID, BSSID: wifiInfo.BSSID, //WiFi的密码 password: this.pwd, partialInfo: true, maunal: false, fail: (e) => { console.log(e) let msg switch (e.errCode) { case 12002: { msg = 'WI-FI密码错误!' break } case 12013: { msg = 'Wi-Fi 配置过期，建议忘记 Wi-Fi 后重试!' break } case 12005: { msg = '未打开 Wi-Fi!' break } default: { msg = e.errMsg } } uni.showToast({ icon: 'none', title: msg }) }, success: (info) => { if (info.errCode === 0) { uni.showToast({ icon: 'none', title: `${info.wifi.SSID}连接成功!` }) //连接成功后的处理 ... } } }) 三.使用h5+ api

这里没有实现监听到WiFi是否连接成功,但我找了下网上资料,可以监听广播的方式,我试了几种没有找到合适的,希望大家能补充下.

扫描WiFi {{ item.name }} export default { data() { return { wifiManager: null, WifiConfiguration: null, wifis: null, nowWifiInfo: null, wifiArray: [], ArrayList: null }; }, // #ifdef APP-PLUS methods: { // 初始化WiFi initWifi() { const MainActivity = plus.android.runtimeMainActivity() const Context = plus.android.importClass("android.content.Context");
