This article mainly explains "how to scan code and even wifi in Mini Program", interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Next, let the editor take you to learn "how to scan code with wifi on Mini Program".
Mini Program disadvantages: android6 version ios11 version
Code:
/ / pages/wifi/wifi.js
Page ({
Data: {
StartError:'', / / initialize error message
WifiListError: false, / / wifi list error display switch
WifiListErrorInfo:'', / / wifi list error details
System:'', / / version number
Platform:'', / / system android
Ssid: 'wifi account', / / wifi account (required)
Pass: 'wifi password', / / Wireless network password (required)
Bssid:'', / / device number is obtained automatically
EndError:''/ / the last hint to connect
}
OnLoad: function () {
Var _ this = this
/ / check the phone model
Wx.getSystemInfo ({
Success: function (res) {
Var system =''
If (res.platform = = 'android') system = parseInt (res.system.substr (8))
If (res.platform = = 'ios') system = parseInt (res.system.substr (4))
If (res.platform = = 'android' & & system
< 6) { _this.setData({ startError: '手机版本暂时不支持' }); return } if (res.platform == 'ios' && system < 11) { _this.setData({ startError: '手机版本暂时不支持' }); return } _this.setData({ platform: res.platform }); //初始化 Wi-Fi 模块 _this.startWifi(_this); } }) },//初始化 Wi-Fi 模块。 startWifi: function (_this) { wx.startWifi({ success: function () { _this.getList(_this); }, fail: function (res) { _this.setData({ startError: res.errMsg }); } }) }, getList: function (_this) { //安卓执行方法 if (_this.data.platform == 'android') { //请求获取 Wi-Fi 列表 wx.getWifiList({ success: function (res) { //安卓执行方法 _this.AndroidList(_this); }, fail: function (res) { _this.setData({ wifiListError: true }); _this.setData({ wifiListErrorInfo: res.errMsg }); } }) } //IOS执行方法 if (_this.data.platform == 'ios') { _this.IosList(_this); } }, AndroidList: function (_this) { //监听获取到 Wi-Fi 列表数据 wx.onGetWifiList(function (res) { //获取列表 if (res.wifiList.length) { // _this.setData({ // wifiList: res.wifiList // }); //循环找出信号最好的那一个(wifi存在多个) var ssid = _this.data.ssid; var signalStrength = 0; var bssid = ''; for (var i = 0; i < res.wifiList.length; i++) { if (res.wifiList[i]['SSID'] == ssid && res.wifiList[i]['signalStrength'] >SignalStrength) {
Bssid = res.wifiList [I] ['BSSID']
SignalStrength = res.wifiList [I] ['signalStrength']
}
}
If (! signalStrength) {
_ this.setData ({wifiListError: true})
_ this.setData ({wifiListErrorInfo: 'the set wifi'} was not found)
Return
}
_ this.setData ({bssid: bssid})
/ / execute the connection method
/ / Connect to wifi
_ this.Connected (_ this)
} else {
_ this.setData ({wifiListError: true})
_ this.setData ({wifiListErrorInfo: 'the set wifi'} was not found)
