下面範例使用了Google Map GeoLocation Api對raspberry pi進行地理定位,
其中key可在https://console.developers.google.com申請,每日免費額度是2500(每100秒限制10000次)
/* npm i pi-wifi google-geolocation node main.js */ function geolocation(callback){ var geolocation = require ('google-geolocation') ({ key: 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' }); var piWifi = require('pi-wifi'); piWifi.scan(function(err, networks) { if (err) { return console.error(err.message); } //console.log(networks); var items=[]; for(i in networks){ items.push({ 'macAddress': networks[i].bssid, 'signalStrength': networks[i].signalLevel, }); } var params={ wifiAccessPoints: items, }; geolocation (params, (err, data) => { if (err) { return; } var result={ 'lat': data.location.lat, 'lng': data.location.lng, 'accuracy': data.accuracy, 'type': 'wifi', }; if(callback && typeof(callback) == "function") callback(result); }); }); } geolocation(function(location){ console.log(location); var url = "https://www.google.com.tw/maps/search/"+location.lat+","+location.lng; console.log(url); });
