精确定位使用:
<!-- 精确定位 --> <template> <view>{{ positionInfo }}</view> </template> <script> import '@/utils/geolocation.min.js'; export default { data() { return { positionInfo: '' }; }, onl oad(options) { this._initLocation(); }, methods: { _initLocation() { if (origin.indexOf('https') === -1) { uni.showToast({ title: '请在https环境中使用' }); return; } if (!navigator || !navigator.geolocation) { uni.showToast({ title: '地理位置服务不可用' }); return; } uni.showLoading({ title: '定位中...', mask: true }); const options = { enableHighAccuracy: true, timeout: 5000, maximumAge: 0 }; /** err 说明 code 1 表示用户拒绝授权 code 3 未获取到地址信息,可能是设备没有开启定位服务或者系统没有给浏览器定位权限 **/ navigator.geolocation.getCurrentPosition( (position) => { const lat = position.coords.latitude, lng = position.coords.longitude, geo = new qq.maps.Geolocation('地图api key', '获取位置信息'); geo.getLocation(this.getLocationSuccess, this.getLocationErr, options); }, (err) => { if (err.code === 1) { uni.showModal({ title: '获取定位权限失败', content: '你拒绝了位置授权服务。请允许当前页面获取定位授权,后刷新页面。' }); } else { uni.showModal({ title: '获取定位权限失败', content: '请确定手机定位已打开,并且当前浏览器允许获取定位,都开启后请刷新页面。' }); } uni.hideLoading(); } ); }, getLocationSuccess(position) { uni.showToast({ title: '定位成功!', duration: 1000 }); this.positionInfo = position; uni.hideLoading(); }, getLocationErr() { uni.showToast({ title: '获取位置失败!', duration: 2000 }); uni.hideLoading(); } } }; </script>
效果:
ip定位使用:
<!-- IP定位 --> <template> <view>{{ positionInfo }}</view> </template> <script> import '@/utils/geolocation.min.js'; export default { data() { return { positionInfo: '' }; }, onl oad(options) { this._initLocation(); }, methods: { _initLocation() { if (origin.indexOf('https') === -1) { uni.showToast({ title: '请在https环境中使用' }); return; } if (!navigator || !navigator.geolocation) { uni.showToast({ title: '地理位置服务不可用', duration: 2000 }); return; } const options = { enableHighAccuracy: true, timeout: 5000, maximumAge: 0 }; uni.showLoading({ title: '定位中...', mask: true }); /** err 说明 code 1 表示用户拒绝授权 code 3 未获取到地址信息,可能是设备没有开启定位服务或者系统没有给浏览器定位权限 **/ navigator.geolocation.getCurrentPosition( (position) => { const lat = position.coords.latitude, lng = position.coords.longitude, geo = new qq.maps.Geolocation('QAWBZ-S2MWR-U5OWI-WZBUC-UXDSZ-AAFRJ', '获取位置信息'); geo.getIpLocation(this.getIpLocationSuccess, this.getIpLocationErr, options); }, (err) => { if (err.code === 1) { uni.showModal({ title: '获取定位权限失败', content: '你拒绝了位置授权服务。请允许当前页面获取定位授权,后刷新页面。' }); } else { uni.showModal({ title: '获取定位权限失败', content: '请确定手机定位已打开,并且当前浏览器允许获取定位,都开启后请刷新页面。' }); } uni.hideLoading(); } ); }, getIpLocationSuccess(position) { uni.showToast({ title: '定位成功!', duration: 1000 }); this.positionInfo = position; uni.hideLoading(); }, getIpLocationErr() { uni.showToast({ title: '获取位置失败!', duration: 2000 }); uni.hideLoading(); } } }; </script>
效果如上一样,只是区别于当前是通过ip定位的。
实时监听当前位置:
<!-- 监听位置 --> <template> <view class="watch-position"> <view class="watch-position-btn"> <view class="btn" @click="watchPosition">开启监听</view> <view class="btn" @click="clearWatch">关闭监听</view> </view> <view class="watch-position-info" v-if="positionInfo.length"> <view class="watch-position-info-title">位置信息:</view> <view class="watch-position-info-list"> <view class="watch-position-info-list-item" v-for="(item, index) in positionInfo" :key="index"> {{ `第${index + 1}次:` }}<br />{{ JSON.stringify(item) }} </view> </view> </view> </view> </template> <script> import '@/utils/geolocation.min.js'; export default { data() { return { positionInfo: [], geo: null, isWatch: false }; }, onl oad() { this._initPosition(); }, methods: { _initPosition() { if (origin.indexOf('https') === -1) { uni.showToast({ title: '请在https环境中使用' }); return; } if (!navigator || !navigator.geolocation) { uni.showToast({ title: '地理位置服务不可用', duration: 2000 }); return; } uni.showLoading({ title: '定位中...', mask: true }); /** err 说明 code 1 表示用户拒绝授权 code 3 未获取到地址信息,可能是设备没有开启定位服务或者系统没有给浏览器定位权限 **/ navigator.geolocation.getCurrentPosition( (position) => { const lat = position.coords.latitude, lng = position.coords.longitude, geo = new qq.maps.Geolocation('QAWBZ-S2MWR-U5OWI-WZBUC-UXDSZ-AAFRJ', '获取位置信息'); this.geo = geo; uni.hideLoading(); }, (err) => { if (err.code === 1) { uni.showModal({ title: '获取定位权限失败', content: '你拒绝了位置授权服务。请允许当前页面获取定位授权,后刷新页面。' }); } else { uni.showModal({ title: '获取定位权限失败', content: '请确定手机定位已打开,并且当前浏览器允许获取定位,都开启后请刷新页面。' }); } uni.hideLoading(); } ); }, watchPosition() { const options = { enableHighAccuracy: true, timeout: 5000, maximumAge: 0 }; if (this.isWatch) return uni.showToast({ title: '已开启持续监听,请勿重复开启' }); if (this.geo) { this.isWatch = true; this.geo.watchPosition(this.watchPositionSuccess, this.watchPositionErr, options); } else { uni.showModal({ title: '获取定位权限失败', content: '请确定手机定位已打开,并且当前浏览器允许获取定位,都开启后请刷新页面。' }); } }, watchPositionSuccess(position) { this.positionInfo.push(position); }, watchPositionErr() { uni.showToast({ title: '获取位置失败!' }); }, clearWatch() { if (!this.isWatch) return uni.showToast({ title: '已关闭持续监听,请勿重复关闭' }); this.isWatch = false; this.geo.clearWatch(); } } }; </script> <style lang="scss" scoped> .watch-position { min-height: 100vh; background-color: #ededed; &-info { padding: 30rpx; &-title { margin-bottom: 30rpx; } &-list { background: #fff; &-item { width: 100%; margin-bottom: 20rpx; word-break: break-all; } } } &-btn { margin: 0 auto 40rpx; text-align: center; padding-top: 40rpx; } } .btn { background-color: #4cd964; color: #ffffff; margin: 0 auto 30rpx; padding: 15rpx; border-radius: 10rpx; font-size: 26rpx; text-align: center; width: 40%; } </style>
效果:
注:使用浏览器定位域名必须是https访问
