微信小程序获取地理位置
小程序只支持获取当前位置的经纬度,并不能直接获取到地理名称,需要通过第三方来逆地址解析,这里我选择的是腾讯位置服务
在使用前需要去申请key,这里是地址:https://lbs.qq.com/console/mykey.html?console=mykey
下面上栗子:
<view class="hotcity-common thisCity">当前选择城市</view>
<view class="thisCityName">{{city}}</view>
var QQMapWX = require('../../utils/qqmap-wx-jssdk.js');
var qqmapsdk;
page({
data: {
city: "",
latitude: '',
longitude: '',
}
onLoad: function() {
qqmapsdk = new QQMapWX({
key: 'FD2BZ-R34KJ-4P4FW-KAW2S-ZASLV-GCFBR' //自己的key秘钥
});
this.getUserLocation();
},
getUserLocation: function() {
let vm = this;
wx.getSetting({
success: (res) => {
console.log("设置信息"+JSON.stringify(res))
if (res.authSetting['scope.userLocation'] != undefined && res.authSetting['scope.userLocation'] != true) {
wx.showModal({
title: '请求授权当前位置',
content: '需要获取您的地理位置,请确认授权',
success: function(res) {
if (res.cancel) {
wx.showToast({
title: '拒绝授权',
icon: 'none',
duration: 1000
})
} else if (res.confirm) {
wx.openSetting({
success: function(dataAu) {
if (dataAu.authSetting["scope.userLocation"] == true) {
wx.showToast({
title: '授权成功',
icon: 'success',
duration: 1000
})
//再次授权,调用wx.getLocation的API
vm.getLocation();
} else {
wx.showToast({
title: '授权失败',
icon: 'none',
duration: 1000
})
}
}
})
}
}
})
} else if (res.authSetting['scope.userLocation'] == undefined) {
//调用wx.getLocation的API
vm.getLocation();
} else {
//调用wx.getLocation的API
vm.getLocation();
}
}
})
},
// 微信获得经纬度
getLocation: function() {
let vm = this;
wx.getLocation({
type: 'wgs84',
success: function(res) {
console.log(JSON.stringify(res))
var latitude = res.latitude
var longitude = res.longitude
var speed = res.speed
var accuracy = res.accuracy;
vm.getLocal(latitude, longitude)
},
fail: function(res) {
console.log('fail' + JSON.stringify(res))
}
})
},
// 获取当前地理位置
getLocal: function(latitude, longitude) {
let vm = this;
qqmapsdk.reverseGeocoder({
location: {
latitude: latitude,
longitude: longitude
},
success: function(res) {
let province = res.result.ad_info.province
let city = res.result.ad_info.city
vm.setData({
province: province,
city: city,
latitude: latitude,
longitude: longitude
})
}
});
},
})
以上就是小程序获取地理位置的全部方法
