首先需要申请高德账号并把开发程序给绑定，这里直接跳过了

然后在manifest.json中进行配置，这里的key都是图1中配置得到的key

首先先检查手机是否打开了定位权限，如果没有就弹框引导用户打开手机权限

export const openPosition = ()=>{

let system = uni.getSystemInfoSync()

if(system.platform === 'android'){//判断平台

var context = plus.android.importClass("android.content.Context")

var locationManager = plus.android.importClass("android.location.LocationManager")

var main = plus.android.runtimeMainActivity()

var mainSvr = main.getSystemService(context.LOCATION_SERVICE)

console.log('GPS',mainSvr.isProviderEnabled(locationManager.GPS_PROVIDER))

if(!mainSvr.isProviderEnabled(locationManager.GPS_PROVIDER)){

uni.showModal({

title:'提示',

content:'请打开定位服务功能',

showCancel:false,

success() {

if(!mainSvr.isProviderEnabled(locationManager.GPS_PROVIDER)){

let main = plus.android.runtimeMainActivity();

let Intent = plus.android.importClass("android.content.Intent");

let mIntent = new Intent('android.settings.ACTION_SETTINGS');

main.startActivity(mIntent);//打开系统设置GPS服务页面

}else{

uni.showToast({

title:'定位功能已启动',

duration:2000

})

}

}

})

}

}

}

先通过uniapp的api获取当前的地理位置坐标，然后通过高德api进行解析，获取地理位置数据

getCurLocation(){

uni.getLocation({

geocode:true,

type: 'gcj02',

success:async (res)=>{

let { pois } = await posToCity(

{

latitude: res.latitude,

longitude: res.longitude,

},

1

);

this.address = pois[0].title

this.latitude = res.latitude

this.longitude = res.longitude

uni.setStorageSync('latitude',res.latitude)

uni.setStorageSync('longitude',res.longitude)

this.curAddress = store.state.address.curPickAddress.title

}

})

}

// 高德坐标解析

export const posToCity = async (location, extensions = 0) => new Promise((resolve, reject) => {

uni.request({

url: `https://restapi.amap.com/v3/geocode/regeo`,

method: 'GET',

data: {

key: gdMapKey,

location: `${location.longitude},${location.latitude}`,

extensions: extensions ? 'all' : 'base'

},

success: ({data}) => {

const {status, info, regeocode} = data

if (status === '1') {

// console.log(regeocode)

if ('pois' in regeocode) {

regeocode.pois = regeocode.pois.filter(item => typeof item.address === 'string' && typeof item.location === 'string').map(item => ({

id: item.id,

title: item.name,

address: item.address,

location: {

lat: item.location.split(',')[1],

lng: item.location.split(',')[0]

}

}))

}

resolve(regeocode)

} else {

reject(info)

}

},

fail: err => {

reject(err)

}

})

})

最后拿到数据进行渲染，得到成果图
