在使用uniapp获取定位的时候 uni.getLocation() 第一次打开手机的时候 会弹出 授权界面，但是有时候点错就不会再次弹出来了。今天做了个整理
创建 device.js文件
let system = uni.getSystemInfoSync(); // 获取系统信息
/**检查是否打开GPS功能（android）**/
export const checkOpenGPSServiceByAndroid = () => {
if (system.platform === 'android') { // 判断平台
openGps()
}else if (system.platform == "ios") {
//苹果打开对应的通知栏
uni.showModal({
title: "定位权限开启提醒",
content: "您还没有开启定位权限，无法定位，请前往设置！",
confirmText: "去设置",
success: function(res) {
if (res.confirm) {
var app = plus.ios.invoke("UIApplication", "sharedApplication");
var setting = plus.ios.invoke("NSURL", "URLWithString:", "app-settings:");
plus.ios.invoke(app, "openURL:", setting);
plus.ios.deleteObject(setting);
plus.ios.deleteObject(app);
}
}
});
}
}
/**
* 定位权限及弹出权限弹框 监听用户点击按钮
* **/
let num = 0;
export const openGps = () => {
plus.android.requestPermissions(
['android.permission.ACCESS_FINE_LOCATION'],
function(resultObj) {
console.log('resultObj---', resultObj);
var result = 0;
for (var i = 0; i < resultObj.granted.length; i++) {
var grantedPermission = resultObj.granted[i];
// console.log(6, '已获取的权限：' + grantedPermission);
result = 1
}
for (var i = 0; i < resultObj.deniedPresent.length; i++) {
var deniedPresentPermission = resultObj.deniedPresent[i];
// console.log(5, '拒绝本次申请的权限：' + deniedPresentPermission);
num += 1
result = 0
}
for (var i = 0; i < resultObj.deniedAlways.length; i++) {
var deniedAlwaysPermission = resultObj.deniedAlways[i];
// console.log(4, '永久拒绝申请的权限：' + deniedAlwaysPermission);
num += 1
result = -1
}
// 若所需权限被拒绝,则打开APP设置界面,可以在APP设置界面打开相应权限
if (result != 1) {
uni.showToast({
title: "请到系统设置打开定位服务功能！",
icon: "none",
duration: 1000
})
setTimeout(() => {
var Intent = plus.android.importClass("android.content.Intent")
var Settings = plus.android.importClass("android.provider.Settings")
var Uri = plus.android.importClass("android.net.Uri")
var mainActivity = plus.android.runtimeMainActivity()
var intent = new Intent()
intent.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS)
var uri = Uri.fromParts("package", mainActivity.getPackageName(), null)
intent.setData(uri)
mainActivity.startActivity(intent)
}, 1200)
}else {
//因为安卓手机 手机授权之后还需要打开定位服务功能所有当手机授权之后 调用下面的方法
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)
if (!mainSvr.isProviderEnabled(locationManager.GPS_PROVIDER)) {
uni.showModal({
title: '提示',
content: '请打开定位服务功能',
success(res) {
if (res.confirm) {
if (!mainSvr.isProviderEnabled(locationManager.GPS_PROVIDER)) {
var Intent = plus.android.importClass('android.content.Intent');
var Settings = plus.android.importClass('android.provider.Settings')
var intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS)
main.startActivity(intent) // 打开系统设置GPS服务页面
} else {
}
}
}
});
return
}
}
},
function(error) {
console.log('申请权限错误：' + error.code + " = " + error.message);
resolve({
code: error.code,
message: error.message
});
}
);
}
调用
import {checkOpenGPSServiceByAndroid } from '@/utils/device.js'
getGPS(){
uni.getLocation({
type: 'wgs84',
geocode:true,//设置该参数为true可直接获取经纬度及城市信息
success: function (res) {
this_.latitude = res.latitude
this_.longitude = res.longitude
},
fail: function (ress) {
//失败调用
checkOpenGPSServiceByAndroid()
}
})
}
