uniapp获取当前位置及检测授权定位权限

效果图

Android设备

• 点击 “设置”，跳转应用信息，打开“权限即可”；

创建js文件

permission.js

• 新建 .js 文件，例： permission.js
• 管理相关权限，例相册、相机等，可以写在此文件中
• 根据不同平台，处理向系统请求权限

/// null = 未请求，1 = 已允许，0 = 拒绝|受限, 2 = 系统未开启var isIOSfunction location() {var result = 0;var cllocationManger = plus.ios.import("CLLocationManager");var enable = cllocationManger.locationServicesEnabled();var status = cllocationManger.authorizationStatus();if (!enable) {result = 2;} else if (status === 0) {result = null;} else if (status === 3 || status === 4) {result = 1;} else {result = 0;}plus.ios.deleteObject(cllocationManger);return result;
}function requestIOS(permissionID) {return new Promise((resolve, reject) => {switch (permissionID) {case "location":resolve(location());break;default:resolve(0);break;}});
}function requestAndroid(permissionID) {return new Promise((resolve, reject) => {plus.android.requestPermissions([permissionID],function(resultObj) {var result = 0;for (var i = 0; i < resultObj.granted.length; i++) {var grantedPermission = resultObj.granted[i];console.log('已获取的权限：');result = 1}for (var i = 0; i < resultObj.deniedPresent.length; i++) {var deniedPresentPermission = resultObj.deniedPresent[i];console.log('拒绝本次申请的权限：');result = 0}for (var i = 0; i < resultObj.deniedAlways.length; i++) {var deniedAlwaysPermission = resultObj.deniedAlways[i];console.log('永久拒绝申请的权限：');result = -1}resolve(result);},function(error) {resolve({code: error.code,message: error.message});});});
}function gotoAppPermissionSetting() {if (permission.isIOS) {var UIApplication = plus.ios.import("UIApplication");var application2 = UIApplication.sharedApplication();var NSURL2 = plus.ios.import("NSURL");var setting2 = NSURL2.URLWithString("app-settings:");application2.openURL(setting2);plus.ios.deleteObject(setting2);plus.ios.deleteObject(NSURL2);plus.ios.deleteObject(application2);} else {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);}
}const permission = {get isIOS(){return typeof isIOS === 'boolean' ? isIOS : (isIOS = uni.getSystemInfoSync().platform === 'ios')},requestIOS: requestIOS,requestAndroid: requestAndroid,gotoAppSetting: gotoAppPermissionSetting
}export default permission

location.js

• 检测当前权限
• 获取当前位置
• 拒绝授权，弹窗提示
• 跳转App应用设置，打开位置权限

import permision from '@/common/js/permission.js'
import store from '@/store/index.js'export async function getLocation(cb) {// #ifdef APP-PLUSlet status = await checkPermission();if (status !== 1) {return status;}// #endifif (typeof cb == 'function') cb && typeof cb == 'function' && cb(status)doGetLocation();
}/*** 获取当前位置信息*/
export const doGetLocation = () => {uni.getLocation({success: (res) => {// 根据个人所需处理store.commit('SET_LOCATION', {lng: res.longitude,lat: res.latitude});console.log('当前位置：', res.longitude, res.latitude);},fail: (err) => {if (err.errMsg.indexOf("auth deny") >= 0) {uni.showToast({title: "访问位置被拒绝",icon: 'none'})} else {uni.showToast({title: err.errMsg,icon: 'none'})}}})
}/*** 检测定位权限*/
async function checkPermission() {let status = permision.isIOS ? await permision.requestIOS('location') :await permision.requestAndroid('android.permission.ACCESS_FINE_LOCATION');if (status === null || status === 1) {status = 1;} else if (status === 2) {uni.showModal({content: "系统定位已关闭",showCancel: false,success: function(res) {}})} else if (status.code) {uni.showModal({content: status.message})} else {uni.showModal({content: "为了您更好的体验App蓝牙功能，需要获取位置信息，请点击设置开启定位权限",confirmText: "设置",success: function(res) {if (res.confirm) {permision.gotoAppSetting();}}})}return status;
}const location = {getLocation
}
export default location;

使用

<button type="primary" @click="getLocation">获取位置</button>

import location from '@/common/js/location.js'/*** 获取位置*/
getLocation() {location.getLocation();
}

• 回调

location.getLocation((res) => {if (res != 1) return;// xxx
});
