www/index.html 想使用您当前的位置 - Ionic Framework [英] www/index.html would like to use your current location - Ionic Framework

问题描述

我搜索了与基于地理位置的警报问题相关的各种论坛和帖子；出于某种原因，在我的情况下没有任何技术起作用.

I searched various forums and posts related to GeoLocation based alert issue; For some reason no technique worked in my case.

在我的 Ionic 框架项目中添加了cordova-plugin-geolocation"插件.

Added "cordova-plugin-geolocation" plugin to my Ionic Framework Project.

在 $ionicPlatform.ready(...)

navigator.geolocation.getCurrentPosition(function(position) {
    var coords = {};
    coords.updated = new Date();
    coords.latitude = position.coords.latitude.toFixed(6);
    coords.longitude = position.coords.longitude.toFixed(6);
    coords.altitude = position.coords.altitude + ' m';
    coords.accuracy = position.coords.accuracy + ' m';
    coords.altitudeAccuracy = position.coords.altitudeAccuracy + ' m';
    coords.heading = position.coords.heading + 'u00b0';
    coords.speed = position.coords.speed + ' m/s';
    console.log('Fetched Location...' + geoText);
    return position;
}, function(err) {
    Logger.error(err.message);
}, {
    timeout: 10000,
    enableHighAccuracy: true
});

当我在 iOS/Android 中模拟/运行时，它会抛出

When I emulate / run in iOS / Android it throws

错误消息:/www/index.html 想使用您的位置

Error Message: /www/index.html would like to use Your Location

如果有人可以提供帮助，我将不胜感激.

I would greatly appreciate if someone can help.

推荐答案

我按照这个解决了这个问题

I resolved this issue by following this

为 Location 创建了一个新的 Service，如下所示

Created a new Service for Location as follows

.service('LocationService', function($q) {
        this.fetch = function() {
            var deferred = $q.defer();
            navigator.geolocation.getCurrentPosition(function(position) {
                deferred.notify('Fetching Location...')
                var coords = {};
                coords.updated = new Date();
                coords.latitude = position.coords.latitude.toFixed(6);
                coords.longitude = position.coords.longitude.toFixed(6);
                coords.altitude = position.coords.altitude + ' m';
                coords.accuracy = position.coords.accuracy + ' m';
                coords.altitudeAccuracy = position.coords.altitudeAccuracy + ' m';
                coords.heading = position.coords.heading + 'u00b0';
                coords.speed = position.coords.speed + ' m/s';
                deferred.resolve(position);
            }, function(err) {
                deferred.reject(err);
            }, {
                timeout: 10000,
                enableHighAccuracy: true
            });
            return deferred.promise;
        }
    })

那么我们将服务称为

Location.fetch().then(function(pos){...}) 

在 $ionicPlatform.ready(..) 内或添加到按钮 ng-click 以获取位置.

within $ionicPlatform.ready(..) or add to a button ng-click to fetch location.

根本原因:我相信，当我们在任何控制器中直接调用 Location.fetch() 或 navigator.geolocation.. 时，它会在最初加载控制器时执行.这可能会在 Cordova/Ionic 平台准备好之前被触发，因此我们会收到额外的/不需要的警报，指出 www/index.html 正在尝试使用位置作为我的问题状态.

Root Cause: What I believe is that when we call Location.fetch() or navigator.geolocation.. directly in any controllers, its executed when the controllers are loaded initially. This might get fired before Cordova / Ionic platform is ready and hence we get the additional / unwanted alert mentioning that www/index.html is trying to use location as my problem states.
