使用Google地图检索当前位置 [英] Retrieving Current location using Google Maps
问题描述
我的代码检查当前用户的位置，然后使用cordova的地理位置插件加载附近的所有商店，包括距离位置。
这是我的代码：
.factory（'GSSearchLocationService'，['$ cordovaGeolocation'，'$ q'，function（$ cordovaGeolocation，$ q）{
function _getLocation（options）{
var callStart = options.callStart;
var deferred = options.deferred;
var attempt = options.attempt;
var othOptions = options.othOptions;
deferred.notify（{attempt：attempt，message：'Searching attempt'+ attempt，lastAccuracy：options.lastAccuracy}）;
var getLocOptions = {
enableHighAccuracy ：othOptions.gps.enableHighAccuracy，
timeout：othOptions.gps.timeout * 100，
maximumAge：0
};
var locWatch = $ cordovaGeolocation.watchPosition（ getLocOptions）;
locWatch.then（
null，
function（ err）{
locWatch.clearWatch（）;
deferred.reject（{err：err}）;
}，
函数（位置）{
var callEnd = new Date（）。getTime（）/ 1000;
locWatch.clearWatch（）;
if（position.coords.accuracy&& position.coords.accuracy< = othOptions.gps.accuracy）{
//这是很好的准确性，然后接受
deferred.resolve （{status：0，position：position}）; $（b $ b）else if（（callEnd - callStart）< othOptions.gps.timeout）{
//继续尝试，直到配置的等待时间。如果超过，则返回。
options.attempt ++;
options.lastAccuracy = Math.round（position.coords.accuracy * 100）/ 100;
options.minAccuracy = options.minAccuracy || options.lastAccuracy; //默认
options.minAccuracy = options.minAccuracy< options.lastAccuracy？ options.lastAccuracy：options.minAccuracy;
_getLocationWrapper（options）;
} else {
othOptions.gps.timeout
deferred.reject（{error：{code：-999，message：Could not get location。< br>最精确度是 + options.minAccuracy +mts。< br>尝试检查空旷区域的位置或尝试调整到可接受的准确度。}}）;
}
}
）;
$ b函数_getLocationWrapper（options）{
var locCB = function（）{return _getLocation（options）;};
if（options.attempt == 1）{
locCB（）;
} else {
setTimeout（locCB，options.othOptions.gps.interval * 1000）;
}
}
return {
getCurrentLocation：function（options）{
var deferred = $ q.defer（）;
callStart = new Date（）。getTime（）/ 1000;
_getLocationWrapper（{callStart：callStart，deferred：deferred，othOptions：options，attempt：1}）;
return deferred.promise;
}
};
}]）
直到前几天，我尝试获得当前位置我收到以下错误消息：
消息：网络位置提供程序位于'https://www.googleapis.com /'：返回的错误代码为403.
任何人都知道我可以如何解决这个问题？
每天有2500个请求限制。

另一个原因可能是，您使用的是Google的旧API。
如果您需要的唯一东西是地理位置，这个插件：
https：/ /www.npmjs.com/package/cordova-plugin-geolocation
如果您需要搜索，地图等更多内容，那么拿这个插件：
https：// github.com/mapsplugin/cordova-plugin-googlemaps
更新：
如果您使用cordova-plugin-googlemaps，那么它非常容易。从 https://github.com/mapsplugin/cordova-plugin-googlemaps上的文档/ wiki / Map （获取我的位置）：
var onSuccess = function（location）{
var msg = [当前位置：\\\
，
latitude：+ location.latLng.lat，
longitude：+ location.latLng.lng，
speed ：+ location.speed，
time：+ location.time，
bearing：+ location.bearing] .join（\\\
）;
map.addMarker（
'position'：location.latLng，
'title'：msg
}，function（marker）{
marker .showInfoWindow（）;
}）;
};
var onError =函数（msg）{
alert（error：+ msg）;
};
map.getMyLocation（onSuccess，onError）;
My code checks current user position and then loads all nearby stores including distance to location using cordova's geolocation plugin.
This is my code:
.factory('GSSearchLocationService',['$cordovaGeolocation', '$q',function($cordovaGeolocation, $q){
function _getLocation(options){
var callStart = options.callStart;
var deferred = options.deferred;
var attempt = options.attempt;
var othOptions = options.othOptions;
deferred.notify({attempt: attempt, message:'Searching attempt '+attempt, lastAccuracy : options.lastAccuracy});
var getLocOptions = {
enableHighAccuracy: othOptions.gps.enableHighAccuracy,
timeout: othOptions.gps.timeout * 100,
maximumAge: 0
};
var locWatch = $cordovaGeolocation.watchPosition(getLocOptions);
locWatch.then(
null,
function(err) {
locWatch.clearWatch();
deferred.reject({err:err});
},
function(position) {
var callEnd = new Date().getTime() / 1000;
locWatch.clearWatch();
if ( position.coords.accuracy && position.coords.accuracy <= othOptions.gps.accuracy ) {
// This is good accuracy then accept it
deferred.resolve({status:0, position:position});
} else if ( (callEnd - callStart) < othOptions.gps.timeout ) {
// Keep trying till the configured wait time. If exceeds then return back.
options.attempt++;
options.lastAccuracy = Math.round(position.coords.accuracy * 100) / 100;
options.minAccuracy = options.minAccuracy || options.lastAccuracy; // Default
options.minAccuracy = options.minAccuracy < options.lastAccuracy ? options.lastAccuracy : options.minAccuracy;
_getLocationWrapper(options);
} else {
othOptions.gps.timeout
deferred.reject( {error:{code:-999, message:"Could not get location.<br>Most min accuracy is "+options.minAccuracy+" mts.<br>Try to check location in open area or try adjusting to acceptable accuracy."}} );
}
}
);
}
function _getLocationWrapper(options) {
var locCB=function(){return _getLocation(options);};
if ( options.attempt == 1 ) {
locCB();
} else {
setTimeout(locCB, options.othOptions.gps.interval*1000);
}
}
return {
getCurrentLocation : function (options) {
var deferred = $q.defer();
callStart = new Date().getTime() / 1000;
_getLocationWrapper({callStart:callStart, deferred:deferred, othOptions:options, attempt:1});
return deferred.promise;
}
};
}])
It worked fine until a few days ago, when I try to get the current position I get the following error:
message: "Network location provider at 'https://www.googleapis.com/' : Returned error code 403.
Anyone know how I can get this to work?
There is a request limit of 2500 per day.

Another reason could be, that you are using an old API from Google.
If the only thing you need is the geolocation, then use this plugin:
https://www.npmjs.com/package/cordova-plugin-geolocation
If you need more things like searching, maps, …, then take this plugin:
https://github.com/mapsplugin/cordova-plugin-googlemaps
Update:
If you use cordova-plugin-googlemaps then it is very easy. From the docs at https://github.com/mapsplugin/cordova-plugin-googlemaps/wiki/Map (Get my location):
var onSuccess = function(location) {
var msg = ["Current your location:\n",
"latitude:" + location.latLng.lat,
"longitude:" + location.latLng.lng,
"speed:" + location.speed,
"time:" + location.time,
"bearing:" + location.bearing].join("\n");
map.addMarker({
'position': location.latLng,
'title': msg
}, function(marker) {
marker.showInfoWindow();
});
};
var onError = function(msg) {
alert("error: " + msg);
};
map.getMyLocation(onSuccess, onError);
