使用Google地图检索当前位置

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？

解决方案

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：

如果您需要搜索，地图等更多内容，那么拿这个插件：

更新：

如果您使用cordova-plugin-googlemaps，那么它非常容易。从（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?

解决方案

There is a request limit of 2500 per day.

https://developers.google.com/maps/faq#usagelimits

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);
