请求使用Cordova地理位置插件的权限。

Question

我想了解一下，在使用cordova的这个插件时，如果用户拒绝了位置权限，是否有办法再次向用户请求位置权限？谢谢。 https://github.com/apache/cordova-plugin-geolocation

你可以使用cordova-diagnostic-plugin来实现此功能，例如：

cordova-diagnostic-plugin。

var deniedCount = 0;

function onError(error){
    console.error("The following error occurred: "+error);
}

function evaluateAuthorizationStatus(status){
    switch(status){
       case cordova.plugins.diagnostic.permissionStatus.NOT_REQUESTED:
           console.log("Permission not requested");
           requestAuthorization();
           break;
       case cordova.plugins.diagnostic.permissionStatus.DENIED:
           console.log("Permission denied");
           if(deniedCount < 3){
              deniedCount++;
              requestAuthorization();
           }else{
              // Are we sure we want to hassle the user more than 3 times?
           }
           break;
       case cordova.plugins.diagnostic.permissionStatus.DENIED_ALWAYS:
           console.log("Permission permanently denied");
           navigator.notification.confirm(
                "This app has been denied access to your location and it really needs it function properly. Would you like to switch to the app settings page to allow access?", 
                function (i) {
                    if (i === 1) {
                        cordova.plugins.diagnostic.switchToSettings();
                    }
                }, "Location access denied", ['Yes', 'No']);
           break;
       case cordova.plugins.diagnostic.permissionStatus.GRANTED:
           console.log("Permission granted always");
           // Yay! use location
           break;        
   }
}

function requestAuthorization(){
    cordova.plugins.diagnostic.requestLocationAuthorization(evaluateAuthorizationStatus, onError);
}

function checkAuthorization(){
    cordova.plugins.diagnostic.getLocationAuthorizationStatus(evaluateAuthorizationStatus, onError);
}

checkAuthorization();
