React-native-background-geolocation: json sending problem when sending data to server in background

Created on 23 Jul 2019 · 10Comments · Source: mauron85/react-native-background-geolocation

I'm registering locations with BackgroundGeolocation.on('location', (location) => {}); using asp.net core web api, but when I switch to the background, the format of the data is different and I get a 400 error from the server

I solved the problem. data arrives as an array, not an object

[HttpPost] ActionResult getlocation([FromBody] List<Location> location){} --> List add

On location doesn't follow postTemplate. It uses default format. That is intentional. The prefix post in property postTemplate suggest that.

EDIT. check https://github.com/mauron85/react-native-background-geolocation#location-event for location event data format.

mauron85 on 23 Jul 2019

so when I do so when accessing the server lng and lat he would call or latitude, longitude

cinkagan on 23 Jul 2019

When you're using built in http posting (options url and syncUrl), then plugin will always sent locations in format defined in postTemplate (background and foreground).

But you said, you registered BackgroundGeolocation.on('location', (location) => {}); This listener will always be called with Location Event format (not postTemplate format).

mauron85 on 23 Jul 2019

No problem when taken with BackgroundGeolocation.on('location', (location) => {}); but when I close the application I get 400 error from url

cinkagan on 23 Jul 2019

Yerleşik http gönderme (seçenekler urlve syncUrl) kullanırken, eklenti her zaman postTemplate'de (arka plan ve ön plan) tanımlanan biçimde konumlar gönderir.

Ama sen söyledin, kaydoldun BackgroundGeolocation.on('location', (location) => {});Bu dinleyici daima Konum Olay formatı ile çağrılacak (postTemplate formatı değil).

how postTemplate should be.how should I use the application while running in the background

cinkagan on 23 Jul 2019

` BackgroundGeolocation.on('location', (location) => {
BackgroundGeolocation.startTask(taskKey => {

            axios.post(API_BASE + 'konum', {
                latitude: location.latitude,
                longitude: location.longitude,
            }, config).then(result => {
                that.setState({ uyari: '' })
            }).catch(e => {
                var mesaj = {
                    tarih: moment().format("YYYY-MM-DD HH:mm:ss"),
                    mesaj: e.response.data
                }
                this.props.AppStore.saveUyari(mesaj);
            });

            BackgroundGeolocation.endTask(taskKey);
        });
    });`

there is no problem with that. There's a problem working in the background

cinkagan on 23 Jul 2019

Hi Kaan,
You don't need to use _BackgroundGeolocation.on('location'=>{})_ . Because already set url and postTemplete. These settings work both in the background and in the foreground.
Turkish:
location event'i içinde post yapmaya ihtiyacın yok çünkü zaten url ve postTemplate vermişssin. Bu şekilde uygulama ön veya arka planda belirttiğin url e post yapacaktır.
Çok tecrübem yok ama deneyimlediğim kadarıyla bu şekilde post yapıyor. Burada dikakt etmen gereken belirlediğin yarıcap ve mesafe aralığı (stationaryRadius ve distanceFilter)

On my server the json data post process works with postman but the data that comes with postTemplate is always null
postTemplate: { lat: '@latitude', lon: '@longitude' }
Asp.net core web api
My Model

public class Location
{
   public decimal lat{get;set;}
   public decimal lon{get;set;}
}

My Controller Function

[HttpPost]
ActionResult getlocation([FromBody] Location location){}

data I send with postman application

{
    "lat":1,
    "lon":33
}

that's how it works with postman
