Ionic: 3.19.0
Angular: 5.0.3
Node: 6.9.5
I have several Angular providers using HttpClient in my Ionic app hitting a Node.js server for data getting and storing.
I’m noticing an odd behavior whenever my node server is down or stopped (ERR_CONNECTION_REFUSED error).
When I run the app on my dev machine with ionic serve, my provider hits the error callback whitin 2 to 4 seconds.
However, when I do the same on the actual built app (or running it with Ionic DevApp), the error callback gets hit a good 120 to 135 seconds after the request fires. Do I need to handle ERR_CONNECTION_REFUSED errors specially or is this a bug?
Below is the get method code from one of my app services:
getUsers(key: number = -1): Observable<Response> {
let self = this;
return this.http
.get( this.apiURL, {headers: this.jsonHeader} )
.map(response => {
let json = response.json();
return key > -1 && json[key] ? json[key] : json;
})
.catch( (err) => {
return self.handleError(err);
})
}
And here is the method which calls this service from an Ionic page:
getUserData(){
let self = this;
this.loadingService.setLoadingState(true);
this.mongoService.getUsers().subscribe(
(response: any) => {
self.loadingService.setLoadingState(false);
this.mongoUsers = response;
console.log("Mongo Users:", this.mongoUsers);
},
(err: any) => {
self.loadingService.setLoadingState(false);
alert('user error');
}
)
}
Thanks!
