}

constructor(private http: Http) {
console.log(‘Hello RestServiceProvider Provider’);
}

signUp() {
return new Promise(resolve => {
let headers = new Headers();
headers.append(‘Content-Type’, ‘application/json; charset=utf-8’);
let opts = new RequestOptions();
opts.headers = headers;
this.http.post(this.apiUrl + ‘/signup’, this.data, opts).subscribe(data => {
resolve(data);
console.log(JSON.stringify(data));
}, err => {
resolve(err);
console.log(‘error’);
console.log(JSON.stringify(err));
});
});
}

My error

Works in chrome with http://localhost:8100 but not working in simulator with file:// in Allowed Origins (CORS)

Based on the description of the issue, your situation is likely the same one being tracked at (https://github.com/auth0/auth0-cordova/issues/42) so if you haven’t done so already you want to check that issue for some additional information.

it is OK now
it is because --livereload
I became crazy…

I followed this tutorial ant it is OK :
