AFURLRequestSerialization error app crash down


#1

Hello,

I got an error when using the ionic native http to make backend calls, the app crashes down when making a login call on ios device. But the same works with angular http.

AFURLRequestSerialization.m
Signal SIGABRT (mutableRequest setValue ….)


#pragma mark - AFURLRequestSerialization

                               withParameters:(id)parameters

{
    NSParameterAssert(request);

    NSMutableURLRequest *mutableRequest = [request mutableCopy];

    [self.HTTPRequestHeaders enumerateKeysAndObjectsUsingBlock:^(id field, id value, BOOL * __unused stop) {
        if (![request valueForHTTPHeaderField:field]) {
            [mutableRequest setValue:value forHTTPHeaderField:field];
        }
    }];

Here is my code how I using the native http call

@Injectable()
export class HttpNativeProvider {
constructor(private http: HTTP) {
}

public callLogin(){
	let headers = new Headers({'Content-Type': 'application/x-www-form-urlencoded'});
	let options = new RequestOptions({headers: headers, withCredentials: true});
	let params: URLSearchParams = new URLSearchParams();
	params.set('target', 'XXX');
	params.set('username', XXX);
	params.set('password', XXX);
	return this.post(XXX, params, options)
  .map(this.returnData)
  .catch(this.handleError);
}

private post(url, params?: any, options: any = {}) {
	let responseData = this.http.post(url, params, options);
	return Observable.fromPromise(responseData);
}

private returnData(res: Response) {
	if (JSON.stringify(res.text()).indexOf('error') === -1) {
	  return res || {};
	} else {
	  throw {message: 'Error occured in Login' + res};
	}
}

private handleError(error: any) {
	return Observable.throw(error.message);	
} 
}
