示例1: findLocationId
findLocationId(city: string): Observable<City[]> {
const uri = 'https://api.buienradar.nl/data/search/1.0/?query=' + city + '&country=BE&locale=nl-BE';
const result$: Observable<AxiosResponse> = this.httpService.get(uri);
return Observable.create((obs) => {
const cities: City[] = [];
result$.subscribe((data: AxiosResponse) => {
const dataIndex: number = data.data.length > 1 ? (data.data.length - 1) : 0;
if (data.data.length > 0) {
for (const singleCity of data.data[dataIndex].results) {
const uriPieces: string[] = singleCity.uri.split('/');
cities.push(new City(Number(uriPieces[uriPieces.length - 1]), singleCity.main, singleCity.sub));
}
}
}, (error) => {
console.log(error);
},
() => {
obs.next(cities);
obs.complete();
});
});
}示例2: City
return Observable.create((obs) => {
const cities: City[] = [];
result$.subscribe((data: AxiosResponse) => {
const dataIndex: number = data.data.length > 1 ? (data.data.length - 1) : 0;
if (data.data.length > 0) {
for (const singleCity of data.data[dataIndex].results) {
const uriPieces: string[] = singleCity.uri.split('/');
cities.push(new City(Number(uriPieces[uriPieces.length - 1]), singleCity.main, singleCity.sub));
}
}
}, (error) => {
console.log(error);
},
() => {
obs.next(cities);
obs.complete();
});
});示例3: subscribe
return RxJS.Observable.create(function subscribe(obs) {
input.subscribe(val => obs.next(val * 10),
err => obs.error(err),
() => obs.complete()
);
});示例4: setTimeout
