如何增加 angular 请求超时

Question

I have a request take about 2-5 minutes but it always break at 30s
Is there any way to increase request timeout or prevent request was canceled automatically with angular 8.x?

Answer 1

You need to use the timeout operator. Since rxjs 5.5.2 you need to use the pipe method with lettable operators. And assuming you are using the HttpClient to make your requests, there is no need for a map(response => response.json()).

Like this:

import { timeout, catchError } from 'rxjs/operators'; import { of } from 'rxjs/observable/of';

http.get(' https://example.com ').pipe( timeout(2000), catchError(e => { // do something on a timeout return of(null); }) )
