I'm facing a timeout issue with an Angular 8 app. My application needs to send a POST query to a a java backend server which will process a script for 7-8 minutes.The java app continues processing but because of the timeout, I won't be able to read the response .i tried the proposed solution in this link Default and specific request timeout and i was able to decrease the timeout .Unfortunately when i set a large timeout value (900000) , i get a timeout issue after 4min . I'm not facing the problem when i test the POST query with Postman .
This is the HttpInterceptor .
import { Inject, Injectable, InjectionToken } from '@angular/core';
import { HttpEvent, HttpHandler, HttpInterceptor, HttpRequest } from '@angular/common/http';
import { Observable } from 'rxjs';
import { timeout } from 'rxjs/operators';
export const DEFAULT_TIMEOUT = new InjectionToken<number>('defaultTimeout');
@Injectable()
export class TimeoutInterceptor implements HttpInterceptor {
constructor(@Inject(DEFAULT_TIMEOUT) protected defaultTimeout: number) {
}
intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
return next.handle(req).pipe(timeout(900000));
}
}
app.modules
providers: [
[{ provide: HTTP_INTERCEPTORS, useClass: TimeoutInterceptor, multi: true }],
[{ provide: DEFAULT_TIMEOUT, useValue: 900000 }],
...
],
my service
import(docType:any,docContent:any){
let params = new HttpParams();
params = params.append('docType', docType);
params = params.append('docContent', docContent);
return this.http.post<any>(`${BASE_PATH}/repriseManager/importAgreements`,{docType,docContent});
}
