angular-httpclient

I have a spring boot API that creates a pdf report and download it, if I call the API directly in the browser, the pdf is created and downloaded directly, but when I call that GET API from Angular 6 I get the following error: The Spring boot (java) code: @RequestMapping(value = "/app_report/en", method = RequestMethod.GET) @ResponseBody public void getEnRpt(HttpServletResponse response, @RequestParam("appNum") String appNum) throws JRException, IOException, SQLException { JasperReport jasperReport = JasperCompileManager.compileReport("./src/main/resources/jasperReports/App_created_en.jrxml");

Under my Angular6 app , i'm using HttpClient with some headers injection to my htpp calls to fetch data from my backend server : My service : @Injectable() export class LoadUserInfosService { public _headers = new HttpHeaders().set('Content-Type', 'application/json'); constructor(private httpClient: HttpClient) {} getUserPnsInfos(cuid): Observable<object> { const headers = this._headers.append('login', login); return this.httpClient.get(myBackUrl, {headers: headers}); } } My component where i'm subscribing to it : loadUserInfosFromPns(login) { this.loadUserInfosService.getUserPnsInfos(login)

i wanted to exclude some services using interceptor. app.module.js providers: [ UserService, RolesService, { provide: HTTP_INTERCEPTORS, useClass: TokenInterceptor, multi: true }, ], Login.service.ts return this.httpClient.post(this.appUrl + '/oauth/token', body.toString(), { headers, observe: 'response' }) .map((res: Response) => { const response = res.body; this.storeToken(response); return response; }) .catch((error: any) => { ErrorLogService.logError(error); return Observable.throw(new Error(error.status)); }); } To give this an answer not only in comments as requested ;-) To exclude some

I have written first test to test service class: service class: import { Injectable } from '@angular/core'; import {HttpClient} from '@angular/common/http' import {IComment} from "../../models/comments"; import {Observable} from "rxjs/observable"; import { mergeMap } from 'rxjs/operators'; @Injectable() export class CommentsDataService { public _url:string = "../../../../assets/json/comments.json"; constructor(private http: HttpClient) { } /** * Return Sample json for * Comment listing. * @returns {json) */ getComments():Observable<IComment> { return this.http.get<IComment>(this._url) } /** *

How can I modify my http call to handle(catch) for 500 server errors. I try calling an API but receive a '500 (Internal server error' in the 'err' part of the function. I would like to be able to catch it if possible but am not sure how. Is there a simple way to do this? call_http() { this.http.get<any>('/api/goes/here').subscribe(data => { this.result = data; }, err => { console.log(err); }); } I am not using any headers, map, errorhandler etc. This is just a basic call. If you want to intercept errors when using HttpClient service to make backend calls and don't repeat yourself in every call

I have a very simple service call and a jasmine test for it. Service call: myServiceCall(testId: number) : void { const url = `${this.url}/paramX/${testId}`; this.http.put(url, {},{headers: this.headers}).subscribe(); } My Test Method: it('should call myServiceCall', inject([MyService], (service: MyService) => { let testId = undefined; service.myServiceCall(testId); let req = httpMock.expectOne(environment.baseUrl + "/paramX/123"); expect(req.request.url).toBe(environment.baseUrl + "/paramX/123"); expect(req.request.body).toEqual({}); req.flush({}); httpMock.verify(); })); I get of course an
