从角度服务管道传输时,rxjs catchError无法正常工作 [英] rxjs catchError not working when piped from angular service
本文介绍了从角度服务管道传输时,rxjs catchError无法正常工作的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
使用redux和Angular,我具有以下效果:
Using redux and Angular, I have the following effect:
@Effect()
public authenticate: Observable<Action> = this.actions
.ofType(AUTHENTICATE)
.pipe(
map((action: AuthenticateAction) => action.payload),
switchMap(payload => {
return this.userService.authenticateUser(payload.email, payload.password).pipe(
map(auth => new AuthenticationSuccessAction({ auth: auth })),
catchError(error => of(new HttpErrorAction({ error: error })))
);
})
);
服务:
public authenticateUser(email: string, password: string): Observable<IAuthentication> {
const formData: FormData = new FormData();
formData.append('email', email);
formData.append('password', password);
return this.httpClient.post('/api/auths/useraccounts', formData) as Observable<IAuthentication>;
}
当POST失败时,将永远不会调度HttpErrorAction.
When the POST fails, the HttpErrorAction never gets dispatched.
推荐答案
结果我忘了我有一个HttpInterceptor,它像这样捕获了HTTP错误:
Turns out I forgot I had an HttpInterceptor that I caught http errors like so:
return next.handle(authReq).pipe(catchError(
(error) => {
return of(error);
}
如果我想使错误冒泡,直到达到效果,我会做类似的事情:
If I wanted to bubble the error up to the effect i'd do something like:
return Observable.throw(error);
使用更新的rxjs版本进行更新:
Update with newer versions of rxjs:
return throwError(error);
