由于我将代码更新到新的 Rxjs 6,我不得不像这样更改拦截器代码:
auth.interceptor.ts:
...
return next.handle(req).pipe(
tap((event: HttpEvent<any>) => {
if (event instanceof HttpResponse) {
// do stuff with response if you want
}
}),
catchError((error: any) => {
if (error instanceof HttpErrorResponse) {
if (error.status === 401) {
this.authService.loginRedirect();
}
return observableThrowError(this.handleError(error));
}
})
);
而且我无法测试 rxjs 运算符“tap”和“catchError”。
实际上我只能测试是否调用了管道:
it('should intercept and handle request', () => {
const req: any = {
clone: jasmine.createSpy('clone')
};
const next: any = {
handle: () => next,
pipe: () => next
};
spyOn(next, 'handle').and.callThrough();
spyOn(next, 'pipe').and.callThrough();
interceptor.intercept(req, next);
expect(next.handle).toHaveBeenCalled();
expect(next.pipe).toHaveBeenCalled();
expect(req.clone).toHaveBeenCalled();
});
关于如何监视 rxjs 操作员的任何帮助
