我不熟悉传递函数的概念.我如何调用GetItemsAsync()并在没有任何条件的情况下返回所有内容？

var items = await Respository.GetItemsAsync(d => !d.Completed);

    public async Task<IEnumerable<T>> GetItemsAsync(Expression<Func<T, bool>> predicate)
    {
        IDocumentQuery<T> query = client.CreateDocumentQuery<T>(
            UriFactory.CreateDocumentCollectionUri(DatabaseId, CollectionId),
            new FeedOptions { MaxItemCount = -1 })
            .Where(predicate)
            .AsDocumentQuery();

        List<T> results = new List<T>();
        while (query.HasMoreResults)
        {
            results.AddRange(await query.ExecuteNextAsync<T>());
        }

        return results;
    }

我需要如何设置HttpInterceptor？oidcSecurityService没有定义。

将HttpClient让你写拦截器。一个常见的用例是拦截任何传出的 HTTP 请求并添加授权标头。请记住，OidcSecurityService通过构造函数注入拦截器会导致循环依赖。为避免这种情况，请改用注射器。

@Injectable()
export class AuthInterceptor implements HttpInterceptor {
    private oidcSecurityService: OidcSecurityService;

    constructor(private injector: Injector) {}

    intercept(req: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {
        let requestToForward = req;

        if (this.oidcSecurityService === undefined) {
            this.oidcSecurityService = this.injector.get(OidcSecurityService);
        }
        if (this.oidcSecurityService !== undefined) {
            let token = this.oidcSecurityService.getToken();
            if (token !== '') {
                let tokenValue = 'Bearer ' + token;
                requestToForward = req.clone({ setHeaders: { Authorization: tokenValue } });
            }
        } else {
            console.debug('OidcSecurityService …

我的应用程序使用身份服务器，并且一旦重定向回来，我会将用户名存储在会话变量中。

该名称未显示，只有刷新页面才会显示。如何纠正这个问题？

import { Component, OnInit } from "@angular/core";
import { Router } from "@angular/router";
import { environment } from '../../environments/environment';

@Component({
  selector: "app-header",
  templateUrl: "./header.component.html",
  styleUrls: ["./header.component.css"]
})
export class HeaderComponent implements OnInit {
  navLinks: any[];
  activeLinkIndex = -1;
  displayName: string;
  logoutUrl: string;

  constructor(private router: Router) {
    this.navLinks = [
      {
        label: "Projects",
        link: "project-list",
        index: 0
      }
    ];    
  }
  ngOnInit(): void {
    this.router.events.subscribe(res => {
      this.activeLinkIndex = this.navLinks.indexOf(
        this.navLinks.find(tab => tab.link === "." + this.router.url)
