我正在尝试使用API​​ URL.我用以下代码调用API.

import {HttpClient, HttpClientModule, HttpParams} from "@angular/common/http";

@Injectable()
export class PropertyPrefService {

    constructor(private http: HttpClient,
                private configurationService:Configuration) {}

    public searchProjects(propFilter:string):any{
        let temp:any;
        const options = propFilter ?
        {
            params: new HttpParams().set('query', propFilter)
        } : {};

        return this.http.get<any>(this.configurationService.propertySystemApiUrl, options)
                    .subscribe((results:any) => {
                        console.log(results);
                    });
    }

在Angular代码中,我没有得到任何响应,并且收到错误:

(未知网址)的Http失败响应:0未知错误".

但是,当我在Chrome上打开开发人员工具时发出请求时,我看到响应是从服务器收到的.

URL是"https:// ..."URL而不是"http:// ...".

我正在Angular 4中编写一个Authguard,以防止在没有登录的情况下访问路由.但是,我收到了这个错误.以下是Authgaurd和Routing in App模块中的代码.请帮助解决问题.

// Authgaurd代码

RouterStateSnapshot } from '@angular/router';
import { Store } from '';

import { Globals } from '../../app.global';
import { CRMStorageService } from '../services/storage.service';

export class AuthGuard implements CanActivate {

constructor(private router: Router,private storageService: StorageService) {
