我正在尝试在angular2中构建chrome扩展,其中一部分将显示用户的chrome历史记录。组件:

/// <reference types="chrome/chrome-app"/>
import { Http, Response } from '@angular/http';
import 'rxjs/add/operator/toPromise';
import { Component, OnInit } from '@angular/core';
import { mockHistory } from  './chrome-history-mock';

@Component({
  selector: 'app-chrome-history',
  templateUrl: './chrome-history.component.html',
  styleUrls: ['./chrome-history.component.css']
})
export class ChromeHistoryComponent implements OnInit {
  historyData: any = [];
  constructor(private http: Http) {}

  ngOnInit() {
    var microsecondsPerWeek = 1000 * 60 * 60 * 24 * 7;
    var oneWeekAgo = (new Date).getTime() - microsecondsPerWeek;
    chrome.history.search({
     'text': '',
      'startTime': oneWeekAgo,
      // 'maxResults': 10
    }, this.constructHistory);
  }
  constructHistory(historyObj): any {
    console.log(historyObj[0]);                     //prints first obj
    this.historyData = historyObj;
    console.log(this.historyData.length);           //prints 100
    console.log(historyObj);                        //prints data
    console.log(JSON.stringify(historyObj));        //prints data
    console.log(JSON.stringify(this.historyData));  //prints data
  }
}

模板:

<ul  *ngIf="historyData?.length > 0">
<li *ngFor="let item of historyData | async">
  <div class="history-item"><input type="checkbox" />{{item.title}}</div>
  <span class="history-url">{{item.url}}</span>
</li>

我在回调函数constructHistory中获得响应,并且能够将其设置为类属性historyData,因为我可以在控制台日志中看到,但是这不会显示在模板中。我试图找到答案超过3天。搜索了很多博客,但无法找到任何解决方案。大多数是关于http.get案例中的数据绑定。也试过异步管但无法解决。抱歉,代码格式化。任何帮助表示赞赏。
