点击Ionic 4（Newsapi）上不同新闻的相同新闻详情

Question

我在这里关注一个教程：https://www.youtube.com/watch?v=NJ9C7iY9350。无法理解为什么我点击新闻并且新闻细节总是一样的，我正在检查我的代码和它在github中的相同。但不知道为什么看不到每条新闻的新闻细节，只是留下我点击的第一个新闻。

附上我的代码：

新闻

---

TS

    goToNews(article) {
    this.newsService.currentArticle = article;
    console.log(article)
    this.router.navigate(['/tabs/news-detail']);
}

    getNews() {
    this.newsService.getData(`top-headlines?countries=${this.selectedCountry}&category=technology`)
        .subscribe(data => {
            this.news = data;
            console.log(this.selectedCountry)
        })
}

HTML

    <ion-list *ngIf="!isResult">
    <ion-item *ngFor="let country of countries" (click)="selectCountry(country)">
        {{ country }}
    </ion-item>
</ion-list>
<ion-card *ngFor="let article of news?.articles" (click)="goToNews(article)">
    <ion-card-content>
        <ion-card-title>{{ article.title }}</ion-card-title>
    </ion-card-content>
</ion-card>

新闻 - 细节

TS

export class NewsDetailPage implements OnInit {

article

constructor(private newsService: NewsService) { }

ngOnInit() {
    this.article = this.newsService.currentArticle;
    console.log(this.article)
}
}

tabs.router.module.ts

 ....
{ path: 'news', loadChildren:'../news/news.module#NewsPageModule' },
{ path: 'news-detail', loadChildren:'../news-detail/news-detail.module#NewsDetailPageModule' },
....

Answer 1

最后我解决了它：

ionViewWillEnter() {
    this.article = this.newsService.currentArticle;
    console.log(this.newsService.currentArticle)
}

这样做总是随着我点击一个新的“新闻”而改变
