我已经使用 laravel 5.5 在我的 angular 5 项目之一中安装了 ngx-pagination。我的 Angular 项目正在使用 Laravel 的 API。我在 HTML、ts 和服务文件中包含以下内容，如下所示：
// ts file
getPage(number){
this.productService.getURLpagengx(number).subscribe(data => {
this.products = data.products.data;
this.products_paging = data.products;
});
}
// service file
getURLpagengx(no): Observable<any>{
const url = '${this.url}/api/product?page='+no;
return this.http.get(url,{headers: new HttpHeaders({Authorization:'Bearer '+ this.token})});
} <div class="row">
<article class="col-md-4" *ngFor="let product of products | paginate: { itemsPerPage: 1, currentPage: p, totalItems: products_paging.total }">
<div class="mt-3 mb-3">
<div class="col-md-12">
<div class="font-weight-bold">{{product.product_name}}</div>
<p>{{product.description}}</p>
<p>{{product.rating}}</p>
<div class="pt-2 pb-2 border-top border-bottom">
<div class="mt-1">
</div>
</div>
</div>
</div>
</article>
</div>我的分页运行良好，但分页中当前单击的按钮未激活/未激活（例如蓝色）。
