如何从angular2中获取wordpress中的下一篇和之前的帖子

如何获取WordPress中角色2中的下一篇和之前的帖子？

我使用WordPress作为后端和角2作为前端。我通过使用WP rest API（../WP/v2/posts）获得了WordPress的所有帖子。我想下一个和以前的帖子JSON在前端展现提前采用了棱角分明2.

感谢...请帮助任何人......

import { Component, OnInit } from '@angular/core'; 
import { SingleService } from './singleproject.service'; 

import { Router, ActivatedRoute} from '@angular/router'; 

@Component({ 
    selector: 'app-singleproject', 
    templateUrl: './singleproject.component.html', 
    styleUrls: ['./singleproject.component.css'], 
    providers: [SingleService] 
}) 
export class SingleprojectComponent implements OnInit { 
    public single; 
    private params; 
    private singleDetails; 
    private datas; 
    private id; 

    constructor(private singleService :SingleService, 
    private _route:ActivatedRoute) { } 

    getsingle(){ 
    this.singleService.getsingle().subscribe(singleDetails => { 

     this.singleDetails = singleDetails.find(datas => datas.id === +this.params.id) 
    }); 
    } 

    ngOnInit() { 
    this.getsingle(); 
    this._route.params.subscribe(params=>{ 
    this.params = params; 


}); 
    } 

} 

Answer 1

getsingle(){ 
this.singleService.getsingle().subscribe(singleDetails => { 

    this.singleDetails = singleDetails.find(datas => datas.slug ==this.params.id); 

     this.array = singleDetails ; 

     this.index=this.array.indexOf(this.singleDetails); 
     this.nextproject= next[this.index+1]; 
     this.previousproject= next[this.index-1] 

    }); 

    } 

我得到的以前和通过使用indexof下一篇文章。它为我工作
