android-studio - 在 laravel 8 的模型中使用 Carbon diffForHumans

Question

我正在使用 laravel 8 框架作为我的 android 应用程序的后端，我想以与 instagram 显示时间相同的方式输出时间，但每次我使用 carbon diffForHumans 时，它都会显示 2 小时后，我希望它显示 1 分钟前，就在现在， 2 周前，2 小时前。这是我的模型

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Carbon\Carbon;

class News extends Model
{
    use HasFactory;

    protected $table = "news";

    protected $fillable = [
        'title',
        'image',
        'body'
    ];

    protected $casts = [
      'created_at' => 'datetime:d-m-Y',
      'updated_at' => 'datetime:d-m-Y'
    ];

    protected $appends=['published'];

    public function getPublishedAttribute(){
        
        return Carbon::createFromTimeStamp(strtotime($this->attributes['created_at']) )->diffForHumans();

    }

    
}

这是我的控制器

<?php

namespace App\Http\Controllers;

use App\News;
use Illuminate\Http\Request;

class NewsController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        $allposts = News:://get()->sortByDesc(function($query){
           // return $query->toArray(['id']);
        //})->
        all();

        return response()->json(['newsitemlist' => $allposts], 200);
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\Http\Response
     */
    public function create()
    {
        //
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @return \Illuminate\Http\Response
     */
    public function store(Request $request)
    {
        //
    }

    /**
     * Display the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function show($id)
    {
        $allposts = News::find($id);
        if (is_null($allposts)) {
            return response()->json(['message' => "News not available"], 404);
        }
        return response()->json(['newsitemlist' => $allposts], 200);
    }

    /**
     * Show the form for editing the specified resource.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function edit($id)
    {
        //
    }

    /**
     * Update the specified resource in storage.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function update(Request $request, $id)
    {
        //
    }

    /**
     * Remove the specified resource from storage.
     *
     * @param  int  $id
     * @return \Illuminate\Http\Response
     */
    public function destroy($id)
    {
        $allposts = News::find($id);
        if (is_null($allposts)) {
            return response()->json(['message' => "News not available"], 404);
        }

        $allposts->delete();

        return response()->json(['message' => "News Deleted Succesfully"], 200);
    }
}

根据Docs ，这是您修改created_at值所需要做的。它称为访问器

public function getCreatedAtAttribute($value){
    return Carbon::createFromFormat('Y-m-d H:i:s', $value)->diffForHumans();
}
