illuminate/pagination用在接口开发上不太好用

ontheway 更新于2022-07-14

返回了很多无用信息，我们也不需要这样的结构。

{
    "current_page": 1,
    "data": [
        {
            "id": 1,
            "openid": "abc",
            "nickname": "Lucy",
            "avatar": "http://avatar.pinxixi.com/0.jpg",
            "status": 1,
            "last_login_time": 1656553894,
            "created": 1656553894,
            "updated": 0,
            "deleted": 0
        }
    ],
    "first_page_url": "/?page=1",
    "from": 1,
    "last_page": 1,
    "last_page_url": "/?page=1",
    "links": [
        {
            "url": null,
            "label": "Previous",
            "active": false
        },
        {
            "url": "/?page=1",
            "label": "1",
            "active": true
        },
        {
            "url": null,
            "label": "Next",
            "active": false
        }
    ],
    "next_page_url": null,
    "path": "/",
    "per_page": 10,
    "prev_page_url": null,
    "to": 3,
    "total": 3
}

我们接口一般这样返回信息：

{
    "code": 0,
    "msg": "ok",
    "data": {
        "users": [
            {
                "id": 1,
            "openid": "abc",
            "nickname": "Lucy",
            "avatar": "http://avatar.pinxixi.com/0.jpg",
            "status": 1,
            "last_login_time": 1656553894,
            "created": 1656553894,
            "updated": 0,
            "deleted": 0
            }
        ],
        "page": {
            "limit": 20,
            "p": 1,
            "total": 2,
            "total_page": 1
        }
    }
}

我们现在用的框架就很简单：

$p = Request::getInt('p', 1);

$page = ['limit' => 20, 'p' => $p];

$users = User::where($where)
    ->fields('id, nickname, avatar, status, last_login_time, created, updated')
    ->order('last_login_time DESC')
    ->page($page)
    ->select();

return App::result(0, 'ok', [
    'users' => $users,
    'page' => $page
]);

拿到返回结果可以处理一下再给前端，前端也可以处理的！～

这还用说，只是很麻烦

个性化需求请自行扩展,illuminate/pagination是laravel开发组提供的

提供一个 bootstrap 解决，注册到 config/bootstrap.php 中

<?php

namespace app\bootstrap;

use Illuminate\Container\Container;
use Illuminate\Pagination\LengthAwarePaginator;
use Webman\Bootstrap;

class Paginator implements Bootstrap
{
    public static function start($worker)
    {
        // 修改分页返回的结构
        Container::getInstance()->bind(LengthAwarePaginator::class, function (Container $app, array $options) {
            return new class($options['items'], $options['total'], $options['perPage'], $options['currentPage'], $options['options']) extends LengthAwarePaginator {
                /**
                 * @inheritDoc
                 */
                public function toArray()
                {
                    return [
                        'items' => $this->items->toArray(),
                        'total' => $this->total(),
                    ];
                }
            };
        });
    }
}

直接在app/functions.php里面写一个方法就可以了：

<?php

use Illuminate\Contracts\Pagination\LengthAwarePaginator;

/**
 * Here is your custom functions.
 */

function listPage(LengthAwarePaginator $paginator)
{
    return [
        $paginator->items(),
        [
            'limit' => $paginator->perPage(),
            'p' => $paginator->currentPage(),
            'total' => $paginator->total(),
            'total_page' => $paginator->lastPage()
        ]
    ];
}

怎么使用：

<?php

namespace App\controller;

use support\Db;
use support\Request;

class User
{
    public function list(Request $request)
    {
        $p = $request->getInt('p', 1);
        $per_page = 10;

        $paginator = Db::table('user')->where('id', '>', 1)->paginate($per_page, '*', 'page', $p);
        list($users, $page) = listPage($paginator);

        return jsons(0, 'ok', [
            'users' => $users,
            'page' => $page
        ]);
    }
}
