Cara melaksanakan fungsi perhatian dalam PHP: 1. Cipta kod pelaksanaan lapisan kawalan "namespace AppControllerTest..." 2. Reka bentuk kod pelaksanaan lapisan perkhidmatan "namespace AppServicePtg..."; sehingga kod lapisan pergudangan Itu sahaja.
Persekitaran pengendalian artikel ini: sistem Windows 7, PHP versi 7.1, komputer DELL G3
Cara melaksanakan perkara berikut fungsi dalam php?
php redis melaksanakan fungsi berikut:
1: Fungsi berikut
2: Analisis fungsi Fungsi "Ikuti"
3: Fungsi "Ikuti" biasa mempunyai 4 nilai penting di belakangnya
Bekerja pada PC atau APP Di Pada masa yang sama, jika anda menambah beberapa konsep sosial, anda boleh mempunyai fungsi ikut dan peminat
Jika jumlah data adalah kecil, pangkalan data masih boleh menyokongnya Jika jumlah data adalah besar, lebih baik menggunakan caching .
1 Pelaksanaan lapisan kawalan
<?php namespace App\Controller\Test; use App\Controller\AbstractController; use App\Service\Ptg\TestFollowService; use Hyperf\Di\Annotation\Inject; use Hyperf\HttpServer\Annotation\Controller; use Hyperf\HttpServer\Annotation\Middleware; use Hyperf\HttpServer\Annotation\RequestMapping; /** * 测试 - 关注 * Class TestFollowController * @package App\Controller * @Controller(prefix="test") */ class TestFollowController extends AbstractController { /** * 服务层 - 关注 * @Inject() * @var TestFollowService */ protected $testFollowService; /** * 关注/取消关注 * @param Request $request * @return mixed */ public function follow(Request $request) { $type = $request->input('type', 'follow'); // 1-关注-follow 2-取消关注-remove $userId = $request->input('user_id', 0); // 我的用户ID $otherId = $request->input('other_id', 0); // 我关注的用户ID if ($userId == $otherId) { return $this->response->apiResponse(); } $this->testFollowService->follow($type, $userId, $otherId); return $this->response->apiResponse(); } /** * 我的关注/粉丝 * @param Request $request * @return mixed */ public function myFollowAndFans(Request $request) { $type = $request->input('type', 'follow'); // 1-关注-follow 2-粉丝-fans $userId = $request->input('user_id', 0); // 我的用户ID $page = $request->input('page', 1); // 页码 $limit = $request->input('limit', 10); // 每页显示条数 $res = $this->testFollowService->myFollowAndFans($userId, $type, $page, $limit); return $this->response->apiResponse($res); } } ?>
2 Pelaksanaan lapisan perkhidmatan
<?php namespace App\Service\Ptg; use App\Repository\Redis\TestFollowRedis; use App\Service\AbstractService; use Hyperf\Di\Annotation\Inject; class TestFollowService extends AbstractService { /** * 仓储层 - 关注 * @Inject() * @var TestFollowRedis */ protected $testFollowRedis; /** * 关注/取消关注 * @param string $type * @param int $userId * @param int $otherId * @return mixed */ public function follow($type = 'follow', int $userId, int $otherId) { // 关注 if ($type === 'follow') { // 先处理 mysql // TODO mysql 操作 // 然后处理 redis $this->testFollowRedis->zAddFollow($userId, $otherId); $this->testFollowRedis->zAddFans($otherId, $userId); } // 取消关注 if ($type === 'remove') { // 先处理 mysql // TODO mysql 操作 // 然后处理 redis $this->testFollowRedis->zRemFollow($userId, $otherId); $this->testFollowRedis->zRemFans($otherId, $userId); } } /** * 我的关注/粉丝 * @param int $userId 当前登录用户的ID * @param string $type 要获取的数据 * @param int $page 页码 * @param int $limit 限制条数 * @return array */ public function myFollowAndFans(int $userId, $type = 'follow', $page = 1, $limit = 10) { $start = $limit * ($page - 1); $end = $start + $limit - 1; $res = []; if ($type === 'follow') { $res = $this->testFollowRedis->zRangeFollow($userId, $start, $end); } if ($type === 'fans') { $res = $this->testFollowRedis->zRangeFans($userId, $start, $end); } return $res; } } ?>
Pelaksanaan lapisan gudang [Disyorkan: Tutorial video PHP]
<?php namespace App\Repository\Redis; class TestFollowRedis extends AbstractRedis { /** * 关注key * @var string */ private $followKey = '%u:follow'; /** * 粉丝key * @var string */ private $fansKey = '%u:fans'; /** * 前缀 */ public function initPrefix() { return 'follow:'; } /** * 增加关注 * @param $userId * @param $otherId */ public function zAddFollow($userId, $otherId) { $this->redis->zAdd(sprintf($this->prefix . $this->followKey, $userId), time(), $otherId); } /** * 取消关注 * @param $userId * @param $otherId */ public function zRemFollow($userId, $otherId) { $this->redis->zRem(sprintf($this->prefix . $this->followKey, $userId), $otherId); } /** * 我的关注 | 正序 * @param int $userId * @param int $start * @param int $end * @return array */ public function zRangeFollow(int $userId, int $start = 0, int $end = 9) { return $this->redis->zRange(sprintf($this->prefix . $this->followKey, $userId), $start, $end); } /** * 我的关注 | 倒序 * @param int $userId * @param int $start * @param int $end * @return array */ public function zRevRangeFollow(int $userId, int $start = 0, int $end = 9) { return $this->redis->zRevRange(sprintf($this->prefix . $this->followKey, $userId), $start, $end); } /** * 增加粉丝 * @param $userId * @param $otherId */ public function zAddFans($userId, $otherId) { $this->redis->zAdd(sprintf($this->prefix . $this->fansKey, $userId), time(), $otherId); } /** * 移除粉丝 * @param $userId * @param $otherId */ public function zRemFans($userId, $otherId) { $this->redis->zRem(sprintf($this->prefix . $this->fansKey, $userId), $otherId); } /** * 我的粉丝 | 正序 * @param int $userId * @param int $start * @param int $end * @return array */ public function zRangeFans(int $userId, int $start = 0, int $end = 9) { return $this->redis->zRange(sprintf($this->prefix . $this->fansKey, $userId), $start, $end); } /** * 我的粉丝 | 倒序 * @param int $userId * @param int $start * @param int $end * @return array */ public function zRevRangeFans(int $userId, int $start = 0, int $end = 9) { return $this->redis->zRevRange(sprintf($this->prefix . $this->fansKey, $userId), $start, $end); } }
