laravel自定义缓存memcache（自带memcached，windows不支持）

Posted 2021-01-30 winstonsias

1、首先弄清楚memcache和memcached的区别（自行搜索）

2、安装memcache服务端（参照https://www.cnblogs.com/winstonsias/p/10190745.html）及php扩展（参照https://www.cnblogs.com/winstonsias/p/10193781.html）

3、添加服务提供类 MemcacheServiceProvider ，记得在app.php配置文件添加提供者注册

 1   namespace App\\Providers;
 2 
 3     use Cache;
 4     use App\\Extensions\\MemcacheStore;
 5     use Illuminate\\Support\\ServiceProvider;
 6 
 7     class MemcacheServiceProvider extends ServiceProvider
 8     {
 9         public function boot()
10         {
11             Cache::extend(\'memcache\', function ($app) {
12                 return Cache::repository(new MemcacheStore($app[\'memcache.connector\']));
13             });
14         }
15 
16         public function register()
17         {
18             //注册memcache连接的单例
19             $this->app->singleton(\'memcache.connector\', function ($app) {
20                 $config = $app[\'config\']["cache.stores.memcache"];
21                 $servers = $config[\'servers\'][0];
22                 return memcache_connect($servers[\'host\'], $servers[\'port\']);
23             });
24         }
25 
26 
27     }

4、完善存储类MemcacheStore（可在app添加Extensions文件夹存放）

 1  namespace App\\Extensions;
 2     class MemcacheStore implements \\Illuminate\\Contracts\\Cache\\Store
 3     {
 4         //memcache资源
 5         protected $memcache_conn;
 6         public  function __construct($conn)
 7         {
 8             $this->memcache_conn=$conn;
 9         }
10 
11         public function __destruct()
12         {
13             // TODO: Implement __destruct() method.
14             $this->memcache_conn=null;//释放资源
15         }
16 
17         public function get($key)
18         {
19             return $this->memcache_conn->get($key);
20         }
21 
22         public function put($key, $value, $minutes)
23         {
24         }
25 
26         public function increment($key, $value = 1)
27         {
28         }
29 
30         public function decrement($key, $value = 1)
31         {
32         }
33 
34         public function forever($key, $value)
35         {
36         }
37 
38         public function forget($key)
39         {
40         }
41 
42         public function flush()
43         {
44         }
45 
46         public function getPrefix()
47         {
48         }
49 
50         /**
51          * Retrieve multiple items from the cache by key.
52          *
53          * Items not found in the cache will have a null value.
54          *
55          * @param  array $keys
56          * @return array
57          */
58         public function many(array $keys)
59         {
60             // TODO: Implement many() method.
61         }
62 
63         /**
64          * Store multiple items in the cache for a given number of minutes.
65          *
66          * @param  array $values
67          * @param  int $minutes
68          * @return void
69          */
70         public function putMany(array $values, $minutes)
71         {
72             // TODO: Implement putMany() method.
73         }
74     }

5、在cache.php配置文件中添加自定义缓存store

 1  /**
 2          * 自定义memcache，不用memcached by winston
 3          */
 4         \'memcache\' => [
 5             \'driver\' => \'memcache\',
 6             \'servers\' => [
 7                 [
 8                     \'host\' => env(\'MEMCACHED_HOST\', \'xx.xx.xx.xx\'),
 9                     \'port\' => env(\'MEMCACHED_PORT\', 11211),
10                     \'weight\' => 100,
11                 ],
12             ],
13         ],

 

6、在控制器中使用

1  $val=Cache::store(\'memcache\')->get(\'xxxx\');
