如何使用 Laravel 和 Predis 从 JSON 输出中更新或删除记录

Question

几个月前我开始使用 Laravel，我想实现 Redis。

从 $test 更新或删除 1 条或多条记录的最佳方式和方法是什么。

    $allarticles = Article::all();
    $client = Redis::connection();
    $client->set('articles', $allarticles->toJson() );
    $test = $client->set('articles');

输出：

    [{
        "id":1,"title":"xQeMKGefAW","content":"44cuxAqVDS@gmail.com","created_at":null,"updated_at":null},{
        "id":2,"title":"a5wpRVRBNZ","content":"SsH9U5kF32@gmail.com","created_at":null,"updated_at":null},{
        "id":3,"title":"QF5xhsMh7d","content":"8erXnIojAM@gmail.com","created_at":null,"updated_at":null},{
        "id":4,"title":"gQVbDNbcmD","content":"27feouH6vc@gmail.com","created_at":null,"updated_at":null},{
        "id":5,"title":"FsOnoABBTg","content":"2qNutidwKZ@gmail.com","created_at":null,"updated_at":null},{
        "id":6,"title":"89sS4UASJl","content":"cQku7DBKSB@gmail.com","created_at":null,"updated_at":null},{
        "id":7,"title":"gpT3hO43V1","content":"EhzyEylbgw@gmail.com","created_at":null,"updated_at":null},{
        "id":8,"title":"1DKvbBn7yV","content":"0cSAxi9if3@gmail.com","created_at":null,"updated_at":null},{
        "id":9,"title":"pRr2LgzezC","content":"Aam0uuWLlF@gmail.com","created_at":null,"updated_at":null}

答案：

$allarticles = Article::all()->keyBy('id'); $client = Redis::connection();
$newarray = array(); 
foreach ( $allarticles->toArray() as $key => $value ){
    $newarray[$key] = json_encode($value); } $client->hmset('testtest', $newarray);
    $qwerty = $client->HGETALL('testtest'); 
    print_r($qwerty);
}

Answer 1

不是将整个 json 存储为字符串，而是使用 hmset 命令将它们存储在 hashmap 中，id 是成员，json 的其余部分是值。

http://redis.io/commands#hash

设置json：

hmset articles 1 {"title":"xQeMKGefAW","content":"44cuxAqVDS@gmail.com","created_at":null,"updated_at":null} 2 {"title":"xQeMKGefAW","content":"44cuxAqVDS@gmail.com","created_at":null,"updated_at":null} and so on

要检索整个 json：

hgetall articles

要更新一个或多个值，请使用 HMSET

要删除一个或多个值，请使用 HDEL

希望这会有所帮助。
