我有一个流明api在我的服务器上,它工作得很好。实际上,这个api每秒钟都会从另一台服务器调用一次,更新库存率并存储到redis中。在这个api中,我比较从redis接收的数据(请求体)和存储的数据,更新当前值和以前值的差异率作为响应,并且我将在redis中发送当前日期时间来显示股票价格的最后一次更新时间。我的流明api中有以下代码,

use Illuminate\Support\Facades\Redis;
public function updatebaserate(Request $request)
{
        $request_data = array();
        parse_str($request, $request_data);
        if (app('redis')->get("BaseRates")) {
            if(json_decode(app('redis')->get("BaseRates"),true) === json_decode($request->getContent(), true)){
                $this->createrates();
                return app('redis')->get("BaseRatesUpdated");
            }else{
                $receivedrates = json_decode($request->getContent(), true);
                $rate_valid = true;
                if($rate_valid){
                    app('redis')->set("BaseRatesUpdated", Carbon::createFromFormat('d-m-Y H:i:s', date('d-m-Y H:i:s')));
                    app('redis')->set("BaseRates", $request->getContent());
                }
            }
        } else {
            app('redis')->set("BaseRates", $request->getContent());
            app('redis')->set("BaseRatesUpdated", Carbon::createFromFormat('d-m-Y H:i:s', date('d-m-Y H:i:s')));
        }
        $this->createrates();
        return app('redis')->get("BaseRatesUpdated");
}

每秒钟连续工作一次的redis操作的get和set 2api请求将从另一个服务器调用。是否会引起任何问题。在我的lumen.env设置中

BROADCAST_DRIVER=redis

CACHE_DRIVER=redis
QUEUE_DRIVER=redis

REDIS_HOST=127.0.0.1
REDIS_PORT=6379

在服务器redis info中显示以下详细信息,

redis中是否存在每秒连续读写密钥的问题。我还设置了redis超时值

127.0.0.1:6379> config get timeout
1) "timeout"
2) "100"

在redis的lumen api中是否有打开和关闭连接的方法。我经常收到错误日志中的错误,如

[2020-03-17 17:17:29] production.ERROR: Predis\Connection\ConnectionException: Connection timed out [tcp://127.0.0.1:6379] in /home/public_html/winapi/vendor/predis/predis/src/Connection/AbstractConnection.php:155

请帮助任何人解决这个问题。

请尝试更改redis timeout 价值 /etc/redis/redis.conf 一些非零值。这可以解决你的问题。
