Question

我试图抓住

\Predis\Connection\ConnectionException

在symfony应用程序中，但由于某种原因它无法正常工作。

所有涉及缓存的代码部分都在try catch块中：

   try {
                $client = new PredisClient(getenv('CACHE_SERVER'));
                $this->cache = new PredisCache($client);
            } catch (\Predis\Connection\ConnectionException | \ErrorException $e) {
                // If no redis cache available, use file cache
                $this->log->addInfo('problems with reading from redis cache, temporarily use file system cache');
            }

以及从缓存中读取时

 try {
            if ($result_cache = $this->cache->fetch($cacheid)) {
                return $result_cache;
            }
        } catch (\Predis\Connection\ConnectionException  | \ErrorException $e) {
            // forget the result and go on with database query
            $this->log->addInfo('problems with reading from redis cache, getting the result from the database');
        }

但是有时候会出现这样的错误：

Uncaught PHP Exception Predis\Connection\ConnectionException: "Error while reading line from the server. [tls://<NAME_OF_REDIS_SERVER:6380]" at /var/www/projec1/vendor/predis/predis/src/Connection/AbstractConnection.php line 155 {"exception":"[object] (Predis\\Connection\\ConnectionException(code: 0):

我想知道这个异常，因为在代码中捕获了Predis \ Connection \ ConnectionException，但是似乎在AbstractConnection.php中，尝试/捕获了上面的代码。

如果有人有主意...

问候托马斯

未捕获Predis \\ Connection \\ ConnectionException
