Partage RedisRepository et correction d'erreurs

1. Écrit avant

Après avoir obtenu mon diplôme et travaillé, j'ai finalement pu rentrer chez moi aujourd'hui, j'ai repensé à certains des contenus que j'ai réalisés au cours des six derniers mois, et j'ai toujours l'impression que c'est le cas. toujours à un niveau aussi basique, et je résous toujours divers problèmes dans le processus de résolution de problèmes, j'ai moins d'idées innovantes et je m'appuie davantage sur la recherche. Je ne veux pas faire un résumé de 2016. J'espère qu'en 2017 je pourrai apprendre plus de technologies que j'aime, lire plus de code open source, apprendre plus d'idées de conception et de codage, et mettre à jour ma compréhension du code au cours des deux dernières années. années. .

Ce partage vise principalement à combler les lacunes de mon précédent RedisRepository.

En raison d'une lecture insuffisante du document StackExchange.Redis, j'ai partagé une erreur dans le RedisRepository il y a six mois. Voici mes principales erreurs :

Erreur 1, il n'y a pas d'objet de connexion Redis Singleton ConnectionMultiplexer, et j'ai naïvement pensé que verrouiller l'objet singleton limiterait les performances de Redis dans des situations concurrentes.

Erreur 2. Dans la situation maître-esclave, je pensais que lorsqu'une commutation manuelle se produisait, nous devions nous abonner à l'événement de commutation et modifier dynamiquement le point de terminaison pointé par l'objet de connexion après que l'événement se soit produit.

Lorsque j'ai relu attentivement le document, j'ai réalisé mon erreur. Il s'agit d'une correction tardive, mais mon propre référentiel estime qu'il y a encore de nombreuses lacunes, j'ai donc vraiment besoin de conseils et de suggestions.

Correction 1. Le coût de création d'un objet de connexion Redis est très élevé et le verrouillage singleton n'affectera pas les performances de Redis, car l'objet de connexion n'attend pas pendant la requête réseau.

Correction 2, lorsque Redis est maître-esclave, après que la sentinelle ait changé la relation maître-esclave, StackExchange.Redis identifiera le nouveau maître-esclave pour nous sans aucune opération de notre part.

J'ai encore deux questions pour l'instant.

Question 1, il n'y a pas de résultat clair après lecture du document. Lorsque la séparation lecture-écriture maître-esclave est effectuée, lorsque nous ajoutons plusieurs nœuds à la collection de points de terminaison, la séparation lecture-écriture se produira automatiquement ? Ou devons-nous spécifier CommandFlags.PreferSlave dans la méthode de lecture de la commande ? Je pense que c'est ce dernier ? Je précise donc PreferSlave dans toutes mes méthodes de lecture. Que disent les pilotes vétérans ?

Question 2. J'utilise LuaScript.Prepare(lua) puis je le charge. L'exécution de lua n'a toujours aucun effet, et LuaScript.GetCachedScriptCount() vaut 0. Cependant, si j'utilise directement ScriptEvaluateAsync, il est facile de le faire. utiliser.Ancien Si le conducteur a un bon exemple, j'espère que le conducteur expérimenté pourra donner des conseils ou le partager.

2. Structure du code, pour référence seulement

La structure est à peu près comme ceci Toutes les classes sous RedisAsyncHelper sont des classes partielles et leur nom de classe est RedisHelper. . Ils ont implémenté conjointement l'interface IRedisHelper et ont laissé des commentaires détaillés.

La structure des répertoires de la version synchrone et de la version asynchrone est la même.

3. Phase préparatoire

Deux classes d'assistance dans CommonHelper :

RedisInnerTypeHelper.cs

using StackExchange.Redis;
using System.Collections.Generic;
using System.Linq;
namespace Fantasy.RedisRepository.CommonHelper
{
 internal class RedisInnerTypeHelper
 {
 public static List<T> RedisValuesToGenericList<T>(RedisValue[] redisValues)
 {
  var result = new List<T>();
  redisValues.ToList().ForEach(r => result.Add(SerializeHelper.Deserialize<T>(r)));
  return result;
 }
 public static RedisValue[] GenericListToRedisValues<T>(List<T> values)
 {
  var redisValues = new List<RedisValue>();
  values.ForEach(v => redisValues.Add(SerializeHelper.Serialize(values)));
  return redisValues.ToArray();
 }
 public static RedisKey[] GenericListToRedisKeys(List<string> keys)
 {
  var redisKeys = new List<RedisKey>();
  keys.ForEach(k => redisKeys.Add(k));
  return redisKeys.ToArray();
 }
 }
}

SerializeHelper.cs

using System.IO;
using System.Runtime.Serialization.Formatters.Binary;
namespace Fantasy.RedisRepository.CommonHelper
{
 internal static class SerializeHelper
 {
 /// <summary>

  }
  BinaryFormatter binaryFormatter = new BinaryFormatter();
  using (MemoryStream memoryStream = new MemoryStream())
  {
  binaryFormatter.Serialize(memoryStream, o);
  byte[] objectDataAsStream = memoryStream.ToArray();
  return objectDataAsStream;
  }
 }
 /// <summary>

 internal static T Deserialize<T>(byte[] stream)
 {

  }
  BinaryFormatter binaryFormatter = new BinaryFormatter();
  using (MemoryStream memoryStream = new MemoryStream(stream))
  {
  T result = (T)binaryFormatter.Deserialize(memoryStream);
  return result;
  }
 }
 }
}

Configuration classe dans Config :
ConfigHelper.cs

using System;
using System.Configuration;
namespace Fantasy.RedisRepository.Config
{
 internal class ConfigHelper
 {
 internal static T Get<T>(string appSettingsKey, T defaultValue)
 {
  string text = ConfigurationManager.AppSettings[appSettingsKey];
  if (string.IsNullOrWhiteSpace(text))
  return defaultValue;
  try

  var value = Convert.ChangeType(text, typeof(T));
  return (T)value;
  }
  catch
  {
  return defaultValue;
  }
 }
 }
}

RedisClientConfig.cs

namespace Fantasy.RedisRepository.Config

 private static int _slavePort = ConfigHelper.Get("SlavePort", 6381);
 /// <summary>

 /// </summary>
 public static int SlavePort

 private static string _auth = ConfigHelper.Get("RedisAuth", "fantasy..");
 /// <summary>

 public static string RedisAuth

  set { _auth = value; }
 }
 private static int _defaultDatabase = ConfigHelper.Get("RedisDataBase", 0);
 /// <summary>

 /// </summary>
 public static int DefaultDatabase
 {
  get { return _defaultDatabase; }
  set { _defaultDatabase = value; }
 }
 private static int _connectTimeout = 10000;
 public static int ConnectTimeout
 {
  get { return _connectTimeout; }
  set { _connectTimeout = value; }
 }
 private static int _connectRetry = 3;
 public static int ConnectRetry
 {

  set { _connectRetry = value; }
 }
 private static bool _preserveAsyncOrder = false;
 public static bool PreserveAsyncOrder
 {
  get { return _preserveAsyncOrder; }
  set { _preserveAsyncOrder = value; }
 }
 }
}

RedisConnection.cs

using Fantasy.RedisRepository.Config;
using StackExchange.Redis;
namespace Fantasy.RedisRepository
{
 /// <summary>
 /// Redis连接类
 /// </summary>
 public static class RedisConnection
 {
 private static ConnectionMultiplexer _connection;
 private static readonly object SyncObject = new object();
 /// <summary>
 /// redis连接对象，单例加锁不影响性能
 /// </summary>
 public static ConnectionMultiplexer GenerateConnection
 {
  get
  {
  if (_connection == null || !_connection.IsConnected)
  {
   lock (SyncObject)
   {
   var configurationOptions = new ConfigurationOptions()
   {
    Password = RedisClientConfig.RedisAuth,
    EndPoints =
    {
{RedisClientConfig.Server, RedisClientConfig.Port},
    {RedisClientConfig.SlaveServer, RedisClientConfig.SlavePort}
    }
   };
   _connection = ConnectionMultiplexer.Connect(configurationOptions);
   }
  }
  return _connection;

RedisLuaHelper.cs Je prévois d'installer des scripts Lua fonctionnels ici. Les paramètres externes tels que la clé sont toujours transmis. Ceci est incomplet et n'est qu'un exemple.

using StackExchange.Redis;
using System.Threading.Tasks;
namespace Fantasy.RedisRepository.RedisHelpers
{
 internal partial class RedisHelper
 {
 public async Task<RedisResult> LuaMutilGetHash()
 {
  string lua = @"local result={}
  for i, v in ipairs(KEYS) do
   result[i] = redis.call(&#39;hgetall&#39;,v) 
  end
  return result";
  var res = await _client.ScriptEvaluateAsync(lua, new RedisKey[] { "people:1", "people:2", "people:3" });
  var res1= LuaScript.GetCachedScriptCount();
  return res;
 }
 }
}

Concernant l'encapsulation de Transcation, je n'ai personnellement aucune bonne méthode, je propose une telle méthode

public async Task<bool> DoInTranscationAsync(Action<ITransaction> runOperations)
 {
  var tran = RedisConnection.GenerateConnection.GetDatabase().CreateTransaction();
  runOperations(tran);
  return await tran.ExecuteAsync();
 }

RedisFactory.cs

using Fantasy.RedisRepository.RedisHelpers;

 /// <summary>
 /// 外部访问redis入口，暂时只暴露异步方法
 /// </summary>
 /// <returns></returns>
 public static IRedisHelper CreateRedisRepository()
 {
  return new RedisHelper();
 }
 }
}
