. Net core uses redis Based on StackExchange. Redis, stackexchange. redis

. Net core using redis Based on StackExchange. Redis tutorial, details are as follows

1. Add a reference package

StackExchange. Redis
Microsoft. Extensions. Configuration

2. modify the configuration file appsettings. json

{ "RedisConfig": {  "Redis_Default": {   "Connection": "127.0.0.1: 6379",   "InstanceName": "Redis1: "  },  "Redis_6": {   "Connection": "127.0.0.1: 6379",   "DefaultDatabase": 6,   "InstanceName": "Redis2: "  } }}

3. Simple Encapsulation
RedisClient. cs class

Public class RedisClient: IDisposable {private IConfigurationRoot _ config; private ConcurrentDictionary <string, ConnectionMultiplexer> _ connections; public RedisClient (IConfigurationRoot config) {_ config = config; _ connections = new ConcurrentDictionary <string, ConnectionMultiplexer> ();} /// <summary> /// obtain ConnectionMultiplexer // </summary> /// <param name = "redisConfig"> RedisConfig configuration file </param >/// <Returns> </returns> private ConnectionMultiplexer GetConnect (IConfigurationSection redisConfig) {var redisInstanceName = redisConfig ["InstanceName"]; var connStr = redisConfig ["Connection"]; return _ connections. getOrAdd (redisInstanceName, p => ConnectionMultiplexer. connect (connStr ));} /// <summary> /// check the input parameters /// </summary> /// <param name = "configName"> RedisConfig configuration file Redis_Default/Redis _ 6. Name </param> /// <returns> </returns> private IConfigurationSection CheckeConfig (string configName) {IConfigurationSection redisConfig = _ config. getSection ("RedisConfig "). getSection (configName); if (redisConfig = null) {throw new ArgumentNullException ($ "{configName} cannot find the corresponding RedisConfig configuration! ");} Var redisInstanceName = redisConfig [" InstanceName "]; var connStr = redisConfig [" Connection "]; if (string. isNullOrEmpty (redisInstanceName) {throw new ArgumentNullException ($ "{configName} cannot find the corresponding InstanceName");} if (string. isNullOrEmpty (connStr) {throw new ArgumentNullException ($ "{configName} cannot find the corresponding Connection");} return redisConfig ;} /// <summary> /// obtain the database /// </summary> /// <param name = "c OnfigName "> </param> // <param name =" db "> default value: 0: db configuration with priority code, in config, configure </param> /// <returns> </returns> public IDatabase GetDatabase (string configName = null, int? Db = null) {int defaultDb = 0; IConfigurationSection redisConfig = CheckeConfig (configName); if (db. hasValue) {defaultDb = db. value;} else {var strDefalutDatabase = redisConfig ["DefaultDatabase"]; if (! String. isNullOrEmpty (strDefalutDatabase) & Int32.TryParse (strDefalutDatabase, out var intDefaultDatabase) {defaultDb = intdefadatabase database;} return GetConnect (redisConfig ). getDatabase (defaultDb);} public IServer GetServer (string configName = null, int endPointsIndex = 0) {IConfigurationSection redisConfig = CheckeConfig (configName); var connStr = redisConfig ["Connection"]; var confOption = C OnfigurationOptions. parse (string) connStr); return GetConnect (redisConfig ). getServer (confOption. endPoints [endPointsIndex]);} public ISubscriber GetSubscriber (string configName = null) {IConfigurationSection redisConfig = CheckeConfig (configName); return GetConnect (redisConfig ). getSubscriber ();} public void Dispose () {if (_ connections! = Null & _ connections. Count> 0) {foreach (var item in _ connections. Values) {item. Close ();}}}}

Because the RedisClient uses ConcurrentDictionary
Therefore, with the RedisClientSingleton. cs class

public class RedisClientSingleton{ private static RedisClient _redisClinet; private RedisClientSingleton() { } private static object _lockObj = new object(); public static RedisClient GetInstance(IConfigurationRoot config) {  if (_redisClinet == null)  {   lock (_lockObj)   {    if (_redisClinet == null)    {     _redisClinet = new RedisClient(config);    }   }  }  return _redisClinet; }}

Iv. Test

1. Console Program

1) create a Controller Program
2) Add a reference package
Microsoft. Extensions. Configuration
Microsoft. Extensions. Configuration. Json
3) add etettings. json

Add the following

"RedisConfig": { "Redis_Default": {  "Connection": "127.0.0.1:6379",   "InstanceName": "Redis1:" }, "Redis_6": {  "Connection": "127.0.0.1:6379",  "DefaultDatabase": 6,  "InstanceName": "Redis2:" } }

4) modify the Program class

① Add and reference using Microsoft. Extensions. Configuration;
② Modify Main

static void Main(string[] args) { 　　var builder = new ConfigurationBuilder()    .SetBasePath(Directory.GetCurrentDirectory())    .AddJsonFile("appsettings.json");   IConfigurationRoot configuration = builder.Build(); 　　var redisClient = RedisClientSingleton.GetInstance(configuration); 　　   var redisDatabase = redisClient.GetDatabase("Redis_Default"); 　　redisDatabase.StringSet("TestStrKey", "TestStrValue");} 

③ After running, you can see

2. web programs

① Create a core mvc Project
② Modify the Startup. cs File
Modify ConfigureServices Functions

public void ConfigureServices(IServiceCollection services){ ... services.AddSingleton(Configuration); ...}

The Configuration here is public IConfigurationRoot Configuration {get ;}

③ Create a TestController
Modify the constructor
SimpleRedisExt _ redisExt;

public TokenTranslateController(IConfigurationRoot config)//, IConfigurationRoot config){ _config = config; IDatabase redisDataBase = RedisClientSingleton.GetInstance(_config).GetDatabase("Redis_Default");} public string Post(string value){ redisDataBase.StringSet("TestMvcRedis", value);}

④ Run value = tew.vcredisvalue and get

As you write, it is rough.
