首先Windows安装redis并将redis设置成服务
注意：修改redis.windows.conf文件 设置密码requirepass和注释掉bind ip使得外网可以访问 另外服务器端口6379记得打开
引用包StackExchange.Redis
<PackageReference Include="StackExchange.Redis" Version="2.1.30" />
一、添加配置（appsettings.json）
"ConnectionStrings": {
"Redis": "XXX.XX.XX.XXX,password=******,DefaultDatabase=0"
},
二、添加服务依赖（Startup.cs）
RedisClient.redisClient.InitConnect(Configuration);
三、redis帮助类（RedisClient）
using Microsoft.Extensions.Configuration;
using Newtonsoft.Json;
using StackExchange.Redis;
using System;
using System.Collections.Generic;
using System.Text;
namespace Dw.Util.Helper
{
public class RedisClient
{
private static readonly object Locker = new object();
private ConnectionMultiplexer redisMultiplexer;
IDatabase db = null;
private static RedisClient _redisClient = null;
public static RedisClient redisClient
{
get
{
if (_redisClient == null)
{
lock (Locker)
{
if (_redisClient == null)
{
_redisClient = new RedisClient();
}
}
}
return _redisClient;
}
}
public void InitConnect(IConfiguration Configuration)
{
try
{
var RedisConnection = ConfigHelper.GetValue("ConnectionStrings:Redis");
redisMultiplexer = ConnectionMultiplexer.Connect(RedisConnection);
db = redisMultiplexer.GetDatabase();
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
redisMultiplexer = null;
db = null;
}
}
public RedisClient()
{
}
/// <summary>
/// 保存单个key value
/// </summary>
/// <param name="value">保存的值</param>
/// <param name="expiry">过期时间</param>
public bool SetStringKey(string key, string value, TimeSpan? expiry = default(TimeSpan?))
{
return db.StringSet(key, value, expiry);
}
/// <summary>
/// 获取单个key的值
/// </summary>
public RedisValue GetStringKey(string key)
{
return db.StringGet(key);
}
/// <summary>
/// 获取一个key的对象
/// </summary>
public T GetStringKey<T>(string key)
{
if (db == null)
{
return default;
}
var value = db.StringGet(key);
if (value.IsNullOrEmpty)
{
return default;
}
return JsonConvert.DeserializeObject<T>(value);
}
/// <summary>
/// 保存一个对象
/// </summary>
/// <param name="obj"></param>
public bool SetStringKey<T>(string key, T obj, TimeSpan? expiry = default(TimeSpan?))
{
if (db == null)
{
return false;
}
string json = JsonConvert.SerializeObject(obj);
return db.StringSet(key, json, expiry);
}
}
}
四、在控制器中使用
#region Redis测试
/// <summary>
/// Redis测试
/// </summary>
/// <returns></returns>
[Route("Redis")]
[HttpGet]
public ActionResult Redis()
{
var redisResult = RedisClient.redisClient.GetStringKey("myKey");
return Ok(new { code = "200", res = new { msg = redisResult.ToString() } });
}
#endregion
