π Quick start
public static RedisClient cli = new RedisClient("127.0.0.1:6379,password=123,defaultDatabase=13");
cli.Serialize = obj => JsonConvert.SerializeObject(obj);
cli.Deserialize = (json, type) => JsonConvert.DeserializeObject(json, type);
cli.Notice += (s, e) => Console.WriteLine(e.Log); //print command log
cli.Set("key1", "value1");
cli.MSet("key1", "value1", "key2", "value2");
string value1 = cli.Get("key1");
string[] vals = cli.MGet("key1", "key2");
Supports strings, hashes, lists, sets, sorted sets, bitmaps, hyperloglogs, geo, streams And BloomFilter.
Parameter | Default | Explain |
---|---|---|
protocol | RESP2 | If you use RESP3, you need redis 6.0 environment |
user | <empty> | Redis server username, requires redis-server 6.0 |
password | <empty> | Redis server password |
defaultDatabase | 0 | Redis server database |
max poolsize | 100 | Connection max pool size |
min poolsize | 5 | Connection min pool size |
idleTimeout | 20000 | Idle time of elements in the connection pool (MS), suitable for connecting to remote redis server |
connectTimeout | 10000 | Connection timeout (MS) |
receiveTimeout | 10000 | Receive timeout (MS) |
sendTimeout | 10000 | Send timeout (MS) |
encoding | utf-8 | string charset |
retry | 0 | Protocol error retry execution times |
ssl | false | Enable encrypted transmission |
name | <empty> | Connection name, use client list command to view |
prefix | <empty> | The prefix of the key, all methods will have this prefix. cli.Set(prefix + "key", 111); |
exitAutoDisposePool | true | AppDomain.CurrentDomain.ProcessExit/Console.CancelKeyPress auto disposed |
subscribleReadbytes | false | Subscrible read bytes |
IPv6: [fe80::b164:55b3:4b4f:7ce6%15]:6379
//FreeRedis.DistributedCache
//services.AddSingleton<IDistributedCache>(new FreeRedis.DistributedCache(cli));
π£ Master-Slave
public static RedisClient cli = new RedisClient(
"127.0.0.1:6379,password=123,defaultDatabase=13",
"127.0.0.1:6380,password=123,defaultDatabase=13",
"127.0.0.1:6381,password=123,defaultDatabase=13"
);
var value = cli.Get("key1");
Write data at 127.0.0.1:6379; randomly read data from port 6380 or 6381.
β³ Redis Sentinel
public static RedisClient cli = new RedisClient(
"mymaster,password=123",
new [] { "192.169.1.10:26379", "192.169.1.11:26379", "192.169.1.12:26379" },
true //This variable indicates whether to use the read-write separation mode.
);
π Redis Cluster
Suppose, a Redis cluster has three master nodes (7001-7003) and three slave nodes (7004-7006), then use the following code to connect to the cluster:
public static RedisClient cli = new RedisClient(
new ConnectionStringBuilder[] { "192.168.0.2:7001", "192.168.0.2:7002", "192.168.0.2:7003" }
);
β‘ Client-side-caching
requires redis-server 6.0 and above
cli.UseClientSideCaching(new ClientSideCachingOptions
{
//Client cache capacity
Capacity = 3,
//Filtering rules, which specify which keys can be cached locally
KeyFilter = key => key.StartsWith("Interceptor"),
//Check long-term unused cache
CheckExpired = (key, dt) => DateTime.Now.Subtract(dt) > TimeSpan.FromSeconds(2)
});
π‘ Subscribe
using (cli.Subscribe("abc", ondata)) //wait .Dispose()
{
Console.ReadKey();
}
void ondata(string channel, string data) =>
Console.WriteLine($"{channel} -> {data}");
xadd + xreadgroup:
using (cli.SubscribeStream("stream_key", ondata)) //wait .Dispose()
{
Console.ReadKey();
}
void ondata(Dictionary<string, string> streamValue) =>
Console.WriteLine(JsonConvert.SerializeObject(streamValue));
// NoAck xpending
cli.XPending("stream_key", "FreeRedis__group", "-", "+", 10);
lpush + blpopοΌ
using (cli.SubscribeList("list_key", ondata)) //wait .Dispose()
{
Console.ReadKey();
}
void ondata(string listValue) =>
Console.WriteLine(listValue);
π Scripting
var r1 = cli.Eval("return {KEYS[1],KEYS[2],ARGV[1],ARGV[2]}",
new[] { "key1", "key2" }, "first", "second") as object[];
var r2 = cli.Eval("return {1,2,{3,'Hello World!'}}") as object[];
cli.Eval("return redis.call('set',KEYS[1],'bar')",
new[] { Guid.NewGuid().ToString() })
π» Pipeline
using (var pipe = cli.StartPipe())
{
pipe.IncrBy("key1", 10);
pipe.Set("key2", Null);
pipe.Get("key1");
object[] ret = pipe.EndPipe();
Console.WriteLine(ret[0] + ", " + ret[2]);
}
π° Transaction
using (var tran = cli.Multi())
{
tran.IncrBy("key1", 10);
tran.Set("key2", Null);
tran.Get("key1");
object[] ret = tran.Exec();
Console.WriteLine(ret[0] + ", " + ret[2]);
}
π― GetDatabase: switch database
using (var db = cli.GetDatabase(10))
{
db.Set("key1", 10);
var val1 = db.Get("key1");
}
π Scan
Support cluster mode
foreach (var keys in cli.Scan("*", 10, null))
{
Console.WriteLine(string.Join(", ", keys));
}
