Redis client for Golang [](https://travis-ci.org/go-redis/redis)
|
|
=======================
|
|
|
|
Supports:
|
|
|
|
- Redis 3 commands except QUIT, MONITOR, SLOWLOG and SYNC.
|
|
- Pub/Sub.
|
|
- Transactions.
|
|
- Pipelines.
|
|
- Connection pool. Client can be safely used from multiple goroutines.
|
|
- Timeouts.
|
|
- [Redis Sentinel](http://godoc.org/gopkg.in/redis.v3#NewFailoverClient).
|
|
- [Redis Cluster](http://godoc.org/gopkg.in/redis.v3#NewClusterClient).

Installation
|

------------
|

Install:
|
|
|
|
go get gopkg.in/redis.v3
|
|
|
|
Quickstart
|
|
----------
|
|
|
|
```go
|
|
func ExampleNewClient() {
|
|
client := redis.NewClient(&redis.Options{
|
|
Addr: "localhost:6379",
|
|
Password: "", // no password set
|
|
DB: 0, // use default DB
|
|
})
|
|
|
|
pong, err := client.Ping().Result()
|
|
fmt.Println(pong, err)
|
|
// Output: PONG <nil>
|
|
}
|
|
|
|
func ExampleClient() {
|
|
err := client.Set("key", "value", 0).Err()
|
|
if err != nil {
|
|
panic(err)
|
|
}
|
|
|
|
val, err := client.Get("key").Result()
|
|
if err != nil {
|
|
panic(err)
|
|
}
|
|
fmt.Println("key", val)
|
|
|
|
val2, err := client.Get("key2").Result()
|
|
if err == redis.Nil {
|
|
fmt.Println("key2 does not exists")
|
|
} else if err != nil {
|
|
panic(err)
|
|
} else {
|
|
fmt.Println("key2", val2)
|
|
}
|
|
// Output: key value
|
|
// key2 does not exists
|
|
}
|
|
```

Look and feel

|
-------------
|
|
|
|
Some corner cases:
|
|
|
|
SET key value EX 10 NX
|
|
set, err := client.SetNX("key", "value", 10*time.Second).Result()
|
|
|
|
SORT list LIMIT 0 2 ASC
|
|
vals, err := client.Sort("list", redis.Sort{Offset: 0, Count: 2, Order: "ASC"}).Result()
|
|
|
|
ZRANGEBYSCORE zset -inf +inf WITHSCORES LIMIT 0 2
|
|
vals, err := client.ZRangeByScoreWithScores("zset", redis.ZRangeByScore{
|
|
Min: "-inf",
|
|
Max: "+inf",
|
|
Offset: 0,
|
|
Count: 2,
|
|
}).Result()
|
|
|
|
ZINTERSTORE out 2 zset1 zset2 WEIGHTS 2 3 AGGREGATE SUM
|
|
vals, err := client.ZInterStore("out", redis.ZStore{Weights: []int64{2, 3}}, "zset1", "zset2").Result()
|
|
|
|
EVAL "return {KEYS[1],ARGV[1]}" 1 "key" "hello"
|
|
vals, err := client.Eval("return {KEYS[1],ARGV[1]}", []string{"key"}, []string{"hello"}).Result()
