go-redis 基本操作及测试

安装

import "github.com/go-redis/redis/v7"
go mod tidy

注意：

基本操作

创建 redis 客户端

// Create the Redis client
func InitRedisClient() (*redis.Client, error) {
    client := redis.NewClient(&redis.Options{
        Addr:         "127.0.0.1:6379", // Redis addr:port
        Password:     "root",           // Password
        DB:           0,                // The serial number starts at 0, the default is 0, can not be set
        MaxRetries:   3,                // The maximum number of retries when the command fails. Default is 0, i.e. no retry
        PoolSize:     10,               // Maximum number of connections in the connection pool. Default is number of CPUs * 10
        MinIdleConns: 5,                // Minimum number of free connections
    })
    if err := client.Ping().Err(); err != nil {
        return nil, errors.Wrap(err, "ping redis error")
    }
    return client, nil
}

通过 cient.Ping() 来检查是否成功连接到了 redis 服务器.

String 操作

**

List 操作

**

Hash 操作

**

测试用例

// HashDemo:
func TestHashDemo(t *testing.T) {
    fmt.Println("------------------ Welcome to HashDemo  ----------------------")
    redisClient, err := InitRedisClientTest()
    if err != nil {
        fmt.Println("StringDemo redisClient is nil")
        return
    }
    //Init a map[string]interface{}
    userInfo := make(map[string]interface{})
    userInfo["name"] = "charles"
    userInfo["age"] = 27
    userId := "user:10001"
    hash, err := redisClient.HMSet(userId, userInfo).Result()
    if err != nil {
        fmt.Println(err)
    }
    fmt.Println(hash)
    mapOut := redisClient.HGetAll(userId).Val()
    for inx, item := range mapOut {
        fmt.Printf("%v:%v\n", inx, item)
    }
}
=== RUN   TestHashDemo
------------------ Welcome to HashDemo  ----------------------
true
name:charles
age:27
--- PASS: TestHashDemo (0.00s)
PASS
Process finished with exit code 0
