To use Redis hmset in Golang, you first need to install the Redis client library for Go using the following command:
go get github.com/go-redis/redis/v8
Once the library is installed, you can create a new Redis client and use the HSet method to set multiple fields of a hash map at once. Here’s an example code snippet:
import "github.com/go-redis/redis/v8"
func main() {
client := redis.NewClient(&redis.Options{
Addr: "localhost:6379",
Password: "", // no password set
DB: 0, // use default DB
})
err := client.HSet(context.Background(), "myhash", map[string]interface{}{
"field1": "value1",
"field2": 123,
"field3": true,
}).Err()
if err != nil {
panic(err)
}
}
In this example, we’re setting three fields (“field1”, “field2”, and “field3”) with different data types in the “myhash” hash map. The HSet method takes a context object as its first argument, the hash map key as its second argument, and a map of field-value pairs as its third argument. If any error occurs while executing the command, it will be returned by the Err method.
