Do Method

Do is a universal command interaction method that executes synchronous instructions by sending corresponding Redis API commands to the Redis Server to utilize the Redis Server services. The biggest feature of the Do method is its strong extensibility by interacting with the server using Redis commands, which can implement other commands not provided by the Redis operation methods. Usage example:

package main

import (
    "fmt"
    "github.com/gogf/gf/v2/frame/g"
    "github.com/gogf/gf/v2/os/gctx"
)

func main() {
    var (
        ctx = gctx.New()
    )
    v, _ := g.Redis().Do(ctx, "SET", "k", "v")
    fmt.Println(v.String())
}

Automatic Serialization/Deserialization

When the given parameters are map, slice, or struct, gredis internally supports automatic json serialization and can use the conversion functions of gvar.Var for deserialization when reading data.

map Access

package main

import (
    "fmt"
    "github.com/gogf/gf/v2/container/gvar"
    "github.com/gogf/gf/v2/frame/g"
    "github.com/gogf/gf/v2/os/gctx"
)

func main() {
    var (
        ctx = gctx.New()
        err    error
        result *gvar.Var
        key    = "user"
        data   = g.Map{
            "id":   10000,
            "name": "john",
        }
    )
    _, err = g.Redis().Do(ctx, "SET", key, data)
    if err != nil {
        panic(err)
    }
    result, err = g.Redis().Do(ctx,"GET", key)
    if err != nil {
        panic(err)
    }
    fmt.Println(result.Map())
}

struct Access

package main

import (
    "fmt"
    "github.com/gogf/gf/v2/container/gvar"
    "github.com/gogf/gf/v2/frame/g"
    "github.com/gogf/gf/v2/os/gctx"
)

func main() {
    type User struct {
        Id   int
        Name string
    }

    var (
        ctx = gctx.New()
        err    error
        result *gvar.Var
        key    = "user"
        user   = g.Map{
            "id":   10000,
            "name": "john",
        }
    )

    _, err = g.Redis().Do(ctx, "SET", key, user)
    if err != nil {
        panic(err)
    }
    result, err = g.Redis().Do(ctx, "GET", key)
    if err != nil {
        panic(err)
    }

    var user2 *User
    if err = result.Struct(&user2); err != nil {
        panic(err)
    }
    fmt.Println(user2.Id, user2.Name)
}
