如何在map [string] string中读取* redis.Client.TxPipeline.Exec（）方法的响应

I am using redis.v5. I want to read all redis keys value in one go, value of each key is hashMap i.e map[string]string. So I am using Redis transaction functionality of MULTI/EXEC. I have a function which does this, I am getting the response like this:

[hgetall x: map[VIN:POIUYTRUT4567ASWQ beaconID:1123VBG132 customerName:Amit displayLocation:waiting launge timestamp:2017-12-26T08:51:21.509Z] y: map[VIN:POIUYTRUT4567qweD beaconID:1123VBG13222 customerName:prameet displayLocation:waiting launge timestamp:2017-12-26T08:51:21.509Z]]

my function is this:

 func GetListOfValuesForKeys( keys []string,address, password string,db int) ([]map[string]string, error) {
    redisClient, err := redis.NewClient(loadRedisOptions(address, password, db))
    if err != nil {
        return nil, err
    }
    pipe := redisClient.TxPipeline()
    for _, val := range keys {
        pipe.HGetAll(val)
    }
    var data []map[string]string

    cmder, err := pipe.Exec()
    if err != nil {
        return nil, err
    }
    fmt.Printf("
|**********res %++v**************|
", cmder)

    return data, nil
}

func loadRedisOptions(address, password string, db int) *redis.Options 
{

return &redis.Options{
    Addr:     address,
    Password: password,
    DB:       db,
}
}

Now is there any inbuilt method in redis.v5 which can Unmarshal the pipe.Exec() method's response to map[string]string. pipe.Exec() method returns a slice of given below interface ([]Cmder):

    type Cmder interface {
    args() []interface{}
    arg(int) string
    name() string

    readReply(*pool.Conn) error
    setErr(error)

    readTimeout() *time.Duration

    Err() error
    fmt.Stringer
}

This is the definition of Exec:

func (c *Pipeline) Exec() ([]Cmder, error)

and Cmder implements

type Cmder interface {
    Name() string
    Args() []interface{}

    Err() error
    fmt.Stringer
    // contains filtered or unexported methods
}

and

Cmder implements fmt.Stringer which is defined as

type Stringer interface {
    String() string
}

where

Stringer is implemented by any value that has a String method, which defines the “native” format for that value. The String method is used to print values passed as an operand to any format that accepts a string or to an unformatted printer such as Print.

https://godoc.org/fmt#Stringer

Therefore,

You can access values by doing:

Cmder.String()

So what you're looking for is something like this:

cmdMap := map[string]string
cmder, err := pipe.Exec()
if err != nil {
    return nil, err
}
for cmd := range cmder {
    key := cmd.Name() // maybe use cmd.Args() to distinguish
    cmdMap[key] = cmd.String()
}
return cmdMap, nil

Let me know if this doesn't work.
