如何在Golang中做Redis（Redigo）LPOP

I need to do a simple lpop from a redis queue. In go lang If I use a blocking pop using blpop then the foll code works

reply, err := redis.Strings(conn.Do("BLPOP", key, 1))
        if err == nil {         
           fmt.Println(reply[1])

        // do something with string reply[1]

       }

But I do not want to block. I just need to end when the queue is empty. So how can I do that If I do redis.Strings(conn.Do("LPOP", key)) ie change BLPOP to LPOP and I get a redigo error

ERROR = redigo: unexpected type for Strings, got type []uint8 

The BLPOP command returns a two element array where the first element is the key and the second value is the popped element.

The LPOP command returns the popped element.

Use the String helper function to get the popped element:

reply, err := redis.String(conn.Do("LPOP", key))
        if err == nil {         
           fmt.Println(reply)
        // do something with string reply
       }

I can get the lpop'ed value using redis.String()

so this works

reply, err := redis.String(conn.Do("LPOP", key))
    if err == nil { 
     fmt.Printf("REPLY= %s
", reply)
      //do something
