如何发出HTTP请求以从Clickhouse数据库获取数据

I'm trying to make an HTTP request to get data from clickhouse database using Go. I don't have too much experience with it and not sure how to get the returned value by the query

This is what I have:

reader := strings.NewReader("SELECT COUNT(*) FROM system.tables WHERE database = 'local' AND name = 'persons'")
request, err := http.NewRequest("GET", "http://localhost:8123", reader)
if err != nil {
    fmt.Println(err)
}

client := &http.Client{}
resp, err := client.Do(request)
if err != nil {
    fmt.Println(err)
}

fmt.Println("The answer is: ", resp.Body)

The expected output should be a number (1 means table exist and 0 means that doesn't exist) but I'm getting in resp.Body this output:

The answer is:  &{0xc4201741c0 {0 0} false <nil> 0x6a9bb0 0x6a9b20}

Any idea to get just the value of the query?

I had to add an extra line

message, _ := ioutil.ReadAll(resp.Body)

fmt.Println(string(message))

That helped me to get what I wanted.
