http - Go doing a GET request and building the Querystring

Question

I am pretty new to Go and don't quite understand everything as yet. In many of the modern languages Node.js, Angular, jQuery, PHP you can do a GET request with additional query string parameters.

Doing this in Go isn't quite a simple as it seems, and I can't really figure it out as yet. I really don't want to have to concatenate a string for each of the requests I want to do.

Here is the sample script:

package main

import (
    "fmt"
    "io/ioutil"
    "net/http"
)

func main() {
    client := &http.Client{}

    req, _ := http.NewRequest("GET", "http://api.themoviedb.org/3/tv/popular", nil)
    req.Header.Add("Accept", "application/json")
    resp, err := client.Do(req)

    if err != nil {
        fmt.Println("Errored when sending request to the server")
        return
    }

    defer resp.Body.Close()
    resp_body, _ := ioutil.ReadAll(resp.Body)

    fmt.Println(resp.Status)
    fmt.Println(string(resp_body))
}

In this example you can see there is a URL, which requires a GET variable of api_key with your api key as the value. The problem being that this becomes hard coded in the form of:

req, _ := http.NewRequest("GET", "http://api.themoviedb.org/3/tv/popular?api_key=mySuperAwesomeApiKey", nil)

Is there a way to build this query string dynamically?? At the moment I will need to assemble the URL prior to this step in order to get a valid response.
