Playground

package main

import (
    "fmt"
    "net/http"
    "os"
    "text/template"
)

var requestTemplate string = `
{{range $i, $url := .URLs}}
{{ $url }} {{(status_code $url)}}
{{ end }}`

type Requests struct {
    URLs []string
}

func main() {
    var fns = template.FuncMap{
        "status_code": func(x string) int {
            resp, err := http.Head(x)
            if err != nil {
                return -1
            }
            return resp.StatusCode
        },
    }

    req := new(Requests)
    req.URLs = []string{"http://godoc.org", "http://stackoverflow.com", "http://linux.org"}

    tmpl := template.Must(template.New("getBatch").Funcs(fns).Parse(requestTemplate))
    err := tmpl.Execute(os.Stdout, req)
    if err != nil {
        fmt.Println(err)
    }
}

Here we use our defined function status_code to get status code of web page right from template.

Output:
