Golang:get.http(url)没有响应

http://plg1.yumenetworks.com/dynamic_preroll_playlist.vast2xml?domain=2210cZDclAme

when I call the link above from the server using http.Get I get this response, an empty XML:

<?xml version="1.0" encoding="UTF-8"?>
<VAST version="2.0">

</VAST>

But when I call it from the browser it responsed with a valid XML,also when I called the link from a local server it works.

func getXmlVast(url string) (string, error) {

        resp, err := http.Get(url)
        if err != nil {
            return "", err
        }
        defer resp.Body.Close()
        // read xml http response
        xmlData, err := ioutil.ReadAll(resp.Body)
        if err != nil {
            return "", err
        }
        return string(xmlData), nil
    }

Does anyone have an idea.

Thank you in advance

I think you get an empty response because you haven't specified the response headers type. Try to add:

resp, err := http.Get(url)
resp.Header.Add("Accept", "application/xml")
resp.Header.Add("Content-Type","application/xml; charset=utf-8")

if err != nil {
     return "", err
}

Maybe this will solve your problem.
