How to set timeout for http.Get() requests in Golang?

Question

I\'m making a URL fetcher in Go and have a list of URLs to fetch. I send http.Get() requests to each URL and obtain their response.

resp,fetch_e

A quick and dirty way:

http.DefaultTransport.(*http.Transport).ResponseHeaderTimeout = time.Second * 45

This is mutating global state w/o any coordination. Yet it might be possibly okay for your url fetcher. Otherwise create a private instance of http.RoundTripper:

var myTransport http.RoundTripper = &http.Transport{
        Proxy:                 http.ProxyFromEnvironment,
        ResponseHeaderTimeout: time.Second * 45,
}

var myClient = &http.Client{Transport: myTransport}

resp, err := myClient.Get(url)
...

Nothing above was tested.
