如何在Golang中为http.Get（）请求设置超时？

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_err := http.Get(url)

How can I set a custom timeout for each Get request? (The default time is very long and that makes my fetcher really slow.) I want my fetcher to have a timeout of around 40-45 seconds after which it should return "request timed out" and move on to the next URL.

How can I achieve this?

Answer 1

Apparently in Go 1.3 http.Client has Timeout field

timeout := time.Duration(5 * time.Second)
client := http.Client{
    Timeout: timeout,
}
client.Get(url)

That's done the trick for me.
