go-httpclient

requires Go 1.1+ as of v0.4.0 the API has been completely re-written for Go 1.1 (for a Go 1.0.x compatible release see 1adef50)

Provides an HTTP Transport that implements the RoundTripper interface and can be used as a built in replacement for the standard library's, providing:

• connection timeouts
• request timeouts

This is a thin wrapper around http.Transport that sets dial timeouts and uses Go's internal timer scheduler to call the Go 1.1+ CancelRequest() API.

Example

transport := &httpclient.Transport{
    ConnectTimeout:        1*time.Second,
    RequestTimeout:        10*time.Second,
    ResponseHeaderTimeout: 5*time.Second,
}
defer transport.Close()

client := &http.Client{Transport: transport}
req, _ := http.NewRequest("GET", "http://127.0.0.1/test", nil)
resp, err := client.Do(req)
if err != nil {
    return err
}
defer resp.Body.Close()

Note: you will want to re-use a single client object rather than creating one for each request, otherwise you will end up leaking connections.
