I have env variable set for http_proxy, but with another call, I like to bypass proxy and use direct connection to destination server instead.
Is there any way I can do that in Go lang?
Thanks.

Just don't use the http.DefaultTransport: See golang.org/pkg/net/http/#RoundTripperVolker– Volker2017-05-31 17:49:54 +00:00Commented May 31, 2017 at 17:49

As @Volker mentioned, you can either:
- Use your own
RoundTripperinstead of theDefaultTransport - Modify
DefaultTransport.Proxyto return nil for the request in question - If the call you want to ignore proxies with is to a specific host, and you always want to ignore proxy for calls to that host, add the host to the
NO_PROXYenvironment variable

this is what I did:
var defaultTransport http.RoundTripper = &http.Transport{
Proxy: nil,
DialContext: (&net.Dialer{
Timeout: 10 * time.Second,
KeepAlive: 30 * time.Second,
DualStack: true,
}).DialContext,
MaxIdleConns: 30,
IdleConnTimeout: 90 * time.Second,
TLSHandshakeTimeout: 15 * time.Second,
ExpectContinueTimeout: 1 * time.Second,
}
client := &http.Client{Transport: defaultTransport}

I had that problem with a corporate proxy, even disabled the proxy url it was using it this was my solution
// reset proxy in http RoundTripper
var defaultTransport http.RoundTripper = &http.Transport{Proxy: nil}
client := &http.Client{Transport: defaultTransport}
