Proxyman localhost update#

Now, you can use the host local instead of localhost, which means Go will proxy your requests properly. By default, all local traffic doesnt go through HTTP Proxy Server (Proxyman), so you might not see any localhost traffic. Download Proxyman First of all, we must download the latest Proxyman at or update directly from your current version by navigating to Proxyman -> Check for Update. In your /etc/hosts, add the line such as local 127.0.0.1. Now, all traffic including calls to Host: localhost or Host: 127.0.0.1 will be properly proxied to localhost:9090. Package main import ( 'fmt' 'os' '/gophercloud/gophercloud' '/gophercloud/gophercloud/openstack' '/gophercloud/gophercloud/openstack/compute/v2/servers' ) func main ()

Imagine that you are working on something that uses the Openstack API. You need to have access to the place where the http.Client is set. Solution 1: hack the proxy setup by tweaking http.Transport Two solutions: either you have access (and are willing to) hack the source code in order to force Go to use the proxy with localhost anyway, or you can hack your /etc/hosts and use a different host. That’s a bummer since using a proxy may be the only way to debug a CLI or an application that makes network calls without logging properly. Note that the documentation forgets to mention that 127.0.0.1 (and related) are also ignored. For Python, it becomes a bit trickier often requires the app to have a flag like -cacert.īut by default, Go for localhost and 127.0.0.1 hosts (see ProxyFunc and useProxy):Īs a special case, if is “localhost” (with or without a port number), then a nil URL and nil error will be returned.

Note that HTTPS is a bit tricky and requires an additional step on macOS (settings > Proxyman CA > Generate new) but works flawlessly with any Go binary since Go supports HTTPS_PROXY by default. Since Proxyman acts like a proxy listening on 0.0.0.0:9090, I can see and replay all the HTTP calls, similarly to what you would do with the Chrome DevTools.
