ara

Package ara provides a dialer with customizable resolver.

It can be used with http.Client and http.Transport to alter host lookups. For example, with a custom resolver that maps google.com to 127.0.0.1, you can get httpClient.Get("http://google.com") to connect the localhost.

Example

server := &http.Server{
    Addr: "127.0.0.1:80",
    Handler: http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
        w.Write([]byte("Alo?"))
    })
}
go server.ListenAndServe()
client := ara.NewClient(ara.NewCustomResolver(map[string][]string{"example.com": {"127.0.0.1"}}))
res, _ := client.Get("http://example.com")
body, _ := ioutil.ReadAll(res.Body)
fmt.Println(string(body))
// Output: Alo?
