Use proxy with Volley - Githubissues

Good afternoon. Tell me how to login to the proxy

            return (HttpURLConnection) url.openConnection(new Proxy(Proxy.Type.HTTP, InetSocketAddress.createUnresolved(host_, Integer.parseInt(port_))));
        }

    public static void showIpAddress(Context context) {
        if (mRequestQueue == null)
                mRequestQueue = Volley.newRequestQueue(context, (!proxy.isEmpty() ? new ProxiedHurlStack() : null));
        AlertDialog.Builder alert = new AlertDialog.Builder(context);
        mRequestQueue.add(new StringRequest(Request.Method.GET, URL, new Response.Listener<String>() {
            @Override
            public void onResponse(String response) {
                alert.setTitle("Ok");
                try {
                    JSONObject jsonObject = new JSONObject(response);
                    alert.setMessage("My IP Address is = " + jsonObject.getString("ip"));
                } catch (JSONException e) {
                    alert.setMessage("JSON Exception = " + e.getMessage());
                    e.printStackTrace();
                }
                alert.show();
            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                alert.setTitle("Error").setMessage("Volley error when get IP Address = " + error.getMessage()).show();
            }
        }));
    }
}

I get the error: "failed to authenticate with proxy"

Hi there,

This doesn't seem like a Volley question so much as it is one about HttpURLConnection, since Volley isn't at all involved in the proxy connection process. Presumably you'd have the same problem when using HttpURLConnection directly, since Volley isn't doing anything special here.

I'd recommend you remove Volley from the equation by using HttpURLConnection directly and figuring out why that's not working. If you're able to get things working directly, but for some reason Volley is causing problems, then feel free to reopen this with more details about the version that works and the one that doesn't. Otherwise, I'm closing this out as I do not believe there is a Volley issue here, and there are more suitable general help venues for how to use HttpURLConnections with proxy servers.
