Method for Proxy Authentication

[SwitchGM]

Hey there, I'm currently using devtools with a proxy and have been very unlucky in finding a way to authenticate with it. I'm very sure that there is a method, as the docs have Network.AuthChallange , and Network.AuthChallangeResponse types. Unfortunatly I have been unable to find any example code using these or any code using devtools to authenticate proxies.

Here is an example how I did it in PHP (I use https://github.com/chrome-php/chrome/). I hope it will give you some ideas:

// enable request interception (important!!!)
// it allows the browser to inform us that we need to complete a username/password authorization.
$page->getSession()->sendMessageSync(new Message('Network.setRequestInterception', ['patterns' => [['urlPattern' => '*']]]));

// this method allows you to approve or block request (we are only approving here)
$page->getSession()->on('method:Network.requestIntercepted', function (array $params): void {

    // the browser is letting us know that we need to provide proxy (or 401) credentials (normally, happens only once)
    if (isset($params["authChallenge"])) {
        // approving request and sending username/password
        $page->getSession()->sendMessageSync(
            new Message('Network.continueInterceptedRequest', ['interceptionId' => $params["interceptionId"], 'authChallengeResponse' => ['response' => 'ProvideCredentials', 'username' => "proxy_username", 'password' => "proxy_password"]])
        );
    } else {
        // simply approving request
        $page->getSession()->sendMessageSync(
            new Message('Network.continueInterceptedRequest', ['interceptionId' => $params["interceptionId"]])
        );

    }

});
