How to get the final redirected URL when using reactive WebClient with followRedirect(true)

Question

How do I get the final URL?
(The URL http://mz.cm/1gpgLAJ is redirected to https://moz.com/blog/announcing-mozcon-local-2016?utm_source=twitter&utm_medium=social&utm_content=announcing_mozcon_local_2016&utm_campaign=blog_post)

WebClient.builder()
                .clientConnector(new ReactorClientHttpConnector(
                        HttpClient.create().followRedirect(true)
                )).build()
                .get()
                .uri("http://mz.cm/1gpgLAJ")
                .exchangeToMono(clientResponse -> {
                    ....
                });

You can listen for redirect event with doOnRedirect. See below your example extended with doOnRedirect callback. More information about lifecycle callbacks you can find here.

WebClient.builder()
            .clientConnector(new ReactorClientHttpConnector(
                    HttpClient.create().followRedirect(true)
                        .doOnRedirect((res, conn) ->
                            System.out.println("Location header: " + res.responseHeaders().get("Location")))
            )).build()
            .get()
            .uri("http://mz.cm/1gpgLAJ")
            .exchangeToMono(clientResponse -> {
                ....
            });
