Appdynamics to monitor java httpclient and clientbuilder?

carlos_aguni — Tue, 19 Oct 2021 04:41:39 GMT

Hi all i wrote a dummy java/quarkus app that fetches html data from any web page.

my goal is to see the tier pointing to the endpoints in appdy's flowmap

my code

@GET
    @Path("/1")
    @Produces(MediaType.TEXT_PLAIN)
    public String test1(){
        try {
            CloseableHttpClient httpClient = HttpClients
                    .custom()
                    .setSSLContext(new SSLContextBuilder().loadTrustMaterial(null, TrustAllStrategy.INSTANCE).build())
                    .build();
            HttpGet request = new HttpGet("https://nylen.io/d3-spirograph/");
            CloseableHttpResponse response = httpClient.execute(request);
            System.out.println(response.getProtocolVersion());              // HTTP/1.1
            System.out.println(response.getStatusLine().getStatusCode());   // HTTP/1.1
            System.out.println(response.getStatusLine().getReasonPhrase()); // OK
            System.out.println(response.getStatusLine().toString());        // HTTP/1.1 200 OK

            HttpEntity entity = response.getEntity();
            if (entity != null){
                String result = EntityUtils.toString(entity);
                response.close();
                return result;
            }
        } catch (ClientProtocolException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        } catch (KeyStoreException e) {
            e.printStackTrace();
        } catch (KeyManagementException e) {
            e.printStackTrace();
        }

        return "ok";
    }

path /2

@GET
    @Path("/2")
    @Produces(MediaType.TEXT_PLAIN)
    public String test2() throws Exception{

        SSLContext sslcontext = SSLContext.getInstance("TLS");

        sslcontext.init(null, new TrustManager[]{new X509TrustManager() {
            public void checkClientTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {}
            public void checkServerTrusted(X509Certificate[] arg0, String arg1) throws CertificateException {}
            public X509Certificate[] getAcceptedIssuers() { return new X509Certificate[0]; }
        }}, new java.security.SecureRandom());

//        Client client = ClientBuilder.newClient()
        Client client = ClientBuilder.newBuilder()
                                .sslContext(sslcontext)
                                .hostnameVerifier((s1, s2) -> true)
                                .build();
        String ssb = "https://self-signed.badssl.com/";
        String response = client.target(ssb)
                //.queryParam("query", "q")
                .request()
                .accept("text/html")
                .get(String.class);
//                .post(Entity.entity("e", "text/plain"), String.class);
        client.close();
        return response;
    }
