Example 1 with HttpClient

use of org.mitre.taxii.client.HttpClient in project metron by apache.

the class TaxiiHandler method buildClient.

private static HttpClient buildClient(URL proxy, String username, String password) throws Exception {
    // Start with a default TAXII HTTP client.
    HttpClient client = new HttpClient();
    // Create an Apache HttpClientBuilder to be customized by the command line arguments.
    HttpClientBuilder builder = HttpClientBuilder.create().useSystemProperties();
    // Proxy
    if (proxy != null) {
        HttpHost proxyHost = new HttpHost(proxy.getHost(), proxy.getPort(), proxy.getProtocol());
        builder.setProxy(proxyHost);
    }
    // Basic authentication. User & Password
    if (username != null ^ password != null) {
        throw new Exception("'username' and 'password' arguments are required to appear together.");
    }
    // from:  http://stackoverflow.com/questions/19517538/ignoring-ssl-certificate-in-apache-httpclient-4-3
    SSLContextBuilder ssbldr = new SSLContextBuilder();
    ssbldr.loadTrustMaterial(null, new TrustSelfSignedStrategy());
    SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(ssbldr.build(), SSLConnectionSocketFactory.BROWSER_COMPATIBLE_HOSTNAME_VERIFIER);
    Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory>create().register("http", new PlainConnectionSocketFactory()).register("https", sslsf).build();
    PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager(registry);
    // max connection
    cm.setMaxTotal(20);
    // ""
    System.setProperty("jsse.enableSNIExtension", "false");
    CloseableHttpClient httpClient = builder.setSSLSocketFactory(sslsf).setConnectionManager(cm).build();
    client.setHttpclient(httpClient);
    return client;
}

Example 2 with HttpClient

use of org.mitre.taxii.client.HttpClient in project metron by apache.
