I am using the Aapache httpclient code to read for a url that has Digest authentication. I'm getting a security violation. This url/username/password works fine in a browser. What's wrong?
public static void main(String[] args) throws Exception {
String url = "https://httpbin.org/digest-auth/auth/user/passwd";
String username = "user";
String password = "passwd";
CookieStore cookieStore = new BasicCookieStore();
BasicClientCookie cookie = new BasicClientCookie("fake", "fake_value");
cookie.setDomain("httpbin.org");
cookie.setPath("/");
cookieStore.addCookie(cookie);
// get the host
HttpHost httpHost = URIUtils.extractHost(new URI(url));
CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(new AuthScope(httpHost.getHostName(), httpHost.getPort()), new UsernamePasswordCredentials(username, password));
CloseableHttpClient httpClient = HttpClients.custom()
.setDefaultCookieStore(cookieStore)
.setDefaultCredentialsProvider(credsProvider)
.setRedirectStrategy(new LaxRedirectStrategy())
.build();
// Create AuthCache instance
// Generate BASIC scheme object and add it to the local auth cache
AuthCache authCache = new BasicAuthCache();
DigestScheme digestAuth = new DigestScheme();
digestAuth.overrideParamter("realm", "support@windward.net");
digestAuth.overrideParamter("nonce", calculateNonce());
authCache.put(httpHost, digestAuth);
// Add AuthCache to the execution context
HttpClientContext localContext = HttpClientContext.create();
localContext.setAuthCache(authCache);
CloseableHttpResponse response = null;
HttpGet httpGet = new HttpGet(url);
response = httpClient.execute(httpHost, httpGet, localContext);
if (response.getStatusLine().getStatusCode() != 200)
throw new IOException("Error: " + response.getStatusLine() + ". Reading url " + url);
HttpEntity entity = response.getEntity();
InputStream stream = entity.getContent();
}
private static synchronized String calculateNonce() {
Date d = new Date();
SimpleDateFormat f = new SimpleDateFormat("yyyy:MM:dd:hh:mm:ss");
String fmtDate = f.format(d);
Random rand = new Random(100000);
Integer randomInt = rand.nextInt();
return org.apache.commons.codec.digest.DigestUtils.md5Hex(fmtDate + randomInt.toString());
}
