Apache http client sample failing for Digest authentication
I am running the sample Apache hc (http client) for digest authentication. I didn't change anything, just using the provided sample:
public static void main(String[] args) throws Exception {
HttpHost target = new HttpHost("httpbin.org", 80, "http");
CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(
new AuthScope(target.getHostName(), target.getPort()),
new UsernamePasswordCredentials("user", "passwd"));
CloseableHttpClient httpclient = HttpClients.custom()
.setDefaultCredentialsProvider(credsProvider)
.build();
try {
// Create AuthCache instance
AuthCache authCache = new BasicAuthCache();
// Generate DIGEST scheme object, initialize it and add it to the local
// auth cache
DigestScheme digestAuth = new DigestScheme();
// Suppose we already know the realm name
digestAuth.overrideParamter("realm", "me@kennethreitz.com");
// Suppose we already know the expected nonce value
digestAuth.overrideParamter("nonce", "b2c603bb7c93cfa197945553a1044283");
authCache.put(target, digestAuth);
// Add AuthCache to the execution context
HttpClientContext localContext = HttpClientContext.create();
localContext.setAuthCache(authCache);
HttpGet httpget = new HttpGet("http://httpbin.org/digest-auth/auth/user/passwd");
System.out.println("Executing request " + httpget.getRequestLine() + " to target " + target);
for (int i = 0; i < 3; i++) {
CloseableHttpResponse response = httpclient.execute(target, httpget, localContext);
try {
System.out.println("----------------------------------------");
System.out.println(response.getStatusLine());
System.out.println(EntityUtils.toString(response.getEntity()));
} finally {
response.close();
}
}
} finally {
httpclient.close();
}
}
And I am getting: HTTP/1.1 401 UNAUTHORIZED
If I go direct to http://httpbin.org/digest-auth/auth/user/passwd in prompts me for user/passwd and then provides the page. So the website is working right.
Any idea what is wrong? I have the latest version of the library.
Fiddler Auth for browser (successful):
No Proxy-Authorization Header is present.
Authorization Header is present: Digest username="user", realm="me@kennethreitz.com", nonce="8ada87344eb5a10bf810bcc211205c24", uri="/digest-auth/auth/user/passwd", response="ad22423e5591d14c90c6fe3cd762e64c", opaque="361645844d957289c4c8f3479f76269f", qop=auth, nc=00000001, cnonce="260d8ddfe64bf32e"
Fiddler Auth for my code (failed):
No Proxy-Authorization Header is present.
Authorization Header is present: Digest username="user", realm="me@kennethreitz.com", nonce="76af6c9c0a1f57ee5f0fcade2a5f758c", uri="http://httpbin.org/digest-auth/auth/user/passwd", response="745686e3f38ab40ce5907d41f91823e6", qop=auth, nc=00000001, cnonce="634b618d5c8ac9af", algorithm=MD5, opaque="fe84ce11c48a7b258490600800e5e6df"
这段代码digestAuth.overrideParamter("realm", "some realm")应该有一些变化。用你的服务器"some realm"替换"some realm" 。请看这个问题
Ok I got it working. You have to set a cookie too. Thanks to this post for the help. The below code works - but only if you are not using Fiddler.
public static void main(String[] args) throws Exception {
CookieStore cookieStore = new BasicCookieStore();
BasicClientCookie cookie = new BasicClientCookie("fake", "fake_value");
cookie.setDomain("httpbin.org");
cookie.setPath("/");
cookieStore.addCookie(cookie);
// https://stackoverflow.com/questions/27291842/digest-auth-with-java-apache-client-always-401-unauthorized
HttpHost target = new HttpHost("httpbin.org", 80, "http");
CredentialsProvider credsProvider = new BasicCredentialsProvider();
credsProvider.setCredentials(
new AuthScope(target.getHostName(), target.getPort()),
new UsernamePasswordCredentials("user", "passwd"));
CloseableHttpClient httpclient = HttpClients.custom()
.setDefaultCookieStore(cookieStore)
.setDefaultCredentialsProvider(credsProvider)
// .setProxy(new HttpHost("127.0.0.1", 8888))
.build();
try {
// Create AuthCache instance
AuthCache authCache = new BasicAuthCache();
// Generate DIGEST scheme object, initialize it and add it to the local
// auth cache
DigestScheme digestAuth = new DigestScheme();
// Suppose we already know the realm name
digestAuth.overrideParamter("realm", "me@kennethreitz.com");
// Suppose we already know the expected nonce value
digestAuth.overrideParamter("nonce", calculateNonce());
authCache.put(target, digestAuth);
// Add AuthCache to the execution context
HttpClientContext localContext = HttpClientContext.create();
localContext.setAuthCache(authCache);
HttpGet httpget = new HttpGet("http://httpbin.org/digest-auth/auth/user/passwd");
System.out.println("Executing request " + httpget.getRequestLine() + " to target " + target);
CloseableHttpResponse response = httpclient.execute(target, httpget, localContext);
try {
System.out.println("----------------------------------------");
System.out.println(response.getStatusLine());
System.out.println(EntityUtils.toString(response.getEntity()));
} finally {
response.close();
}
} finally {
httpclient.close();
}
}
public 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());
}
