Apache HTTP客户端样本无法进行摘要式身份验证
我正在运行示例Apache hc（http客户端）进行摘要式身份验证。 我没有改变任何东西，只是使用提供的示例：
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();
}
}
我得到：HTTP / 1.1 401 UNAUTHORIZED
如果我直接进入http://httpbin.org/digest-auth/auth/user/passwd提示我输入user / passwd，然后提供页面。 所以这个网站是正确的。
任何想法有什么不对？ 我有最新版本的图书馆。
浏览器的提琴手验证（成功）：
没有代理授权标题存在。
授权标题存在：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”
我的代码提琴手认证（失败）：
没有代理授权标题存在。
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
好吧，我得到它的工作。 你也必须设置一个cookie。 感谢这篇文章的帮助。 下面的代码工作 - 但只有当你不使用提琴手。
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());
}
