Question

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，仅使用提供的样本：

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

如果我直接转到http://httpbin.org/digest-auth/auth/user/passwd，提示我输入user / passwd然后提供页面。所以网站运作正常。

知道出了什么问题吗？我有最新版本的库。

Answer 1

此代码digestAuth.overrideParamter("realm", "some realm")应该有一些更改。要用您的服务器域替换"some realm"。请查看此question

Answer 2

好的我工作了。你也必须设置一个cookie。 Thanks to this post寻求帮助。以下代码有效 - 但前提是您使用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());
    }
