使用 Apache HttpClient 4 进行抢占式基本身份验证

发布于 2024-08-16 20:29:03 字数 402 浏览 7 评论 0原文

有没有比描述的更简单的方法来设置http客户端以进行抢占式基本身份验证 这里？
在以前的版本 (3.x) 中，它曾经是一个简单的方法调用（例如，httpClient.getParams().setAuthenticationPreemptive(true)）。
我想避免的主要事情是将 BasicHttpContext 添加到我执行的每个方法中。

Is there an easier way to setup the http client for preemptive basic authentication than what described here?
In previous version (3.x) it used to be a simple method call (eg, httpClient.getParams().setAuthenticationPreemptive(true)).
The main thing I want to avoid is adding the BasicHttpContext to each method I execute.

如果您希望强制 HttpClient 4 通过单个请求进行身份验证，则可以使用以下方法：

String username = ...
String password = ...
UsernamePasswordCredentials creds = new UsernamePasswordCredentials(username, password);

HttpRequest request = ...
request.addHeader(new BasicScheme().authenticate(creds, request));

If you are looking to force HttpClient 4 to authenticate with a single request, the following will work:

String username = ...
String password = ...
UsernamePasswordCredentials creds = new UsernamePasswordCredentials(username, password);

HttpRequest request = ...
request.addHeader(new BasicScheme().authenticate(creds, request));

如果不每次都传递上下文，很难做到这一点，但您可以通过使用请求拦截器来做到这一点。这是我们使用的一些代码（从他们的 JIRA、iirc 中找到）：

// Pre-emptive authentication to speed things up
BasicHttpContext localContext = new BasicHttpContext();

BasicScheme basicAuth = new BasicScheme();
localContext.setAttribute("preemptive-auth", basicAuth);

httpClient.addRequestInterceptor(new PreemptiveAuthInterceptor(), 0);

(...)

static class PreemptiveAuthInterceptor implements HttpRequestInterceptor {

    public void process(final HttpRequest request, final HttpContext context) throws HttpException, IOException {
        AuthState authState = (AuthState) context.getAttribute(ClientContext.TARGET_AUTH_STATE);

        // If no auth scheme avaialble yet, try to initialize it
        // preemptively
        if (authState.getAuthScheme() == null) {
            AuthScheme authScheme = (AuthScheme) context.getAttribute("preemptive-auth");
            CredentialsProvider credsProvider = (CredentialsProvider) context.getAttribute(ClientContext.CREDS_PROVIDER);
            HttpHost targetHost = (HttpHost) context.getAttribute(ExecutionContext.HTTP_TARGET_HOST);
            if (authScheme != null) {
                Credentials creds = credsProvider.getCredentials(new AuthScope(targetHost.getHostName(), targetHost.getPort()));
                if (creds == null) {
                    throw new HttpException("No credentials for preemptive authentication");
                }
                authState.setAuthScheme(authScheme);
                authState.setCredentials(creds);
            }
        }

    }

}

It's difficult to do this without passing a context through every time, but you can probably do it by using a request interceptor. Here is some code that we use (found from their JIRA, iirc):

// Pre-emptive authentication to speed things up
BasicHttpContext localContext = new BasicHttpContext();

BasicScheme basicAuth = new BasicScheme();
localContext.setAttribute("preemptive-auth", basicAuth);

httpClient.addRequestInterceptor(new PreemptiveAuthInterceptor(), 0);

(...)

static class PreemptiveAuthInterceptor implements HttpRequestInterceptor {

    public void process(final HttpRequest request, final HttpContext context) throws HttpException, IOException {
        AuthState authState = (AuthState) context.getAttribute(ClientContext.TARGET_AUTH_STATE);

        // If no auth scheme avaialble yet, try to initialize it
        // preemptively
        if (authState.getAuthScheme() == null) {
            AuthScheme authScheme = (AuthScheme) context.getAttribute("preemptive-auth");
            CredentialsProvider credsProvider = (CredentialsProvider) context.getAttribute(ClientContext.CREDS_PROVIDER);
            HttpHost targetHost = (HttpHost) context.getAttribute(ExecutionContext.HTTP_TARGET_HOST);
            if (authScheme != null) {
                Credentials creds = credsProvider.getCredentials(new AuthScope(targetHost.getHostName(), targetHost.getPort()));
                if (creds == null) {
                    throw new HttpException("No credentials for preemptive authentication");
                }
                authState.setAuthScheme(authScheme);
                authState.setCredentials(creds);
            }
        }

    }

这与 Mat 的 Mannion 的解决方案相同，但您不必将 localContext 放入每个请求中。它更简单，但它为所有请求添加了身份验证。如果您无法控制单个请求，那么很有用，就像我使用 Apache Solr 时的情况一样，它在内部使用 HttpClient。

import org.apache.http.HttpException;
import org.apache.http.HttpHost;
import org.apache.http.HttpRequest;
import org.apache.http.HttpRequestInterceptor;
import org.apache.http.auth.AuthScope;
import org.apache.http.auth.AuthState;
import org.apache.http.auth.Credentials;
import org.apache.http.client.CredentialsProvider;
import org.apache.http.client.protocol.HttpClientContext;
import org.apache.http.impl.auth.BasicScheme;
import org.apache.http.protocol.HttpContext;
import org.apache.http.protocol.HttpCoreContext;

httpClient.addRequestInterceptor(new PreemptiveAuthInterceptor(), 0);

(...)

static class PreemptiveAuthInterceptor implements HttpRequestInterceptor {

    public void process(final HttpRequest request, final HttpContext context) throws HttpException, IOException {
         AuthState authState = (AuthState) context.getAttribute(HttpClientContext.TARGET_AUTH_STATE);

         // If no auth scheme available yet, try to initialize it
         // preemptively
         if (authState.getAuthScheme() == null) {
             CredentialsProvider credsProvider = (CredentialsProvider) context.getAttribute(HttpClientContext.CREDS_PROVIDER);
             HttpHost targetHost = (HttpHost) context.getAttribute(HttpCoreContext.HTTP_TARGET_HOST);
             Credentials creds = credsProvider.getCredentials(new AuthScope(targetHost.getHostName(), targetHost.getPort()));
             if (creds == null) {
                 throw new HttpException("No credentials for preemptive authentication");
             }
             authState.update(new BasicScheme(), creds);
         }
     }
}

当然，您必须设置凭据提供程序：

httpClient.getCredentialsProvider().setCredentials(
                new AuthScope(url.getHost(), url.getPort()),
                new UsernamePasswordCredentials(username, password))

AuthScope 不得包含领域，因为它事先是未知的。

This is the same solution as Mat's Mannion's, but you don't have to put localContext to each request. It's simpler, but it adds authentication to ALL requests. Useful, if you don't have control over individual requests, as in my case when using Apache Solr, which uses HttpClient internally.

import org.apache.http.HttpException;
import org.apache.http.HttpHost;
import org.apache.http.HttpRequest;
import org.apache.http.HttpRequestInterceptor;
import org.apache.http.auth.AuthScope;
import org.apache.http.auth.AuthState;
import org.apache.http.auth.Credentials;
import org.apache.http.client.CredentialsProvider;
import org.apache.http.client.protocol.HttpClientContext;
import org.apache.http.impl.auth.BasicScheme;
import org.apache.http.protocol.HttpContext;
import org.apache.http.protocol.HttpCoreContext;

httpClient.addRequestInterceptor(new PreemptiveAuthInterceptor(), 0);

(...)

static class PreemptiveAuthInterceptor implements HttpRequestInterceptor {

    public void process(final HttpRequest request, final HttpContext context) throws HttpException, IOException {
         AuthState authState = (AuthState) context.getAttribute(HttpClientContext.TARGET_AUTH_STATE);

         // If no auth scheme available yet, try to initialize it
         // preemptively
         if (authState.getAuthScheme() == null) {
             CredentialsProvider credsProvider = (CredentialsProvider) context.getAttribute(HttpClientContext.CREDS_PROVIDER);
             HttpHost targetHost = (HttpHost) context.getAttribute(HttpCoreContext.HTTP_TARGET_HOST);
             Credentials creds = credsProvider.getCredentials(new AuthScope(targetHost.getHostName(), targetHost.getPort()));
             if (creds == null) {
                 throw new HttpException("No credentials for preemptive authentication");
             }
             authState.update(new BasicScheme(), creds);
         }
     }
}

Of course, you have to set the credentials provider:

httpClient.getCredentialsProvider().setCredentials(
                new AuthScope(url.getHost(), url.getPort()),
                new UsernamePasswordCredentials(username, password))

The AuthScope must not contain realm, as it is not known in advance.

上面的很多答案都使用了已弃用的代码。我正在使用 Apache SOLRJ 版本 5.0.0。
我的代码由

private HttpSolrClient solrClient; 

private void initialiseSOLRClient() {
            URL solrURL = null;
            try {
                solrURL = new URL(urlString);
            } catch (MalformedURLException e) {
                LOG.error("Cannot parse the SOLR URL!!" + urlString);
                throw new SystemException("Cannot parse the SOLR URL!! " + urlString, e);
            }
            String host = solrURL.getHost();
            int port = solrURL.getPort();
            AuthScope authScope = new AuthScope(host, port);

    BasicTextEncryptor textEncryptor = new BasicTextEncryptor();
    textEncryptor.setPassword("red bananas in the spring");
    String decryptPass = textEncryptor.decrypt(pass);
    UsernamePasswordCredentials creds = new UsernamePasswordCredentials(userName, decryptPass);

    CredentialsProvider credsProvider = new BasicCredentialsProvider();
    credsProvider.setCredentials(
            authScope,
            creds);

    HttpClientBuilder builder = HttpClientBuilder.create();
    builder.addInterceptorFirst(new PreemptiveAuthInterceptor());
    builder.setDefaultCredentialsProvider(credsProvider);
    CloseableHttpClient httpClient = builder.build();

    solrClient = new HttpSolrClient(urlString, httpClient);
}

PreemptiveAuthInterceptor 组成，现在如下：-

static class PreemptiveAuthInterceptor implements HttpRequestInterceptor {

    public void process(final HttpRequest request, final HttpContext context) throws HttpException, IOException {
        AuthState authState = (AuthState) context.getAttribute(HttpClientContext.TARGET_AUTH_STATE);
        // If no auth scheme available yet, try to initialize it
        // preemptively
        if (authState.getAuthScheme() == null) {
            CredentialsProvider credsProvider = (CredentialsProvider) 
                        context.getAttribute(HttpClientContext.CREDS_PROVIDER);
            HttpHost targetHost = (HttpHost) context.getAttribute(HttpCoreContext.HTTP_TARGET_HOST);
            AuthScope authScope = new AuthScope(targetHost.getHostName(), targetHost.getPort());
            Credentials creds = credsProvider.getCredentials(authScope);
            if(creds == null){

            }
            authState.update(new BasicScheme(), creds);
        }

    }
}

A lot of the answers above use deprecated code. I am using Apache SOLRJ version 5.0.0.
My code consists of

private HttpSolrClient solrClient; 

private void initialiseSOLRClient() {
            URL solrURL = null;
            try {
                solrURL = new URL(urlString);
            } catch (MalformedURLException e) {
                LOG.error("Cannot parse the SOLR URL!!" + urlString);
                throw new SystemException("Cannot parse the SOLR URL!! " + urlString, e);
            }
            String host = solrURL.getHost();
            int port = solrURL.getPort();
            AuthScope authScope = new AuthScope(host, port);

    BasicTextEncryptor textEncryptor = new BasicTextEncryptor();
    textEncryptor.setPassword("red bananas in the spring");
    String decryptPass = textEncryptor.decrypt(pass);
    UsernamePasswordCredentials creds = new UsernamePasswordCredentials(userName, decryptPass);

    CredentialsProvider credsProvider = new BasicCredentialsProvider();
    credsProvider.setCredentials(
            authScope,
            creds);

    HttpClientBuilder builder = HttpClientBuilder.create();
    builder.addInterceptorFirst(new PreemptiveAuthInterceptor());
    builder.setDefaultCredentialsProvider(credsProvider);
    CloseableHttpClient httpClient = builder.build();

    solrClient = new HttpSolrClient(urlString, httpClient);
}

The PreemptiveAuthInterceptor is now as follows:-

static class PreemptiveAuthInterceptor implements HttpRequestInterceptor {

    public void process(final HttpRequest request, final HttpContext context) throws HttpException, IOException {
        AuthState authState = (AuthState) context.getAttribute(HttpClientContext.TARGET_AUTH_STATE);
        // If no auth scheme available yet, try to initialize it
        // preemptively
        if (authState.getAuthScheme() == null) {
            CredentialsProvider credsProvider = (CredentialsProvider) 
                        context.getAttribute(HttpClientContext.CREDS_PROVIDER);
            HttpHost targetHost = (HttpHost) context.getAttribute(HttpCoreContext.HTTP_TARGET_HOST);
            AuthScope authScope = new AuthScope(targetHost.getHostName(), targetHost.getPort());
            Credentials creds = credsProvider.getCredentials(authScope);
            if(creds == null){

            }
            authState.update(new BasicScheme(), creds);
        }

    }

聚会有点晚了，但我遇到了试图解决此问题的帖子请求的代理预授权的线程。为了补充亚当的回应，我发现以下内容对我有用：

HttpPost httppost = new HttpPost(url);
UsernamePasswordCredentials creds = new UsernamePasswordCredentials(username, password);
Header bs = new BasicScheme().authenticate(creds, httppost);
httppost.addHeader("Proxy-Authorization", bs.getValue());

认为这可能对遇到此问题的其他人有帮助。

A little late to the party but I came accross the thread trying to solve this for proxy pre-authorization of a post request. To add to Adam's response, I found the following worked for me:

HttpPost httppost = new HttpPost(url);
UsernamePasswordCredentials creds = new UsernamePasswordCredentials(username, password);
Header bs = new BasicScheme().authenticate(creds, httppost);
httppost.addHeader("Proxy-Authorization", bs.getValue());

Thought that might be helpful for anyone else who runs into this.

我认为最好的方法可能是手动完成。我添加了以下函数

Classic Java：

import javax.xml.bind.DatatypeConverter;

...

private static void addAuthHeader(HttpRequestBase http, String username, String password) throws UnsupportedEncodingException {
        String encoded = DatatypeConverter.printBase64Binary((username + ":" + password).getBytes("UTF-8"));
        http.addHeader("AUTHORIZATION", "Basic " + encoded);
    }

的实例

HTTPRequestBase 可以是 HttpGet 或 HttpPost Android

import android.util.Base64;

： ...

private static void addAuthHeader(HttpRequestBase http, String username, String password) throws UnsupportedEncodingException {
    String encoded = Base64.encodeToString((username + ":" + password).getBytes("UTF-8"), Base64.NO_WRAP);
    http.addHeader("AUTHORIZATION", "Basic " + encoded);
}

I think the best way may be to just do it manually. I added the following function

Classic Java:

import javax.xml.bind.DatatypeConverter;

...

private static void addAuthHeader(HttpRequestBase http, String username, String password) throws UnsupportedEncodingException {
        String encoded = DatatypeConverter.printBase64Binary((username + ":" + password).getBytes("UTF-8"));
        http.addHeader("AUTHORIZATION", "Basic " + encoded);
    }

HTTPRequestBase can be an instance of HttpGet or HttpPost

Android:

import android.util.Base64;

...

private static void addAuthHeader(HttpRequestBase http, String username, String password) throws UnsupportedEncodingException {
    String encoded = Base64.encodeToString((username + ":" + password).getBytes("UTF-8"), Base64.NO_WRAP);
    http.addHeader("AUTHORIZATION", "Basic " + encoded);

我正在使用此代码，基于我对 HTTPClient 4.5 文档：

HttpClientContext ctx = HttpClientContext.create()
ctx.setCredentialsProvider(new BasicCredentialsProvider())
ctx.setAuthCache(new BasicAuthCache())
UsernamePasswordCredentials creds = new UsernamePasswordCredentials(user, pass)
AuthScope authScope = new AuthScope(host, port)
ctx.getCredentialsProvider.setCredentials(authScope, credentials)

// This part makes authentication preemptive:
HttpHost targetHost = new HttpHost(host, port, scheme)
ctx.getAuthCache.put(targetHost, new BasicScheme())

...并确保始终将该上下文传递给 HTTPClient.execute()。

I'm using this code, based on my reading of the HTTPClient 4.5 docs:

HttpClientContext ctx = HttpClientContext.create()
ctx.setCredentialsProvider(new BasicCredentialsProvider())
ctx.setAuthCache(new BasicAuthCache())
UsernamePasswordCredentials creds = new UsernamePasswordCredentials(user, pass)
AuthScope authScope = new AuthScope(host, port)
ctx.getCredentialsProvider.setCredentials(authScope, credentials)

// This part makes authentication preemptive:
HttpHost targetHost = new HttpHost(host, port, scheme)
ctx.getAuthCache.put(targetHost, new BasicScheme())

...and make sure you always pass that context to HTTPClient.execute().

我不太明白你的结束语。 HttpClient 拥有用于执行抢占式身份验证的所有机制，并且您只需执行一次（当您构造和配置 HttpClient 时）。完成此操作后，您可以像往常一样构建方法实例。您不“将 BasicHttpContext 添加到该方法中”。

我认为，您最好的选择是拥有自己的对象来设置抢占式身份验证所需的所有垃圾，并具有一个或多个简单方法来在给定的 HTTPMethod 对象上执行请求。

I don't quite get your closing comment. It's the HttpClient that has all of that machinery for doing preemptive auth, and you only have to do that once (when you construct and configure your HttpClient). Once you've done that, you construct your method instances the same way as always. You don't "add the BasicHttpContext" to the method.

Your best bet, I'd think, is to have your own object that sets up all of the junk required for preemptive auth, and has a simple method or methods for executing requests on given HTTPMethod objects.

在android中，Mat Mannion的答案无法解析https，仍然发送两个请求，你可以像下面这样做，技巧是附加authHeader与user-agent：

    public static DefaultHttpClient createProxyHttpClient() {
        try {

in android,Mat Mannion's answer can't resolve https,still send two requests,you can do like below,the trick is append authHeader with user-agent：

    public static DefaultHttpClient createProxyHttpClient() {
        try {
            final DefaultHttpClient client = createPlaintHttpClient();
            client.setRoutePlanner(new HttpRoutePlanner() {
                @Override
                public HttpRoute determineRoute(HttpHost target, HttpRequest request, HttpContext context) throws HttpException {
                    boolean isSecure = "https".equalsIgnoreCase(target.getSchemeName());
                    if (needProxy) {
                        Header header = isSecure ? ProxyUtils.createHttpsAuthHeader() : ProxyUtils.createAuthHeader();
                        if (isSecure) {
                            client.getParams().setParameter(CoreProtocolPNames.USER_AGENT, com.netease.cloudmusic.utils.HttpRequest.USER_AGENT + "\r\n" + header.getName() + ":" + header.getValue());
                        } else {
                            client.getParams().setParameter(CoreProtocolPNames.USER_AGENT, com.netease.cloudmusic.utils.HttpRequest.USER_AGENT);
                            if (request instanceof RequestWrapper) {
                                request = ((RequestWrapper) request).getOriginal();
                            }
                            request.setHeader(header);
                        }
                        String host = isSecure ? ProxyUtils.SECURE_HOST : ProxyUtils.HOST;
                        int port = isSecure ? ProxyUtils.SECURE_PORT : ProxyUtils.PORT;
                        return new HttpRoute(target, null,  new HttpHost(host, port), isSecure);
                    } else {
                        client.getParams().setParameter(CoreProtocolPNames.USER_AGENT, com.netease.cloudmusic.utils.HttpRequest.USER_AGENT);
                        return new HttpRoute(target, null, isSecure);
                    }
                }
            });
            return client;
        } catch (Exception e) {
            e.printStackTrace();
            return new DefaultHttpClient();
        }
    }

public static DefaultHttpClient createPlaintHttpClient() {
       try {
            KeyStore trustStore = KeyStore.getInstance(KeyStore.getDefaultType());
            trustStore.load(null, null);
            PlainSSLSocketFactory socketFactory = new PlainSSLSocketFactory(trustStore);

            BasicHttpParams params = new BasicHttpParams();
            HttpConnectionParams.setConnectionTimeout(params, 30000);
            HttpConnectionParams.setSoTimeout(params, 30000);
            HttpProtocolParams.setVersion(params, HttpVersion.HTTP_1_1);
            HttpProtocolParams.setContentCharset(params, HTTP.UTF_8);
            SchemeRegistry registry = new SchemeRegistry();
            registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
            registry.register(new Scheme("https", socketFactory, 443));
            ThreadSafeClientConnManager ccm = new ThreadSafeClientConnManager(params, registry);
            HttpClientParams.setCookiePolicy(params, CookiePolicy.BROWSER_COMPATIBILITY);
            final DefaultHttpClient client = new DefaultHttpClient(ccm, params);
            client.setRoutePlanner(new HttpRoutePlanner() {
        @Override
        public HttpRoute determineRoute(HttpHost target, HttpRequest arg1, HttpContext arg2) throws HttpException {

            return new HttpRoute(target, null, "https".equalsIgnoreCase(target.getSchemeName()));
        }
        });
            return client;
        } catch (Exception e) {
            e.printStackTrace();
            return new DefaultHttpClient();
        }
