使用 Apache httpclient for https

security ssl java tomcat apache-commons-httpclient
2022-09-01 02:39:44

我已经在tomcat中启用了https，并且有一个用于服务器身份验证的自签名证书。我使用Apache httpClient创建了一个http客户端。我设置了一个加载服务器证书的信任管理器。http客户端可以毫无问题地与服务器连接。为了查看发生了什么，我启用了调试：

System.setProperty("javax.net.debug", "ssl");

我看到了以下我根本无法理解的内容：

***

  Valid from Sat Mar 05 15:06:51 EET 2011 until Fri Jun 03 16:06:51 EEST 2011

我的证书被显示并添加到信任库（如我所见）。然后：

以下是我没有得到的调试跟踪的部分：

它似乎也使用默认的java信任存储区！我的问题是为什么会发生这种情况？

在我的代码中，我显式指定了要使用的特定信任存储区（通过信任存储管理器）。我本来以为只用这个。似乎我的信任库和java的默认值都被使用了。这是它应该如何工作吗？

更新：
我尝试了以下方法：

System.out.println("TMF No:"+tmf.getTrustManagers().length);
System.out.println("Class is "+tmf.getTrustManagers()[0].getClass().getName());

我认为我应该看到2个信任管理器，因为有2个密钥库（我的和java的默认值似乎被使用）。
但结果只有1个信任经理！

TMF No:1
Class is com.sun.net.ssl.internal.ssl.X509TrustManagerImpl

更新2：正如您在下面的代码中看到的，我指定了我的密钥库。我的期望是，只应该使用这个（而不是这个和cacert）

    HttpClient client = new DefaultHttpClient();
    SSLContext sslContext = SSLContext.getInstance("TLS");      

    TrustManagerFactory tmf = TrustManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
    KeyStore ks = KeyStore.getInstance("JKS");
    File trustFile = new File("clientTrustStore.jks");
    ks.load(new FileInputStream(trustFile), null);
    tmf.init(ks);
    sslContext.init(null, tmf.getTrustManagers(),null);  
    SSLSocketFactory sf = new SSLSocketFactory(sslContext); 
    sf.setHostnameVerifier(SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
    Scheme scheme = new Scheme("https", sf, 443);
    client.getConnectionManager().getSchemeRegistry().register(scheme);
    httpGet = new HttpGet("https://localhost:8443/myApp");
    HttpResponse httpResponse = client.execute(httpGet);

对我来说没有意义。


答案 1

我把这个测试应用程序放在一起，使用Apache HttpClient包中的HTTP测试框架重现问题：

ClassLoader cl = HCTest.class.getClassLoader();
URL url = cl.getResource("test.keystore");
KeyStore keystore  = KeyStore.getInstance("jks");
char[] pwd = "nopassword".toCharArray();
keystore.load(url.openStream(), pwd);

TrustManagerFactory tmf = TrustManagerFactory.getInstance(
        TrustManagerFactory.getDefaultAlgorithm());
tmf.init(keystore);
TrustManager[] tm = tmf.getTrustManagers();

KeyManagerFactory kmfactory = KeyManagerFactory.getInstance(
        KeyManagerFactory.getDefaultAlgorithm());
kmfactory.init(keystore, pwd);
KeyManager[] km = kmfactory.getKeyManagers();

SSLContext sslcontext = SSLContext.getInstance("TLS");
sslcontext.init(km, tm, null);

LocalTestServer localServer = new LocalTestServer(sslcontext);
localServer.registerDefaultHandlers();

localServer.start();
try {

    DefaultHttpClient httpclient = new DefaultHttpClient();
    TrustStrategy trustStrategy = new TrustStrategy() {

        public boolean isTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            for (X509Certificate cert: chain) {
                System.err.println(cert);
            }
            return false;
        }

    };

    SSLSocketFactory sslsf = new SSLSocketFactory("TLS", null, null, keystore, null,
            trustStrategy, new AllowAllHostnameVerifier());
    Scheme https = new Scheme("https", 443, sslsf);
    httpclient.getConnectionManager().getSchemeRegistry().register(https);

    InetSocketAddress address = localServer.getServiceAddress();
    HttpHost target1 = new HttpHost(address.getHostName(), address.getPort(), "https");
    HttpGet httpget1 = new HttpGet("/random/100");
    HttpResponse response1 = httpclient.execute(target1, httpget1);
    System.err.println(response1.getStatusLine());
    HttpEntity entity1 = response1.getEntity();
    EntityUtils.consume(entity1);
    HttpHost target2 = new HttpHost("www.verisign.com", 443, "https");
    HttpGet httpget2 = new HttpGet("/");
    HttpResponse response2 = httpclient.execute(target2, httpget2);
    System.err.println(response2.getStatusLine());
    HttpEntity entity2 = response2.getEntity();
    EntityUtils.consume(entity2);
} finally {
    localServer.stop();
}

尽管由于某种原因，Sun 的 JSSE 实现似乎总是从默认信任存储区读取信任材料，但它似乎并没有被添加到 SSL 上下文中，也不会影响 SSL 握手期间的信任验证过程。

下面是测试应用的输出。如您所见，第一个请求成功，而第二个请求失败，因为与 www.verisign.com 的连接被拒绝为不受信任。

答案 2

当我使用Apache HTTP Client 4.3时，我正在使用HTTP客户端的池连接管理器或基本连接管理器。通过使用java SSL调试，我注意到这些类加载了cacerts信任存储，而不是我以编程方式指定的存储。

PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager();
BasicHttpClientConnectionManager cm = new BasicHttpClientConnectionManager();
builder.setConnectionManager( cm );

我想使用它们，但最终删除了它们并创建了一个没有它们的HTTP客户端。请注意，构建器是一个HttpClientBuilder。

我在使用Java SSL调试标志运行程序时进行了确认，并在调试器中停止。我使用 -Djavax.net.debug=ssl 作为 VM 参数。我在调试器中停止了我的代码，当构造上述任何一个*ClientConnectionManager时，将加载cacerts文件。
