忽略Apache HttpClient 4.3中的SSL证书-Java 学习之路

如何忽略Apache HttpClient 4.3的SSL证书（全部信任）？

我在SO上找到的所有答案都会处理以前的版本，并且API已更改 .

以下代码适用于信任自签名证书 . 创建客户端时必须使用TrustSelfSignedStrategy：

SSLContextBuilder builder = new SSLContextBuilder();
    builder.loadTrustMaterial(null, new TrustSelfSignedStrategy());
    SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
            builder.build());
    CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(
            sslsf).build();

    HttpGet httpGet = new HttpGet("https://some-server");
    CloseableHttpResponse response = httpclient.execute(httpGet);
    try {
        System.out.println(response.getStatusLine());
        HttpEntity entity = response.getEntity();
        EntityUtils.consume(entity);
    }
    finally {
        response.close();
    }

我没有故意包含 SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER ：重点是允许使用自签名证书进行测试，这样您就不必从证书颁发机构获取适当的证书 . 您可以使用正确的主机名轻松创建自签名证书，这样做而不是添加 SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER 标志 .

如果您使用上面的PoolingHttpClientConnectionManager过程不起作用，则忽略自定义SSLContext . 创建PoolingHttpClientConnectionManager时，必须在构造函数中传递socketFactoryRegistry .

SSLContextBuilder builder = SSLContexts.custom();
builder.loadTrustMaterial(null, new TrustStrategy() {
    @Override
    public boolean isTrusted(X509Certificate[] chain, String authType)
            throws CertificateException {
        return true;
    }
});
SSLContext sslContext = builder.build();
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
        sslContext, new X509HostnameVerifier() {
            @Override
            public void verify(String host, SSLSocket ssl)
                    throws IOException {
            }

            @Override
            public void verify(String host, X509Certificate cert)
                    throws SSLException {
            }

            @Override
            public void verify(String host, String[] cns,
                    String[] subjectAlts) throws SSLException {
            }

            @Override
            public boolean verify(String s, SSLSession sslSession) {
                return true;
            }
        });

Registry<ConnectionSocketFactory> socketFactoryRegistry = RegistryBuilder
        .<ConnectionSocketFactory> create().register("https", sslsf)
        .build();

PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager(
        socketFactoryRegistry);
CloseableHttpClient httpclient = HttpClients.custom()
        .setConnectionManager(cm).build();

作为@mavroprovato答案的补充，如果你想信任所有证书而不仅仅是自签名，那么（你的代码风格）

builder.loadTrustMaterial(null, new TrustStrategy(){
    public boolean isTrusted(X509Certificate[] chain, String authType)
        throws CertificateException {
        return true;
    }
});

或（从我自己的代码直接复制粘贴）：

import javax.net.ssl.SSLContext;
import org.apache.http.ssl.TrustStrategy;
import org.apache.http.ssl.SSLContexts;

// ...

        SSLContext sslContext = SSLContexts
                .custom()
                //FIXME to contain real trust store
                .loadTrustMaterial(new TrustStrategy() {
                    @Override
                    public boolean isTrusted(X509Certificate[] chain,
                        String authType) throws CertificateException {
                        return true;
                    }
                })
                .build();

如果你想跳过主机名验证，你需要设置

CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(
            sslsf).setSSLHostnameVerifier( NoopHostnameVerifier.INSTANCE).build();

同样 . （不推荐使用ALLOW_ALL_HOSTNAME_VERIFIER） .

强制警告：你不应该这样做，接受所有证书是一件坏事 . 但是，有一些罕见的用例需要执行此操作 .

作为前面给出的代码的注释，即使httpclient.execute（）抛出异常，您也希望关闭响应

CloseableHttpResponse response = null;
try {
    response = httpclient.execute(httpGet);
    System.out.println(response.getStatusLine());
    HttpEntity entity = response.getEntity();
    EntityUtils.consume(entity);
}
finally {
    if (response != null) {
        response.close();
    }
}

上面的代码使用了测试

    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5.3</version>
</dependency>

vasekt给出的一个小补充：

使用PoolingHttpClientConnectionManager时，提供的SocketFactoryRegistry解决方案可以正常工作 .

但是，通过普通http的连接不再起作用 . 您还必须为http协议添加一个PlainConnectionSocketFactory，以使它们再次工作：
```
Registry<ConnectionSocketFactory> socketFactoryRegistry = 
  RegistryBuilder.<ConnectionSocketFactory> create()
  .register("https", sslsf)
  .register("http", new PlainConnectionSocketFactory()).build();
```

尝试各种选项后，以下配置适用于http和https

SSLContextBuilder builder = new SSLContextBuilder();
        builder.loadTrustMaterial(null, new TrustSelfSignedStrategy());
        SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(builder.build(),SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);


        Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory>create()
                .register("http", new PlainConnectionSocketFactory())
                .register("https", sslsf)
                .build();


        PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager(registry);
        cm.setMaxTotal(2000);//max connection


        //System.setProperty("jsse.enableSNIExtension", "false"); //""
        CloseableHttpClient httpClient = HttpClients.custom()
                .setSSLSocketFactory(sslsf)
                .setConnectionManager(cm)

更简单，更短的工作代码：

我们正在使用HTTPClient 4.3.5并且我们尝试了几乎所有解决方案都存在于stackoverflow上但没有任何问题，在思考并找出问题之后，我们来到下面的代码，它完美地工作，只需在创建HttpClient实例之前添加它 . 你用来发帖请求的一些方法......

SSLContextBuilder builder = new SSLContextBuilder();
    builder.loadTrustMaterial(null, new TrustStrategy() {
        @Override
        public boolean isTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            return true;
        }
    });

    SSLConnectionSocketFactory sslSF = new SSLConnectionSocketFactory(builder.build(),
            SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);

    HttpClient httpClient = HttpClients.custom().setSSLSocketFactory(sslSF).build();

使用http客户端4.5时，我必须使用javasx.net.ssl.HostnameVerifier来允许任何主机名（用于测试目的） . 这是我最终做的事情：

CloseableHttpClient httpClient = null;
    try {
        SSLContextBuilder sslContextBuilder = new SSLContextBuilder();
        sslContextBuilder.loadTrustMaterial(null, new TrustSelfSignedStrategy());

        HostnameVerifier hostnameVerifierAllowAll = new HostnameVerifier() 
            {
                public boolean verify(String hostname, SSLSession session) {
                    return true;
                }
            };

        SSLConnectionSocketFactory sslSocketFactory = new SSLConnectionSocketFactory(sslContextBuilder.build(), hostnameVerifierAllowAll);

        CredentialsProvider credsProvider = new BasicCredentialsProvider();
        credsProvider.setCredentials(
            new AuthScope("192.168.30.34", 8443),
            new UsernamePasswordCredentials("root", "password"));

        httpClient = HttpClients.custom()
            .setSSLSocketFactory(sslSocketFactory)
            .setDefaultCredentialsProvider(credsProvider)
            .build();

        HttpGet httpGet = new HttpGet("https://192.168.30.34:8443/axis/services/getStuff?firstResult=0&maxResults=1000");

        CloseableHttpResponse response = httpClient.execute(httpGet);

        int httpStatus = response.getStatusLine().getStatusCode();
        if (httpStatus >= 200 && httpStatus < 300) { [...]
        } else {
            throw new ClientProtocolException("Unexpected response status: " + httpStatus);
        }

    } catch (Exception ex) {
        ex.printStackTrace();
    }
    finally {
        try {
            httpClient.close();
        } catch (IOException ex) {
            logger.error("Error while closing the HTTP client: ", ex);

        public boolean verify(String hostname, SSLSession session) {
            return true;

（我会直接在vasekt的答案中添加评论，但我没有足够的声望点（不确定那里的逻辑）

无论如何...我想说的是，即使你没有明确地创建/要求PoolingConnection，也不意味着你没有得到它 .

我疯狂地想弄清楚为什么原来的解决方案不适合我，但我忽略了vasekt的答案，因为它“不适用于我的情况” - 错了！

我低时盯着我的堆栈跟踪，看到我在它的中间看到了一个PoolingConnection . 砰 - 我累了他的补充和成功！（我们的演示是明天，我变得绝望）:-)

private HttpClient getSSLHttpClient() throws KeyStoreException, NoSuchAlgorithmException, KeyManagementException {

        LogLoader.serverLog.trace("In getSSLHttpClient()");

        SSLContext context = SSLContext.getInstance("SSL");

        TrustManager tm = new X509TrustManager() {
            public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            }

            public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {
            }

            public X509Certificate[] getAcceptedIssuers() {
                return null;
            }
        };

        context.init(null, new TrustManager[] { tm }, null);

        HttpClientBuilder builder = HttpClientBuilder.create();
        SSLConnectionSocketFactory sslConnectionFactory = new SSLConnectionSocketFactory(context);
        builder.setSSLSocketFactory(sslConnectionFactory);

        PlainConnectionSocketFactory plainConnectionSocketFactory = new PlainConnectionSocketFactory();
        Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory>create()
                .register("https", sslConnectionFactory).register("http", plainConnectionSocketFactory).build();

        PoolingHttpClientConnectionManager ccm = new PoolingHttpClientConnectionManager(registry);
        ccm.setMaxTotal(BaseConstant.CONNECTION_POOL_SIZE);
        ccm.setDefaultMaxPerRoute(BaseConstant.CONNECTION_POOL_SIZE);
        builder.setConnectionManager((HttpClientConnectionManager) ccm);

        builder.disableRedirectHandling();

        LogLoader.serverLog.trace("Out getSSLHttpClient()");

        return builder.build();
    }
