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处理了以前的版本,并且 API 发生了变化。

下面的代码适用于信任自签名证书。创建客户端时,您必须使用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();
}
我没有包括SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER故意:重点是允许使用自签名证书进行测试,因此您不必从证书颁发机构获取适当的证书。您可以轻松地创建具有正确主机名的自签名证书,因此不要添加SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER标志。
如果您使用上面的 PoolingHttpClientConnectionManager 过程不起作用,则会忽略自定义 SSLContext。创建 PoolingHttpClientConnectionManager 时,您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,如果您想信任所有证书而不仅仅是自签名,您会这样做(以您的代码风格)
builder.loadTrustMaterial(null, new TrustStrategy(){
    public boolean isTrusted(X509Certificate[] chain, String authType)
        throws CertificateException {
        return true;
    }
});
或(从我自己的代码中直接复制粘贴):
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();
如果你也想跳过主机名验证,你需要设置
    CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(
            sslsf).setSSLHostnameVerifier( NoopHostnameVerifier.INSTANCE).build();
也是。(不推荐使用 ALLOW_ALL_HOSTNAME_VERIFIER)。
强制性警告:你不应该真的这样做,接受所有证书是一件坏事。但是,您希望在一些罕见的用例中执行此操作。
作为对前面给出的代码的注释,即使 httpclient.execute() 抛出异常,您也需要关闭响应
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();
    }
}
上面的代码是用
<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpclient</artifactId>
    <version>4.5.3</version>
</dependency>

vasekt 对答案的一个小补充:
使用 PoolingHttpClientConnectionManager 时,提供的 SocketFactoryRegistry 解决方案有效。
但是,通过普通 http 的连接不再起作用。您必须另外为 http 协议添加一个 PlainConnectionSocketFactory 才能使它们再次工作:
Registry<ConnectionSocketFactory> socketFactoryRegistry = 
  RegistryBuilder.<ConnectionSocketFactory> create()
  .register("https", sslsf)
  .register("http", new PlainConnectionSocketFactory()).build();
    在尝试了各种选项后,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);
CloseableHttpClient httpClient = HttpClients.custom()
                .setSSLSocketFactory(sslsf)
                .setConnectionManager(cm)
                .build();
我正在使用 http-client 4.3.3 :compile 'org.apache.httpcomponents:httpclient:4.3.3'
更简单和更短的工作代码:
我们使用的是HTTPClient 4.3.5,我们尝试了stackoverflow上几乎所有的解决方案,但没有,在思考并找出问题后,我们得出以下完美运行的代码,只需在创建HttpClient实例之前添加它。
您用来发出发布请求的一些方法...
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();
    HttpPost postRequest = new HttpPost(url);
继续以正常形式调用和使用 HttpPost 实例
这是上述技术的一个工作提炼,相当于“curl --insecure”:
HttpClient getInsecureHttpClient() throws GeneralSecurityException {
    TrustStrategy trustStrategy = new TrustStrategy() {
        @Override
        public boolean isTrusted(X509Certificate[] chain, String authType) {
            return true;
        }
    };
    HostnameVerifier hostnameVerifier = new HostnameVerifier() {
        @Override
        public boolean verify(String hostname, SSLSession session) {
            return true;
        }
    };
    return HttpClients.custom()
            .setSSLSocketFactory(new SSLConnectionSocketFactory(
                    new SSLContextBuilder().loadTrustMaterial(trustStrategy).build(),
                    hostnameVerifier))
            .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);
        }
    }

    如果您正在使用HttpClient 4.5.x,您的代码可能类似于以下内容:
SSLContext sslContext = new SSLContextBuilder().loadTrustMaterial(null,
        TrustSelfSignedStrategy.INSTANCE).build();
SSLConnectionSocketFactory sslSocketFactory = new SSLConnectionSocketFactory(
        sslContext, NoopHostnameVerifier.INSTANCE);
HttpClient httpClient = HttpClients.custom()
                                   .setDefaultCookieStore(new BasicCookieStore())
                                   .setSSLSocketFactory(sslSocketFactory)
                                   .build();
    
如果您想要使用代码的异步httpclient PoolingHttpClientConnectionManager,则应类似于以下内容Registry<ConnectionSocketFactory> socketFactoryRegistry = RegistryBuilder.<ConnectionSocketFactory> create().register("https", sslFactory).build();PoolingNHttpClientConnectionManager
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();
SchemeIOSessionStrategy sslioSessionStrategy = new SSLIOSessionStrategy(sslContext, 
                new HostnameVerifier(){
            @Override
            public boolean verify(String hostname, SSLSession session) {
                return true;// TODO as of now allow all hostnames
            }
        });
Registry<SchemeIOSessionStrategy> sslioSessionRegistry = RegistryBuilder.<SchemeIOSessionStrategy>create().register("https", sslioSessionStrategy).build();
PoolingNHttpClientConnectionManager ncm  = new PoolingNHttpClientConnectionManager(new DefaultConnectingIOReactor(),sslioSessionRegistry);
CloseableHttpAsyncClient asyncHttpClient = HttpAsyncClients.custom().setConnectionManager(ncm).build();
asyncHttpClient.start();        
    (我会直接在 vasekt 的答案中添加评论,但我没有足够的声誉点(不确定那里的逻辑)
无论如何...我想说的是,即使您没有明确创建/请求 PoolingConnection,也不意味着您没有得到一个。
我疯狂地试图弄清楚为什么最初的解决方案对我不起作用,但我忽略了 vasekt 的回答,因为它“不适用于我的情况”——错了!
我在低时盯着我的堆栈跟踪,发现我在它中间看到了一个 PoolingConnection。Bang - 我厌倦了他的加入和成功!(我们的演示是明天,我越来越绝望):-)
信任 Apache HTTP 客户端中的所有证书
TrustManager[] trustAllCerts = new TrustManager[]{
                    new X509TrustManager() {
                        public java.security.cert.X509Certificate[] getAcceptedIssuers() {

                SSLContext sc = SSLContext.getInstance("SSL");
                sc.init(null, trustAllCerts, new java.security.SecureRandom());
                SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
                        sc);
                httpclient = HttpClients.custom().setSSLSocketFactory(
                        sslsf).build();
                HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
    您可以使用以下代码片段来获取 HttpClient 实例,而无需进行 ssl 认证检查。

    }
    对上面@divbyzero 的回答稍作调整,以修复声纳安全警告
CloseableHttpClient getInsecureHttpClient() throws GeneralSecurityException {
            TrustStrategy trustStrategy = (chain, authType) -> true;
            HostnameVerifier hostnameVerifier = (hostname, session) -> hostname.equalsIgnoreCase(session.getPeerHost());
            return HttpClients.custom()
                    .setSSLSocketFactory(new SSLConnectionSocketFactory(new SSLContextBuilder().loadTrustMaterial(trustStrategy).build(), hostnameVerifier))
                    .build();
        }
    最初,我能够使用信任策略禁用 localhost,后来我添加了 NoopHostnameVerifier。现在它将适用于 localhost 和任何机器名称
SSLContext sslContext = SSLContextBuilder.create().loadTrustMaterial(null, new TrustStrategy() {
            @Override
            public boolean isTrusted(X509Certificate[] chain, String authType) throws CertificateException {
                return true;
            }
        }).build();
        SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
                sslContext, NoopHostnameVerifier.INSTANCE);
        CloseableHttpClient httpclient = HttpClients.custom().setSSLSocketFactory(sslsf).build();
