忽略Apache HTTPClient 4.5中的自签名证书

Question

• 忽略Apache HttpClient 4.3中的SSL证书
• 如何忽略Apache HttpClient 4.0中的SSL证书错误
• 使用Java忽略SSL证书错误
• 在使用Spring进行开发时需要信任所有证书
• 如何使用Apache HttpClient处理无效的SSL证书？

请注意，在所有这些示例中，我还传递了一个cookie存储区和一个我前面定义的代理凭据提供者。这些是工作的，我只是试图添加SSL支持。

使用SSLContextBuilder创建我自己的ssl上下文，并使用TrustSelfSignedStrategy信任所有自签名策略。

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

CloseableHttpClient httpclient = HttpClients.custom()
    .setDefaultCredentialsProvider(credsProvider)
    .setDefaultCookieStore(cookieStore)
    .setSSLSocketFactory(sslsf)
    .build();

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

CloseableHttpClient httpclient = HttpClients.custom()
    .setDefaultCredentialsProvider(credsProvider)
    .setDefaultCookieStore(cookieStore)
    .setSSLSocketFactory(sslsf)
    .setConnectionManager(cm)
    .build();

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);

CloseableHttpClient httpclient = HttpClients.custom()
    .setDefaultCredentialsProvider(credsProvider)
    .setDefaultCookieStore(cookieStore)
    .setSSLSocketFactory(sslsf)
    .build();

SSLContext sslcontext = SSLContexts.createSystemDefault();
SSLConnectionSocketFactory sslConnectionSocketFactory = new SSLConnectionSocketFactory(
        sslcontext, new String[] { "TLSv1", "SSLv3" }, null,
        SSLConnectionSocketFactory.getDefaultHostnameVerifier());

Registry<ConnectionSocketFactory> socketFactoryRegistry = RegistryBuilder.<ConnectionSocketFactory>create()
        .register("http", PlainConnectionSocketFactory.INSTANCE)
        .register("https", sslConnectionSocketFactory)
        .build();
PoolingHttpClientConnectionManager cm = new PoolingHttpClientConnectionManager(socketFactoryRegistry);

httpclient = HttpClients.custom()
    .setDefaultCredentialsProvider(credsProvider)
    .setDefaultCookieStore(cookieStore)
    .setSSLSocketFactory(sslConnectionSocketFactory)
    .setConnectionManager(cm)
    .build();

上述方法中的一种应该适用于自签名证书，但奇怪的是，所有方法都出现了相同的异常。

我感觉在SSL会话建立或握手协议不被客户机或服务器接受。

这里最好的解决方案是调试应用程序。

//For HTTPS
HttpHost httpstarget = new HttpHost("mysite.com", 443, "https");

//For HTTP
HttpHost httptarget = new HttpHost("mysite.com", 80, "http");
