java - 如何忽略 Apache HttpComponents HttpClient 5.1 中的 SSL 证书错误

Question

如何绕过 Apache HttpComponents HttpClient 5.1 的证书验证错误?
我找到了 working solution绕过 HttpClient 4.5 中建议自定义 HttpClient 的此类错误实例:

HttpClient httpClient = HttpClients
            .custom()
            .setSSLContext(new SSLContextBuilder().loadTrustMaterial(null, TrustAllStrategy.INSTANCE).build())
            .setSSLHostnameVerifier(NoopHostnameVerifier.INSTANCE)
            .build();

但它不适用于 HttpClient 5.1，如 setSSLContext和 setSSLHostnameVerifier HttpClientBuilder 中不存在方法( HttpClients.custom() 返回)。

HC 5.1 中有几个专门的构建器可以用来做同样的事情:

CloseableHttpClient httpclient = HttpClients.custom()
        .setConnectionManager(PoolingHttpClientConnectionManagerBuilder.create()
                .setSSLSocketFactory(SSLConnectionSocketFactoryBuilder.create()
                        .setSslContext(SSLContextBuilder.create()
                                .loadTrustMaterial(TrustAllStrategy.INSTANCE)
                                .build())
                        .setHostnameVerifier(NoopHostnameVerifier.INSTANCE)
                        .build())
                .build())
        .build();
