HttpClient 4.3.x，修复不推荐使用的代码以使用当前的 HttpClient 实现

Question

我有以下代码，它仍然可以编译，但它们都已弃用：

SSLSocketFactory sslSocketFactory = new SSLSocketFactory(context, SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
ClientConnectionManager clientConnectionManager = base.getConnectionManager();
SchemeRegistry schemeRegistry = clientConnectionManager.getSchemeRegistry();
schemeRegistry.register(new Scheme("https", 443, sslSocketFactory));
return new DefaultHttpClient(clientConnectionManager, base.getParams());

我尽力用这部分代码替换它：

HttpClientBuilder builder = HttpClientBuilder.create();
SSLConnectionSocketFactory sslConnectionFactory = new SSLConnectionSocketFactory(context, SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
builder.setConnectionManager(new BasicHttpClientConnectionManager());
builder.setSSLSocketFactory(sslConnectionFactory);
return builder.build();

如您所见，顶帖中的几行代码我不知道如何包含在新部分中。 如何添加所需的代码，例如备用SchemeRegistry ？

Answer 1

我还不能发表评论，但这里是 herau 答案的一个小升级，因为它自 4.4 以来已被弃用，也许有人会发现它很有用。

SSLConnectionSocketFactory sslConnectionFactory = new SSLConnectionSocketFactory(context, NoopHostnameVerifier.INSTANCE);

Answer 2

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

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

HttpClientConnectionManager ccm = new BasicHttpClientConnectionManager(registry);

builder.setConnectionManager(ccm);

return builder.build();

正如手册所说，我已将库替换为 NoopH​​ostnameVerifier 并像这样使用它：

    private static CloseableHttpClient client =
        HttpClients.custom().setSSLHostnameVerifier(new NoopHostnameVerifier()).build();
