HttpClient 4.3.x，修復不推薦使用的代碼以使用當前的 HttpClient 實現

Question

我有以下代碼，它仍然可以編譯，但它們都已棄用：

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());

我盡力用這部分代碼替換它：

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

如您所見，頂帖中的幾行代碼我不知道如何包含在新部分中。 如何添加所需的代碼，例如備用SchemeRegistry ？

Answer 1

我還不能發表評論，但這里是 herau 答案的一個小升級，因為它自 4.4 以來已被棄用，也許有人會發現它很有用。

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();

Answer 3

正如手冊所說，我已將庫替換為 NoopH​​ostnameVerifier 並像這樣使用它：

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