从httpclient4迁移到httpclient5 - 无法使用setSSLContext

Question

我们正在尝试将 httpclient 从 4 升级到 5。作为升级的一部分，我们相应地更改了导入。但是，代码使用 Httpclientbuilder 并设置 sslcontext。 根据 apache 的文档，他们已从 Httpclientbuilder 方法中删除了 setsslcontext，但我没有找到任何替代方案。

错误提示 HttpClientBuilder 类型未定义 setSSLContext(sslcontext) 方法。

代码如下：

import org.apache.hc.client5.http.classic.HttpClient;
import org.apache.hc.client5.http.impl.classic.HttpClientBuilder;

SSLContext sslcontext = SSLContext.getDefault();
HttpClient httpclient = HttpClientBuilder.create().setSSLContext(sslcontext).build();
ClientHttpRequestFactory reqFac = new HttpComponentsClientHttpRequestFactory(httpclient);

Answer 1

这是我们使用的替代品：

HttpClientBuilder clientBuilder = HttpClients.custom();
final SSLContext sslContext = createSslContext();
final ConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(sslContext, new DefaultHostnameVerifier());
final Registry<ConnectionSocketFactory> socketFactoryRegistry =
                    RegistryBuilder.<ConnectionSocketFactory> create()
                            .register("https", sslsf)
                            .register("http", new PlainConnectionSocketFactory())
                            .build();
final BasicHttpClientConnectionManager connectionManager = new BasicHttpClientConnectionManager(socketFactoryRegistry);
clientBuilder.setConnectionManager(connectionManager);
