任何人都可以帮助我开始在Java中执行带有服务器名称指示的HTTP连接吗？
我正在尝试从我正在管理的网站请求内容。我一直在使用Apache的HttpClient库，但我对安全内容的请求失败了，因为该网站只使用SNI作为HTTPS，并且SNI没有在DefaultHttpClient中启用。我已经在Apache的HttpClient库中寻找了有关如何解决这个问题的说明，但是我看到最终得到了这个文档：http://hc.apache.org/httpclient-3.x/sslguide.html，它已经过时了（指的是当HttpClient和HttpCore是Apache的commons包的一部分时的代码）。
所以。。。任何帮助？
您可能希望跟踪 https://issues.apache.org/jira/browse/HTTPCLIENT-1119
Java 7的底层客户端实现能够支持它，并通过SSSocketImpl#setHost（由sun.net.www.protocol.https.https调用）公开该功能。
在 Java 7 上使用
new URL("https://cmbntr.sni.velox.ch/").openStream()
直到 HTTPCLIENT-1119 被修复
这就是我在 org.apache.httpcomponents 的 httpclient v4.3+ 中所做的。
private HttpClientConnectionManager createConnectionManager(final SSLContext ctx) {
LOG.info("Creating sslConnectionSocketFactory");
final SSLConnectionSocketFactory sslSF = new SSLConnectionSocketFactory(ctx) {
@Override
protected void prepareSocket(SSLSocket socket) throws IOException {
try {
System.out.println("************ setting socket HOST property *************");
PropertyUtils.setProperty(socket, HOST, Constants.SNI_HOST);
} catch (IllegalAccessException | NoSuchMethodException | InvocationTargetException ex) {
LOG.error(ex.getMessage());
}
super.prepareSocket(socket);
}
};
LOG.info("Creating connectionRegistry");
final Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory>create()
.register("https", sslSF)
.build();
LOG.info("Creating poolingConnectionManager");
final PoolingHttpClientConnectionManager connectionManager = new PoolingHttpClientConnectionManager(registry);
connectionManager.setDefaultMaxPerRoute(MAX_CONNECTIONS_PER_ROUTE);
connectionManager.setMaxTotal(MAX_CONNECTIONS);
return connectionManager;
}
这就是我如何创建HttpClient
final KeyManager[] keyManagers = createKeyManagers();
final TrustManager[] trustManagers = createTrustManagers();
final SSLContext ctx = createSslContext(keyManagers, trustManagers);
final HttpClientConnectionManager connectionManager = createConnectionManager(ctx);
LOG.info("Creating httpClient");
HttpClient httpClient = HttpClients
.custom()
.setConnectionManager(connectionManager)
.build();
