原始HTTPS在没有回复的情况下跳过Java

Question

我试图在Java不使用外部库或HttpURLConnection类的情况下通过SSL Socket进行快速HTTP GET，并注意到结果因使用的HTTP服务器类型而异。

以下是主要的Java代码：

    private static SSLContext context = null;
    private static KeyStore keystore = null;
    private static SSLSocketFactory sslClientSockFactory = null;
    private static KeyManagerFactory kmFactory = null;
    private static KeyManager[] keyMan = null;
    private static TrustManager[] trustMan = null;
    private static int portNum = 443;
    private static String address = "www.google.com";
    protected static final String sslContext = "TLSv1.2";
    private static OutputStream sockOS = null;
    private static InputStream sockIS = null;

    public static void main(String[] args) {
        try {
            // Load HTTPS keystore from nothing
            keystore = KeyStore.getInstance(KeyStore.getDefaultType());
            keystore.load(null, null);
            kmFactory = KeyManagerFactory.getInstance("PKIX");
            kmFactory.init(keystore, null);
            keyMan = kmFactory.getKeyManagers();
            trustMan = new TrustManager[] { new TrustedTrustManager() };
            context = SSLContext.getInstance(sslContext);
            context.init(keyMan, trustMan, null);
            sslClientSockFactory = context.getSocketFactory();

            // Open HTTPS socket
            System.out.println("Attempting to open client ssl sock: " + address + ":" + portNum);
            if (sslClientSockFactory == null) {
                System.out.println("[ERR] Client socket factory is NULL !!!");
            }
            SSLSocket socket = (SSLSocket) sslClientSockFactory.createSocket(address, portNum);

            boolean isConnected = socket.isConnected();
            System.out.println("Is Connected: " + isConnected);
            System.out.println("Is Closed: " + socket.isClosed());
            System.out.println("Is InputShutdown: " + socket.isInputShutdown());
            System.out.println("Is OutputShutdown: " + socket.isOutputShutdown());

            if (isConnected) {    
                String reqStr = "GET / HTTP/1.1\r\n"
                        + "Host: www.google.com\r\n"
                        + "User-Agent: curl/7.79.1\r\n"
                        + "Accept: */*\r\n\r\n";
                
                sockOS = socket.getOutputStream();
                sockIS = socket.getInputStream();
                
                sockOS.write(reqStr.getBytes());
                sockOS.flush();
                    
                byte[] response = sockIS.readAllBytes();
                System.out.println("Response Len: " + response.length);
                socket.close();
            } else {
                System.out.println("[ERR] Failed to connect to destination server ...");
            }
        } catch (KeyStoreException | NoSuchAlgorithmException | CertificateException | IOException
                | UnrecoverableKeyException | KeyManagementException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

对于TrustedTrustManager代码：

public class TrustedTrustManager implements X509TrustManager {

    @Override
    public X509Certificate[] getAcceptedIssuers() {
        return null;
    }

    @Override
    public void checkClientTrusted(java.security.cert.X509Certificate[] certs,
            String authType) {
    }

    @Override
    public void checkServerTrusted(java.security.cert.X509Certificate[] certs,
            String authType) {
    }   
}

不知何故，我可以访问几个lighttpd托管的网页，但这并没有扩展到谷歌和许多其他类型的服务器。

成功查询lighttpd自己主页的一个示例：

如果您知道我的代码缺少什么，从而使它可以在lighttpd托管的服务器上工作，而不能在其他类型的服务器上工作，我们将不胜感激。

找到了答案。这是一个简单的解决方案。

谢谢你的-1。
