将 Apache HttpComponents 用于 https 请求："peer not authenticated"和"handshake_failure"错误

Question

我正在尝试使用 Apache HttpComponents 库对 JBoss 服务器进行 HTTP GET 调用。当我使用 http URL 执行此操作时，它工作正常，但是当我使用 https URL 时，它不起作用。这是我的代码：

public static String HttpGET(String requestURL, Cookie cookie)
        throws HttpException {
    DefaultHttpClient httpClient = new DefaultHttpClient();
    if (cookie != null) {
        CookieStore store = new BasicCookieStore();
        store.addCookie(cookie);
        ((AbstractHttpClient) httpClient).setCookieStore(store);
    }
    HttpGet httpGet = new HttpGet(requestURL);
    HttpResponse response = null;
    HttpEntity responseEntity = null;
    String responseBody = null;
    try {
        response = httpClient.execute(httpGet);
        // Do some more stuff...
    } catch (SSLPeerUnverifiedException ex) {
        // Message "peer not authenticated" means the server presented
        // a certificate that was not found in the local truststore.
        throw new HttpException("HTTP GET request failed; possible"
                + " missing or invalid certificate: " + ex.getMessage());
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        // When HttpClient instance is no longer needed,
        // shut down the connection manager to ensure
        // immediate deallocation of all system resources
        httpClient.getConnectionManager().shutdown();
    }
    return responseBody;
}

当我execute()我的GET电话时，我得到了一个SSLPeerUnverifiedException。错误消息是：

javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated

经过一些广泛的谷歌搜索和搜索StackOverflow问题，我一直看到这个建议，所以我在我的DefaultHttpClient周围添加了这个包装器，如下所示：

private static HttpClient wrapClient(HttpClient httpClient) {       
    try {
        SSLContext ctx = SSLContext.getInstance("TLS");
        X509TrustManager tm = new X509TrustManager() {
            public void checkClientTrusted(X509Certificate[] xcs,
                    String string) {
            }
            public void checkServerTrusted(X509Certificate[] xcs,
                    String string) {
            }
            public X509Certificate[] getAcceptedIssuers() {
                return null;
            }
        };
        X509HostnameVerifier verifier = new X509HostnameVerifier() {
            @Override
            public boolean verify(String hostname, SSLSession session) {
                return false;
            }
            @Override
            public void verify(String arg0, SSLSocket arg1)
                    throws IOException { }
            @Override
            public void verify(String arg0, X509Certificate arg1)
                    throws SSLException { }
            @Override
            public void verify(String arg0, String[] arg1, String[] arg2)
                    throws SSLException { }
        };
        ctx.init(null, new TrustManager[] { tm }, null);
        SSLSocketFactory socketFactory = new SSLSocketFactory(ctx);
        socketFactory.setHostnameVerifier(verifier);
        Scheme sch = new Scheme("https", 443, socketFactory);
        httpClient.getConnectionManager().getSchemeRegistry().register(sch);
        return httpClient;
    } catch (Exception ex) {
        ex.printStackTrace();
        return null;
    }
}

但是，这只会产生不同的错误：

javax.net.ssl.SSLHandshakeException: Received fatal alert: handshake_failure

我相信证书设置正确，因为使用 Jersey 库编写的其他代码可以成功连接到此服务器。但是，我没有看到我在Apache HttpComponents上做错了什么。有什么想法吗？如果我犯了明显的错误，我深表歉意，我是SSL的新手，还没有完全了解我在做什么。感谢您的任何帮助！

Answer 1

这可能是由于您的服务器需要服务器名称指示。

由于Apache HTTP Client 4.2.2似乎不支持SNI（即使使用Java 7，它也不会发送server_name扩展），因此您可能会获得与使用SNI的其他库不同的证书。

似乎有一种方法可以在Apache HTTP Client 4.3中获得SNI支持（但至少你仍然需要Java 7）。
