Question

我有一个应用程序，用于使用和更新数据到网络服务器，最近，由于存储了个人信息，应用程序所有者决定切换到安全连接。

服务器已经设置为SNI，我已经使用digicert进行了检查，服务器工作正常并且似乎设置正确，但不包含路径* .host.com的替代名称（我不确定SNI是否正常）。

iOS的工作就像一个魅力，但在Android上我得到了这个错误：

java.security.cert.CertPathValidatorException：找不到证书路径的信任锚。

我目前的连接方法如下：

    URL url = new URL(postURL);
    HttpsURLConnection conn = (HttpsURLConnection) url.openConnection();
    SSLContext sc;
    sc = SSLContext.getInstance("TLS");

    sc.init(null, null, new java.security.SecureRandom());
    conn.setSSLSocketFactory(sc.getSocketFactory());

    String userpass = "bob" + ":" + "12345678";
    String basicAuth = "Basic " + Base64.encodeToString(userpass.getBytes(), Base64.DEFAULT);
    conn.setRequestProperty("Authorization", basicAuth);

    conn.setReadTimeout(7000);
    conn.setConnectTimeout(7000);
    conn.setRequestMethod("POST");
    conn.setDoInput(true);

    conn.connect();

    InputStream instream = conn.getInputStream();
    BufferedReader reader = new BufferedReader(new InputStreamReader(instream));

    StringBuilder everything = new StringBuilder();
    String line;

    while ((line = reader.readLine()) != null) {
        everything.append(line);
    }

    JSONObject jsonObject = new JSONObject(everything.toString());

    return jsonObject;

我不太确定这里的问题是什么，但尝试连接到https://sni.velox.ch/给了我一个似乎成功的长答案。

另外，我这里有证书的pem密钥，但我不知道在这种情况下我是如何添加的。

通常在使用自签名证书时会出现此错误，在这种情况下，您必须在提出请求时使用证书。

此外，由于未包含路径 *。host.com ，您可能会收到此错误。

您可以在构建HttpsURLConnection时尝试使用以下代码传递证书。请不要忘记将 ca.pem 文件复制到assets文件夹。

private HttpsURLConnection buildSslServerConnection() {
    HttpsURLConnection urlConnection = null;
    try {
        // Load CAs from an InputStream
        CertificateFactory cf = CertificateFactory.getInstance("X.509");
        InputStream caInput = new BufferedInputStream(context.getAssets().open("ca.pem"));
        Certificate ca;
        try {
            ca = cf.generateCertificate(caInput);
        } finally {
            caInput.close();
        }

        // Create a KeyStore containing our trusted CAs
        String keyStoreType = KeyStore.getDefaultType();
        KeyStore keyStore = KeyStore.getInstance(keyStoreType);
        keyStore.load(null, null);
        keyStore.setCertificateEntry("ca", ca);

        // Create a TrustManager that trusts the CAs in our KeyStore
        String tmfAlgorithm = TrustManagerFactory.getDefaultAlgorithm();
        TrustManagerFactory tmf = TrustManagerFactory.getInstance(tmfAlgorithm);
        tmf.init(keyStore);

        // Create an SSLContext that uses our TrustManager
        SSLContext context = SSLContext.getInstance("TLS");
        context.init(null, tmf.getTrustManagers(), null);

        // Tell the URLConnection to use a SocketFactory from our SSLContext
        urlConnection = (HttpsURLConnection) url.openConnection();
        urlConnection.setSSLSocketFactory(context.getSocketFactory());
        urlConnection.setRequestMethod("POST");
        urlConnection.setRequestProperty("Authorization", "Basic" + Base64.encodeToString(userpass.getBytes(), Base64.DEFAULT));
        urlConnection.setConnectTimeout(7000);
        urlConnection.setReadTimeout(7000);
        urlConnection.setInstanceFollowRedirects(false);
        urlConnection.setUseCaches(false);
        urlConnection.setAllowUserInteraction(false);
        urlConnection.setDoOutput(false);
    } catch (KeyManagementException e) {
        LOG.error("Error while checking server connectivity: ", e);
    } catch (CertificateException e) {
        LOG.error("Error while checking server connectivity: ", e);
    } catch (FileNotFoundException e) {
        LOG.error("Error while checking server connectivity: ", e);
    } catch (KeyStoreException e) {
        LOG.error("Error while checking server connectivity: ", e);
    } catch (NoSuchAlgorithmException e) {
        LOG.error("Error while checking server connectivity: ", e);
    } catch (MalformedURLException e) {
        LOG.error("Error while checking server connectivity: ", e);
    } catch (IOException e) {
        LOG.error("Error while checking server connectivity: ", e);
    }
    return urlConnection;
}

希望这有帮助。
