カスタムTrustManagerを使用したAndroidのSSLWebサイトの証明書が信頼されていません

user4424299

私のアプリはhttps経由で自分のWebサイト（有効なLet's Encryption証明書を使用）に接続しますが、Androidは証明書を信頼していません。この例外が発生します。

自分の証明書（https://developer.android.com/training/articles/security-ssl.html）を受け入れてこの問題を修正するための公式Androidガイドに従いましたが、問題は解決していません。

今、私はこの問題をデバッグして、Androidが私のウェブサイトから抽出した証明書と私がそれに渡す証明書を印刷しようとしましたが、それらは同じです！それでも不平を言い、証明書を信頼できないのはどうしてですか？

これは私のコードです:

public String getJSON(String store, Context context) throws IOException, LogoNotFoundException {
        try {
            // Load CAs from an InputStream
            CertificateFactory cf = CertificateFactory.getInstance("X.509");
            InputStream caInput = new BufferedInputStream(context.getResources().openRawResource(R.raw.abyx));
            Certificate ca;
            try {
                ca = cf.generateCertificate(caInput);
                System.out.println("ca=" + ((X509Certificate) ca).getSubjectDN());
            } 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 sslContext = SSLContext.getInstance("TLS");
            sslContext.init(null, tmf.getTrustManagers(), null);

            store = URLEncoder.encode(store, "UTF-8");
            String response;
            URL url = new URL("https://www.abyx.be/loyalty/public/logo/" + URLEncoder.encode(store, "utf-8"));
            HttpsURLConnection connection = (HttpsURLConnection) url.openConnection();
            connection.setSSLSocketFactory(sslContext.getSocketFactory());
            connection.connect();
            Certificate[] certificates = connection.getServerCertificates();
            for (Certificate cert: certificates) {
                System.out.println(cert);
            }
            connection.setRequestMethod("GET");
            int statusCode = connection.getResponseCode();
            if (statusCode == 200) {
                InputStream in = new BufferedInputStream(connection.getInputStream());
                response = IOUtils.toString(in, "UTF-8");
            } else if (statusCode == 404) {
                throw new LogoNotFoundException();
            } else {
                throw new IOException("Unable to connect to Loyalty API!");
            }
            return response;
        } catch (KeyStoreException | NoSuchAlgorithmException | KeyManagementException | CertificateException e) {
            throw new IOException(e);
        }
    }

これは私が接続しようとしているウェブサイトです：https：//abyx.be

私が間違ったことをしたかもしれないことについて何か考えはありますか？

これは私の証明書です：

そして、これはを使用してデコードされた証明書openssl x509です。

Apacheサーバーの構成でエラーが発生しました。SSLLabsによると、サーバーの証明書チェーンが不完全です。

サーバー構成には、次の行が含まれている必要があります。

SSLCertificateFile /etc/letsencrypt/live/$DOMAIN/cert.pem
SSLCertificateKeyFile /etc/letsencrypt/live/$DOMAIN/privkey.pem
SSLCertificateChainFile /etc/letsencrypt/live/$DOMAIN/chain.pem

3行目は重要です。クライアントにチェックするための完全な証明書チェーンを提供します。
