Question

我正在尝试从我的应用程序到内部服务器建立SSL连接。我下载了一个包含所有需要的证书和CA的PKCS12文件。然后我将它加载到我用来进行SSL调用的密钥库中。

当我进行SSL调用时，我收到以下异常： java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.

查看android dev website，看起来这是由于未知的证书颁发机构。

到目前为止，这是我的代码：

private void testConnect(String base64Pkcs) {
    KeyStore keyStore;
    SSLContext sslContext = null;
    TrustManager trustManager = null;
    try {
        keyStore = KeyStore.getInstance("PKCS12");
        writeFile(base64Pkcs);
        if (keyStore != null) {
            keyStore.load(readFile(), DEBUG_CERT_PWD.toCharArray());

            KeyManagerFactory keyManagerFactory = KeyManagerFactory.getInstance(TrustManagerFactory.getDefaultAlgorithm());
            keyManagerFactory.init(keyStore, DEBUG_CERT_PWD.toCharArray());
            KeyManager[] keyManagers = keyManagerFactory.getKeyManagers();

            sslContext = SSLContext.getInstance("TLS");
            TrustManagerFactory trustManagerFactory = TrustManagerFactory.getInstance("X509");
            trustManagerFactory.init(keyStore);
            sslContext.init(keyManagers, trustManagerFactory.getTrustManagers(), null);
            trustManager = trustManagerFactory.getTrustManagers()[0];

            OkHttpClient client = new OkHttpClient.Builder()
                    .sslSocketFactory(sslContext.getSocketFactory(), (X509TrustManager) trustManager)
                    .build();

            final Request request = new Request.Builder().url(getApplication().getString(R.string.https_test_endpoint_url)).build();

            client.newCall(request).enqueue(new Callback() {
                @Override
                public void onFailure(Call call, IOException e) {
                    Log.e(TAG, "Error while calling the test secure endpoint", e);
                }

                @Override
                public void onResponse(Call call, Response response) throws IOException {
                    Log.d(TAG, response.message());
                    if (response.body() != null) {
                        Log.d(TAG, response.body().string());
                    }
                }
            });
        }
    } catch (KeyStoreException | IOException | NoSuchAlgorithmException | CertificateException | UnrecoverableKeyException | KeyManagementException e) {
        //TODO: Handle exceptions
        Log.wtf(TAG, e);
    }
}

我可以通过使用openSSL手动从PKCS12文件中提取CA，将其放入我的应用资产并使用以下命令加载来实现连接：

openssl pkcs12 -in tls.pkcs -cacerts -nokeys -chain -out tls.trust - password pass:mydevpassword`
keyStore.setCertificateEntry("ca", myCaCert);`

我的问题是我无法使用我的应用程序中的openSSL导出CA并以编程方式将其加载到密钥库。有没有办法做到这一点，还是我不得不将CA包含在应用资产中？

您是否没有在清单中设置networkSecurityConfig的问题？
