改进HTTPS连接无法在Android中运行

Posted 2021-04-07

我收到了一个信任锚错误。我尝试使用http://www.snip2code.com/Snippet/25364/Get-OkHttpClient-which-ignores-all-SSL-e进行https连接，但这会返回错误。

 D/Retrofit﹕ javax.net.ssl.SSLHandshakeException: java.security.cert.CertPathValidatorException: Trust anchor for certification path not found.
        at com.android.org.conscrypt.OpenSSLSocketImpl.startHandshake(OpenSSLSocketImpl.java:328)

答案

尝试使用以下示例代码：

    private TrustManager[] getWrappedTrustManagers(TrustManager[] trustManagers) {
        final X509TrustManager originalTrustManager = (X509TrustManager) trustManagers[0];
        return new TrustManager[]{
                new X509TrustManager() {
                    public X509Certificate[] getAcceptedIssuers() {
                        return originalTrustManager.getAcceptedIssuers();
                    }
                    public void checkClientTrusted(X509Certificate[] certs, String authType) {
                        try {
                            originalTrustManager.checkClientTrusted(certs, authType);
                        } catch (CertificateException ignored) {
                        }
                    }
                    public void checkServerTrusted(X509Certificate[] certs, String authType) {
                        try {
                            originalTrustManager.checkServerTrusted(certs, authType);
                        } catch (CertificateException ignored) {
                        }
                    }
                }
        };
    }

    private SSLSocketFactory getSSLSocketFactory()
            throws CertificateException, KeyStoreException, IOException,
                    NoSuchAlgorithmException, KeyManagementException {
        CertificateFactory cf = CertificateFactory.getInstance("X.509");
        InputStream caInput = getResources().openRawResource(R.raw.your_cert); // your certificate file
        Certificate ca = cf.generateCertificate(caInput);
        caInput.close();
        KeyStore keyStore = KeyStore.getInstance("BKS");
        keyStore.load(null, null);
        keyStore.setCertificateEntry("ca", ca);
        String tmfAlgorithm = TrustManagerFactory.getDefaultAlgorithm();
        TrustManagerFactory tmf = TrustManagerFactory.getInstance(tmfAlgorithm);
        tmf.init(keyStore);
        TrustManager[] wrappedTrustManagers = getWrappedTrustManagers(tmf.getTrustManagers());
        SSLContext sslContext = SSLContext.getInstance("TLS");
        sslContext.init(null, wrappedTrustManagers, null);
        return sslContext.getSocketFactory();
    }

然后，您可以在项目中设置OkHttpClient，如下所示：

okHttpClient.setSslSocketFactory(getSSLSocketFactory());

关于setHostnameVerifier，看起来你的问题链接中有一个解决方案。

希望这可以帮助！
