sslContext is missing from the options

[Jonathanide1]

This seems to have been removed in 1.x onwards - how are we supposed to set up an SSL context without it when we migrate to 1.x or later? Any help appreciated. BTW This is for an Android client that is migrating from 0.8x.

try it.

// option is  IO.Options()
option.webSocketFactory = OKHttpClientTrustAll().getOKHttpClientTrustAll(OkHttpClient.Builder())

public OkHttpClient getOKHttpClientTrustAll(OkHttpClient.Builder builder) {
        builder.hostnameVerifier(new HostnameVerifier() {
            @Override
            public boolean verify(String hostname, SSLSession session) {
                return true;
            }
        });

        SSLContext sslcontext = null;

        try {
            sslcontext = SSLContext.getInstance("TLS");
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        }

        try {
            sslcontext.init(null, trustManagers, null);
        } catch (KeyManagementException e) {
            e.printStackTrace();
        }

        SSLEngine sslEngine = sslcontext.createSSLEngine();
        sslEngine.setUseClientMode(false);
        sslEngine.setNeedClientAuth(false);

        builder.sslSocketFactory(sslcontext.getSocketFactory(), new X509TrustManager() {
            @Override
            public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException {

            }

            @Override
            public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException {

            }

            @Override
            public X509Certificate[] getAcceptedIssuers() {
                return new X509Certificate[0];
            }
        });
        return builder.build();
    }

    TrustManager[] trustManagers = new TrustManager[]{
            new X509TrustManager() {
                @Override
                public void checkClientTrusted(X509Certificate[] chain, String authType) {
                }

                @Override
                public void checkServerTrusted(X509Certificate[] chain, String authType) {
                }

                @Override
                public X509Certificate[] getAcceptedIssuers() {
                    return new X509Certificate[0];
                }
            }
    };
