Get OkHttpClient which ignores all SSL errors.

GagSsl.java

private static OkHttpClient getUnsafeOkHttpClient() {
    try {
        // Create a trust manager that does not validate certificate chains
        final TrustManager[] trustAllCerts = new TrustManager[]{
                new X509TrustManager() {
                    @Override
                    public void checkClientTrusted(java.security.cert.X509Certificate[] chain,
                                                   String authType) throws CertificateException {
                    }

                    @Override
                    public void checkServerTrusted(java.security.cert.X509Certificate[] chain,
                                                   String authType) throws CertificateException {
                    }

                    @Override
                    public java.security.cert.X509Certificate[] getAcceptedIssuers() {
                        return new X509Certificate[0];
                    }
                }
        };

        // Install the all-trusting trust manager
        final SSLContext sslContext = SSLContext.getInstance("SSL");
        sslContext.init(null, trustAllCerts, new java.security.SecureRandom());
        // Create an ssl socket factory with our all-trusting manager
        final SSLSocketFactory sslSocketFactory = sslContext.getSocketFactory();

        return new OkHttpClient.Builder()
                .sslSocketFactory(sslSocketFactory, (X509TrustManager) trustAllCerts[0])
                .hostnameVerifier(new HostnameVerifier() {
                    @Override
                    public boolean verify(String hostname, SSLSession session) {
                        return true;
                    }
                }).build();

    } catch (Exception e) {
        throw new RuntimeException(e);
    }
}

Is there a way to write this in version okhttp 2.7.5? OkHttpClient does not have a Builder in that version.

I replaced the return statement with these lines:

            OkHttpClient client = new OkHttpClient();
            client.setSocketFactory(sslSocketFactory);
            client.setHostnameVerifier(
                    new HostnameVerifier() {
                        @Override
                        public boolean verify(String hostname, SSLSession session) {
                            return true;
                        }
                    }
            );
            return client;

It seems like OkHttpClient does not have aX509TrustManager field in version 2.7.5, so I omitted it.
