        try {

使用okhttp

private final OkHttpClient client = new OkHttpClient().newBuilder()
            .sslSocketFactory(SSLSocketClient.getSSLSocketFactory(), SSLSocketClient.getX509TrustManager())
            .hostnameVerifier(SSLSocketClient.getHostnameVerifier())
            .connectTimeout(60, TimeUnit.SECONDS).build();
