调用

        mOkHttpClient.setSslSocketFactory(MyApplication.getInstance().getSSLSocketFactory());//配置https证书
        mOkHttpClient.setHostnameVerifier(new HostnameVerifier() {
            @Override
            public boolean verify(String s, SSLSession sslSession) {
                return true;
            }
        });
