Android OKHTTP发起请求提示：SSLException: Unable to parse TLS packet header

今天切换环境进行调试，某一个接口突然出现报错：

javax.net.ssl.SSLException: Unable to parse TLS packet header

at com.Android.org.conscrypt.ConscryptEngine.unwrap(ConscryptEngine.java:807)

at com.android.org.conscrypt.ConscryptEngine.unwrap(ConscryptEngine.java:747)

at com.android.org.conscrypt.ConscryptEngine.unwrap(ConscryptEngine.java:712)

at com.android.org.conscrypt.ConscryptEngineSocket$SSLInputStream.processDataFromSocket(ConscryptEngineSocket.java:858)

看到SSLException，心里第一个想法：简单，肯定是https协议没有增加SSL校验。

private SSLSocketFactory createSSLSocketFactory() {        SSLSocketFactory ssfFactory = null;        try {            SSLContext sc = SSLContext.getInstance("TLS");            sc.init(null, new TrustManager[]{mMyTrustManager}, new SecureRandom());            ssfFactory = sc.getSocketFactory();        } catch (Exception ignored) {            ignored.printStackTrace();        }        return ssfFactory;    }

 //实现X509TrustManager接口    public class MyTrustManager implements 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];        }    }

创建

new OkHttpClient.Builder()                    .connectTimeout(50000, TimeUnit.MILLISECONDS)                    .readTimeout(50000, TimeUnit.MILLISECONDS)                    .writeTimeout(50000, TimeUnit.MILLISECONDS)                    .sslSocketFactory(createSSLSocketFactory(), new MyTrustManager())                    .addInterceptor(new SameRequestFilterInterceptor())                    .retryOnConnectionFailure(true).build();

运行，还是报错Unable to parse TLS packet header。

见鬼了，切换到正式环境就没有问题，难道是后台的锅？【别管是不是，先把锅抛出去！】

灵光一闪，SSL是HTTPS引起的，询问后台新环境是HTTP还是HTTPS。得到结果是http。

果然是这样，将https，修改为http，运行——成功！
