Android OKHTTP initiates a request prompt: SSLException: Unable to parse TLS packet header

Today, I switched the environment for debugging, and a certain interface suddenly reported an error:

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)

Seeing SSLException, the first thought in my heart: simple, it must be that the HTTPS protocol has not added SSL verification.

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];
        }
    }

create

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();

Running, still reporting Unable to parse TLS packet header error.

Hell, there is no problem switching to the official environment. Could it be the pot in the background? [Don't worry about it, throw the pot out first! 】

With a flash of inspiration, SSL is caused by HTTPS, and asked whether the new background environment is HTTP or HTTPS. The result is http.

Sure enough, change https to http, run - success!
