SSL握手已中止：ssl = 0xb9e21100：SSL库失败，通常是协议错误

Question

我已经审查了许多与我的应用程序中发生的异常相同的问题。我只有在Kitkat运行旧版本的Retrofit / Okhttp来支持旧版本时才遇到此问题，这是在连接到HTTPS / SSL安全的网站时发生的。

Build.gradle

implementation('com.squareup.retrofit2:converter-gson:2.0.2') {
    exclude group: 'org.apache.commons', module: 'commons-io'
}
implementation('com.squareup.retrofit2:retrofit-converters:2.0.2') {
    exclude group: 'org.apache.commons', module: 'commons-io'
}
implementation 'com.squareup.okhttp3:logging-interceptor:3.12.1'
implementation 'com.squareup.okhttp3:okhttp:3.12.1'

错误：

javax.net.ssl.SSLHandshakeException: javax.net.ssl.SSLProtocolException: SSL handshake aborted: ssl=0xb9e21100: Failure in SSL library, usually a protocol error

05-09 18：53：43.132 12230-12230 / myapplication W / System.err：错误：14077410：SSL例程：SSL23_GET_SERVER_HELLO：sslv3警报握手失败（外部/openssl/ssl/s23_clnt.c:741 0x8d978990：0x00000000 ）

AndroidManifest：

android:usesCleartextTraffic="true"

这就是我如何获取客户的信息：

public static OkHttpClient getHttpClientBuilder(){
    ConnectionSpec spec = new ConnectionSpec.Builder(ConnectionSpec.COMPATIBLE_TLS)
            .supportsTlsExtensions(true)
            .tlsVersions(TlsVersion.TLS_1_2, TlsVersion.TLS_1_1, TlsVersion.TLS_1_0)

            .build();

            .connectTimeout(60, TimeUnit.SECONDS);

    return enableTls12OnPreLollipop(client).build();
}

enableTls12OnPreLollipop

    if (Build.VERSION.SDK_INT >= 16 && Build.VERSION.SDK_INT < 22) {

            SSLContext sc = SSLContext.getInstance("TLSv1.2");
            sc.init(null, null, null);
            client.sslSocketFactory(new Tls12SocketFactory(sc.getSocketFactory()));

            ConnectionSpec cs = new ConnectionSpec.Builder(ConnectionSpec.MODERN_TLS)
                    .tlsVersions(TlsVersion.TLS_1_2).build();

            List<ConnectionSpec> specs = new ArrayList<>();
            specs.add(cs);
            specs.add(ConnectionSpec.COMPATIBLE_TLS);
            specs.add(ConnectionSpec.CLEARTEXT);

            client.connectionSpecs(specs);
        } catch (Exception exc) {

        }
    }

    return client;
