Android 7.0 : 'javax.net.ssl.SSLHandshakeException: 连接被对端关闭

Question

当我尝试从我的应用程序访问 'https' 网络服务时，出现“javax.net.ssl.SSLHandshakeException：连接被对等方关闭”错误.相同的 Web 服务在 Chrome 浏览器中运行良好。

此问题仅在 Android 7.0 上发生，在 Android 6.0 和 5.0 中运行良好。

服务器是 CA 认证的，不是自签名的。

尝试使用此代码，它对我有用:

 private static void initializeSSLContext(Context mContext){
    try {
        SSLContext.getInstance("TLSv1.2");
    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    }
    try {
        ProviderInstaller.installIfNeeded(mContext.getApplicationContext());
    } catch (GooglePlayServicesRepairableException e) {
        e.printStackTrace();
    } catch (GooglePlayServicesNotAvailableException e) {
        e.printStackTrace();
    }
}

不要忘记使用 google 安全库 :

  compile 'com.google.android.gms:play-services-safetynet:11.6.2'

我不得不使用扩展的 SSLSocket class 来包含所有协议和密码套件以解决这个问题。解决方案在于 GetProtocolList() & GetCipherList()

private static OkHttpClient.Builder enableAllProtocols(OkHttpClient.Builder client) {
    try {
        client.sslSocketFactory(new SSLSocketFactoryExtended(), provideX509TrustManager());
    } catch (Exception exc) {
        Log.e("OkHttpTLSCompat", "Error while setting Protocols", exc);
    }
    return client;
}

SSLSocketFactoryExtended Class 文件

    private SSLContext mSSLContext;
    private String[] mCiphers;
    private String[] mProtocols;

    public SSLSocketFactoryExtended() throws NoSuchAlgorithmException, KeyManagementException {
        initSSLSocketFactoryEx(null,null,null);

    public Socket createSocket(Socket s, String host, int port, boolean autoClose) throws IOException {
