我有适用于大多数设备的 Android 应用程序 最近一些黑客试图对我们的服务器进行 DDOS 攻击，迫使我们添加一些安全性和一些防火墙

不是某些设备不工作，给我以下异常

javax.net.ssl.SSLException: SSL handshake aborted: ssl=0x63eb8240: I/O error during system call, Connection reset by peer 

谁能告诉我现在是什么问题，我该如何解决？

这是我的执行方法的代码

public static BaseResponse execute(Context context, BaseRequest request) {

    mStartTime = System.nanoTime();

    BaseResponse response = new BaseResponse();
    DataOutputStream outputStream;
    try {
        URL url = new URL(request.getURL());
        HttpsURLConnection urlConnection = (HttpsURLConnection) url.openConnection();
        urlConnection.setConnectTimeout(TIMEOUT_DURATION);
        urlConnection.setReadTimeout(TIMEOUT_DURATION);
        urlConnection.setRequestMethod(request.getRequestType().getValue());
        urlConnection.addRequestProperty("Accept", "application/json");
        urlConnection.addRequestProperty("Content-Type","application/json");
        urlConnection.setRequestProperty("Accept-Charset", CHARACTER_SET);
        urlConnection.addRequestProperty("Device-Id", PhoneUtils.getDeviceId(context));
        urlConnection.addRequestProperty("Version-Number", PhoneUtils.getAppVersion(context));


        TLSSocketFactory socketFactory = new TLSSocketFactory();
        urlConnection.setSSLSocketFactory(socketFactory);

        switch (request.getRequestType()) {
            case POST:
            case PUT:
                urlConnection.setDoOutput(true);
                if (request.getStringEntity() != null) {
                    outputStream = new DataOutputStream(urlConnection.getOutputStream());
                    BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(outputStream, CHARACTER_SET));
                    writer.write(request.getStringParam());
                    writer.close();
                    outputStream.flush();
                    outputStream.close();
                }

                break;
            case GET:
                urlConnection.setDoOutput(false);
                break;
        }

        urlConnection.connect();

        try {
            if (urlConnection.getResponseCode() == STATUS_OK) {
                InputStream inputStream = new BufferedInputStream(urlConnection.getInputStream());
                BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
                StringBuilder result = new StringBuilder();
                String line;
                while ((line = reader.readLine()) != null) {
                    result.append(line);
                }

                inputStream.close();
                response.setResponse(convertStringToJSONObject(result.toString()));
            } else {
                response.setResponse(null);
            }
        } catch (Exception ex) {
            response.setAppError(AppError.DATA_ERROR);
        }
    } catch (MalformedURLException e) {
        e.printStackTrace();
        response.setAppError(AppError.PARSING_ERROR);
    } catch (IOException e) {
        e.printStackTrace();
        response.setAppError(AppError.DATA_ERROR);
    } catch (Exception e) {
        e.printStackTrace();
        response.setAppError(AppError.DATA_ERROR);
    }

    return response;
}

最佳答案

在进行任何网络调用之前在您的代码中使用它

/**
 * Initialize SSL
 * @param mContext
 */
public 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();
    }
}

我遇到了同样的问题，这段代码解决了我的问题。仅供引用:我正在使用改造库进行网络调用

您需要在 build.gradle

implementation 'com.google.android.gms:play-services-safetynet:17.0.0
