Jsoup androidでSSLv3を無効にする方法は？ （javax.net.ssl.SSLHandshakeException）

Question

アンドロイド4.2.2でJsoupからprozis.comのWebサイトに接続しようとしたときにこのエラーが発生しましたが、サイトではTLS 1.2しか受け付けていないため失敗しています。 私はいくつかの読書をしたし、このバージョンのアンドロイドでSSLv3プロトコルがデフォルトで有効になっていないことが問題だとわかりました。 しかし私はJsoupを使用しているので、メインクラスを拡張してカスタムSSLSocketFactoryクラスを使用することはできません。 アンドロイド4でSSLv3を無効にする、またはTLS1.xを強制する他の方法はありますか？

String url; 
@Override 
protected Document doInBackground(String... params) { 
    this.url = params[0]; 
    Document resultDocument = null; 
    try { 
     resultDocument = Jsoup 
       .connect(url) 
       .validateTLSCertificates(false) 
       .userAgent(userAgent) 
       .timeout(NET_TIMEOUT) 
       .maxBodySize(0) //sem limite de tamanho do doc recebido 
       .get(); 

    } catch (IOException e) { 
     e.printStackTrace(); 
    } 
    return resultDocument;

Answer 1

がNetCipherライブラリを使用して、この作品を作る方法を見つけました。別のハンス・クリストフ・シュタイナーによって答え質問から 回答：build.gradle（アプリモジュール）ファイルでhttps://stackoverflow.com/a/32466614/6723008

がNetCipher依存関係をコンパイル含まれ、最新バージョンは1.2です：

compile 'info.guardianproject.netcipher:netcipher:1.2' 

（または、あなたがダウンロードすることができますnetcipher-1.2.jar、アプリ内で直接それを含める）

使用法：。

HttpsURLConnection netCipherconnection = NetCipher.getHttpsURLConnection(url); 
netCipherconnection.connect(); 

BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(netCipherconnection.getInputStream())); 
StringBuilder stringBuilder = new StringBuilder(); 
String stringHTML; 
while ((stringHTML = bufferedReader.readLine()) != null) 
    stringBuilder.append(stringHTML); 
bufferedReader.close(); 
Document resultDocument = Jsoup.parse(String.valueOf(stringBuilder)); 

Answer 2

もこの仕事をしてみてください 最初

key word : Jsoup SSl SSLHandshakeException

import java.security.KeyManagementException; 
import java.security.NoSuchAlgorithmException; 
import java.security.SecureRandom; 
import java.security.cert.CertificateException; 
import java.security.cert.X509Certificate; 

import javax.net.ssl.HostnameVerifier; 
import javax.net.ssl.HttpsURLConnection; 
import javax.net.ssl.SSLContext; 
import javax.net.ssl.SSLSession; 
import javax.net.ssl.X509TrustManager; 

/** 
* Created by Javad on 2017-12-05 at 8:29 PM. 
*/ 
public class SSLHelper { 

    public static void enableSSLSocket() throws KeyManagementException, NoSuchAlgorithmException { 
    HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier() { 
     public boolean verify(String hostname, SSLSession session) { 
     return true; 
     } 
    }); 

    SSLContext context = SSLContext.getInstance("TLS"); 
    context.init(null, new X509TrustManager[]{new X509TrustManager() { 
     public void checkClientTrusted(X509Certificate[] chain, String authType) throws CertificateException { 
     } 

     public void checkServerTrusted(X509Certificate[] chain, String authType) throws CertificateException { 
     } 

     public X509Certificate[] getAcceptedIssuers() { 
     return new X509Certificate[0]; 
     } 
    }}, new SecureRandom()); 
    HttpsURLConnection.setDefaultSSLSocketFactory(context.getSocketFactory()); 
    } 
} 

でSSLHelperを行い、その後、このようなあなたのサーバーにconncet：

private void connectToServer() { 
    new Thread(new Runnable() { 
    @Override 
    public void run() { 
     try { 
     SSLHelper.enableSSLSocket(); 
     Connection.Response response = Jsoup 
      .connect("https://URL") 
      .method(Connection.Method.POST) 
      .data("KEY", "VALUE") 
      .validateTLSCertificates(true) 
      .followRedirects(true) 
      .execute(); 
     Log.i("response", response.toString()); 
     Log.i("response", response.headers().toString()); 
     Log.i("response", response.body()); 

     Document doc = response.parse(); 
     String result = doc.body().text(); 

     } catch (IOException e) { 
     e.printStackTrace(); 
     G.toast("ERROR !"); 
     } catch (java.security.NoSuchAlgorithmException | java.security.KeyManagementException e) { 
     e.printStackTrace(); 
     } 
    } 
    }).start(); 
}
