我在尝试通过 android 4.2.2 中的 Jsoup 连接到 prozis.com 网站时遇到此错误，但由于该站点仅接受 TLS 1.2 而失败。我做了一些阅读，我发现在这个版本的 android 中默认情况下没有启用 SSLv3 协议是一个问题。但是当我使用 Jsoup 时，我无法扩展主类并使用自定义 SSLSocketFactory 类。是否有其他方法可以在 android 4 中禁用 SSLv3 或强制 TLS1.x？

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;

了解如何使用NetCipher库完成这项工作。Hans-Christoph Steiner 回答的另一个问题的答案：https ://stackoverflow.com/a/32466614/6723008

在 build.gradle（app 模块）文件中包含 NetCipher 编译依赖，最新版本为 1.2：

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

（或者您可以下载 netcipher-1.2.jar 并将其直接包含在您的应用程序中。）

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));

尝试这项工作以及首先制作 SSLHelper

关键词：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());
  }
}

然后像这样连接到您的服务器：

    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();
}
