android - 如何修复由对等 android 关闭的 javax.net.ssl.sslexception 连接

Question

我正在尝试使用“Volley”库从“电影数据库”获取 Json 数据，但它显示类似“javax.net.ssl.sslexception 连接被对等方关闭”的错误，所以请帮助解决这个问题。 ..

public class MainActivity extends AppCompatActivity {

    private TextView textView;
    String uri = "https://api.themoviedb.org/3/movie/popular?api_key=<MY_API_KEY>";
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        textView = (TextView)findViewById(R.id.titleid);
        loadtext();
    }

    private void loadtext() {
        JsonObjectRequest jsonObjectRequest = new JsonObjectRequest
                (Request.Method.GET, uri, null, new Response.Listener<JSONObject>() {

                    @Override
                    public void onResponse(JSONObject response) {
                        try {
                            JSONArray resultArray = response.getJSONArray("results");
                            JSONObject obj = resultArray.getJSONObject(1);
                            String name = obj.getString("title");
                            textView.setText(name);
                        } catch (JSONException e) {
                            e.printStackTrace();
                        }
                    }
                }, new Response.ErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError error) {
                        textView.setText("Error" + error);
                        error.printStackTrace();
                    }
                });
         MySingleton.getInstance(MainActivity.this).addToRequestQueue(jsonObjectRequest);
    }
}

Answer 1

1. 创建一个新类“MySSLSocketFactory”并扩展SSLSocketFactory

2. 复制并粘贴这段代码:

   SSLSocketFactory sslSocketFactory;
   
   public MySSLSocketFactory(SSLSocketFactory sslSocketFactory) {
       super();
       this.sslSocketFactory = sslSocketFactory;
   }
   
   @Override
   public String[] getDefaultCipherSuites() {
       return sslSocketFactory.getDefaultCipherSuites();
   }
   
   @Override
   public String[] getSupportedCipherSuites() {
       return sslSocketFactory.getSupportedCipherSuites();
   }
   
   @Override
   public SSLSocket createSocket(Socket s, String host, int port, boolean autoClose) throws IOException {
       SSLSocket socket = (SSLSocket) sslSocketFactory.createSocket(s, host, port, autoClose);
       socket.setEnabledProtocols(new String[]{"TLSv1.2"});
       return socket;
   }
   
   @Override
   public Socket createSocket(String host, int port) throws IOException, UnknownHostException {
       SSLSocket socket = (SSLSocket) sslSocketFactory.createSocket(host, port);
       socket.setEnabledProtocols(new String[]{"TLSv1.2"});
       return socket;
   }
   
   @Override
   public Socket createSocket(String host, int port, InetAddress localHost, int localPort) throws IOException,
           UnknownHostException {
       SSLSocket socket = (SSLSocket) sslSocketFactory.createSocket(host, port, localHost, localPort);
       socket.setEnabledProtocols(new String[]{"TLSv1.2"});
       return socket;
   }
   
   @Override
   public Socket createSocket(InetAddress host, int port) throws IOException {
       SSLSocket socket = (SSLSocket) sslSocketFactory.createSocket(host, port);
       socket.setEnabledProtocols(new String[]{"TLSv1.2"});
       return socket;
   }
   
   @Override
   public Socket createSocket(InetAddress address, int port, InetAddress localAddress, int localPort)
           throws IOException {
       SSLSocket socket = (SSLSocket) sslSocketFactory.createSocket(address, port, localAddress, localPort);
       socket.setEnabledProtocols(new String[]{"TLSv1.2"});
       return socket;
   }
   

3. 在您的代码中的“private void loadtext() {”之后粘贴:

   if(Build.VERSION.SDK_INT <= Build.VERSION_CODES.M) {

        try {
            ProviderInstaller.installIfNeeded(context);
        } catch (GooglePlayServicesRepairableException e) {
            e.printStackTrace();
        } catch (GooglePlayServicesNotAvailableException e) {
            e.printStackTrace();
        }
        SSLContext sslContext = null;
        try {
            sslContext = SSLContext.getInstance("TLSv1.2");
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        }
        try {
            sslContext.init(null, null, null);
        } catch (KeyManagementException e) {
            e.printStackTrace();
        }
        SSLEngine engine = sslContext.createSSLEngine();
    }

经过深思熟虑，它非常适合我。
