java - Android HttpPost javax.net.ssl.SSLProtocolException 无法识别的名称

Question

我正尝试从 Android 平板电脑向 api 发布一些数据，但我不断收到 SSLProtocolException，我无法找出问题所在。

这是我不断收到的错误:

javax.net.ssl.SSLHandshakeException: javax.net.ssl.SSLProtocolException: SSL handshake aborted: ssl=0x7bccbdc8: Failure in SSL library, usually a protocol error

这是我正在使用的代码。

public  class sendJSONdata extends AsyncTask<String, String, String>{

    String httpAuthUser=*username*;
    String httpAuthPassword=*password*;


    String Bedrijf;
    String Naam;
    String Functie;
    String Vestiging;
    String Telefoonnummer;
    String Email;
    String Opmerkingen;
    String GesprokenMet;
    Context context;


    @Override
    protected void onPreExecute() {
        super.onPreExecute();
    }


    public sendJSONdata(String[] values,Context context)
    {
         Bedrijf= values[0];
         Naam= values[1];
         Functie= values[2];
         Vestiging= values[3];
         Telefoonnummer= values[4];
         Email= values[5];
         Opmerkingen= values[6];
         GesprokenMet= values[7];
        this.context=context;
        //System.setProperty("jsse.enableSNIExtension", "false");

    }

    protected String doInBackground(String... strings) {
        ///Build JSON object and fill with your data
        JSONObject subpostMessage = new JSONObject();
        try {
            subpostMessage.put("emailAdres", Email);
            subpostMessage.put("Naam", Naam);
            subpostMessage.put("Bedrijfsnaam", Bedrijf);
            subpostMessage.put("Telnummer", Telefoonnummer);
            subpostMessage.put("Functie", Functie);
            subpostMessage.put("Vestiging", Vestiging);
            subpostMessage.put("Opmerkingen", Opmerkingen);
            subpostMessage.put("GesprokenMet", GesprokenMet);
        } catch (JSONException e) {
            e.printStackTrace();
        }

        //Connect to HttpClient with basic Aut
        HttpParams httpParameters = new BasicHttpParams();
        HttpClient httpclient = new MyHttpClient(httpParameters,context);//new DefaultHttpClient(httpParameters);//
        HttpPost httppost = new HttpPost(*Https to php file");
        String base64EncodedCredentials = "Basic " + Base64.encodeToString((httpAuthUser + ":" + httpAuthPassword).getBytes(), Base64.NO_WRAP);
        httppost.setHeader("Authorization", base64EncodedCredentials);

        String responseStr = null;
        try {
            // Add your data to te connection
            List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);
            nameValuePairs.add(new BasicNameValuePair("postData", subpostMessage.toString()));
            httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

            Log.d("httpPost: ",httppost.getMethod());
            Log.d("ValuePairs- name: ",nameValuePairs.get(0).getName()+ " val: "+ nameValuePairs.get(0).getValue());

            // Execute HTTP Post Request
            HttpResponse response = httpclient.execute(httppost);

            //Recover result response
            responseStr = EntityUtils.toString(response.getEntity());

            Log.d("JSON ATTEMPT","Response: "+responseStr);
        } catch (ClientProtocolException e) {
            Log.d("JSON ATTEMPT","Response:CPerror "+e.toString());
        } catch (IOException e) {
            Log.d("JSON ATTEMPT","Response:IOerror "+e.toString());
        }
        return responseStr;
    }


    protected void onPostExecute(String result) {
        if (result == null) {
            //Request Failed
            return;
        }

        //System.out.println("RECEIVED RESPONSE: " + result);

        try {
            JSONObject jObj = new JSONObject(result);
        } catch (JSONException e) {
            e.printStackTrace();
        }
    }

    @Override
    protected void onProgressUpdate(String... values) {
    }

}

还有它被调用的地方。

    void postJSONdata()
    {
        String[] values  = new String[8];
        values[0]=bnaam.getText().toString();
        values[1]=naam.getText().toString();
        values[2]=functie.getText().toString();
        values[3]=vestiging.getText().toString();
        values[4]=tele.getText().toString();
        values[5]=mail.getText().toString();
        values[6]=opmerking.getText().toString();
        values[7]=gesprokenmet.getText().toString();
        sendJSONdata task = new sendJSONdata(values,getApplicationContext());
        task.execute();
    }

这个错误在我尝试的任何 jdk 上抛出 (6,7,8)，我发现的大多数帖子都表明它与 7 中引入的 SNI 有关，但对于 6 我仍然有同样的错误。

Answer 1

此问题是由服务器的配置以及客户端不支持或无效支持 SNI 引起的。如果没有使用 SNI 或者使用了错误的名称，服务器将返回 unrecognized_name 警报。因此，您需要确保使用支持 SNI 的 Java 版本，启用它并使用正确的名称访问服务器。
