Android的HTTP身份验证

Question

I have a problem with a http authentication. No problem to connect with other web-service without authentication. But I don't know how i can connect to this http authentication with android. So in my app, i have two textfield (login and password). And a button to connect to an address and get informations about the user (json data). In a first time, i would like to pass identifiers in adress : https://proxyepn-test.epnbn.net/wsapi/user . Like https://login:password@proxyepn-test.epnbn.net/wsapi/user . And display data ine the log. Can you help me ?

` I try this.

public HashMap<String, String> btn_connexion(View view) {
    etPseudo = (EditText) findViewById(R.id.editText);
    etMdp = (EditText) findViewById(R.id.editText2);
    final String pseudo = etPseudo.getText().toString();
    final String mdp = etMdp.getText().toString();


    //String urldisplay = "https://" + pseudo + ":" + mdp + "@proxyepn-test.epnbn.net/wsapi/user";

    @Override
    public Map<String, String> getHeaders() throws AuthFailureErro {
        HashMap<String, String> params = new HashMap<>();
        String creds = String.format("%s:%s", pseudo, mdp);
        String auth = "Basic " + Base64.encodeToString(creds.getBytes(), Base64.NO_WRAP);
        params.put("Authorization", auth);
        return params;


    }



}`

//class to establish the connection

public static class RestOperation extends AsyncTask<String, Void, String> {

    String content;
    String error;
    String data = "";


    @Override
    protected String doInBackground(String... params) {
        BufferedReader br = null;

        URL url;
        try {
            url = new URL(params[0]);

            URLConnection connection = url.openConnection();
            connection.setDoOutput(true);

            OutputStreamWriter outputStreamWr = new OutputStreamWriter(connection.getOutputStream());
            outputStreamWr.write(data);
            outputStreamWr.flush();

            br = new BufferedReader(new InputStreamReader(connection.getInputStream()));
            StringBuilder sb = new StringBuilder();
            String line = null;

            while((line = br.readLine())!=null) {
                sb.append(line);
                sb.append(System.getProperty("line.separator"));
            }

            content = sb.toString();
            Log.i("content",content);

        } catch (MalformedURLException e) {
            error = e.getMessage();
            e.printStackTrace();
        } catch (IOException e) {
            error = e.getMessage();
            e.printStackTrace();
        } finally {
            try {
                if(br != null) {
                    br.close();
                }
            } catch (IOException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
        return content;

Encode your username and password to base64 string and pass to header of your request in Authorization key.

You can use volley library and pass username and password in header as:

        @Override
        public Map<String, String> getHeaders() throws AuthFailureError {
            HashMap<String, String> params = new HashMap<>();
            String creds = String.format("%s:%s", "your-username", "your-password");
            String auth = "Basic " + Base64.encodeToString(creds.getBytes(), Base64.NO_WRAP);
            params.put("Authorization", auth);
            return params;
        }

If you are using HttpUrlConnection then pass basic auth in header as:

        String creds = String.format("%s:%s", "your-username", "your-password");
        String auth = "Basic " + Base64.encodeToString(creds.getBytes(), Base64.NO_WRAP);
        yourHttpUrlConnection.setRequestProperty("Authorization", auth);
