如何在Android中使用身份驗證連接到Web服務JSON？

Question

我有這個大問題。我有這個網址我的JSON http://phsjulchsvr4.therock.com.ph:1217/api/users和我要去使用此代碼來分析它：

public class JSONParser { 

static InputStream is = null; 
static JSONObject jObj = null; 
static String json = ""; 

// constructor 
public JSONParser() { 

} 

public JSONObject getJSONFromUrl(String url) { 

    // Making HTTP request 
    try { 
     // defaultHttpClient 
     DefaultHttpClient httpClient = new DefaultHttpClient(); 
     HttpGet httpGet = new HttpGet(url); 

     HttpResponse httpResponse = httpClient.execute(httpGet); 
     HttpEntity httpEntity = httpResponse.getEntity(); 
     is = httpEntity.getContent();   

    } catch (UnsupportedEncodingException e) { 
     e.printStackTrace(); 
    } catch (ClientProtocolException e) { 
     e.printStackTrace(); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 

    try { 
     BufferedReader reader = new BufferedReader(new InputStreamReader(
       is, "iso-8859-1"), 8); 
     StringBuilder sb = new StringBuilder(); 
     String line = null; 
     while ((line = reader.readLine()) != null) { 
      sb.append(line + "\n"); 
     } 
     is.close(); 
     json = sb.toString(); 
    } catch (Exception e) { 
     Log.e("Buffer Error", "Error converting result " + e.toString()); 
    } 

    // try parse the string to a JSON object 
    try { 
     jObj = new JSONObject(json); 
    } catch (JSONException e) { 
     Log.e("JSON Parser", "Error parsing data " + e.toString()); 
    } 

    // return JSON String 
    return jObj; 

    } 
} 

問題是我無法連接到這個網址，因爲它有一個認證。我該怎麼做。使用我的JSONParser類來連接這個URL？ 獲取HttpResponse可以執行URL

這裏是你可能需要的東西：

public String getValueResult(String url) { 
    System.out.println(url); 

    String username = "admin"; 
    String password = "admin"; 

    String unp = username+":"+password; 

    try {   
     HttpClient httpclient = new DefaultHttpClient(); 
     // HttpPost httppost = new HttpPost(domain.trim()+"/qhms/wse_hmlogin.php?loginid="+user.trim()+"&logpass="+pass.trim()); 
     // HttpPost httppost = new HttpPost(domain+"/qhms/wse_hmlogin.php?loginid="+user+"&logpass="+pass); 
     // HttpPost httppost = new HttpPost("http://svv.in.net/service/index.php?user=Customer&pass=cus&des=rtr%20r%20rtr%20trtrt"); 
     HttpPost httppost = new HttpPost(url); 
     // httppost.setHeader("Authorization","Basic "+"admin:admin"); 
     String encoded_login = Base64.encodeToString(unp.getBytes(), Base64.NO_WRAP); 
     httppost.setHeader(new BasicHeader("Authorization", "Basic "+encoded_login)); 

     System.out.println("URL="+httppost.toString()); 

     // HttpPost httppost = new HttpPost("http://quantumr.info/qrms/call_service/wse_getitem.php?compkey=astres1312"); 
     HttpResponse response = httpclient.execute(httppost); 
     HttpEntity entity = response.getEntity(); 
     is = entity.getContent(); 
    } catch (Exception e) { 
     Log.e("log_tag", "Error in http connection" + e.toString()); 
    } 
    // convert response to string 
    try { 
     BufferedReader reader = new BufferedReader(new InputStreamReader(is, "iso-8859-1"), 8); 
     sb = new StringBuilder(); 
     sb.append(reader.readLine() + "\n"); 

     String line = "0"; 
     while ((line = reader.readLine()) != null) { 
      sb.append(line + "\n"); 
     } 
     is.close(); 
     result = sb.toString(); 
    } catch (Exception e) { 
     Log.e("log_tag", "Error converting result " + e.toString()); 
    } 
    return result; 
}

嘗試做的請求時使用此：

try { 
     // defaultHttpClient 
     DefaultHttpClient httpClient = new DefaultHttpClient(); 
     HttpGet httpGet = new HttpGet(url); 

     // Set the username and password 
     String authStr = "username" + ":" + "password"; 

     // Encode authentication values, and add to header 
     String authStrEncoded = Base64.encode(authStr.getBytes("UTF-8")); 
     httpGet.addHeader("Authorization", "Basic " + authStrEncoded); 

     HttpResponse httpResponse = httpClient.execute(httpGet); 
     HttpEntity httpEntity = httpResponse.getEntity(); 
     is = httpEntity.getContent();   

    } catch (UnsupportedEncodingException e) { 
     e.printStackTrace(); 
    } catch (ClientProtocolException e) { 
     e.printStackTrace(); 
    } catch (IOException e) { 
     e.printStackTrace(); 
    }
