如何在不打開網頁的情況下讓應用自動登錄？

Question

我打算製作一個應用程序，讓用戶無需打開瀏覽器即可訪問互聯網，只需點擊一下鼠標鍵入登錄信息即可獲得權限。我不知道如何讓應用程序打開網頁並在不使用瀏覽器的情況下填充信息。任何人都可以給我一些建議嗎？

訪問網站的登錄頁面並檢查登錄表單。然後使用DefaultHttpClient發送登錄請求。

這大約是我如何使用它：

public Boolean login() throws Exception { 

    DefaultHttpClient httpClient = new DefaultHttpClient(); 

    // add login data (edit this to fit your website) 
    List<NameValuePair> nvps = new ArrayList<NameValuePair>(); 
    nvps.add(new BasicNameValuePair("NAME_OF_USERNAME_FIELD", USERNAME)); 
    nvps.add(new BasicNameValuePair("NAME_OF_PASSWORD_FIELD", PASSWORD)); 

    // create the request 
    HttpPost httpost = new HttpPost(LOGIN_URL); 
    httpost.setEntity(new UrlEncodedFormEntity(nvps, DEFAULT_ENCODING)); 

    // execute the form 
    HttpResponse response = httpClient.execute(httpost); 
    BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity() 
      .getContent(), DEFAULT_ENCODING)); 

    // fetch the result of the http request and save it as a string 
    String line; 
    StringBuilder sb = new StringBuilder(); 
    while ((line = reader.readLine()) != null) { 
     sb.append(line).append("\n"); 
    } 
    String input = sb.toString(); 

    // check if the login worked. This depends on the response of your website 
    Pattern pattern = Pattern.compile(LOGIN_WORKED_PATTERN); 
    Matcher m = pattern.matcher(input); 

    if (m.find()) 
     return true; 

    return false; 
}
