我無法從Android API中的網址獲取所有內容16

我想從網址獲取所有網頁內容，但我無法做到，有人幫助我。我無法從Android API中的網址獲取所有內容16

這是我的代碼：

public class HttpHelper { 
private static final int CONNECTION_TIMEOUT = 30000; 
private static final int SOCKET_TIMEOUT = 10000; 

public static String GET(String uri) { 
    HttpParams params = new BasicHttpParams(); 
    HttpConnectionParams.setConnectionTimeout(params, CONNECTION_TIMEOUT); 
    HttpConnectionParams.setSoTimeout(params, SOCKET_TIMEOUT); 
    HttpClient httpclient = new DefaultHttpClient(params); 
    HttpResponse response; 
    String data = ""; 
    try { 
     response = httpclient.execute(new HttpGet(uri)); 
     StatusLine statusLine = response.getStatusLine(); 

     if (statusLine.getStatusCode() == HttpStatus.SC_OK) { 
      ByteArrayOutputStream out = new ByteArrayOutputStream(); 
      response.getEntity().writeTo(out); 
      out.close(); 
      data = out.toString(); 
      Log.i("html", data); 
     } else { 
      // Closes the connection. 
      response.getEntity().getContent().close(); 
      throw new IOException(statusLine.getReasonPhrase()); 
     } 
    } catch (ClientProtocolException e) { 
    } catch (IOException e) { 
    } 
    return data; 
}

}

在logcat中，它寫道：

我不明白，爲什麼很多輸出倍。

順便說一句，我的測試URL爲「http://www.google.com」

具體問題是什麼？你也忽略了你可能遇到的任何異常，至少記錄它們。 – laalto

我記錄了異常，它什麼也沒有記錄，也就是說，沒有出現異常。 – lhking

logcat的做了幾件事情沒有你的要求：

如果你給它一個很長的字符串，它會自動分解成多個logcat的輸出消息。
如果你給它一個真的長字符串，它會在一些字符後截斷它。我不知道確切的數字，但現在看來，這是超過4000

例如，你可以看看這些：

非常感謝，它適合我！ – lhking

很高興我能幫到你！你可以考慮接受這個答案作爲解決方案，以便其他人更清楚地知道你的問題已經解決。 –

試試這個代碼，

HttpResponse response = httpclient.execute(httpget); 
     in = new BufferedReader(new InputStreamReader(response.getEntity().getContent())); 
     StringBuffer sb = new StringBuffer(""); 
     String line = ""; 
     String NL = System.getProperty("line.separator"); 
     while ((line = in.readLine()) != null) {      
      sb.append(line + NL); 
     } 
     in.close(); 
     String data= sb.toString(); 
     Log.i("html", data);

Hop e這可以幫助

謝謝，我的類HttpHelper代碼是對的，Log.i（「html」，data）有一些問題 – lhking

是的，Log有一定的限制。它不會顯示特定限制後的數據。 – Swapnil
