I want to get all page content from a url,but I cant make it,someone helps me.

This is my code:

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;
}

}

In Logcat,it writes:

I can't understand,why it output many times.

By the way,my test Url is "http://www.google.com"

有帮助吗？

解决方案

Logcat does a couple of things without your request:

  1. If you give it a long string, it automatically breaks it into multiple logcat output messages.
  2. If you give it a really long string, it truncates it after some number of characters. I don't know the exact number, but it seems it is more than 4000.

For example, you can check out these:

其他提示

Try this code,

 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);

Hope this helps
