android http连接通常使用方式

URL url = new URL(path);

HttpURLConnection conn = null;

try {

conn = (HttpURLConnection) url.openConnection();

conn.setConnectTimeout(3000);

conn.setReadTimeout(3000);

} catch (IOException e) {

Log.e(TAG, "openConnection() failed! url = " + url);

e.printStackTrace();

return false;

}

try {

conn.setRequestMethod("GET");

if (conn.getResponseCode() == 200) {

InputStream xmlStream = conn.getInputStream();

parserStates(xmlStream);

} else {

Log.e(TAG,

"RequestMethod failed! code = "

+ conn.getResponseCode());

}

} catch (ConnectTimeoutException e) {

return false;

} catch (IOException e) {

e.printStackTrace();

return false;

}

if (conn != null) {

conn.disconnect();

}

在设置超时时间的方法中，设置超时的时间3000,在阻塞的getResponseCode方法中时间不准。

这样采取org.apache.http.client.HttpClient方法

HttpParams httpParameters = new BasicHttpParams();

HttpConnectionParams.setConnectionTimeout(httpParameters, 500);

HttpConnectionParams.setSoTimeout(httpParameters, 500);

HttpGet httpget = new HttpGet(updateUrl.toURI());

DefaultHttpClient httpClient = new DefaultHttpClient();

httpClient.setParams(httpParameters);

HttpResponse response = httpClient.execute(httpget);

HttpEntity entity = response.getEntity();

InputStream is = entity.getContent();

//download file..... 这种方法可以准备的计算阻塞时间
