给你一段通过http连接web的代码
HttpClient httpClient = new DefaultHttpClient();
// HttpContext localContent = new BasicHttpContext();
HttpGet httpGet = new HttpGet(GOOGLE_API_URL + city);

try {
// HttpResponse response = httpClient.execute(httpGet, localContent);
HttpResponse response = httpClient.execute(httpGet);
if (response.getStatusLine().getStatusCode() != HttpStatus.SC_OK) {
Log.e(TAG, "Failed. status code is not ok.");
httpGet.abort();
} else {
// Get weather information successful
// Reset charset for Chinese
HttpEntity httpEntity = response.getEntity();
String string = EntityUtils.toString(httpEntity, "utf-8").trim();
InputStream is = new ByteArrayInputStream(string.getBytes());
return parseWeather(is);
}

} catch (Exception e) {
Log.e(TAG, "Failed to get weather information.", e);
e.printStackTrace();
} finally {
// disconnect network
httpClient.getConnectionManager().shutdown();
}

            // CMWAP连接方式
            if (connection.Type == 1)
            {
                URL url = new URL(urlString);
