android - DefaultHttpClient、HttpPost 等已弃用。现在怎么发帖？

Question

在 Android API 22 之前，我只是做了以下事情:

/**
 * 
 * @param url
 * @param params
 * @return
 * @throws ClientProtocolException
 * @throws IOException
 */
public InputStream getStreamFromConnection(String url, List<NameValuePair> params) throws ClientProtocolException, IOException {
    if(ConnectionDetector.isConnectedToInternet(this.context)) {
        DefaultHttpClient httpClient = new DefaultHttpClient();
        HttpPost httpPost = new HttpPost(url);
        httpPost.setEntity(new UrlEncodedFormEntity(params, "utf-8"));

        HttpResponse httpResponse = httpClient.execute(httpPost);
        HttpEntity httpEntity = httpResponse.getEntity();

        return httpEntity.getContent();
    } else {
        return null;
    }
}

上面代码中的几乎所有内容现在都已弃用(NameValuePair、DefaultHttpClient、HttpPost、UrlEncodedFormEntity、HttpResponse、HttpEntity、ClientProtocolException)，我无法在 API 22+ 中找到推荐的方法。我现在应该如何发帖？

您现在可以使用 HttpURLConnection，您可以在下面的链接中找到完整的说明:
