apache post 连接网络 读取返回数据
下面是post的：public class Test extends Activity implements OnClickListener {
public Context context;
private TextView textView1;

// URI uri = new URI(URL);
// HttpPost post = new HttpPost();
// post.setURI(uri);
// Post运作传送变数必须用NameValuePair[]阵列储存
List<NameValuePair> params = new ArrayList<NameValuePair>();
params.add(new BasicNameValuePair("name", "this is post"));
// params.add(new BasicNameValuePair("version", getVersionCode(context) + ""));
// params.add(new BasicNameValuePair("os", "android"));
// params.add(new BasicNameValuePair("flag", "10"));
// params.add(new BasicNameValuePair("modle", getModelNumber()));
// params.add(new BasicNameValuePair("channel", "samsung"));
try {
// 发出HTTP request，把字符集设置在request里面
post.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));
//相当于打开链接，给出回应
HttpResponse httpResponse = httpClient.execute(post);
int httpCode = httpResponse.getStatusLine().getStatusCode();
//HTTP_OK=200，服务器作出反映，找到了服务器，并且回应了。
if (httpCode == HttpURLConnection.HTTP_OK) {
// //取出回应字串
// String strResult=EntityUtils.toString(httpResponse.getEntity());
// textView1.setText(strResult);
//这里可以做很多事
