java 简单的HttpClient工具类，解决返回中文有部分乱码的情况

 import java.io.IOException;
 import java.io.InputStream;

 import org.apache.http.HttpEntity;
 import org.apache.http.HttpResponse;
 import org.apache.http.client.ClientProtocolException;
 import org.apache.http.client.HttpClient;
 import org.apache.http.client.methods.HttpGet;
 import org.apache.http.impl.client.DefaultHttpClient;

 public class HttpClientUtil {
     public static String sendGet(String url,String data) throws ClientProtocolException, IOException
     {
         // 创建HttpClient实例
         HttpClient httpclient = new DefaultHttpClient();
         // 创建Get方法实例
         HttpGet httpgets = new HttpGet(url+data);
         HttpResponse response = httpclient.execute(httpgets);
         HttpEntity entity = response.getEntity();
         if (entity != null) {
             InputStream instreams = entity.getContent();
             String str = convertStreamToString(instreams);
             httpgets.abort();
             return str;
         }
         return null;
     }

     public static String convertStreamToString(InputStream is) {
         StringBuilder sb1 = new StringBuilder();
         byte[] bytes = new byte[4096];
         int size = 0;

         try {
             while ((size = is.read(bytes)) > 0) {
                 String str = new String(bytes, 0, size, "UTF-8");
                 sb1.append(str);
             }
         } catch (IOException e) {
             e.printStackTrace();
         } finally {
             try {
                 is.close();
             } catch (IOException e) {
                e.printStackTrace();
             }
         }
         return sb1.toString();
     }
 }

是完整代码。
