java 简单的HttpClient工具类，解决返回中文有部分乱码的情况。

1. import java.io.IOException;
2. import java.io.InputStream;
4. import org.apache.http.HttpEntity;
5. import org.apache.http.HttpResponse;
6. import org.apache.http.client.ClientProtocolException;
7. import org.apache.http.client.HttpClient;
8. import org.apache.http.client.methods.HttpGet;
9. import org.apache.http.impl.client.DefaultHttpClient;
11. public class HttpClientUtil {
12.     public static String sendGet(String url,String data) throws ClientProtocolException, IOException
13.     {
14.         // 创建HttpClient实例
15.         HttpClient httpclient = new DefaultHttpClient();
16.         // 创建Get方法实例
17.         HttpGet httpgets = new HttpGet(url+data);
18.         HttpResponse response = httpclient.execute(httpgets);
19.         HttpEntity entity = response.getEntity();
20.         if (entity != null) {
21.             InputStream instreams = entity.getContent();
22.             String str = convertStreamToString(instreams);
23.             httpgets.abort();
24.             return str;
25.         }

30.         StringBuilder sb1 = new StringBuilder();
31.         byte[] bytes = new byte[4096];
32.         int size = 0;
34.         try {

36.                 String str = new String(bytes, 0, size, “UTF-8″);
37.                 sb1.append(str);
38.             }

        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。
