通过接口获取网络资源--json与图片的工具类

public class NetUtil {
    //使用HttpClient网络请求json
    public static String getHttpClientJson(String urlString){
        DefaultHttpClient defaultHttpClient = new DefaultHttpClient();
        HttpGet httpGet = new HttpGet(urlString);
        try {
            HttpResponse response = defaultHttpClient.execute(httpGet);
            int statusCode = response.getStatusLine().getStatusCode();
            if (statusCode==200){
                HttpEntity entity = response.getEntity();
                String string = EntityUtils.toString(entity);
                Log.e("ck-json",string);
                return string;
            }else {
                Log.e("ck",statusCode+"");
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
        return "";
    }
    //网络请求json
    public static String getNetJson(String urlString){
        try {
            URL url = new URL(urlString);
            HttpURLConnection urlConnection= (HttpURLConnection) url.openConnection();
//            urlConnection.setConnectTimeout(8000);
            int responseCode = urlConnection.getResponseCode();
            if (responseCode==200){
                InputStream inputStream = urlConnection.getInputStream();
                BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));
                StringBuffer stringBuffer = new StringBuffer();
                String len="";
                while ((len=reader.readLine())!=null) {
                    stringBuffer.append(len);
                }
                String string = stringBuffer.toString();
                Log.e("ck--result", string);
                return string;
            }
        } catch (MalformedURLException e) {
            e.printStackTrace();
            Log.e("ck", e.toString());
        } catch (IOException e) {
            e.printStackTrace();
            Log.e("ck", e.toString());
        }
        return "";
    }
    //网络请求图片
    public static Bitmap getNetBitmap(String urlBitmap) {
        try {
            URL url = new URL(urlBitmap);
            HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
//            urlConnection.setConnectTimeout(8000);
            int responseCode = urlConnection.getResponseCode();
            if (responseCode==200){
                InputStream inputStream = urlConnection.getInputStream();
                Bitmap bitmap = BitmapFactory.decodeStream(inputStream);
                return bitmap;
            }else {
                //do nothing
                Log.e("ck","请求图片状态码"+responseCode);
            }
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    }
}

需要权限：

HttpClient需要modle的buil.gradle文件中android根标签下   添加useLibrary 'org.apache.http.legacy'
