public Bitmap getWebBitmap(String imgUrl) {
        Bitmap bitmap =null;
        try {
            InputStream inputStream = null;
            URL url;
            url = new URL(imgUrl);
            if (url != null) {
                // 打开连接
                HttpURLConnection httpURLConnection = (HttpURLConnection) url
                        .openConnection();
                httpURLConnection.setConnectTimeout(3000);// 设置网络连接超时的时间为3秒
                httpURLConnection.setDoInput(true); // 打开输入流
                int responseCode = httpURLConnection.getResponseCode(); // 获取服务器响应值
                if (responseCode == HttpURLConnection.HTTP_OK) { // 正常连接
                    inputStream = httpURLConnection.getInputStream(); // 获取输入流
                }
                bitmap = BitmapFactory.decodeStream(inputStream);
            }
        } catch (Exception e) {
            e.printStackTrace();
