根据url获取网页代码 个别字乱码问题

Question

URL myUrl = new URL(url);
HttpURLConnection urlConn = (HttpURLConnection)myUrl.openConnection();
InputStream in = urlConn.getInputStream();
int n = 0;
while ((n = in.read(b)) != -1) {
html += new String(b, 0, n);
}
html=new String(html.getBytes(),"utf-8");
html=new String(html.getBytes(),"gb2312");转换后会出现个别字的乱码！该如何解决！如果网站的编码是gb2312 转过来则是正常的,UTF-8转过来就会个别字乱码

Answer 1

public static String getContent(String urlStr) {
        return getContent(urlStr, "GBK");
    }    public static String getContent(String urlStr, String encode) {
        BufferedReader reader = null;
        InputStream is = null;
        try {
            URL url = new URL(urlStr);
            URLConnection conn = url.openConnection();
            conn.setConnectTimeout(5000);
            conn.connect();
            is = conn.getInputStream();
            reader = new BufferedReader(new InputStreamReader(is, encode));
            StringBuffer buffer = new StringBuffer();
            String line = null;
            while ((line = reader.readLine()) != null) {
                buffer.append(line);
            }
            return buffer.toString();
        } catch (IOException e) {
            return null;
        } finally {
            try {
                if (reader != null)
                    reader.close();
            } catch (IOException e) {
            }
            try {
                if (is != null)
                    is.close();
            } catch (IOException e) {
            }
        }
    }
用这种方法试下
