java - 输入流特殊字符UTF-8

Question

为什么这个输入流没有返回正确的字符？即使使用 UTF-8 读取后，Código 也会变成 C�digo

HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setReadTimeout(10000 /* milliseconds */);
        conn.setConnectTimeout(15000 /* milliseconds */);
        conn.setRequestMethod("GET");
        conn.setDoInput(true);
        conn.setRequestProperty("Accept-Charset", "UTF-8");

        // Starts the query
        conn.connect();
        InputStream stream = conn.getInputStream();

        byte[] buffer = new byte[1024];
        int bytesRead = stream.read(buffer);
        String page = new String(buffer, 0, bytesRead, "UTF-8");



        //Page is returning, C�digo instead of Código

Answer 1

试试这个，

BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream(), StandardCharsets.UTF_8));
