无法在java中使用silvertunnel netlib连接到tor网络

Question

我正在尝试连接到 tor 网络以发送匿名 HTTP 请求。但它会抛出IllegalBlockSizeException。我用过silvertunnel.org_netlib.jar

public static void main(String[] args) {
        try {
            // TODO code application logic here
             NetLayer lowerNetLayer = NetFactory.getInstance().getNetLayerById(NetLayerIDs.TOR); 

            lowerNetLayer.waitUntilReady();
            NetlibURLStreamHandlerFactory factory = new NetlibURLStreamHandlerFactory(false);
             factory.setNetLayerForHttpHttpsFtp(lowerNetLayer);
            String urlStr = "http://www.whatismyip.com/";
            URLStreamHandler handler = factory.createURLStreamHandler("http");
            URL context = null;
            URL url = new URL(context, urlStr, handler);
            HttpURLConnection connection = (HttpURLConnection) url.openConnection();
        connection.setDoOutput(true);
        connection.setRequestMethod("GET");
        //connection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
        //connection.setRequestProperty("Content-Length",  String.valueOf(postData.length()));

        // Write data
         OutputStream os = connection.getOutputStream();


        // Read response
        StringBuilder responseSB = new StringBuilder();
         BufferedReader br = new BufferedReader(new InputStreamReader(connection.getInputStream()));

        String line;
        while ( (line = br.readLine()) != null)
           responseSB.append(line);

        // Close streams
        br.close();
        os.close();
        Document doc=Jsoup.parse(responseSB.toString());

        } catch (IOException ex) {
            System.out.println(ex);
        }

    }

我收到了这个错误：

Answer 1

System.setProperty('socksProxyHost','127.0.0.1');

System.setProperty('socksProxyPort','9051');

在 main 方法中添加这两行并使用 vidalia for tor
