Question

我正在使用Jsoup使用代理发出GET请求。以下是代码

代码1

    // Proxy
    Connection connection = Jsoup.connect(url).proxy("127.0.0.1", 8888);

    connection.userAgent(Constants.USER_AGENT);
    connection.timeout(Constants.TIME_OUT);

    connection.get();

代码2

    URL url = new URL(myUrl);
    Proxy proxy = new Proxy(Proxy.Type.HTTP, new InetSocketAddress("127.0.0.1", 8889)); // or whatever your proxy is
    HttpURLConnection uc = (HttpURLConnection)url.openConnection(proxy);

    uc.connect();

      String line = null;
      StringBuffer tmp = new StringBuffer();
      BufferedReader in = new BufferedReader(new InputStreamReader(uc.getInputStream()));
      while ((line = in.readLine()) != null) {
        tmp.append(line);
      }

      Document doc = Jsoup.parse(String.valueOf(tmp));

但两者都在抛出异常。我也尝试使用不同的端口，如8898等，但每次抛出异常，这意味着端口没有问题。

如果我尝试在没有代理的情况下发出请求，它可以正常工作。有什么问题？

PS：我正在使用Jsoup v1.9.1
