试图在 apache tomcat 7 上设置谷歌玻璃快速启动项目。当我尝试启动它时它工作正常：http://localhost:8080当我在我的家庭网络时。但是当我在公司网络中时它不起作用。

在尝试交换访问令牌之前，我已经在 context.xml 和代码中设置了代理配置。我在源代码中的 AuthServlet 类中收到连接被拒绝异常。我已经修改了源代码以在这里定义代理设置的系统变量。

当我在设置代理后尝试连接到网络上的任何 url 时，我能够连接到互联网，但是令牌请求的交换失败，不知道为什么会这样。有人可以指出我正确的方向吗？

下面是显示代理设置的代码：

public class AuthServlet extends HttpServlet {
  private static final Logger LOG = Logger.getLogger(AuthServlet.class.getSimpleName());

  @Override
  protected void doGet(HttpServletRequest req, HttpServletResponse res) throws IOException {
      System.out.println("inside authservlet");
      System.setProperty("http.proxyHost", "proxy server");
      System.setProperty("http.proxyPort", "proxy server port");
      Authenticator.setDefault(
              new Authenticator() {
                  public PasswordAuthentication getPasswordAuthentication() {
                      return new PasswordAuthentication(
                              "username", "password".toCharArray());
                  }
              }
              );
      System.setProperty("http.proxyUser", "username");
      System.setProperty("http.proxyPassword", "password");
      System.out.println("finished proxy set up");
      try {
        URL myURL = new URL("http://google.com");
        URLConnection myURLConnection = myURL.openConnection();
        myURLConnection.connect();
    } catch (MalformedURLException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (Exception e) {
        e.printStackTrace();
    }
      System.out.println("trying to connect to a URL");
    // If something went wrong, log the error message.
    if (req.getParameter("error") != null) {
      LOG.severe("Something went wrong during auth: " + req.getParameter("error"));
      res.setContentType("text/plain");
      res.getWriter().write("Something went wrong during auth. Please check your log for details");
      return;
    }

    // If we have a code, finish the OAuth 2.0 dance
    if (req.getParameter("code") != null) {
      System.out.println("Got a code. Attempting to exchange for access token.");

      AuthorizationCodeFlow flow = AuthUtil.newAuthorizationCodeFlow();
      TokenResponse tokenResponse =
          flow.newTokenRequest(req.getParameter("code"))
              .setRedirectUri(WebUtil.buildUrl(req, "/oauth2callback")).execute();
      //Error is in the above line.

      // Extract the Google User ID from the ID token in the auth response
      String userId = ((GoogleTokenResponse) tokenResponse).parseIdToken().getPayload().getUserId();

以下是除此之外的日志

问题是您正在设置 HTTP 代理连接，但 OAuth 交换使用 HTTPS 连接。

至少，您需要为 HTTPS 设置代理信息，例如

systemProperties.setProperty( "https.proxyHost", "proxy server" );
systemProperties.setProperty( "https.proxyPort", "secure proxy port" );

你应该确保通过连接来测试它https://google.com/

但是，这是您可能需要做的最少的事情。现实情况是，它可以变得复杂得多。HTTPS 确实不是通过代理工作的，代理从根本上破坏了它背后的整个安全性。您可能需要设置许多其他东西，以便故意破坏安全控制，您真的不应该这样做。（但如果你必须这样做，它看起来像How do a send an HTTPS request through a proxy in Java?有几个你需要做的事情的指针。）

但老实说，这只是你的问题的开始。尽管这意味着您将能够通过代理发送内容，但 Mirror API 使用 web-hook 作为其几个函数的回调，并且这些回调也将通过 HTTPS。因此，您的代理还需要能够处理传入的 HTTPS 连接并将它们路由到您的服务器。

您可能需要考虑在 App Engine 上进行测试，因为这些问题会为您处理。
