Question

我的问题必须有一个简单的答案，我确定我错过了一些明显的东西......有人可以为我指出它吗？

当我在手机上运行应用程序时，广播组的行为正常（意味着错误答案的分数为0，正确答案的分数为1）但是如果我点击了错误答案，则返回要正确答案并重新提交，它会为分数增加一个。所以同样的问题只会显示两点，只是点击两次正确答案......

Answer 1

您只需在@Override public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException { HttpServletRequest httpRequest = (HttpServletRequest) req; HttpServletResponse response = (HttpServletResponse) res; if (!ENVIRONMENT_DEV.equalsIgnoreCase(environment)) { ispUtility = ISPUtils.getInstance(); ispFileProvider = ispUtility.getTempFileUtility(); String originAddress = httpRequest.getHeader("Origin"); if (originAddress != null) { if (originAddress.toLowerCase().contains(ispFileProvider.getIspDomainName().toLowerCase())) { log.info("Origin Match Found: "+originAddress.replaceAll("\r\n", "")); response.setHeader("Access-Control-Allow-Origin", originAddress.replaceAll("\r\n", "")); } else { response.setHeader("Access-Control-Allow-Origin", "https://localhost:8001"); } } } else { response.setHeader("Access-Control-Allow-Origin", "*"); } response.setHeader("Access-Control-Allow-Methods", "GET, POST, OPTIONS"); response.setHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept, Authorization, x-auth-token"); response.setHeader("Access-Control-Expose-Headers", "x-auth-token"); response.setHeader("Access-Control-Max-Age", "3600"); try { chain.doFilter(req, res); } catch (IOException e) { log.error("IOException Occurred :" + e.getMessage()); } catch (ServletException e) { log.error("IOException Occurred :" + e.getMessage()); } } @Override public void init(FilterConfig filterConfig) { } @Override public void destroy() { }中添加1，因此每次更改状态并获得正确答案时，您需要再添加一个。如果检查错误的数字或将其设置为1

，则必须减少baseScore

Answer 2

@Emily你的问题在切换的情况下有很多错误你在if条件中添加了分号，我不知道为什么，因为在这种情况下有一个if语句是没有意义的。

在选中已更改后，您将添加已经得分为1的变量。

我的建议是你最好采用一个全局变量来跟踪得分。
