cas方面的问题，怎了半天都没有解决

Question

11:10:04.957 DEBUG org.jasig.cas.client.util.CommonUtils 291 safeGetParameter - safeGetParameter called on a POST HttpServletRequest for LogoutRequest. Cannot complete check safely. Reverting to standard behavior for this Parameter这个提示是啥意思？该如和破？

Answer 1

源代码意思是：要么这个请求是GET请求，要么这个请求是post，那么post表单变量列表里必须包含一个固定名称的参数，这个固定参数是什么看看你业务逻辑设计思路。

 public static String safeGetParameter(final HttpServletRequest request, final String parameter,
        final List<String> parameters) {
    if ("POST".equals(request.getMethod()) && parameters.contains(parameter)) {
        LOGGER.debug("safeGetParameter called on a POST HttpServletRequest for Restricted Parameters.  Cannot complete check safely.  Reverting to standard behavior for this Parameter");
        return request.getParameter(parameter);
    }
    return request.getQueryString() == null || !request.getQueryString().contains(parameter) ? null : request
            .getParameter(parameter);
}
