我试图制作一个过滤器来阻止未登录的用户访问某些页面.为此,我使用以下doFilter方法创建了一个过滤器类

HttpServletRequest request = (HttpServletRequest) req;
HttpServletResponse response = (HttpServletResponse) res;
String url = request.getRequestURI();
boolean allowedRequest = false;

System.out.println(url);

if(urlList.contains(url)) {
    allowedRequest = true;
    System.out.println("in list");
}

if (!allowedRequest) {
    Object o = request.getSession().getAttribute("UserInfo");
    if (null == o) {
        System.out.println("Hey i am in");
        response.sendRedirect("/login.jsp");
    }
}

chain.doFilter(req, res);

} // end of doFilter

为了允许不需要用户登录的页面我在init()中创建了一个arraylist url-list

现在发生了一件非常奇怪的蠢事.假设我有两页home.jsp和dcr.jsp.当我尝试访问home.jsp而没有登录时,我成功地重定向到login.jsp,但是当我试图访问dcr.jsp时它没有被重定向,尽管它进入循环if(null == o)我能理解因为我在控制台中打印该行.THis是我在服务器中获得的输出这是我在服务器中获得的输出

/dcrmaintenance.jsp

Hey i am in

这告诉我null == o是真的.

页面dcr.jsp访问一个会话对象,由于用户没有登录,它正在按预期获得java.lang.NullPointerException但我无法理解为什么即使进入循环后重定向也没有发生.如果有人可以在哪里我犯了一个错误,我将不胜感激.

我写了这段代码来创建一个redis客户端实例

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using ServiceStack.Redis;
using ServiceStack;



class Program
{
    static void Main(string[] args)
    {
        RedisClient a = new RedisClient();
         .....

但在尝试构建解决方案时,我收到了此警告

'The referenced assembly "ServiceStack.Redis" could not be resolved because                                   it has a dependency on "System.ServiceModel.Web, Version=4.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" which is not in the currently targeted framework ".NETFramework,Version=v4.0,Profile=Client". Please remove references to assemblies not in the targeted framework or consider retargeting your project.'

和错误

我有这个json转储,它没有很好的缩进,当我只是写入一个文件时不可读,所以为了使它更具可读性我做了这个

 with open(responseFile, 'w') as outfile:
      outfile.write(dumps(loads(content), indent=4))

但现在我得到这个无效\转义:错误.有什么建议 ？

例如内容:
