删除cookie

Question

如何使用servlet从客户端浏览器中删除cookie？

 HttpSession ses=request.getSession(false); 
     Cookie c[]=request.getCookies(); 

     for (int i=0; i<c.length; i++) //Removing cookie, if present 
     { 
      if(c[i].getName().equals("UserID")) 
      { 
       System.out.println(c[i].getValue()+" is logging out --- Cookie Set to expire!"); 
       c[i].setMaxAge(0); 
       response.addCookie(c[i]); 
       break; 
      } 
     } 

有没有删除它的任何其他方式????

Answer 1

setMaxAge(0)是删除cookie的唯一方法。这是更好地设置这些cookie的性能，同时删除：

• 路径

• 域

  Cookie c[]=request.getCookies(); 
  
  for (int i=0; i<c.length; i++) //Removing cookie, if present 
  { 
      if(c[i].getName().equals("UserID")) 
      { 
       System.out.println(c[i].getValue()+" is logging out --- Cookie Set to expire!"); 
       c[i].setMaxAge(0); 
       c[i].setPath(path); 
       c[i].setDomain(domain); 
       response.addCookie(c[i]); 
       break; 
      } 
  }
