未在asp.net MVC中设置Cookie [英] Cookie not setting in asp.net mvc

问题描述

if (HttpContext.Request.Cookies["time"]==null)
{
    HttpCookie cookie = new HttpCookie("last_visited",DateTime.Now.ToString());
    cookie.Expires = DateTime.Now.AddDays(10);
    HttpContext.Response.Cookies.Add(cookie);
}
else if(HttpContext.Request.Cookies["last_visited"]!=null)
{
    ViewBag.last_visited = HttpContext.Request.Cookies["last_visited"].Value;
}

我正在尝试在asp.net mvc中设置cookie。上面是我在contoller动作中的代码。这段代码的目的是在没有cookie的情况下设置cookie，在有cookie的情况下读取值。

I am trying to set a cookie in asp.net mvc. Above is my code in the contoller action. The purpose of this code is to set a cookie if there is none and read a value if there is a cookie set.

但是在设置断点后，我发现了else如果部分永远不会执行，就好像根本没有设置cookie。

However the after setting the breakpoint i discovered the else if part is never getting executed as if the cookie isn't being set up at all.

这里出了什么问题？

推荐答案

第一个if语句是否正在检查错误的cookie？应该将时间 改为最后一次访问 ？

Is it that the first if statement is checking the wrong cookie? Should "time" be "last_visited" instead?

固定代码：

if (HttpContext.Request.Cookies["last_visited"]==null)
{
    HttpCookie cookie = new HttpCookie("last_visited",DateTime.Now.ToString());
    cookie.Expires = DateTime.Now.AddDays(10);
    HttpContext.Response.Cookies.Add(cookie);
}
else if(HttpContext.Request.Cookies["last_visited"]!=null)
{
    ViewBag.last_visited = HttpContext.Request.Cookies["last_visited"].Value;
}
