C#读取Javascript写的Cookie

[枝柳飞扬]

我用Javascript写的Cookie，用Javascript可以读到，可是C#读不到Cookie，请问啥原因？

function setCookie(name, value, hours) {
var expire = "";
if (hours != null) {
expire = new Date((new Date()).getTime() + hours * 3600000);
expire = "; expires=" + expire.toGMTString();
}
document.cookie = escape(name) + "=" + escape(value) + expire;
}


C#读：
HttpCookieCollection cookies = Request.Cookies;
foreach (string c in cookies)
{
Response.Write(c);
}

foreach (string cookieName in Request.Cookies.AllKeys)
{
HttpCookie cookie = Request.Cookies[cookieName];
}

@wuyq11
我那样写也可以执行，就是看cookies里有没有的，
用Request.Cookies[cookieName] 获得的为 NULL 。

兄台试下这个方式，把你的cooiename传进去就可以了

 
    protected string getCookie(string cookiename)
    {
        string strcookievalue = "";
        HttpCookie cookie = HttpContext.Current.Request.Cookies[cookiename];
        if (cookie != null)
        {
            strcookievalue = cookie.Value;
        }
        return strcookievalue ;
    }

观望……

foreach (string c in cookies)
这句对吗

[aoin2006]

if(Response.Cookies["userName"] != null)
Response.Write(Response.Cookies["userName"].Value);

javascript写的时间和你在后台读取的时间可能冲突

我的意思是你在前台还没写进去 。 后台就开始读取了

你用2个页面测试一下 第一个用前台写 第二个用后台读


function setname() {
var Days = 30;
var exp = new Date();
exp.setTime(exp.getTime() + Days * 24 * 60 * 60 * 1000);
document.cookie = "userName=" + escape(Form1.txtUsername.value) + ";expires=" + exp.toGMTString() + ";path=/";
}


写的时候 加上 path=/
