在Asp.Net的另一个应用程序中读取一个cookie

Question

我在Asp.Net中有一个应用程序，点击一个按钮它应该启动另一个映射应用程序。在该应用程序中，用户名和Email等用户的凭据是必需的。所以，我试图设置一个cookie并将该cookie的域名修复到该应用程序，但我无法在该应用程序中看到该cookie。我不确定发生了什么问题，或者如果我在Cookie中犯了一些错误。

  MembershipUser usr = Membership.GetUser(); 
    Guid newUserId = (Guid)usr.ProviderUserKey; 
    HttpCookie SampleCookie = new HttpCookie("UserInfo"); 
    Response.Cookies["UserInfo"]["UserName"] = usr.UserName; 
    Response.Cookies["UserInfo"]["Email"] = usr.Email; 
    SampleCookie.Expires = DateTime.Now.AddDays(1); 
    Response.Cookies.Add(SampleCookie); 
    SampleCookie.Domain = "http://157.182.212.204/MAP"; 

再次感谢您的帮助。

代码地图应用：

  function Get_Cookie(check_name) { 
      // first we'll split this cookie up into name/value pairs 
      // note: document.cookie only returns name=value, not the other components 

      var a_all_cookies = document.cookie.split(';'); 
      var a_temp_cookie = ''; 
      var cookie_name = ''; 
      var cookie_value = ''; 
      var b_cookie_found = false; // set boolean t/f default f 

      for (i = 0; i < a_all_cookies.length; i++) 
      { 
       // now we'll split apart each name=value pair 
       a_temp_cookie = a_all_cookies[i].split('='); 


       // and trim left/right whitespace while we're at it 
       cookie_name = a_temp_cookie[0].replace(/^\s+|\s+$/g, ''); 

       // if the extracted name matches passed check_name 
       if (cookie_name == check_name) 
       { 
        b_cookie_found = true; 
        // we need to handle case where cookie has no value but exists (no = sign, that is): 
        if (a_temp_cookie.length > 1) 
        { 
         cookie_value = unescape(a_temp_cookie[1].replace(/^\s+|\s+$/g, '')); 
        } 
        // note that in cases where cookie is initialized but no value, null is returned 
        return cookie_value; 
        break; 
       } 
       a_temp_cookie = null; 
       cookie_name = ''; 
      } 
      if (!b_cookie_found) 
      { 
       return null; 
      } 
     } 

     function Delete_Cookie(name, path, domain) { 
      if (Get_Cookie(name)) document.cookie = name + "=" + 
        ((path) ? ";path=" + path : "") + 
        ((domain) ? ";domain=" + domain : "") + 
        ";expires=Thu, 01-Jan-1970 00:00:01 GMT"; 
     } 

        alert(Get_Cookie("UserName"));

至于麻烦用你设置你的cookie的方式......除非你已经将它添加到响应中，否则你不会在响应中找到cookie。 （如果你找到它，你只需在几行之后重写这个cookie）。只需直接编辑cookie，然后添加到cookie jar。我也相信MAP应该在cookie的路径属性中（不知道它有多大的差异）。据我所知，你不需要在域中的http（再次，不知道浏览器是否足够聪明来处理）。

MembershipUser usr = Membership.GetUser(); 
    Guid newUserId = (Guid)usr.ProviderUserKey; 
    HttpCookie sampleCookie = new HttpCookie("UserInfo"); 
    sampleCookie["UserName"] = usr.UserName; 
    sampleCookie["Email"] = usr.Email; 
    sampleCookie.Expires = DateTime.Now.AddDays(1); 
    sampleCookie.Domain = "157.182.212.204"; 
    sampleCookie.Path = "/MAP"; 
    Response.Cookies.Add(sampleCookie); 

Cookie只能设置为当前FQDN的“尾部”的域。因此，如果您当前的FQDN不是157.182.212.204，则cookie不会在浏览器中设置。例如，尾巴，我的意思是http://overflow.acme.com可以为overflow.acme.com或acme.com设置cookie，但不能为fubar.acme.com或fubar.com设置Cookie。

我的猜测是，如果您的应用程序与MAP应用程序位于不同的FQDN上，则需要采用不同的方式将用户名和电子邮件传递给地图应用程序（可能发布到页面在地图应用程序，可以设置Cookie，然后重定向到相应的页面

更新您发布更多的代码后：

试试这个：

SampleCookie.Domain = "157.182.212.204"; 
    SampleCookie.Path = "/MAP"; 
    Response.Cookies.Add(SampleCookie); 

    Response.Redirect("http://157.182.212.204/MAP/index.html", false); 

在response.redirect上设置false应该会导致设置的cookie标头通过。如果渲染事件中有任何东西，您可能需要短路页面中的其他逻辑

或者只是将查询字符串中的内容传递给您。你不使用HttpOnly cookies（所以用户可以注入cookie）。
