如何解密自定义URL重写提供程序内的cookie？ [英] How to decrypt the cookie inside custom URL rewrite provider?

问题描述

我有一个网站，其中我创建了一个自定义cookie，并且我试图读取运行在IIS中的自定义重写提供程序中的cookie值

问题：解密自定义网址重写提供程序中的Cookie？

下面是用于创建自定义Cookie的代码：

  FormsAuthenticationTicket ticket = new FormsAuthenticationTicket（
 1，
 model.Email，
 DateTime.Now，
 DateTime.Now。 AddDays（7），
 true，
deepak，
 FormsAuthentication.FormsCookiePath）; 
 
 string encryptedTicket = FormsAuthentication.Encrypt（ticket）; 
 HttpCookie fCookie = new HttpCookie（customCookie，encryptedTicket）; 
 fCookie.Expires = DateTime.Now.AddDays（7）; 
 fCookie.Path =/; 
 Response.Cookies.Add（fCookie）; 
  

以下代码是读取IIS中运行的自定义重写提供程序中的cookie值

  public class ParseUserNameProvider：IRewriteProvider，IProviderDescriptor 
 {
 public IEnumerable< SettingDescriptor> GetSettings（）
 {
 throw new NotImplementedException（）; 
} 
 
 public void Initialize（IDictionary< string，string> settings，IRewriteContext rewriteContext）
 {} 
 
 public string重写b $ b {
 string [] val = value.Split（'='）; 
 string name =; 
 if（val！= null）
 {
 FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt（val [1]）; 
 if（authTicket！= null）
 {
 name = authTicket.Name; 
} 
} 
返回名称; 
} 
}

注意：此帖子不是 URL重写模块的自定义重写提供者，因为我得到不同的错误。

解决方案

如果有任何其他Cookie的域，他们将作为val [1]的一部分包含在一个长字符串。我有相当的困难使IIS可靠地通过只有一个cookie，所以我把所有的cookie拉到val [1]字符串，然后拆分成一个所有的cookie值的数组，然后只是选择我需要的一个。如果有疑问，您的提供程序会把val [1]字符串作为客户错误，以便您可以看到它看到了什么。

  throw new Exception（val [1]）; 
  

一旦你可以看到实际收到的内容，你就会知道如何分割。

I have a website where I created a custom cookie and I am trying to read the cookie value inside my Custom Rewrite Provider running in IIS

Question in short: How to decrypt the cookie inside custom URL rewrite provider?

Below is the code for creating custom cookie

     FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(
           1,                                    
           model.Email,                          
           DateTime.Now,                          
           DateTime.Now.AddDays(7),          
           true,                         
           "deepak",                             
           FormsAuthentication.FormsCookiePath);  

        string encryptedTicket = FormsAuthentication.Encrypt(ticket);
        HttpCookie fCookie = new HttpCookie("customCookie", encryptedTicket);
        fCookie.Expires = DateTime.Now.AddDays(7);
        fCookie.Path = "/";
        Response.Cookies.Add(fCookie);

Below code is to read the cookie value inside my Custom Rewrite Provider running in IIS

   public class ParseUserNameProvider : IRewriteProvider, IProviderDescriptor
   {
    public IEnumerable<SettingDescriptor> GetSettings()
    {
        throw new NotImplementedException();
    }

    public void Initialize(IDictionary<string, string> settings, IRewriteContext rewriteContext)
    {}

    public string Rewrite(string value)
    {
        string[] val = value.Split('=');
        string name = "";
        if (val != null)
        {
            FormsAuthenticationTicket authTicket = FormsAuthentication.Decrypt(val[1]);
            if(authTicket!=null)
            {
                name = authTicket.Name;
            }
        }
        return name;
    }
}

Error raised as shown below

I learned this from : http://www.iis.net/learn/extensions/url-rewrite-module/developing-a-custom-rewrite-provider-for-url-rewrite-module

Note: This post is NOT duplicate of Custom Rewrite Provider for URL Rewrite Module because I am getting different error.

解决方案

If there are any other Cookies with that domain they'll be included as part of val[1] in one long string. I had considerable difficulty making IIS reliably pass through just one cookie so I pulled though all the cookies into val[1] string and then split that into an array of all the cookie values then just selected the one I needed. If in doubt get your provider to out put the val[1] string as a customer error so you can see what it's seeing.

        throw new Exception(val[1]);

Once you can see what's actually being received you work out how you need to split it.
