Dotnetopenauth使用自定义身份提供商进行单点登录

tgg*_*ggm 12 asp.net-mvc dotnetopenauth asp.net-mvc-4

我正在尝试设置DotNetOpenAuth示例,以便为自定义提供程序提供可用的SSO解决方案.我正在使用OpenIdProviderMvc示例项目,看起来工作正常.

我的问题是设置"消费者",在这种情况下是OpenIdRelyingPartyMvc示例项目,我无法将其配置为使用OpenIdProvider.

我试图在消费者的web.config上设置一个端点,如下所示:

<trustedProviders rejectAssertionsFromUntrustedProviders="true">
    <add endpoint="http://localhost:4864/OpenID/Provider" />
</trustedProviders>

但我得到的是"找不到OpenID端点".错误(实际上,我不太确定在OpenID框上放什么......)

该项目几乎没有记录.有人能指出我正确的方向吗？

至少让供应商和消费者互相工作和交谈？

让我们开始吧:

1-打开Visual Studio 2010转到文件>新建>项目> Web> ASP.NET MVC 3应用程序:

2- 下载Assets文件夹,它包含我们将使用的DotNetOpenAuth dll和OpenID-Selector文件,

如果您想要参加这些项目并更详细地发现它们,请随意.

将其解压缩到所需的文件夹

  a - Add the DotNetOpenAuth.dll to references in your site.

  b- Delete all files/folders in Site Content folder.

  c- Copy Assets Content files/folders to the site Content .

  d- Copy the  Assets Script files to the site Script.

3-转到视图>共享> _Layout.cshtml并替换为这个新头,我们刚刚添加了新的样式和脚本:

<head>
    <title>@ViewBag.Title</title>
    <link href="@Url.Content("~/Content/Site.css")" 
     rel="stylesheet" type="text/css" />
    <script src="@Url.Content("~/Scripts/jquery-1.4.4.min.js")"
     type="text/javascript"></script>
    <link href="@Url.Content("~/Content/openid-shadow.css")"
     rel="stylesheet" type="text/css" />
    <link href="@Url.Content("~/Content/openid.css")" 
     rel="stylesheet" type="text/css" />
    <script src="@Url.Content("~/Scripts/openid-en.js")"

    <script src="@Url.Content("~/Scripts/openid-jquery.js")" 
     type="text/javascript"></script>
    <script type="text/javascript">
        $(document).ready(function () {
            openid.init('openid_identifier');
        });
    </script>
</head>

4-转到Models> AccountModels.cs,导航到公共类LogOnModel

并添加OpenID属性,我们将使用它来保存从OpenID-Selector返回的OpenID

你的班级将如下所示:

public class LogOnModel
{
    [Display(Name = "OpenID")]
    public string OpenID { get; set; }

    [Required]
    [Display(Name = "User name")]
    public string UserName { get; set; }

    [Required]
    [DataType(DataType.Password)]
    [Display(Name = "Password")]
    public string Password { get; set; }

    [Display(Name = "Remember me?")]
    public bool RememberMe { get; set; }
}

导航到公共类RegisterModel和Add OpenID属性

public class RegisterModel
{

    [Display(Name = "OpenID")]
    public string OpenID { get; set; }

    [Required]
    [Display(Name = "User name")]
    public string UserName { get; set; }

    [Required]
    [DataType(DataType.EmailAddress)]
    [Display(Name = "Email address")]
    public string Email { get; set; }

    [Required]
    [ValidatePasswordLength]
    [DataType(DataType.Password)]
    [Display(Name = "Password")]
    public string Password { get; set; }

    [DataType(DataType.Password)]
    [Display(Name = "Confirm password")]
    [Compare("Password", ErrorMessage =
    "The password and confirmation password do not match.")]
    public string ConfirmPassword { get; set; }
}

然后转到AccountModels.cs中的Services部分

并修改CreateUser和Add GetUser以通过您的Interface OpenID获取用户

将会是这样的:

public interface IMembershipService
{
    int MinPasswordLength { get; }
    bool ValidateUser(string userName, string password);
    MembershipCreateStatus CreateUser(string userName, string password,
                                      string email, string OpenID);
    bool ChangePassword(string userName, string oldPassword, string newPassword);
    MembershipUser GetUser(string OpenID);
}

将这些使用添加到AccountModels.cs

using System.Security.Cryptography;
using System.Text;

Run Code Online (Sandbox Code Playgroud)

然后将此函数添加到AccountModels.cs,此函数将用于将OpenID转换为GUID

注意:随意对您的系统使用更好的散列,MD5有一些碰撞问题.

public Guid StringToGUID(string value)
{
    // Create a new instance of the MD5CryptoServiceProvider object.
    MD5 md5Hasher = MD5.Create();
    // Convert the input string to a byte array and compute the hash.
    byte[] data = md5Hasher.ComputeHash(Encoding.Default.GetBytes(value));
    return new Guid(data);
}

还修改CreateUser函数,如下所示:

public MembershipCreateStatus CreateUser(string userName, string password, 
                                         string email , string OpenID)
{
    if (String.IsNullOrEmpty(userName)) throw 
    new ArgumentException("Value cannot be null or empty.", "userName");
    if (String.IsNullOrEmpty(password)) throw 
    new ArgumentException("Value cannot be null or empty.", "password");
    if (String.IsNullOrEmpty(email)) throw
    new ArgumentException("Value cannot be null or empty.", "email");

    MembershipCreateStatus status;
    _provider.CreateUser(userName, password, email, null, null, true,
                            StringToGUID(OpenID), out status);
    return status;
}

这里我们使用MemberShip ProviderUserKey来存储OpenID,以及我们将OpenID字符串转换为GUID以供CreateUser和GetUser方法使用的技巧.

现在让我们将此函数添加到AccountModels.cs,它将通过OpenID获取用户:

public MembershipUser GetUser(string OpenID)
{
    return _provider.GetUser(StringToGUID(OpenID), true);
}

5-转到Views> Account> LogOn.cshtml

用这个替换所有标记,我们将OpenID-Selector集成到LogOn视图:

@model OpenIDMVC3.Models.LogOnModel
@{
    ViewBag.Title = "Log On";
}
