asp.net-mvc – Dotnetopenauth使用自定义身份提供者单点登录

我正在尝试设置DotNetOpenAuth示例以使用自定义提供程序提供一个可用的SSO解决方案.我正在使用OpenIdProviderMvc示例项目,它似乎工作正常.

我的问题是设置“消费者”,在这种情况下,OpenIdRelyingPartyMvc示例项目,我无法配置它使用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>

但是我得到的只是“没有找到OpenID端点”.错误(实际上,我不太确定放在OpenID框上…)

这个项目几乎没有文件.有人可以指向正确的方向吗？

至少要有一个供应商和消费者互相工作和交谈？

解决方法

让我们开始吧

1-打开Visual Studio 2010转到文件>新>项目>网络> ASP.NET MVC 3应用：

那么选择Internet应用程序一定要把Razor看作是你的View引擎,然后点击Ok：

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

如果你想去这些项目,并发现更多的细节,请随时随地.

将其提取到您想要的文件夹

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.

您的项目将如下所示：

3-转到视图>共享> _Layout.cshtml并用这个新的头替换,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")" 
     type="text/javascript"></script>
    <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-转到模型> AccountModels.cs,导航到公共类logonModel

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

你的课程将如下所示：

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并添加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“服务”部分

并修改CreateUser并添加GetUser以通过OpenID(您的Interface)获取用户

将如下所示：

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);
}

将它们添加到AccountModels.cs中

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

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

注意：随时使用更好的哈希系统,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);
}

还要修改CreateUser函数,如下所示：

public MembershipCreateStatus CreateUser(string userName,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,true,StringToGUID(OpenID),out status);
    return status;
}

在这里,我们使用MemberShip ProviderUserKey存储OpenID和这里的技巧,我们将OpenID字符串转换为GUID以供CreateUser和GetUser方法使用.

现在让我们将这个函数添加到AccountModels.cs中,这将通过OpenID获取用户：

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

5-去视图>帐户> logon.cshtml

用这个替换所有的标记,我们正在将OpenID-Selector集成到logon视图中：

@model OpenIDMVC3.Models.logonModel
@{
    ViewBag.Title = "Log On";
}
<h2>
    Log On</h2>
<p>
    Please enter your username and password. @Html.ActionLink("Register","Register")
    if you don't have an account.
</p>
<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" type="text/javascript">
</script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")"
   type="text/javascript"></script>
<form action=
"Authenticate?ReturnUrl=@HttpUtility.UrlEncode(Request.QueryString["ReturnUrl"])"
 method="post" id="openid_form">
<input type="hidden" name="action" value="verify" />
<div>
    <fieldset>
        <legend>Login using OpenID</legend>
        <div class="openid_choice">
            <p>
                Please click your account provider:</p>
            <div id="openid_btns">
            </div>
        </div>
        <div id="openid_input_area">
            @Html.TextBox("openid_identifier")
            <input type="submit" value="Log On" />
        </div>
        <noscript>
            <p>
                OpenID is service that allows you to log-on to many different websites 
                using a single indentity. Find out <a href="http://openid.net/what/">
                 more about OpenID</a>and <a href="http://openid.net/get/">
                 how to get an OpenID enabled account</a>.</p>
        </noscript>
        <div>
            @if (Model != null)
            {
                if (String.IsNullOrEmpty(Model.UserName))
                {
                <div class="editor-label">
                    @Html.LabelFor(model => model.OpenID)
                </div>
                <div class="editor-field">
                    @Html.DisplayFor(model => model.OpenID)
                </div>
                <p class="button">
                    @Html.ActionLink("New User,Register","Register",new { OpenID = Model.OpenID })
                </p>
                }
                else
                {
                    //user exist 
                <p class="buttonGreen">
                    <a href="@Url.Action("Index","Home")">Welcome,@Model.UserName,Continue..." </a>
                </p>

                }
            }
        </div>
    </fieldset>
</div>
</form>

@Html.ValidationSummary(true,"Login was unsuccessful. Please correct the errors 
                                                    and try again.")
@using (Html.BeginForm())
{
    <div>
        <fieldset>
            <legend>Or Login Normally</legend>
            <div class="editor-label">
                @Html.LabelFor(m => m.UserName)
            </div>
            <div class="editor-field">
                @Html.TextBoxFor(m => m.UserName)
                @Html.ValidationMessageFor(m => m.UserName)
            </div>
            <div class="editor-label">
                @Html.LabelFor(m => m.Password)
            </div>
            <div class="editor-field">
                @Html.PasswordFor(m => m.Password)
                @Html.ValidationMessageFor(m => m.Password)
            </div>
            <div class="editor-label">
                @Html.CheckBoxFor(m => m.RememberMe)
                @Html.LabelFor(m => m.RememberMe)
            </div>
            <p>
                <input type="submit" value="Log On" />
            </p>
        </fieldset>
    </div>
}

6-现在让我们运行该项目,然后点击[登录]链接,你会得到这样的页面：

7-转到控制器> AccountController.cs并添加以下使用：

using DotNetOpenAuth.Messaging;
using DotNetOpenAuth.OpenId;
using DotNetOpenAuth.OpenId.Extensions.SimpleRegistration;
using DotNetOpenAuth.OpenId.RelyingParty;
using DotNetOpenAuth.OpenId.Extensions.AttributeExchange;

然后将此属性添加到AccountController.cs中：

private static OpenIdRelyingParty openid = new OpenIdRelyingParty();

然后将此函数添加到AccountController.cs中：

[ValidateInput(false)]
public ActionResult Authenticate(string returnUrl)
{
    var response = openid.GetResponse();
    if (response == null)
    {
        //Let us submit the request to OpenID provider
        Identifier id;
        if (Identifier.TryParse(Request.Form["openid_identifier"],out id))
        {
            try
            {
                var request = openid.CreateRequest(
                                        Request.Form["openid_identifier"]);
                return request.RedirectingResponse.AsActionResult();
            }
            catch (ProtocolException ex)
            {
                ViewBag.Message = ex.Message;
                return View("logon");
            }
        }

        ViewBag.Message = "Invalid identifier";
        return View("logon");
    }

    //Let us check the response
    switch (response.Status)
    {

        case AuthenticationStatus.Authenticated:
            logonModel lm = new logonModel();
            lm.OpenID = response.ClaimedIdentifier;
            // check if user exist
            MembershipUser user = MembershipService.GetUser(lm.OpenID);
            if (user != null)
            {
                lm.UserName = user.UserName;
                FormsService.SignIn(user.UserName,false);
            }

            return View("logon",lm);

        case AuthenticationStatus.Canceled:
            ViewBag.Message = "Canceled at provider";
            return View("logon");
        case AuthenticationStatus.Failed:
            ViewBag.Message = response.Exception.Message;
            return View("logon");
    }

    return new EmptyResult();
}

8 – 现在运行项目单击[登录]链接,然后单击Google提供程序

它可能会要求您登录或要求您允许访问您的信息

你会得到一个这样的页面：

您可以看到它显示您的OpenID和一个指示这是尚未注册的新用户的按钮,

在[新用户,注册]按钮之前,我们需要修改注册表视图和控制器来访问OpenID信息.

9-转到控制器> AccountController.cs替换[ActionResult Register()]：

public ActionResult Register(string OpenID)
{
    ViewBag.PasswordLength = MembershipService.MinPasswordLength;
    ViewBag.OpenID = OpenID;
    return View();
}

并修改[ActionResult Register(RegisterModel model)]来使用OpenID

创建用户：

[HttpPost]
public ActionResult Register(RegisterModel model)
{
    if (ModelState.IsValid)
    {
        // Attempt to register the user
        MembershipCreateStatus createStatus =
        MembershipService.CreateUser(model.UserName,model.Password,model.Email,model.OpenID);

        if (createStatus == MembershipCreateStatus.Success)
        {
            FormsService.SignIn(model.UserName,false);
            return RedirectToAction("Index","Home");
        }
        else
        {
            ModelState.AddModelError("",AccountValidation.ErrorCodeToString(createStatus));
        }
    }

    // If we got this far,something Failed,redisplay form
    ViewBag.PasswordLength = MembershipService.MinPasswordLength;
    return View(model);
}

10-转到视图>帐户> Register.cshtml,用以下替换标记：

@model OpenIDMVC3.Models.RegisterModel
@{
    ViewBag.Title = "Register";
}

<h2>Create a New Account</h2>
<p>
    Use the form below to create a new account. 
</p>
<p>
    Passwords are required to be a minimum of @ViewBag.PasswordLength 
    characters in length.
</p>

<script src="@Url.Content("~/Scripts/jquery.validate.min.js")" 
  type="text/javascript"></script>
<script src="@Url.Content("~/Scripts/jquery.validate.unobtrusive.min.js")"
   type="text/javascript"></script>

@using (Html.BeginForm()) {
    @Html.ValidationSummary(true,"Account creation was unsuccessful.
                                            Please correct the errors and try again.")
    <div>
        <fieldset>
            <legend>Account Information</legend>
            @if (ViewData["OpenID"] != null)
            {
            <div class="editor-label">
                @Html.Label("OpenID")
            </div>
            <div class="editor-label">
                @Html.Label((string)ViewBag.OpenID)
            </div>
            }
            <div class="editor-label">
                @Html.LabelFor(m => m.UserName)
            </div>
            <div class="editor-field">
                @Html.TextBoxFor(m => m.UserName)
                @Html.ValidationMessageFor(m => m.UserName)
            </div>

            <div class="editor-label">
                @Html.LabelFor(m => m.Email)
            </div>
            <div class="editor-field">
                @Html.TextBoxFor(m => m.Email)
                @Html.ValidationMessageFor(m => m.Email)
            </div>

            <div class="editor-label">
                @Html.LabelFor(m => m.Password)
            </div>
            <div class="editor-field">
                @Html.PasswordFor(m => m.Password)
                @Html.ValidationMessageFor(m => m.Password)
            </div>

            <div class="editor-label">
                @Html.LabelFor(m => m.ConfirmPassword)
            </div>
            <div class="editor-field">
                @Html.PasswordFor(m => m.ConfirmPassword)
                @Html.ValidationMessageFor(m => m.ConfirmPassword)
            </div>

            <p>
                <input type="submit" value="Register" />
            </p>
        </fieldset>
    </div>
}

11 – 转到步骤8,让我们点击[新用户,注册]按钮,你会得到这个：

12-注册您想要的任何帐户,您将会喜欢这个页面：

13-点击[注销]并使用相同的OpenID重新登录,你将会看到这样的页面：

您可以看到欢迎绿色按钮检测到该用户已注册.

14-点击绿色按钮,你会得到一个这样的页面：

恭喜！现在,您已将OpenID集成到您的项目中.
