Question

嗨，我是MVC的新手已经做了几年的网络表格。

当用户访问我们的网站时，他们已经通过我们组织的中央身份验证服务进行了身份验证。我们已经拥有SQL Server数据库中的所有用户，只需要匹配他们的身份并分配适当的授权。我自定义了https://aspnet.codeplex.com/SourceControl/latest#Samples/Identity/AspNet.Identity.MySQL/Readme.txt以用于我们现有的SQL Server。我收到“UserId not found”错误。这是堆栈跟踪：

[InvalidOperationException: UserId not found.]
   Microsoft.AspNet.Identity.<GetSecurityStampAsync>d__42.MoveNext() +651
   System.Runtime.CompilerServices.TaskAwaiter.ThrowForNonSuccess(Task task) +144
   System.Runtime.CompilerServices.TaskAwaiter.HandleNonSuccessAndDebuggerNotification(Task task) +84

   Security.Controllers.<Login>d__10.MoveNext() in T:\Security\Controllers\AccountController.cs:77

以下是IdentityModel.cs中发生错误的地方：

 public async Task<ClaimsIdentity> GenerateUserIdentityAsync(UserManager<ApplicationUser> manager)
    {
        var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);

以下是我的AccountController.cs代码基于： ASP.NET MVC Identity login without password

    var user = await UserManager.FindByNameAsync(id);

    var result = await UserManager.CreateAsync(user);
    if (result.Succeeded)
    {
        await SignInManager.SignInAsync(user, isPersistent: true, rememberBrowser: true);
    }

Answer 1

如果您有用户ID更改等待UserManager.FindByNameAsync（id） - ＆gt;等待UserManager.FindByIdAsync（Id）

FindByNameAsync - ＆gt;正在寻找匹配的用户名

Answer 2

您好，您可以使用此方法UserManager.FindByIdAsync Method，它将按ID查找用户。

例如：

 var user = await UserManager.FindByIdAsync(userid);

Answer 3

我删除了

var userIdentity = await manager.CreateIdentityAsync(this, DefaultAuthenticationTypes.ApplicationCookie);

并将其替换为

    var userIdentity = new ClaimsIdentity(new[]
        {
                // adding following 2 claims for supporting default antiforgery provider
                new Claim(ClaimTypes.NameIdentifier, this.UserName),
                new Claim("http://schemas.microsoft.com/accesscontrolservice/2010/07/claims/identityprovider", "ASP.NET Identity", "http://www.w3.org/2001/XMLSchema#string"),
                new Claim(ClaimTypes.Name, this.UserName),
                new Claim("AspNet.Identity.SecurityStamp", this.SecurityStamp),
                //new Claim(ClaimTypes.Role, AppRoleClaims.Client),
                new Claim(ClaimTypes.Sid, this.Id.ToString())
        },
    DefaultAuthenticationTypes.ApplicationCookie);

我在How can I log a Client in Asp.Net MVC with no user找到了此代码。它似乎已经解决了我遇到的问题。

在现有MS SQL Server中使用aspnet Identity，找不到UserId错误
