ASP.NET 5 vNext依赖项注入(RoleManager) [英] ASP.NET 5 vNext Dependencies Injection (RoleManager)
问题描述
我正在尝试将UserManager之类的RoleManager传递给我的控制器，但出现此错误:
I'm trying to pass to my controller the RoleManager like UserManager, but I have this error:
处理请求时发生未处理的异常.
An unhandled exception occurred while processing the request.
InvalidOperationException:无法解析类型的服务 'Microsoft.AspNet.Identity.RoleManager`1 [Web.MongoDBIdentitySample.Models.ApplicationRole]' 尝试激活时 "Web.MongoDBIdentitySample.Controllers.AccountController".
InvalidOperationException: Unable to resolve service for type 'Microsoft.AspNet.Identity.RoleManager`1[Web.MongoDBIdentitySample.Models.ApplicationRole]' while attempting to activate 'Web.MongoDBIdentitySample.Controllers.AccountController'.
这是我的ConfigureServices方法:
This is my ConfigureServices method:
// This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services)
{
// Registers MongoDB conventions for ignoring default and blank fields
// NOTE: if you have registered default conventions elsewhere, probably don't need to do this
RegisterClassMap<ApplicationUser, IdentityRole, string>.Init();
// Add Mongo Identity services to the services container.
services.AddIdentity<ApplicationUser, IdentityRole>()
.AddMongoDBIdentityStores<ApplicationDbContext, ApplicationUser, IdentityRole, string>(options =>
{
options.ConnectionString = Configuration["Data:DefaultConnection:ConnectionString"]; // No default, must be configured if using (eg "mongodb://localhost:27017")
// options.Client = [IMongoClient]; // Defaults to: uses either Client attached to [Database] (if supplied), otherwise it creates a new client using [ConnectionString]
// options.DatabaseName = [string]; // Defaults to: "AspNetIdentity"
// options.Database = [IMongoDatabase]; // Defaults to: Creating Database using [DatabaseName] and [Client]
// options.UserCollectionName = [string]; // Defaults to: "AspNetUsers"
// options.RoleCollectionName = [string]; // Defaults to: "AspNetRoles"
// options.UserCollection = [IMongoCollection<TUser>]; // Defaults to: Creating user collection in [Database] using [UserCollectionName] and [CollectionSettings]
// options.RoleCollection = [IMongoCollection<TRole>]; // Defaults to: Creating user collection in [Database] using [RoleCollectionName] and [CollectionSettings]
// options.CollectionSettings = [MongoCollectionSettings]; // Defaults to: { WriteConcern = WriteConcern.WMajority } => Used when creating default [UserCollection] and [RoleCollection]
// options.EnsureCollectionIndexes = [bool]; // Defaults to: false => Used to ensure the User and Role collections have been created in MongoDB and indexes assigned. Only runs on first calls to user and role collections.
// options.CreateCollectionOptions = [CreateCollectionOptions]; // Defaults to: { AutoIndexId = true } => Used when [EnsureCollectionIndexes] is true and User or Role collections need to be created.
// options.CreateIndexOptions = [CreateIndexOptions]; // Defaults to: { Background = true, Sparse = true } => Used when [EnsureCollectionIndexes] is true and any indexes need to be created.
})
.AddDefaultTokenProviders();
services.AddIdentity<ApplicationRole, IdentityRole>()
.AddMongoDBIdentityStores<ApplicationDbContext, ApplicationUser, IdentityRole, string>(options =>
{
options.ConnectionString = Configuration["Data:DefaultConnection:ConnectionString"]; // No default, must be configured if using (eg "mongodb://localhost:27017")
// options.Client = [IMongoClient]; // Defaults to: uses either Client attached to [Database] (if supplied), otherwise it creates a new client using [ConnectionString]
// options.DatabaseName = [string]; // Defaults to: "AspNetIdentity"
// options.Database = [IMongoDatabase]; // Defaults to: Creating Database using [DatabaseName] and [Client]
// options.UserCollectionName = [string]; // Defaults to: "AspNetUsers"
// options.RoleCollectionName = [string]; // Defaults to: "AspNetRoles"
// options.UserCollection = [IMongoCollection<TUser>]; // Defaults to: Creating user collection in [Database] using [UserCollectionName] and [CollectionSettings]
// options.RoleCollection = [IMongoCollection<TRole>]; // Defaults to: Creating user collection in [Database] using [RoleCollectionName] and [CollectionSettings]
// options.CollectionSettings = [MongoCollectionSettings]; // Defaults to: { WriteConcern = WriteConcern.WMajority } => Used when creating default [UserCollection] and [RoleCollection]
// options.EnsureCollectionIndexes = [bool]; // Defaults to: false => Used to ensure the User and Role collections have been created in MongoDB and indexes assigned. Only runs on first calls to user and role collections.
// options.CreateCollectionOptions = [CreateCollectionOptions]; // Defaults to: { AutoIndexId = true } => Used when [EnsureCollectionIndexes] is true and User or Role collections need to be created.
// options.CreateIndexOptions = [CreateIndexOptions]; // Defaults to: { Background = true, Sparse = true } => Used when [EnsureCollectionIndexes] is true and any indexes need to be created.
})
.AddDefaultTokenProviders();
// Add MVC services to the services container.
services.AddMvc();
// Add application services.
services.AddTransient<IEmailSender, AuthMessageSender>();
services.AddTransient<ISmsSender, AuthMessageSender>();
}
这是我的AccountController类:
This is my AccountController class:
public class AccountController : Controller
{
private readonly UserManager<ApplicationUser> _userManager;
private readonly RoleManager<ApplicationRole> _roleManager;
private readonly SignInManager<ApplicationUser> _signInManager;
private readonly IEmailSender _emailSender;
private readonly ISmsSender _smsSender;
private readonly ILogger _logger;
public AccountController(
UserManager<ApplicationUser> userManager,
RoleManager<ApplicationRole> roleManager,
SignInManager<ApplicationUser> signInManager,
IEmailSender emailSender,
ISmsSender smsSender,
ILoggerFactory loggerFactory)
{
_userManager = userManager;
_roleManager = roleManager;
_signInManager = signInManager;
_emailSender = emailSender;
_smsSender = smsSender;
_logger = loggerFactory.CreateLogger<AccountController>();
}
}
添加了我的ApplicationRole类:
public class ApplicationUser : IdentityUser
{
}
public class ApplicationDbContext : IdentityDatabaseContext<ApplicationUser, ApplicationRole, string>
{
}
public class ApplicationRole : IdentityRole
{
}
任何想法如何注入?谢谢！
Any ideas how to inject this? Thanks!!
推荐答案
您在调用services.AddIdentity<ApplicationUser, IdentityRole>()时指定的是IdentityRole而不是ApplicationRole，这会注册RoleManager<IdentityRole>，但不会注册您的帐户控制者RoleManager<ApplicationRole>使用.
You're specifying IdentityRole instead of ApplicationRole when calling services.AddIdentity<ApplicationUser, IdentityRole>(), which registers RoleManager<IdentityRole> but not the RoleManager<ApplicationRole> your account controller is using.
在您的ConfigureServices方法中用ApplicationRole替换IdentityRole，它应该可以工作:
Replace IdentityRole by ApplicationRole in your ConfigureServices method and it should work:
services.AddIdentity<ApplicationUser, ApplicationRole>()
.AddMongoDBIdentityStores<ApplicationDbContext, ApplicationUser, ApplicationRole, string>();
