我试图像UserManager一样将RoleManager传递给我的控制器，但是我遇到了这个错误：
在处理请求时发生未处理的异常。
InvalidOperationException: 在尝试激活“Web.MongoDBIdentitySample.Controllers.AccountController”时无法解析类型为“Microsoft.AspNet.Identity.RoleManager`1 [Web.MongoDBIdentitySample.Models.ApplicationRole]”的服务。
这是我的ConfigureServices方法：
// 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：
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>();
}
}
编辑：增加了我的ApplicationRole类：
public class ApplicationUser : IdentityUser
{
}
public class ApplicationDbContext : IdentityDatabaseContext<ApplicationUser, ApplicationRole, string>
{
}
public class ApplicationRole : IdentityRole
{
}
有什么想法可以注入这个？谢谢！！
