AspNetCore 无法解析服务

Question

我正在将Microsoft.AspNetCore.Identity添加到项目中，我得到

InvalidOperationException：在尝试激活"Web.Security.Services.SecurityService"2[Web.Security.Entities.IUser'1[System.Int32]]时，无法解析类型"Microsoft.AspNetCore.Identity.SignInManager'1[Web.Security.Entities.SignInManager'1[Web.Security.Entities.1[System.Int32]]'的服务。

例外是从邮递员复制粘贴的，它编码了一些符号。 这是我的创业.cs：

public class Startup
{
ServiceProvider serviceProvider;
IConfigurationRoot configurationRoot;
public IConfiguration Configuration { get; }
public Startup(IConfiguration configuration)
{
Configuration = configuration;
configurationRoot = new ConfigurationBuilder()
.AddJsonFile("appsettings.json", optional: false)
.AddIniFile("3CXPhoneSystem.ini")
.Build();
}
// This method gets called by the runtime. Use this method to add services to the container.
// For more information on how to configure your application, visit https://go.microsoft.com/fwlink/?LinkID=398940
public void ConfigureServices(IServiceCollection services)
{
serviceProvider = services
.AddLogging((builder) => builder.SetMinimumLevel(LogLevel.Trace))            
.AddSingleton<ISecurityService, SecurityService<IUser<int>, int>>()
.AddSingleton<ITaskService, TaskService>()
.AddTransient<IEmailSender, EmailSender>()
.AddSingleton<ITranslation, Translation>()
.BuildServiceProvider();
services.AddDbContext<SecurityDbContext>(options =>
options.UseSqlServer(Configuration.GetConnectionString("dataContext")));
services.AddIdentity<Web.Security.Entities.User<int>, IdentityRole>()
.AddEntityFrameworkStores<SecurityDbContext>()
.AddDefaultTokenProviders();
services.AddCors(o => o.AddPolicy("CorsPolicy", builder =>
{
builder
.AllowAnyMethod()
.AllowAnyHeader()
.WithOrigins("http://localhost:52170");
}));
services.AddMvc();
services.Configure<IdentityOptions>(options =>
{
// Password settings
options.Password.RequireDigit = true;
options.Password.RequiredLength = 8;
options.Password.RequireNonAlphanumeric = false;
options.Password.RequireUppercase = true;
options.Password.RequireLowercase = false;
options.Password.RequiredUniqueChars = 6;
// Lockout settings
options.Lockout.DefaultLockoutTimeSpan = TimeSpan.FromMinutes(30);
options.Lockout.MaxFailedAccessAttempts = 10;
options.Lockout.AllowedForNewUsers = true;
// User settings
options.User.RequireUniqueEmail = true;
});

}

// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app.UseDefaultFiles();
app.UseStaticFiles();
app.Use(async (context, next) =>
{
await next();
if (context.Response.StatusCode == 404 && !Path.HasExtension(context.Request.Path.Value) && !context.Request.Path.Value.StartsWith("api"))
{
context.Response.Redirect("/");
}
});

app.UseMvc(routes =>
{
routes.MapRoute(name: "DefaultApi", template: "api/{controller}/{action}/{id?}");
routes.MapRoute("RouteToAngular", "{*url}", defaults: new { controller = "Route", action = "Index" });
});
app.UseAuthentication();
app.UseCors("CorsPolicy");
}

在这里，SecurityService是一个将处理注册/登录/其他身份相关请求的类，它看起来像这样

public class SecurityService<TUser, TKey> : ISecurityService where TUser : class, IUser<TKey>
{
SignInManager<TUser> signInManager;
IConfiguration configuration;
private readonly IHttpContextAccessor httpContextAccessor;
UserManager<TUser> userManager;
IEmailSender emailSender;
IUrlHelper urlHelper;
ISession session;
ILogger<SecurityService<TUser, TKey>> logger;
ITranslation translation; 
public SecurityService(
SignInManager<TUser> signInManager,
UserManager<TUser> userManager,
IConfiguration configuration,
IHttpContextAccessor httpContextAccessor,
IEmailSender emailSender,
IUrlHelper urlHelper,
ISession session,
ILogger<SecurityService<TUser, TKey>> logger,
ITranslation translation)
{
this.signInManager = signInManager;
this.userManager = userManager;
this.configuration = configuration;
this.httpContextAccessor = httpContextAccessor;
this.urlHelper = urlHelper;
this.session = session;
this.logger = logger;
this.translation = translation;
this.emailSender = emailSender;
}

IUser.cs：

public interface IUser<TKey>
{
TKey Id { get; set; }
string UserName { get; set; }
string Email { get; set; }
bool EmailConfirmed { get; set; }
}

您需要显式使用IdentityBuilder扩展方法AddSignInManager。

services.AddIdentity<Web.Security.Entities.User<int>, IdentityRole>()
.AddEntityFrameworkStores<SecurityDbContext>()
// Replace ApplicationUser with your concrete user class
.AddSignInManager<SignInManager<ApplicationUser>>() 
.AddDefaultTokenProviders();

如果您需要在安全服务中访问它，则可以注入它：

public class SecurityService<TUser, TKey> ...
{
public SecurityService(SignInManager<ApplicationUser> signInManager)
{
this.signInManager = signInManager;
}
}
