. NET Core-6 Web API，我有这个代码:
BaseController:
[Produces("application/json")]
[ApiController]
[ApiVersion("1.0")]
public class BaseApiController : ControllerBase
{
}
控制器:
[Consumes("application/json")]
public class AuthController : BaseApiController
{
private readonly ILogger<AuthController> _logger;
private IAuthService _authService;
public AuthController(ILogger<AuthController> logger, IAuthService authService)
{
_logger = logger;
_authService = authService;
}
[HttpPost]
[Route(ApiRoutes.Auth.SignIn)]
public async Task<ActionResult<Response<LoginResponseDto>>> Login([FromBody] LoginRequestDto model)
{
var result = await _authService.Login(model);
return StatusCode(result.StatusCode, result);
}
}
ApiRoutes:
public static class ApiRoutes
{
public const string Domain = "api";
public const string Version = "v{version:apiVersion}";
public const string Base = Domain + "/" + Version;
public static class Auth
{
public const string SignIn = Base + "/login";
}
}
IAuthService:
public interface IAuthService
{
Task<Response<LoginResponseDto>> Login(LoginRequestDto loginDto);
}
AuthService:
using Serilog;
public class AuthService : IAuthService
{
private readonly UserManager<ApplicationUser> _userManager;
private readonly IMapper _mapper;
private readonly ITokenGeneratorService _tokenGenerator;
private readonly IUnitOfWork _unitOfWork;
private readonly ILogger _logger;
private readonly ITokenRepository _tokenRepository;
public AuthService(UserManager<ApplicationUser> userManager, IUnitOfWork unitOfWork, ILogger logger,
IMapper mapper, ITokenGeneratorService tokenGenerator, ITokenRepository tokenRepository)
{
_userManager = userManager;
_mapper = mapper;
_tokenGenerator = tokenGenerator;
_unitOfWork = unitOfWork;
_logger = logger;
_tokenRepository = tokenRepository;
}
public async Task<Response<LoginResponseDto>> Login(LoginRequestDto model)
{
var response = new Response<LoginResponseDto>();
_logger.Information("Login Attempt");
var validityResult = await ValidateUser(model);
if (!validityResult.Successful)
{
_logger.Error("Login operation failed");
response.Message = validityResult.Message;
response.StatusCode = validityResult.StatusCode;
response.Successful = false;
return response;
}
//var user = await _userManager.FindByEmailAsync(model.Email);
var user = await _userManager.FindByEmailAsync(model.UserName);
var roles = await _userManager.GetRolesAsync(user);
var refreshToken = _tokenGenerator.GenerateRefreshToken();
user.RefreshToken = refreshToken;
user.RefreshTokenExpiryTime = DateTime.Now.AddDays(7); //sets refresh token for 7 days
var result = new LoginResponseDto()
{
Token = await _tokenGenerator.GenerateToken(user),
RefreshToken = refreshToken,
User = _mapper.Map<UserDto>(user),
Roles = roles,
//expires = token.ValidTo
};
await _userManager.UpdateAsync(user);
_logger.Information("User successfully logged in");
response.StatusCode = (int)HttpStatusCode.OK;
response.Message = "Login Successfully";
response.Data = result;
response.Successful = true;
return response;
}
}
ApplicationDbContext:
public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
public ApplicationDbContext(DbContextOptions<ApplicationDbContext> options) : base(options)
{
}
public DbSet<ApplicationUser> ApplicationUsers { get; set; }
public DbSet<ApplicationRole> ApplicationRoles { get; set; }
protected override void OnModelCreating(ModelBuilder builder)
{
builder.ApplyConfigurationsFromAssembly(typeof(ApplicationDbContext).Assembly);
base.OnModelCreating(builder);
}
}
抱歉，如果我的代码太多。我只是想展示全部细节。最后，在我的代码中，我有绑定服务的program.cs。
Program.cs:
var builder = WebApplication.CreateBuilder(args);
ConfigurationManager configuration = builder.Configuration;
var environment = builder.Environment;
var swaggerDocOptions = new SwaggerDocOptions();
// Add services to the container.
builder.Services.AddIdentity<ApplicationUser, ApplicationRole>(
options =>
{
options.SignIn.RequireConfirmedAccount = false;
options.User.RequireUniqueEmail = true;
options.Password.RequireUppercase = false;
}).AddEntityFrameworkStores<ApplicationDbContext>();
builder.Services.AddHttpContextAccessor();
builder.Services.AddMvc();
builder.Services.AddControllers().AddNewtonsoftJson(op => op.SerializerSettings.ReferenceLoopHandling
= Newtonsoft.Json.ReferenceLoopHandling.Ignore); ;
// AutoMapper
builder.Services.AddAutoMapper(AppDomain.CurrentDomain.GetAssemblies());
// Authentication
builder.Services.AddAuthentication(configuration);
// Db Injection
builder.Services.AddDbContextAndConfigurations(environment, configuration);
// Swagger
builder.Services.AddSwaggerGen();
builder.Services.AddOptions<SwaggerGenOptions>()
.Configure<IApiVersionDescriptionProvider>((swagger, service) =>
{
foreach (ApiVersionDescription description in service.ApiVersionDescriptions)
{
swagger.SwaggerDoc(description.GroupName, new OpenApiInfo
{
Title = swaggerDocOptions.Title,
Version = description.ApiVersion.ToString(),
Description = swaggerDocOptions.Description,
TermsOfService = new Uri("https://ddddd.com/LICENSE.md"),
Contact = new OpenApiContact
{
Name = swaggerDocOptions.Organization,
Email = swaggerDocOptions.Email
},
License = new OpenApiLicense
{
Name = "MIT",
Url = new Uri("https://ddddd.com")
}
});
}
var security = new Dictionary<string, IEnumerable<string>>
{
{"Bearer", new string[0]}
};
swagger.AddSecurityDefinition("Bearer", new OpenApiSecurityScheme
{
Description = "JWT Authorization header using the Bearer scheme.",
Name = "Authorization",
In = ParameterLocation.Header,
Type = SecuritySchemeType.ApiKey,
Scheme = "Bearer",
BearerFormat = "JWT"
});
swagger.OperationFilter<AuthorizeCheckOperationFilter>();
var xmlFile = $"{Assembly.GetExecutingAssembly().GetName().Name}.xml";
var xmlPath = Path.Combine(AppContext.BaseDirectory, xmlFile);
swagger.IncludeXmlComments(xmlPath);
});
// Register and Configure API versioning
builder.Services.AddApiVersioning(options =>
{
options.AssumeDefaultVersionWhenUnspecified = true;
options.DefaultApiVersion = new ApiVersion(1, 0);
options.ReportApiVersions = true;
});
// Register and configure API versioning explorer
builder.Services.AddVersionedApiExplorer(options =>
{
options.GroupNameFormat = "'v'VVV";
options.SubstituteApiVersionInUrl = true;
});
// DI
builder.Services.AddScoped<IAuthService, AuthService>();
builder.Services.AddScoped<IUnitOfWork, UnitOfWork>();
builder.Services.AddScoped<ITokenRepository, TokenRepository>();
builder.Services.AddScoped<ITokenGeneratorService, TokenGeneratorService>();
builder.Services.AddScoped<UserManager<ApplicationUser>>();
builder.Services.AddScoped<RoleManager<ApplicationRole>>();
builder.Logging.AddJsonConsole();
var app = builder.Build();
// Logging
ILogger logger = app.Logger;
// Seed At Start
using (var scope = app.Services.CreateScope())
{
var context = scope.ServiceProvider.GetRequiredService<ApplicationDbContext>();
var userManager = scope.ServiceProvider.GetRequiredService<UserManager<ApplicationUser>>();
var roleManager = scope.ServiceProvider.GetRequiredService<RoleManager<ApplicationRole>>();
try
{
await ApplicationSeeder.SeedData(context, userManager, roleManager);
}
catch (Exception ex)
{
logger.LogError(ex, "An error occured while attempting to create DB");
}
}
// Configure the HTTP request pipeline.
app.UseSwagger();
app.UseSwaggerUI();
app.UseHttpsRedirection();
app.UseAuthentication();
app.UseAuthorization();
app.UseHsts();
app.UseCors(x => x
.AllowAnyOrigin()
.AllowAnyMethod()
.AllowAnyHeader());
app.MapControllers();
string? port = Environment.GetEnvironmentVariable("PORT");
if (!string.IsNullOrWhiteSpace(port))
{
app.Urls.Add("http://*:" + port);
}
app.Run();
我使用了AutoMapper和Serilog。
当我尝试运行应用程序时，我得到了这个错误:
System.AggregateException
HResult=0x80131500
Message=Some services are not able to be constructed (Error while validating the service descriptor 'ServiceType: IAuthService Lifetime: Scoped ImplementationType: AuthService': Unable to resolve service for type 'Serilog.ILogger' while attempting to activate 'AuthService'.)

This exception was originally thrown at this call stack:
[External Code]
Inner Exception 1:
InvalidOperationException: Error while validating the service descriptor 'ServiceType: IAuthService Lifetime: Scoped ImplementationType: AuthService': Unable to resolve service for type 'Serilog.ILogger' while attempting to activate 'AuthService'.
Inner Exception 2:
InvalidOperationException: Unable to resolve service for type 'Serilog.ILogger' while attempting to activate 'AuthService'.
我把这个添加到Program.cs:
var logger = new LoggerConfiguration()
.ReadFrom.Configuration(builder.Configuration)
.Enrich.FromLogContext()
.CreateLogger();
builder.Logging.ClearProviders();
builder.Logging.AddSerilog(logger);
var app = builder.Build();
和这个到appsettings:
"Serilog": {
"Using": [ "Serilog.Sinks.Console", "Serilog.Sinks.File" ],
"MinimumLevel": {
"Default": "Information",
"Override": {
"Microsoft": "Warning",
"Microsoft.Hosting.Lifetime": "Information"
}
},
"Filter": [
{
"Name": "ByExcluding",
"Args": { "expression": "@mt = 'An unhandled exception has occurred while executing the request.'" }
}
],
"WriteTo": [
{
"Name": "File",
"Args": {
//"path": "./logs/log-.txt",
"path": "../logs/webapi-.log",
"rollingInterval": "Day",
"outputTemplate": "{Timestamp:yyyy-MM-dd HH:mm:ss.fff zzz} [{Level:u3}] {Username}{Message:lj}{NewLine}{Exception}"
}
},
{
"Name": "Seq",
"Args": { "serverUrl": "http://localhost:5341" }
}
]
},
但是错误仍然存在。
如何解决?
感谢无法解析类型为" Serilog "的服务。当试图激活'AuthService'时，ILogger'就是它的意思。您需要在IOC容器中注册iloglogger，请按照https://github.com/serilog/serilog-aspnetcore
上的详细步骤进行操作。
