Blazor 无法解析类型 'Swashbuckle.AspNetCore.Swagger.ISwaggerProvider' 的服务

Question

我在使用路由向控制器添加端点时遇到问题。有人能帮我吗？这是 Program.cs 的代码我收到此错误：

System.InvalidOperationException：尝试调用中间件 'Swashbuckle.AspNetCore.Swagger.SwaggerMiddleware' 时无法解析类型 'Swashbuckle.AspNetCore.Swagger.ISwaggerProvider' 的服务。在 Microsoft.AspNetCore.Builder.UseMiddlewareExtensions.GetService（IServiceProvider sp，类型类型，类型中间件）在 lambda_method1（闭包，对象，HttpContext，IServiceProvider）在 Microsoft.AspNetCore.Builder.UseMiddlewareExtensions.<>c__DisplayClass5_1.b__2（HttpContext 上下文）在 Microsoft.AspNetCore.Routing.EndpointRoutingMiddleware.Invoke（HttpContext httpContext）在 Microsoft.AspNetCore.Diagnostics.DeveloperExceptionPageMiddleware.Invoke（HttpContext 上下文）

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddDbContext<AppDbContext>(options =>
    options.UseSqlServer(builder.Configuration.GetConnectionString("DBConnection")));

//Link interfaces with classes
builder.Services.AddScoped<IDepartmentRepository, DepartmentRepository>();
builder.Services.AddScoped<IEmployeeRepository, EmployeeRepository>();

builder.Services.AddControllers();
// Learn more about configuring Swagger/OpenAPI at https://aka.ms/aspnetcore/swashbuckle
builder.Services.AddEndpointsApiExplorer();

var app = builder.Build();

// Configure the HTTP request pipeline.
if (app.Environment.IsDevelopment())
{
    app.UseSwagger();
    app.UseSwaggerUI();
}

app.UseHttpsRedirection();

app.UseAuthorization();

app.MapControllers();

app.Run();

这里是控制器的代码。

[Route("api/[controller]")]// for specifing the route where this controller is accessible
[ApiController] 
public class EmployeesController : ControllerBase
{
    private readonly IEmployeeRepository _employeeRepository;

    public EmployeesController(IEmployeeRepository employeeRepository)
    {
        _employeeRepository = employeeRepository;
    }

    [HttpGet]
    public async Task<IActionResult> GetEmployees()
    {
        try
        {
            return Ok(await _employeeRepository.GetEmployees());
        }catch(Exception ex)
        {
            return StatusCode(StatusCodes.Status500InternalServerError, "Error retrieving data from the database");
        }
        
    }

}

你不见了AddSwaggerGen()

builder.Services.AddEndpointsApiExplorer();
builder.Services.AddSwaggerGen();
