当试图访问ASP.NET核心Web的端点时，HTTP错误404

Question

我创建了一个新的ASP.NET核心Web项目。但是当我在我的开发环境中运行它时，它给了我"HTTP Error 404. This localhost page can't be found.“。我尝试通过在Program.cs和ServiceExtension.cs类中放置几个调试点来调试应用程序，但是程序控件似乎没有进入Controller类和服务类。我的program.cs如下：

var builder = WebApplication.CreateBuilder(args);

// Including the path for configuration file for the NLog configuration.
LogManager.LoadConfiguration(string.Concat(Directory.GetCurrentDirectory(), "/nlog.config"));

// Add services to the container.
builder.Services.ConfigureCors();
builder.Services.ConfigureIISIntegration();
builder.Services.ConfigureLoggerService();
builder.Services.ConfigureSqlContext(builder.Configuration);
builder.Services.ConfigureRepositoryManager();
builder.Services.ConfigureServiceManager(); 
builder.Services.AddControllers().AddApplicationPart(typeof(CompanyEmployees.Presentation.AssemblyReference).Assembly);


var app = builder.Build();
if(app.Environment.IsDevelopment())
{
    app.UseDeveloperExceptionPage();
}
else
{
    app.UseHsts();
}
// Configure the HTTP request pipeline.

app.UseHttpsRedirection();
app.UseStaticFiles();
app.UseForwardedHeaders(new ForwardedHeadersOptions { ForwardedHeaders = ForwardedHeaders.All });
app.UseCors("CorsPolicy");
app.UseAuthorization();

app.MapControllers();

app.Run();

ServiceExtension.cs类如下所示：

namespace CompanyEmployees.Extensions
{
    public static class ServiceExtensions
    {
        public static void ConfigureCors(this IServiceCollection services) =>
        services.AddCors(options =>
        {
        options.AddPolicy("CorsPolicy", builder => builder.AllowAnyOrigin().AllowAnyMethod().AllowAnyHeader());
        });

        public static void ConfigureIISIntegration(this IServiceCollection services) =>
            services.Configure<IISOptions>(options =>
            {
                //We are not adding any options becasue we are configuring for default ones
            });

        public static void ConfigureLoggerService(this IServiceCollection services) => services.AddSingleton<ILoggerManager, LoggerManager>();

        public static void ConfigureRepositoryManager(this IServiceCollection services) => services.AddScoped<IRepositoryManager, RepositoryManager>();

        public static void ConfigureServiceManager(this IServiceCollection services) => services.AddScoped<IServiceManager, ServiceManager>();

        public static void ConfigureSqlContext(this IServiceCollection services, IConfiguration configuration) => services.AddDbContext<RepositoryContext>(opts => opts.UseSqlServer(configuration.GetConnectionString("sqlconnection")));
    } 
}

唯一的控制器类如下所示：

namespace CompanyEmployees.Presentation.Controllers
{
    [Route("api/companies")]
    [ApiController]
    public class CompaniesController : ControllerBase
    {
        private readonly IServiceManager _serviceManager;

        public CompaniesController(IServiceManager serviceManager)
        {
            _serviceManager = serviceManager;
        }

        [HttpGet]
        public IActionResult GetCompanies()
        {
            try
            {
                var companies = _serviceManager.CompanyService.GetAllCompanies(trackChanges: false);
                return Ok(companies);
            }
            catch
            {
                return StatusCode(500, "Internal Server Error");
            }
        }

    }
}

有人知道这里出了什么问题吗？或者如何有效地调试解决方案？

Answer 1

你用你的控制器装饰了

[Route("api/companies")]

但是在您的调用中，您没有包含"api“。

只管打电话

  localhost:5000/api/companies
