当试图访问ASP的端点时，HTTP错误404.. NET核心Web API

Question

我已经创建了一个新的ASP。. NET核心Web API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，但程序控制似乎没有进入控制器类和服务类。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类在下面:

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:

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

你已经用

装饰了你的控制器

[Route("api/companies")]

但是在你的电话中没有包含"api"。

就叫

localhost:5000/api/companies
