我正在嘗試進(jìn)行 API 調(diào)用；我啟動(dòng) Visual Studio 并在郵遞員中輸入：http://localhost:51266/api/country我在該方法上設(shè)置了斷點(diǎn)，但沒(méi)有任何反應(yīng)。我得到了 404 未找到。這是控制器：[Route("api/[controller]")][ApiController]public class CountryController : Controller{ private ICountryRepository countryRepository; public CountryController(ICountryRepository repository) { this.countryRepository = repository; } [HttpGet] public IActionResult GetCountries() { var countries = countryRepository.GetCountries().ToList(); return Ok(countries); }}我在這里做錯(cuò)了什么？我在 Startup 中有這個(gè)：public void ConfigureServices(IServiceCollection services){ services.AddMvc(); var connectionString = Configuration["connectionStrings:bookDbConnectionString"]; services.AddDbContext<BookDbContext>(c => c.UseSqlServer(connectionString)); services.AddScoped<ICountryRepository, CountryRepository>();}我現(xiàn)在有這樣的：[ApiController]public class CountryController : Controller{ private ICountryRepository countryRepository; public CountryController(ICountryRepository repository) { this.countryRepository = repository; } [HttpGet] [Route("api/[controller]")] public IActionResult GetCountries() { var countries = countryRepository.GetCountries().ToList(); return Ok(countries); }}和我的啟動(dòng)課程：public class Startup{ public static IConfiguration Configuration { get; set; } public Startup(IConfiguration configuration) { Configuration = configuration; }我收到這個(gè)警告：警告 MVC1005使用“UseMvc”使用端點(diǎn)路由時(shí)不支持配置 MVC。要繼續(xù)使用“UseMvc”，請(qǐng)?jiān)O(shè)置“MvcOptions.EnableEndpointRouting = false”在“配置服務(wù)”內(nèi)。 WebApplication2 D:\Mijn Documents\VisualStudio_2019\WebApplication2\WebApplication2\Startup.cs

解決方案是這樣的：
public void ConfigureServices(IServiceCollection services) {
services.AddMvc();
services.AddControllers(); //added this
var connectionString = Configuration["connectionStrings:bookDbConnectionString"];
services.AddDbContext<BookDbContext>(c => c.UseSqlServer(connectionString));
services.AddScoped<ICountryRepository, CountryRepository>();
}
public void Configure(IApplicationBuilder app, IWebHostEnvironment env, BookDbContext context) {
if (env.IsDevelopment()) {
app.UseDeveloperExceptionPage();
}
app.UseRouting(); //uncommented
app.UseAuthorization(); //added this
app.UseEndpoints(endpoints => { //added this
endpoints.MapControllers();
});
//removed the app.UseMvc(); line
}

結(jié)合不同的方法來(lái)實(shí)現(xiàn)這一目標(biāo)
[Route("api/country")]
[ApiController]
public class CountryController : Controller
{
private ICountryRepository countryRepository;
public CountryController(ICountryRepository repository)
{
this.countryRepository = repository;
}
[HttpGet]
public IActionResult GetCountries()
{
var countries = countryRepository.GetCountries().ToList();
return Ok(countries);
}
}
或者
[Route("api/[controller]")]
[ApiController]
public class CountryController : Controller
{
private ICountryRepository countryRepository;
public CountryController(ICountryRepository repository)
{
this.countryRepository = repository;
}
[HttpGet("")]
public IActionResult GetCountries()
{
var countries = countryRepository.GetCountries().ToList();
return Ok(countries);
}
}
我最喜歡這個(gè)，我認(rèn)為它是最直觀的
[Route("api")]
[ApiController]
public class CountryController : Controller
{
private ICountryRepository countryRepository;
public CountryController(ICountryRepository repository)
{
this.countryRepository = repository;
}
[HttpGet("country")]
public IActionResult GetCountries()
{
var countries = countryRepository.GetCountries().ToList();
return Ok(countries);
}
}
如果這些都不起作用，那是因?yàn)槟鷽](méi)有在 中的 方法中調(diào)用 app.UseMVcConfigureStartup.cs
小唯快跑啊

問(wèn)題是路線，必須繼續(xù)行動(dòng)
[HttpGet]
[Route("api/[controller]")]
public IActionResult GetCountries()
或者，您可以將路由保留在控制器上，然后將一個(gè)空路由添加到操作中：
[Route("")]
