Я пытаюсь сделать так, чтобы мое ядро web api возвращало приложение / json, но, как ни странно, оно всегда возвращает эту html страницу, нарушающую соглашение об ошибках, установленное командой.
Вот код i ' я пытаюсь выполнить, но пока безуспешно:
Startup.cs
public class Startup
{
public Startup(IConfiguration configuration)
{
Configuration = configuration;
}
public IConfiguration Configuration { get; }
public void ConfigureServices(IServiceCollection services)
{
services.AddCors();
services.AddControllers().AddNewtonsoftJson(options =>
{
options.SerializerSettings.Converters.Add(new IsoDateTimeConverter { DateTimeFormat = "dd/MM/yyyy" });
});
services.AddMvcCore().AddRazorViewEngine().AddRazorRuntimeCompilation().ConfigureApiBehaviorOptions(options =>
{
options.InvalidModelStateResponseFactory = actionContext =>
{
var errorList = (from item in actionContext.ModelState
where item.Value.Errors.Any()
select item.Value.Errors[0].ErrorMessage).ToList();
return new BadRequestObjectResult(new
{
ErrorType = "bad_request",
HasError = true,
StatusCode = (int)HttpStatusCode.BadRequest,
Message = "Formato do request inválido",
Result = new
{
errors = errorList
}
});
};
});
}
// This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
if (env.IsDevelopment())
{
app.UseDeveloperExceptionPage();
}
app.UseMiddleware(typeof(ErrorHandlingMiddleware));
app.UseCors(
options => options.AllowAnyOrigin().SetIsOriginAllowed(x => _ = true).AllowAnyMethod().AllowAnyHeader()
);
app.UseHttpsRedirection();
app.UseRouting();
app.UseStaticFiles();
app.UseAuthentication();
app.UseAuthorization();
app.UseEndpoints(endpoints =>
{
endpoints.MapControllers();
});
}
}
AuthController.cs
[HttpPost("refreshtoken")]
public IActionResult PostRefreshToken(Guid token)
{
if (!_authTokenService.IsValid(token))
{
return NotFound(new JsonResponse
{
HasError = true,
ErrorType = "not_found",
StatusCode = (int)HttpStatusCode.NotFound,
Title = "Token não encontrado",
Message = "refresh is not valid because it was not found or does not comply",
});
}
var savedToken = _authTokenService.Get(token);
...
return Ok(new JsonResponse
{
StatusCode = (int)HttpStatusCode.OK,
Title = "Token atualizado",
Message = "jwt access token refreshed with success, please update your keys for subsequent requests",
Result = new
{
Expiration = accessToken.Expiration.ToString("dd/MM/yyyy HH:mm:ss"),
AccessToken = accessToken.Token,
RefreshToken = refreshToken.Token,
}
});
}
когда был выполнен этот код, я был ожидание результата json при достижении блока NotFound (), но вместо этого он возвращает этот текст / html page
