我已经按照他的示例链接到源代码。当我创建我的控制器(应该与他的TripsController相同)返回数据时,浏览器没有解析为HTML,只显示了JSON格式。
如果我使用“return View”语句,程序将正常工作。
以下是Startup.cs文件的内容:

using System.Collections.Generic;
using AutoMapper;
using Microsoft.AspNetCore.Authorization;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Extensions.Logging;
using RnD.Models.Repository;
using RnD.Models.ViewModels;
namespace RnD.Controllers.Web
{
[Route("/machines")]
[Authorize]
public class MachineTypeController : Controller
{
private ILogger<MachineTypeController> _logger;
private IMachineTypeRepository _repository;
public MachineTypeController(IMachineTypeRepository repository, ILogger<MachineTypeController> logger)
{
_logger = logger;
_repository = repository;
}
[HttpGet("")]
public IActionResult Index()
{
try
{
var results = _repository.GetAllMachineTypes();
return Ok(Mapper.Map<IEnumerable<MachineTypeViewModel>>(results));
}
catch (Exception ex)
{
_logger.LogError($"Failed to get all Machine types: {ex}");
return BadRequest("Error Occurred");
}
}
}
}
