在 blazor webassembly 中出现 "Inconsistent accessibility parameter type" 错误

Question

你好只是想得到一些澄清

我正在为 Blazor Web 程序集开发一个项目，我的 Api 控制器给出了以下错误消息。

Error CS0051 Inconsistent accessibility: parameter type 'IAuthRepository' is less accessible than method 'AuthController.AuthController(IAuthRepository)' BattlesBlazor.Server

这是我的服务响应class

using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace BattlesBlazor.Shared
{
    public class ServiceResponse<T>
    {
        public T Data { get; set; }
        public bool Success { get; set; }
        public string Message { get; set; }
    }
}

这是我的 IAuthRepository

using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace BattlesBlazor.Server.Data
{
    interface IAuthRepository
    {
        Task<ServiceResponse<int>> Register(User user, string password);
        Task<ServiceResponse<string>> Login(string email, string password);
        Task<bool> UserExists(string email);
    }
}

这是 AuthController

using BattlesBlazor.Shared;
using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;

namespace BattlesBlazor.Server.Controllers
{
    [Route("api/[controller]")]
    [ApiController]
  
    public class AuthController : ControllerBase
    {
        private readonly IAuthRepository _authRepo;

        public AuthController(IAuthRepository authRepo)
        {
            _authRepo = authRepo;
        }
    
        [HttpPost("register")]
        public async Task<IAuthRepository> Register(UserRegister request)
        {
            var response = await _authRepo.Register(
                new User {
                    Username = request.Username,
                    Email = request.Email,
                    Bananas = request.Bananas,
                    DateOfBirth =request.DateOfBirth,
                    IsConfirmed = request.IsConfirmed

                }, request.Password );

            if (!response.Success)
            {
                return BadRequest(response);
            }
            return Ok(response);
        }
    
    }

我尝试从“public class AuthController : ControllerBase”中删除“public”，这确实消除了错误，但是在 PostMan 上没有响应

如果有人能给我一些建议，我将不胜感激

Answer 1

此处代码中的 return 类型是问题所在：

[HttpPost("register")]
public async Task<IAuthRepository> Register(UserRegister request)

AuthController是public，Register也是，所以IAuthRepository也一定是public.

从您的定义中，我们可以看出 IAuthRepository 是默认值 (internal):

interface IAuthRepository
{
    Task<ServiceResponse<int>> Register(User user, string password);
    Task<ServiceResponse<string>> Login(string email, string password);
    Task<bool> UserExists(string email);
}

一般来说，解决办法就是让这些一致。那就是：你应该IAuthRepositorypublic（即public interface IAuthRepository）。另一方面，Register returns IAuthRepository 似乎很奇怪。不应该是returnServiceResponse<int>吗？:

[HttpPost("register")]
public async Task<ServiceResponse<int>> Register(UserRegister request)

Answer 2

将控制器方法的 return 类型更改为 Task<IActionResult>:

[HttpPost("register")]
public async Task<IActionResult> Register(UserRegister request)
...

或使 IAuthRepository public 并始终 return response。
