Question

我的api有一个返回多种响应类型的方法： GetTokenResponse ， ErrorsResponse ， ErrorResponse 。

[HttpPost("token")]
[ProducesResponseType(typeof(GetTokenResponse), (int)HttpStatusCode.OK)]
[ProducesResponseType(typeof(ErrorsResponse), (int)HttpStatusCode.BadRequest)]
[ProducesResponseType(typeof(ErrorResponse), (int)HttpStatusCode.Forbidden)]
public async Task<IActionResult> GetToken([FromBody] GetTokenRequest request)
{
    try
    {
        var token = await _authService.LoginAsync(request.Email, request.Password);
        return Ok(new GetTokenResponse { Token = token });
    }
    catch (Exception ex) when (ex is UserNotFoundException || ex is InvalidPasswordException)
    {
        return BadRequest(new ErrorsResponse("Invalid username or password."));
    }
    catch (EmailNotConfirmedException ex)
    {
        return StatusCode((int)HttpStatusCode.Forbidden, new ErrorResponse(ex.Message));
    }
}

并且客户端服务具有发出请求的方法

public async Task<bool> LoginAsync(GetTokenRequest request)
{
    var response = await _client.PostAsJsonAsync($"{_apiUrl}{Requests.Token}", request);

    if (response.StatusCode != HttpStatusCode.OK)
    {
        return false;
    }

    var responseString = await response.Content.ReadAsStringAsync();
    var result = JsonConvert.DeserializeObject<GetTokenResponse>(responseString);
    await Authenticate(result.Token, request.Email);

    return true;
}

在当前的实现方法中，可以返回true或false，仅处理 GetTokenResponse ，但我想处理所有响应类型。其实这就是问题。最好的方法是什么？我考虑过要从服务中返回响应内容并在调用者端解析响应类型，为响应创建一个基本响应类型\包装器，但是最佳实践怎么说？

我添加了扩展方法sureSuccess（）抛出异常

public async Task LoginAsync(GetTokenRequest request)
{
    var response = await _client.PostAsJsonAsync($"{_apiUrl}{Requests.Token}", request);
    var result = await response.EnsureSuccess<GetTokenResponse>();

    await Authenticate(result.Token, request.Email);
}

然后在页面上

public async Task ExecuteLogin()
{
    try
    {
        await AuthService.LoginAsync(_request);
        NavigationManager.NavigateTo("/");
    }
    catch (BadRequestException ex)
    {
        var response = ex.Response.Deserialize<ErrorsResponse>();
        Errors = response.Result.Messages;
    }
    catch (ForbiddenException ex)
    {
        var response = ex.Response.Deserialize<ErrorResponse>();
        Errors = new List<string> { response.Result.Message };
    }
}
