客户端多重 api 响应处理

Question

我的 api 有一个 returns 多种响应类型的方法：GetTokenResponse、ErrorsResponse、错误响应.

[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));
    }
}

并且客户端服务有一个方法来发出请求

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 return true 或 false，仅处理 GetTokenResponse 但我想处理所有响应类型。其实就是这个问题。最好的方法是什么？ 我考虑过 return 从服务中获取响应内容并在调用方解析响应类型，为响应创建基本响应类型 \ 包装器，但最佳实践是怎么说的？

我添加了抛出异常的扩展方法 EnsureSuccess()

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 };
    }
}
