无法在Web Api 2中的BadRequest上收到错误消息 [英] Can't get error message on BadRequest in Web Api 2

问题描述

我在Google上搜索了很多问题，没有运气，所以请尝试其他人是否可以帮助我.

I've googled a lot searching for an answer to my problem with no luck so, let's try if someone else can help me.

在进行一些验证之后，我有一个Web Api 2操作来注册用户.如果一切正常，它将返回序列化的用户，否则，将返回BadRequest响应中发送的错误消息.

I have a Web Api 2 action to register an user after doing some validations. If everything works, it return the serialized user and if don't, an error message sent within a BadRequest response.

另一方面，我有一个WPF客户端，它调用API进行响应.

At the other hand, I have a WPF client that calls the API for a response.

我的问题是我无法获取错误发送的原因，客户端仅收到错误请求错误消息.

My problem is that I can't get the reason sent by the error, the client just get the Bad Request error message.

这是代码的一部分:

• Web Api操作:

• Web Api Action:

public async Task<IHttpActionResult> AddUser(NewUserDTO {
    if (!ModelState.IsValid)
    {
        return BadRequest(ModelState);
    }
    if (!model.IdCliente.HasValue)
    {
        ModelState.AddModelError("", "No existe el cliente");
        return BadRequest(ModelState);
    }
    // do save stuff
    return Ok(TheModelFactory.Create(user));
}

客户端功能:

Client function:

public async Task<ApplicationUserDTO> AddUser(NewUserDTO dto) {
    using (var client = new HttpClient()) {
        client.BaseAddress = new Uri(_urlBase);
        client.DefaultRequestHeaders.Accept.Clear();
        client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
        client.DefaultRequestHeaders.Authorization = new AuthenticationHeaderValue("Bearer", Token);
        HttpContent content = new StringContent(JsonConvert.SerializeObject(dto));
        content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
        HttpResponseMessage responseMessage = await client.PostAsync("api/accounts/AddUser", content);
        if (responseMessage.IsSuccessStatusCode) {
            var responseJson = await responseMessage.Content.ReadAsStringAsync();
            user = JsonConvert.DeserializeObject<ApplicationUserDTO>(responseJson);
        }
        else
             MessageBox.Show(responseMessage.Content.ReadAsStringAsync().Result);
        return user;
    } 
}

任何人都可以帮忙吗?

• DTO:

• DTO:

[Serializable]
public class NewUserDTO {
public int? IdCliente { get; set; }
[Required]
public string UserName { get; set; }
[Required]
public string Email { get; set; }
public string Role { get; set; }
public string Password { get; set; } }

无论如何... dto已正确发送到api螺母，这是您要求的序列化dto:

Anyway... the dto is sent correctly to api nut, here's the serialized dto as you asked for:

"{\"IdCliente\":null,\"UserName\":\"Toni\",\"Email\":\"[e-mail]\",\"Role\":\"Filtra\",\"Password\":\"TONI\"}"

推荐答案

最后，我放弃了. 也许在web.config，mvc config，api config处的一些代码，过滤或任何与控制器相比干扰和发送不同响应的代码. 我在DTO中添加了状态代码和消息属性，并始终返回一个对象. 无论如何，感谢所有试图帮助我的人.

Finally, I gived up. Maybe some code at web.config, mvc config, api config, filtering or whatever is disturbing and sending a diferent response than the controller does. I added a status code and a message property to my DTO and return always an object. Thanks anyway to all who tried to help me.
