使用 Web Api Http Put 时出现内部服务器错误 500

Question

我正在为一家使用 Picking Process 的公司开发 Webapp。

这个过程非常简单，我有一个包含一些信息的销售订单，我用其中的一些信息创建了一个领料单（例如：商品数量、总重量和销售订单的 ID）。

我总是遇到这个错误

Internal Server Error

...当我尝试使用 PUT 方法时，创建一个 Picking List 并将其添加到 Web Api 端的数据库中。

当我删除 [HttpPost] 时，错误更改为：

Method Not Found

或

Method Not Allowed

这是我的代码：

客户端

public async Task<bool> AddTarefa(ListasPicking listaPickingAdd) 
{
    String listaparaAdicionar = listaPickingAdd.idLista + ";" + listaPickingAdd.IDordemVenda + ";" + listaPickingAdd.peso + ";" + listaPickingAdd.itens;
    HttpResponseMessage response = await cliente.PutAsJsonAsync("api/ListasPicking/", listaparaAdicionar);

    return response.IsSuccessStatusCode;
}

Web Api 端 - 控制器

//PUT: api/ListasPicking
[ResponseType(typeof (ListasPicking))]
[HttpPut]
public  IHttpActionResult PutLista ([FromBody] String lista)
{
    if(!ModelState.IsValid)
    {
        return BadRequest(ModelState);
    }

    String[] result = lista.Split(';');
    ListasPicking novaLista = new ListasPicking();
    novaLista.idLista=result[0];
    novaLista.IDordemVenda = result[1];
    string lista_peso_converttoDouble = result[2];
    novaLista.peso = Convert.ToDouble(lista_peso_converttoDouble);
    string lista_items_converttoInt = result[3];
    novaLista.itens = Convert.ToInt32(lista_items_converttoInt);

    primContext.ListasPickingGet.Add(novaLista);
    primContext.SaveChanges();

    return StatusCode(HttpStatusCode.Created);
}

我尝试了一些与此类问题相关的解决方案，但出现了相同的错误。

更新

当我重建我的解决方案时，我得到了一些这样的行：

Files\Microsoft Visual Studio17\Community\MSBuild.0\Bin\Microsoft.Common.CurrentVersion.targets(1964,5): warning MSB3270: There was a mismatch between the processor architecture of the project being built "MSIL" and the processor architecture of the reference "Interop.ICrmDS800", "x86". This mismatch may cause runtime failures. Please consider changing the targeted processor architecture of your project through the Configuration Manager so as to align the processor architectures between your project and references, or take a dependency on references with a processor architecture that matches the targeted processor architecture of your project

会不会是问题？ Interop.dll 是我在我的项目中包含的一个文件，用于使用外部程序获取有关销售订单的信息。

解决方案

"ListaPicking" 模型中缺少 [Key] 注释，我正在传递一个具有默认值的 DateTime 变量...我只是更改为例如 DateTime.Today，现在它可以工作了:)

Answer 1

您调用了 PutAsJsonAsync，但当它需要表示 json 的字符串时，您传递了一个非 json 字符串作为您的数据参数。

来自文档：

Sends a PUT request as an asynchronous operation to the specified Uri with the given value serialized as JSON.

要使其正常工作，请改为调用 PutAsync。

Answer 2

您可以只发送整个模型

public async Task<bool> AddTarefa(ListasPicking listaPickingAdd) {

    var response = await cliente.PutAsJsonAsync("api/ListasPicking/", listaPickingAdd);

    return response.IsSuccessStatusCode;        
}

并在动作中以同样的方式接收它，而不是解构和重建它。

[ResponseType(typeof (ListasPicking))]
[HttpPut]
public  IHttpActionResult PutLista ([FromBody] ListasPicking novaLista) {
    if(!ModelState.IsValid) {
        return BadRequest(ModelState);
    }

    primContext.ListasPickingGet.Add(novaLista);
    primContext.SaveChanges();

    return StatusCode(HttpStatusCode.Created);
}
