使用Web Api Http Put时内部服务器错误500

Question

我正在为使用Picking Process的公司开发一个Webapp。

这个过程非常简单，我有一个带有一些信息的销售订单，我创建了一个包含一些信息的拣配清单（例如：项目数，总重量和销售订单ID）。

我总是得到这个错误

内部服务器错误

...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] ，错误更改为：

找不到方法

要么

方法不允许

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 Side - 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，以及相同的错误。

UPDATE

当我重建我的解决方案时，我得到一些像这样的行：

Files \\ Microsoft Visual Studio \\ 2017 \\ Community \\ MSBuild \\ 15.0 \\ Bin \\ Microsoft.Common.CurrentVersion.targets（1964,5）：警告MSB3270：正在构建的项目的处理器体系结构“MSIL”与之间存在不匹配处理器体系结构的参考“Interop.ICrmDS800”，“x86”。 这种不匹配可能会导致运行时故障。 请考虑通过Configuration Manager更改项目的目标处理器体系结构，以便在项目和引用之间调整处理器体系结构，或者依赖于具有与项目的目标处理器体系结构相匹配的处理器体系结构的引用

可能是问题？ Interop.dll是我在项目中包含的文件，用于使用外部程序获取有关销售订单的信息。

解

在“ListaPicking”模型中缺少[Key]注释，我正在传递一个带有默认值的DateTime变量...我只是改为例如DateTime.Today，现在它正在工作:)

Answer 1

您调用PutAsJsonAsync但是当它需要一个表示json的字符串时，您将传递非json字符串作为您的数据参数。

从文档：

将PUT请求作为异步操作发送到指定的Uri，并将给定值序列化为JSON。

为了使其工作，请调用PutAsync 。

Answer 2

你可以发送整个模型

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

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

    return response.IsSuccessStatusCode;        
}

并以同样的方式接受它，而不是解构和重构它。

[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);
}
