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，我有一份包含一些信息的销售订单，并且我创建了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）。

我总是遇到这个错误

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]时，错误更改为：

找不到方法

或

不允许的方法

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。

更新

当我重建我的解决方案时，我会得到一些这样的行：

Files \ Microsoft Visual 工作室\ 2017年\社区\的MSBuild \ 15.0 \斌\ Microsoft.Common.CurrentVersion.targets（1964,5）：警告MSB3270：处理器之间存在不匹配正在构建的项目架构“MSIL”和处理器参考“Interop.ICrmDS800”，“x86”的体系结构。这个不匹配可能导致运行时故障。请考虑改变通过的目标处理器架构的项目配置管理器，以便对齐处理器体系结构您的项目和引用之间，或依赖于具有与目标匹配的处理器体系结构的引用项目的处理器架构

可能是问题吗？ 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

“ListaPicking”模型中缺少[Key]注释，我正在使用默认值传递DateTime变量...我只是更改为例如DateTime.Today，现在它正在工作：）

Answer 1

你调用PutAsJsonAsync但是当你需要一个表示json的字符串时，你会传递一个非json字符串作为你的数据参数。

来自文档：

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。

要使其工作，请致电PutAsync。

Answer 2

您可以发送整个模型

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

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

    return response.IsSuccessStatusCode;        
}

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);
}

使用Web Api Http Put
