【问题描述】:
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,我创建了一个包含一些信息的拣货清单(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
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,错误变为:
找不到方法
或
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 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,并且出现相同的错误。

更新
当我重建我的解决方案时,我得到了一些这样的行:
文件\Microsoft Visual Studio\2017\Community\MSBuild\15.0\Bin\Microsoft.Common.CurrentVersion.targets(1964,5): 警告 MSB3270:处理器之间不匹配 正在构建的项目架构“MSIL”和处理器 参考“Interop.ICrmDS800”、“x86”的架构。这 不匹配可能会导致运行时失败。请考虑更改 您的项目的目标处理器架构通过 配置管理器以调整处理器架构 在您的项目和参考之间,或依赖于 具有与目标相匹配的处理器架构的参考 您项目的处理器架构
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,并且我正在传递具有默认值的 DateTime 变量...我只是更改为例如 DateTime.Today,现在它正在工作:)
【问题讨论】:
-
在尝试访问它的成员之前检查 result.Length。此外,如果您调试代码并将服务器端的异常添加到问题中会更好。
