Simple.OData.Client - 无法调用接受实体集合参数的操作

Question

I get error "The parameter 'wheels' is of Edm type kind 'Collection'. You cannot call CreateCollectionWriter on a parameter that is not of Edm type kind 'Collection'."

以下是我的设置的详细信息：

Web API 2.2 OData v4 服务：我在我的服务中定义了 WheelsController class 中的操作，如下所示：

public async Task<IHttpActionResult> UpdateWheels(ODataActionParameters   parameters)
{
object value;
parameters.TryGetValue("carId", out value);
int carId= (int)value;
parameters.TryGetValue("wheels", out value)
IEnumerable<Wheel> wheels = (IEnumerable<Wheel>)value;
// logic goes here....
return OK();
}

在WebApiConfig.cs个文件中，Action配置定义如下：

ODataConventionModelBuilder builder = new ODataConventionModelBuilder();
builder.EntitySet<Car>("Cars");
builder.EntitySet<Wheel>("Wheels");
var action = builder.EntityType<Wheel>().Collection.Action("UpdateWheels");
action.Parameter<int>("carId");
action.CollectionParameter<Wheel>("wheels");

我成功地从 FireFox 浏览器中的 RESTClient 扩展调用上述操作 作为 POST 请求 URL“http://localhost/Service/Wheels/UpdateWheels”请求正文为

{"carId":2,
"wheels":[{"Id":1,"Name":"Wheel Front 1","Description":"Front wheel left",   "PositionEnum":"FrontLeft"},
{"Id":2,"Name":"Wheel Front 2","Description":"Front wheel right",   "PositionEnum":"FrontRight"}]
}

但是，当我尝试在

等客户端应用程序中使用 Simple.OData.Client 调用上述服务操作时，它会给出 error

public async void TestUpdateWheels(List<Wheel> wheelList)
{
// client is derived from ODataClient from assembly Simple.OData.Client.Core.dll, v4.3.0.0
await client.For<Wheel>()
.Action("UpdateWheels")
.Set(new { carId = 2, wheels = wheelList})
.ExecuteAsync();
}

Error message: The parameter 'wheels' is of Edm type kind 'Collection'. You cannot call CreateCollectionWriter on a parameter that is not of Edm type kind 'Collection'.

如何从 ODataClient 成功调用上述 Action？

Answer 1

这样试试。它适用于我的一个项目。

public async Task<string> TestUpdateWheels(List<Wheel> wheelList)
{
    string getRules = await client.ExecuteActionAsScalarAsync<string>
     ("UpdateWheels", new Dictionary<string, object>
        {
           { "YourParamater", wheelList}

        });
   return getRules ;
}

Answer 2

当我向项目网站报告时，这是 Simple.OData.Client 版本 4.3.0 中的一个错误。详情请访问linkhttps://github.com/object/Simple.OData.Client/issues/117

The new bug fix version 4.7.2 of Simple.OData.Client has fixed the issue for me!
