如何在Odata v6.0.0中启用，启用启用，启用并启用UnqualqualififififiedNamecall

Question

i最近将ODATA从（v5.9.1）更新为最新的稳定版本（v6.0.0），而在前一个我用来配置这样的环境的版本中：

        //Allows calling the Url like {entityAction}/{id}
        config.SetUrlConventions(ODataUrlConventions.KeyAsSegment);
        //Allows urls to be case insensitive
        config.EnableCaseInsensitive(true);
        // Remove the necessity of having to specify the namespace of enums.
        config.EnableEnumPrefixFree(true);
        //This allows call a function without using the full namespace.
        config.EnableUnqualifiedNameCall(true);
        config.MapODataServiceRoute("odata", "api/rest",
        edmModel, new  DefaultODataBatchHandler(GlobalConfiguration.DefaultServer));

现在更新后，如何获得与以前相同的结果？我的路线都不

The path template 'people/{parentId}/emails' on the action 'Get' in controller 'PersonEmails' is not a valid OData path template. The operation import overloads matching 'people' are invalid. This is most likely an error in the IEdmModel.

有什么想法吗？预先感谢。

我遇到了同样的问题。system.web.odata中有一个内部类，称为unqualifiedcallandenumprefixfreeresolver。从理论上讲，这将处理EnumpRefixFree和不合格的Namecall，但由于这是内部的，所以我现在必须写自己的。

public class UnqualifiedCallAndEnumPrefixFreeResolver : ODataUriResolver
{
    private readonly StringAsEnumResolver _stringAsEnum = new StringAsEnumResolver();
    private readonly UnqualifiedODataUriResolver _unqualified = new UnqualifiedODataUriResolver();
    private bool _enableCaseInsensitive;
    public override bool EnableCaseInsensitive
    {
        get { return this._enableCaseInsensitive; }
        set
        {
            this._enableCaseInsensitive = value;
            _stringAsEnum.EnableCaseInsensitive = this._enableCaseInsensitive;
            _unqualified.EnableCaseInsensitive = this._enableCaseInsensitive;
        }
    }
    #region UnqualifiedODataUriResolver
    public override IEnumerable<IEdmOperation> ResolveBoundOperations(IEdmModel model, string identifier,
        IEdmType bindingType)
    {
        return _unqualified.ResolveBoundOperations(model, identifier, bindingType);
    }
    public override IEnumerable<IEdmOperation> ResolveUnboundOperations(IEdmModel model, string identifier)
    {
        return _unqualified.ResolveUnboundOperations(model, identifier);
    }
    #endregion
    #region StringAsEnumResolver
    public override void PromoteBinaryOperandTypes(BinaryOperatorKind binaryOperatorKind,
        ref SingleValueNode leftNode, ref SingleValueNode rightNode, out IEdmTypeReference typeReference)
    {
        _stringAsEnum.PromoteBinaryOperandTypes(binaryOperatorKind, ref leftNode, ref rightNode, out typeReference);
    }
    public override IEnumerable<KeyValuePair<string, object>> ResolveKeys(IEdmEntityType type,
        IDictionary<string, string> namedValues, Func<IEdmTypeReference, string, object> convertFunc)
    {
        return _stringAsEnum.ResolveKeys(type, namedValues, convertFunc);
    }
    public override IEnumerable<KeyValuePair<string, object>> ResolveKeys(IEdmEntityType type,
        IList<string> positionalValues, Func<IEdmTypeReference, string, object> convertFunc)
    {
        return _stringAsEnum.ResolveKeys(type, positionalValues, convertFunc);
    }
    public override IDictionary<IEdmOperationParameter, SingleValueNode> ResolveOperationParameters(
        IEdmOperation operation, IDictionary<string, SingleValueNode> input)
    {
        return _stringAsEnum.ResolveOperationParameters(operation, input);
    }
    #endregion
}

用法将如下：

 configuration.MapODataServiceRoute(
            "ODataRoute",
            null,
            builder =>
                builder.AddService(ServiceLifetime.Singleton, sp => BuildModel())
                    .AddService<IEnumerable<IODataRoutingConvention>>(ServiceLifetime.Singleton, sp =>
                            ODataRoutingConventions.CreateDefaultWithAttributeRouting("ODataRoute", configuration))
                    .AddService<ODataUriResolver>(ServiceLifetime.Singleton, sp => new UnqualifiedCallAndEnumPrefixFreeResolver
                    {
                        EnableCaseInsensitive = true
                    })
        );          

我也将其发布在GitHub上，但目前尚无团队的答案，直到我们获得标准的东西，这是一个替代方案。
