如何隐藏在网页API 2，ODATA元 [英] how to hide metadata in web api 2, odata

问题描述

我在使用定义 MapODataServiceRoute ODATA路线我的 WebApiConfig 。

I have defined odata route using MapODataServiceRoute in my WebApiConfig.

config.Routes.MapODataServiceRoute("CompanyoOdata", "odata", GetImplicitEdm(config));

private static IEdmModel GetImplicitEdm(HttpConfiguration config)
    {
        ODataModelBuilder builder = new ODataConventionModelBuilder(config, true);
        builder.EntitySet<Company>("Company");
        builder.EntitySet<Photo>("Photos");
        builder.EntitySet<Country>("Country");
        return builder.GetEdmModel();
    }

数据服务工作得很好。但我要实现一些事情。

The data service works just fine. But I want to achieve few things.

我不希望因为我使用它在内部暴露我的元数据或协会，将不再需要元数据。我怎么能限制访问这些信息（如限制访问 http://www.sample.com/odata /＃元或 http://www.sample.com/odata/ $元）

I don't want to expose my metadata or associations because i'm using it internally and will not need metadata. How can I restrict access to these information (i.e restrict access to http://www.sample.com/odata/#metadata or http://www.sample.com/odata/$metadata)

其次，我想忽略得到序列化的一些属性。我发现这样做有两种方式。

secondly, I want to ignore some properties from getting serialized. I found two ways of doing this.

1. 使用数据契约和标记具有属性 [数据成员] 属性或 [IgnoreDataMember] 属性


2. 使用忽略的方法的EntitySet 构建模型时

1. Using data contracts and marking properties with [DataMember] attribute or [IgnoreDataMember] attribute
2. Using Ignore method on EntitySet when building the model

因为我使用的数据库第一种方式为实体框架，因此不能与装饰属性的实体，我不能用第一种方法。我想我可以做到这一点通过使用 MetaDataType ，但似乎它仅适用于 DataAnnotations 。

I can't use the first method as I'm using Database first approach for entity framework hence can't decorate the entity with attributes. I thought I can achieve this by using MetaDataType, but it seems it only works for DataAnnotations.

我成功地使用第二种方法，但你不能传递忽略方法不止一个属性。必须这样做是为了个人财产，我需要忽略，这是一个有点乏味。是否有另一种方式来做到这一点？

I used second method with success, but you can't pass more than one property in the ignore method. Has to do it to individual property that I need to ignore, which is a bit tedious. Is there another way to do this?

任何帮助真的AP preciated。

any help really appreciated.

推荐答案

如果要隐藏的元数据（/ $元数据）或服务文件（/），可从现有的路由公约取出的MetadataRoutingConvention，例如：

If want to hide metadata (/$metadata) or service document (/), can remove the the MetadataRoutingConvention from existing routing conventions, e.g.:

var defaultConventions = ODataRoutingConventions.CreateDefault();
var conventions = defaultConventions.Except(
    defaultConventions.OfType<MetadataRoutingConvention>());
var route = config.MapODataServiceRoute(
    "odata",
    "odata",
    model,
    pathHandler: new DefaultODataPathHandler(),
    routingConventions: conventions);

如果只公开每个类型的几个属性，可以使用<一个href=\"http://blogs.msdn.com/b/alexj/archive/2012/08/15/odata-support-in-asp-net-web-api.aspx\">ODataModelBuilder而不是ODataConventionModelBuilder。例如，有些<一个href=\"https://aspnetwebstack.$c$cplex.com/SourceControl/latest#OData/test/System.Web.OData.Test/OData/Builder/ODataModelBuilderTest.cs\">example:

If only expose a few properties per type, can use ODataModelBuilder instead of ODataConventionModelBuilder. E.g., some example:

ODataModelBuilder builder = new ODataModelBuilder();
EntityTypeConfiguration<Customer> customer = builder.EntitySet<Customer>("Customers").EntityType;
customer.HasKey(c => c.Id);
customer.Property(c => c.Name);
