OData元数据公开所有实体。净核心

odata .net-core asp.net-core c#

johnny 5 · 技术社区 · 6 年前

我试图将Odata配置为仅公开上下文中的某些实体。我正在使用。净核心。使用7.0.0 Beta2。包裹

services.AddOData();

//...

app.UseMvc(routeBuilder =>
{
    routeBuilder.MapODataServiceRoute("odata", null, GetModel());
    routeBuilder.EnableDependencyInjection();
});

public static IEdmModel GetModel()
{
    var builder = new ODataConventionModelBuilder();
    var skillSet = builder.EntitySet<Skill>(nameof(Skill));
    skillSet.EntityType.Count().Filter().OrderBy().Expand().Select();
    builder.ContainerName = "DefaultContainer";

    return builder.GetEdmModel();
}

当我导航到$元数据页面时,我可以看到我公开的实体以及数据库上下文中的所有其他实体

<?xml version="1.0" encoding="utf-8"?>
<edmx:Edmx Version="4.0" xmlns:edmx="http://docs.oasis-open.org/odata/ns/edmx">
    <edmx:DataServices>
        <Schema Namespace="Entities.Models" xmlns="http://docs.oasis-open.org/odata/ns/edm">
            <EntityType Name="Skill">
                <Key>
                    <PropertyRef Name="Id" />
                </Key>
                <Property Name="Id" Type="Edm.Int32" Nullable="false" />
                <Property Name="Name" Type="Edm.String" />
                <NavigationProperty Name="RequestNegotiations" Type="Collection(Entities.Models.RequestNegotiation)" />
                <NavigationProperty Name="UserSkills" Type="Collection(Entities.Models.UserSkill)" />
            </EntityType>
            <EntityType Name="Conversation">
                <Key>
                    <PropertyRef Name="Id" />
                </Key>
                <Property Name="Id" Type="Edm.Int32" Nullable="false" />
                <Property Name="Created" Type="Edm.DateTimeOffset" Nullable="false" />
                <NavigationProperty Name="ConversationSubscriptions" Type="Collection(Entities.Models.ConversationSubscription)" />
                <NavigationProperty Name="Messages" Type="Collection(Entities.Models.Message)" />
                <NavigationProperty Name="ServiceRequests" Type="Collection(Entities.Models.ServiceRequest)" />
            </EntityType>

如何仅公开在启动中注册的实体?

原来这是因为我的导航属性。如果您公开导航属性,它将检查所有连接的导航属性

public static IEdmModel GetModel()
{
    var builder = new ODataConventionModelBuilder();
    var skillSet = builder.EntitySet<Skill>(nameof(Skill));
    skillSet.EntityType.Ignore(x => x.RequestNegotiations);
    skillSet.EntityType.Ignore(x => x.UserSkills);

    builder.ContainerName = "DefaultContainer";

    return builder.GetEdmModel();
}
