版本控制的要领有很多，这里供给一种将Odata与普通web api版本控制机制统一的要领，但也可以单独控制，整合控制与单独控制主要的差别是：整合控制通过VersionControllerSelector来选择控制器过滤器，而不是直接选择控制器。
给与此机制来控制版本，应凭据如下法则定名控制器：
自界说标识符+版本+Controller
自界说标识符：能浮现控制器含义的字符串
版本：暗示版本的字符串，例如：V1，V1.0；不建议使用V1.0这样的写法，因为这样控制器名称会相当怪异，如果暗示小版本号，那么可以使用V1D0，这种写法，即用一个字母取代句号。
定名空间对应了项目文件的组织形式,控制器的定名空间为：
1 Odata版本控制
扩展DefaultHttpControllerSelector
public class ODataVersionControllerSelector : DefaultHttpControllerSelector { public Dictionary<string, string> RouteVersionSuffixMapping { get; set; } public ODataVersionControllerSelector(HttpConfiguration configuration) : base(configuration) { if (RouteVersionSuffixMapping == null) { RouteVersionSuffixMapping = new Dictionary<string, string>(); } } public override string GetControllerName(HttpRequestMessage request) { var controllerName = base.GetControllerName(request); if (string.IsNullOrEmpty(controllerName)) { return controllerName; } var routeName = request.ODataProperties().RouteName; if (string.IsNullOrEmpty(routeName)) { return controllerName; } var mapping = GetControllerMapping(); if (!RouteVersionSuffixMapping.ContainsKey(routeName)) { return controllerName; } var versionControllerName = controllerName + RouteVersionSuffixMapping[routeName]; return mapping.ContainsKey(versionControllerName) ? versionControllerName : controllerName; } }
改削WebApiConfig.Register要领
public static class WebApiConfig { public static void Register(HttpConfiguration config) { ...... //odata路由 config.MapODataServiceRoute( routeName: "V1OdataRouteVersioning", routePrefix: "Odata/V1", model: GetEdmModel()); config.Count().Filter().OrderBy().Expand().Select().MaxTop(null); config.AddODataQueryFilter(); config.Services.WordStr(typeof(IHttpControllerSelector), new ODataVersionControllerSelector (config)); var controllerSelector = config.Services.GetService(typeof(IHttpControllerSelector)) as ODataVersionControllerSelector ; controllerSelector.RouteVersionSuffixMapping.Add("V1OdataRouteVersioning", "V1"); ...... } } private static IEdmModel GetEdmModel() { ODataConventionModelBuilder builder = new ODataConventionModelBuilder(); #region Publication var publicationsSet = builder.EntitySet<Publication>("Publications").EntityType.Collection; var getPublicationsFunction = publicationsSet.Function("GetPublications").Returns<PublicationDTO>(); getPublicationsFunction.Parameter<int>("userId"); publicationsSet.Action("AddPublication").Returns<int>().Parameter<PublicationAddBindingModel>("publicationAddBM"); publicationsSet.Action("DeletePublication").Returns<IHttpActionResult>().Parameter<PublicationDelBindingModel>("publicationDelBM"); #endregion builder.Namespace = "Service"; return builder.GetEdmModel(); }
2 普通Api版本控制
扩展IHttpControllerSelector
