Question

我需要创建一个REST Web服务。为此我遵循了本教程：http://www.odata.org/blog/how-to-use-web-api-odata-to-build-an-odata-v4-service-without-entity-framework/

一切都很好，我还添加了BasicAuth，就像手套一样。

现在，我的问题...... 这个web服务将与它的可能版本一起使用，因此我们决定实现一种版本系统。此外，我们希望客户端应用程序选择他们想要执行其操作的数据库。为此，我们认为拥有这种风格的URI会很好：

http://localhost/Connection/northwind/API/1/DataRow

这是我的代码。我以前只定义了DataRow实体。现在我还定义了实体API和Connection。

如何实现我想要的URI /端点？到目前为止，这是我的代码。

Answer 1

您可以使用带有属性路由的全局路径前缀配置API版本控制...您可以创建一个继承自virtualenv的类，如下所示

DefaultDirectRouteProvider

并将其添加到WebApiConfig.cs中，如下所示

public class CentralizedPrefixProvider : DefaultDirectRouteProvider { private readonly string _centralizedPrefix; public CentralizedPrefixProvider(string centralizedPrefix) { _centralizedPrefix = centralizedPrefix; } protected override string GetRoutePrefix(HttpControllerDescriptor controllerDescriptor) { var existingPrefix = base.GetRoutePrefix(controllerDescriptor); if (existingPrefix == null) return _centralizedPrefix; return string.Format("{0}/{1}", _centralizedPrefix, existingPrefix); } }

Answer 2

只是向你抛出一个离不开的想法：如何使用依赖注入来使用DI容器或容器定义的工厂接口来创建控制器使用的版本化API的实例？ / p>

public interface IApiVersion {
    //the public method signatures
}

public interface IApiVersionFactory {
    IApiVersion Create(int version);
}

将工厂注入控制器并调用正确版本化API的方法，你就可以了。
