c# – MVC3 REST路由和Http动词

这是一个后续问题,我正在尝试学习这两种方法之间的事实差异/微妙之处.如果可能,我正在寻求权威的答案.

方法1：单路由,操作名称Http控制器动作的动态属性

>使用指定的动作参数在Global.asax中注册一条路线.

public override void RegisterArea(AreaRegistrationContext context)
{
    // actions should handle: GET,POST,PUT,DELETE
    context.MapRoute("Api-SinglePost","api/posts/{id}",new { controller = "Posts",action = "SinglePost" });
}

>将ActionName和HttpVerb属性应用于控制器操作

[HttpGet]
[ActionName("SinglePost")]
public JsonResult Get(string id)
{
    return Json(_service.Get(id));
}
[HttpDelete]
[ActionName("SinglePost")]
public JsonResult Delete(string id)
{
    return Json(_service.Delete(id));
}
[HttpPost]
[ActionName("SinglePost")]
public JsonResult Create(Post post)
{
    return Json(_service.Save(post));
}
[HttpPut]
[ActionName("SinglePost")]
public JsonResult Update(Post post)
{
    return Json(_service.Update(post););
}

方法2：唯一路由动词约束,控制器动作具有Http动词属性

>使用HttpMethodContraint在Global.asax中注册唯一的路由

var postsUrl = "api/posts";

routes.MapRoute("posts-get",postsUrl + "/{id}",action = "Get",new { httpMethod = new HttpMethodConstraint("GET") });

routes.MapRoute("posts-create",postsUrl,action = "Create",new { httpMethod = new HttpMethodConstraint("POST") });

routes.MapRoute("posts-update",action = "Update",new { httpMethod = new HttpMethodConstraint("PUT") });

routes.MapRoute("posts-delete",action = "Delete",new { httpMethod = new HttpMethodConstraint("DELETE") });

>在控制器操作上仅使用Http动词属性

[HttpGet]
public JsonResult Get(string id)
{
    return Json(_service.Get(id));
}
[HttpDelete]
public JsonResult Delete(string id)
{
    return Json(_service.Delete(id));
}
[HttpPost]
public JsonResult Create(Post post)
{
    return Json(_service.Save(post));
}
[HttpPut]
public JsonResult Update(Post post)
{
    return Json(_service.Update(post););
}

这两种方法都让我有独一无二的命名控制器操作方法,并允许与动词绑定的RESTful路由…但是限制路由与使用代理操作名称有什么不同？
