Asp.net web api ASP.NET核心中的IHttpActionResult和helper方法

我正在尝试将我的web api 2项目移动到ASP.NET 5。 但我有很多元素不再存在了

[Produces("application/json")]
[HttpPost]
public ActionResult GetSomeTable([FromBody] GridState state)
{
  return Ok(new
  {
    data = query.ToList(),
    paging = new
      {
        Total = total,
        Limit = state.limit,
        page = state.page,
        Returned = query.Count()
      }
  });
}

例如

IHttpActionResult

或

Ok（），NotFound（）

方法。 或

RoutePrefix

[]

[Produces("application/json")]
[HttpPost]
public ActionResult GetSomeTable([FromBody] GridState state)
{
  return Ok(new
  {
    data = query.ToList(),
    paging = new
      {
        Total = total,
        Limit = state.limit,
        page = state.page,
        Returned = query.Count()
      }
  });
}

我是否应该用

IActionResult

更改每个

IHttpActionResult

？ 用

新的ObjectResult

更改

Ok

（）？（是一样的吗？）

[Produces("application/json")]
[HttpPost]
public ActionResult GetSomeTable([FromBody] GridState state)
{
  return Ok(new
  {
    data = query.ToList(),
    paging = new
      {
        Total = total,
        Limit = state.limit,
        page = state.page,
        Returned = query.Count()
      }
  });
}

---

那startup.cs中似乎不再存在的

HttpConfiguration

呢？

IHttpActionResult

现在有效地

IActionResult

，要使用返回对象返回

Ok

，可以使用

返回新的ObjectResult（…）

[Produces("application/json")]
[HttpPost]
public ActionResult GetSomeTable([FromBody] GridState state)
{
  return Ok(new
  {
    data = query.ToList(),
    paging = new
      {
        Total = total,
        Limit = state.limit,
        page = state.page,
        Returned = query.Count()
      }
  });
}

所以实际上是这样的：

public IActionResult Get(int id)
{
    if (id == 1) return HttpNotFound("not found!");
    return new ObjectResult("value: " + id);
}

[Produces("application/json")]
[HttpPost]
public ActionResult GetSomeTable([FromBody] GridState state)
{
  return Ok(new
  {
    data = query.ToList(),
    paging = new
      {
        Total = total,
        Limit = state.limit,
        page = state.page,
        Returned = query.Count()
      }
  });
}

下面是一篇更详细的好文章：

[Produces("application/json")]
[HttpPost]
public ActionResult GetSomeTable([FromBody] GridState state)
{
  return Ok(new
  {
    data = query.ToList(),
    paging = new
      {
        Total = total,
        Limit = state.limit,
        page = state.page,
        Returned = query.Count()
      }
  });
}

更新的回复信息

[Produces("application/json")]
[HttpPost]
public ActionResult GetSomeTable([FromBody] GridState state)
{
  return Ok(new
  {
    data = query.ToList(),
    paging = new
      {
        Total = total,
        Limit = state.limit,
        page = state.page,
        Returned = query.Count()
      }
  });
}

我看到有人在评论中引用了
WebApiCompatShim

[Produces("application/json")]
[HttpPost]
public ActionResult GetSomeTable([FromBody] GridState state)
{
  return Ok(new
  {
    data = query.ToList(),
    paging = new
      {
        Total = total,
        Limit = state.limit,
        page = state.page,
        Returned = query.Count()
      }
  });
}

WebApiCompatShim
仍然是为这种可移植性场景维护的，现在发布了1.1.0版

[Produces("application/json")]
[HttpPost]
public ActionResult GetSomeTable([FromBody] GridState state)
{
  return Ok(new
  {
    data = query.ToList(),
    paging = new
      {
        Total = total,
        Limit = state.limit,
        page = state.page,
        Returned = query.Count()
      }
  });
}

我看到
Microsoft.AspNetCore.OData 1.0.0-rtm-00011
将
WebApiCompatShim
作为依赖项。我不知道他们在这方面到底想做什么，这些只是事实

[Produces("application/json")]
[HttpPost]
public ActionResult GetSomeTable([FromBody] GridState state)
{
  return Ok(new
  {
    data = query.ToList(),
    paging = new
      {
        Total = total,
        Limit = state.limit,
        page = state.page,
        Returned = query.Count()
      }
  });
}

如果您不想获得另一个兼容性软件包，并且希望进行更多的重构工作，那么可以采用以下方法：

[Produces("application/json")]
[HttpPost]
public ActionResult GetSomeTable([FromBody] GridState state)
{
  return Ok(new
  {
    data = query.ToList(),
    paging = new
      {
        Total = total,
        Limit = state.limit,
        page = state.page,
        Returned = query.Count()
      }
  });
}

您仍然可以使用
Ok（）
，或者在删除Http word时尝试使用
OkObjectResult（）
方法，以免过于冗长
HttpOkObjectResult
->
OkObjectResult

[HttpPost]
public ObjectResult Post([FromBody]string value)
{
    var item = new {Name= "test", id=1};
    return new OkObjectResult(item);
}


[HttpPost]
public ObjectResult Post([FromBody]string value)
{
    var item = new {Name= "test", id=1};
    return Ok(item);
}

[Produces("application/json")]
[HttpPost]
public ActionResult GetSomeTable([FromBody] GridState state)
{
  return Ok(new
  {
    data = query.ToList(),
    paging = new
      {
        Total = total,
        Limit = state.limit,
        page = state.page,
        Returned = query.Count()
      }
  });
}

在2.2版中，ASP.NET核心迁移指南规定将IHttpActionResult替换为ActionResult。这对我很有用：

[Produces("application/json")]
[HttpPost]
public ActionResult GetSomeTable([FromBody] GridState state)
{
  return Ok(new
  {
    data = query.ToList(),
    paging = new
      {
        Total = total,
        Limit = state.limit,
        page = state.page,
        Returned = query.Count()
      }
  });
}

尽管MVC 6中有一个
webapicomatshem
包用于此类可移植性场景，但建议不要使用它，因此我建议使用新的MVC 6方式。关于HttpConfiguration，您看过新的
Startup.cs
的外观了吗？你能试着把它移到那里吗？MVC6的新方法。。。ok，但是ReturnOK（mydata）是否等同于返回新的ObjectResult（mydata）{StatusCode=200}？对于httpconfiguration，我将尝试执行其他操作。谢谢，您为
Ok
所做的一切似乎都很好（在这种情况下，您不需要显式设置状态代码……它应该默认为200）…您可以使用这些帮助器方法编写自己的基本控制器，这样您就不需要在多个控制器中更改它…他是否应该使用
返回Ok（“value”+id）
Ok（）
仍然存在，似乎是表示API 200 Ok响应的合理方式。@CesarD yes在最新版本中，它又回到了
NotFound
、
Ok
等。微软不能在线保存自己的文档，真是太遗憾了。该URL现在重定向到（an？）ASP.NET主页。
