模型绑定和 GET 请求？

发布于 2024-07-16 20:40:51 字数 990 浏览 5 评论 0原文

html 表单中有大量模型绑定的示例，但我想知道是否可以，如果可以，如何对 ActionLinks/GET 请求使用模型绑定。

因此，鉴于以下模型

public class Lurl
{
  public string Str {get;set;}
  public char Chr {get;set;}
  public double Dbl {get;set;}
}

和以下路线（我不确定这是如何形成的；我呈现它是为了展示我希望 URL 如何呈现属性 Str、Chr 和 Dbl），

routes.MapRoute(
    "LurlRoute",
    "Main/Index/{str}/{chr}/{dbl}",
    new
    {
        controller = "Main",
        action = "Index",
        lurl = (Lurl)null
    }
);

我想使用它在我的控制器中采用这种方式

[AcceptVerbs(HttpVerbs.Get)]
public ActionResult Index(Lurl lurl)
{
  /* snip */
}

，在我的页面中采用这种方式（两种可能的选项；还有更多吗？）

<div class="links">
  <%Html.ActionLink("Link one", "Index", new { lurl = Model })%><br />
  <%Html.ActionLink("Link two", "Index", 
         new { str = Model.Str, chr = Model.Chr, dbl = Model.Dbl })%>
</div>

模型绑定基础设施可以这样做吗？如果是这样，需要对我的样品进行哪些操作才能使其正常工作？

There are tons of examples for model binding in html forms, but I'm wondering if its possible to, and if so how to, use model binding for ActionLinks/GET requests.

So, given the following model

public class Lurl
{
  public string Str {get;set;}
  public char Chr {get;set;}
  public double Dbl {get;set;}
}

and the following route (I'm not sure how this would be formed; I present it to show how I'd like the URL presents the properties Str, Chr and Dbl)

routes.MapRoute(
    "LurlRoute",
    "Main/Index/{str}/{chr}/{dbl}",
    new
    {
        controller = "Main",
        action = "Index",
        lurl = (Lurl)null
    }
);

I'd like to use it this way in my Controller

[AcceptVerbs(HttpVerbs.Get)]
public ActionResult Index(Lurl lurl)
{
  /* snip */
}

and this way in my page (two possible options; are there more?)

<div class="links">
  <%Html.ActionLink("Link one", "Index", new { lurl = Model })%><br />
  <%Html.ActionLink("Link two", "Index", 
         new { str = Model.Str, chr = Model.Chr, dbl = Model.Dbl })%>
</div>

Is this possible with the model binding infrastructure? And if so, what needs to be done to my samples to get them working?

我认为您必须选择类作为参数方法

[AcceptVerbs(HttpVerbs.Get)]
public ActionResult Index(Lurl lurl)
{
   /* snip */
}

或属性作为参数方法

[AcceptVerbs(HttpVerbs.Get)]
public ActionResult Index(string str, char chr, double dbl)
{
    /* snip */
}

...尽管在类作为参数方法中，您可以使用“UpdateModel”方法。您可以传入要使用该方法更新的参数白名单，以防您只想更新模型中的几个值。

另外，在您的 MapRoute 中，lurl 将映射到您的路线路径中的什么参数？我很确定那里一定存在一对一的相关性。

I think you'll have to pick either the class as a parameter approach

[AcceptVerbs(HttpVerbs.Get)]
public ActionResult Index(Lurl lurl)
{
   /* snip */
}

or the properties as parameters approach

[AcceptVerbs(HttpVerbs.Get)]
public ActionResult Index(string str, char chr, double dbl)
{
    /* snip */
}

...though in the class as a parameter approach, you can use the "UpdateModel" method. You can pass in a whitelist of parameters you want to update with that method just in case you only want to update a few values in your model.

Also, In your MapRoute, what parameter will lurl map to in your route path? I'm pretty sure there has to be a one to one correlation there.
