如何中检索从HTTPPOST，字典或表单值？ [英] How to retreive form values from HTTPPOST, dictionary or?

问题描述

我有一个MVC控制器具有此操作方法：

I have an MVC controller that has this Action Method:

[HttpPost]
public ActionResult SubmitAction()
{
     // Get Post Params Here
 ... return something ...
}

的形式是一个非平凡形式用一个简单的文本框。

The form is a non-trivial form with a simple textbox.

问

我如何获得的参数值？

How I access the parameter values?

我不是从View发布，后由外部来了。我假设有我有机会获得键/值对的集合。

I am not posting from a View, the post is coming externally. I'm assuming there is a collection of key/value pairs I have access to.

我试过 Request.Params.Get（simpleTextBox）; ，但返回错误

推荐答案

您可以有你的控制器动作需要一个对象，它反映的形式输入名称，默认模式粘结剂将自动为您创建该对象：

You could have your controller action take an object which would reflect the form input names and the default model binder will automatically create this object for you:

[HttpPost]
public ActionResult SubmitAction(SomeModel model)
{
    var value1 = model.SimpleProp1;
    var value2 = model.SimpleProp2;
    var value3 = model.ComplexProp1.SimpleProp1;
    ...

    ... return something ...
}

另一个（显然丑陋）的方法是：

Another (obviously uglier) way is:

[HttpPost]
public ActionResult SubmitAction()
{
    var value1 = Request["SimpleProp1"];
    var value2 = Request["SimpleProp2"];
    var value3 = Request["ComplexProp1.SimpleProp1"];
    ...

    ... return something ...
}
