使用GET的ASP.Net MVC模型绑定复杂对象

I have a class in my web project:

我的网络项目中有一个课程：

public class MyClass
{
    public int? Param1 { get; set; }
    public int? Param2 { get; set; }
}

which is a parameter in my controller method:

这是我的控制器方法中的参数：

public ActionResult TheControllerMethod(MyClass myParam)
{
    //etc.
}

If I call the method using POST, the model binding works automatically (I use angular on the js side, which likely doesn't matter):

如果我使用POST调用方法，模型绑定会自动生效（我在js端使用angular，这可能无关紧要）：

$http({
    method: "post",
    url: controllerRoot + "TheControllerMethod",
    data: {   
        myParam: myParam
    }
}).success(function (data) {
    callback(data);
}).error(function () {
    alert("Error getting my stuff.");
});

If I use a GET, the parameter is always null in the controller.

如果我使用GET，则控制器中的参数始终为null。

$http({
    method: "get",
    url: controllerRoot + "TheControllerMethod",
    params: {   
        myParam: myParam
    }
}).success(function (data) {
    callback(data);
}).error(function () {
    alert("Error getting my stuff.");
});

Does complex model binding using the default model binder only work for POSTs, or is there something I can do to make this work with a GET?

使用默认模型绑定器的复杂模型绑定是否仅适用于POST，或者我可以做些什么来使其与GET一起工作？

The answer is Yes. The difference between GET and POST requests is that a POST body can have a content type so they can be interpreted correctly on the server side as XML, or Json, so on; for GET, all you have is just a querystring.

答案是肯定的。 GET和POST请求之间的区别在于POST主体可以具有内容类型，因此可以在服务器端将它们正确解释为XML或Json，依此类推;对于GET，你所拥有的只是一个查询字符串。

With ASP.NET MVC you can indeed bind your model on a GET request, as long as you have the same query string parameter names as of the property names of your Model class. Example from this answer:

使用ASP.NET MVC，您确实可以在GET请求上绑定模型，只要您具有与Model类的属性名称相同的查询字符串参数名称。这个答案的例子：

public class ViewModel
{
  public string Name { set;get;}
  public string Loc{ set;get;}
}

You can do a Get request like this

你可以这样做一个Get请求

MyAction?Name=jon&Loc=America

and MVC will automatically bind your model:

和MVC将自动绑定您的模型：

[HttpGet]
public ViewResult MyAction(ViewModel model)
{
    // Do stuff
    return View("ViewName", model);
}

Why are you calling the property "data" in the POST, and "params" in the GET? Both should be called "data".

你为什么要在POST中调用属性“data”，在GET中调用“params”？两者都应该被称为“数据”。

$http({
    method: "get",
    url: controllerRoot + "TheControllerMethod",
    data: {   
        myParam: myParam
    }
}).success(function (data) {
    callback(data);
}).error(function () {
    alert("Error getting my stuff.");
});
