如何通过 Ajax 调用将 Dictionary<Guid，int> 传递给 ASP.NET Core MVC 操作？

Question

我有这个函数:

reloadCartComponent() {
$.ajax({
url: "Products/UpdateCart",
data: {
o: "Roman"//what type of object will be bound to Dictionary<Guid, int> on the controller's side
},
success: function (data) {
$("#summary").html(data);
}
})
}

控制器中的这个动作方法:

public IActionResult UpdateCart(Dictionary<Guid, int> quantityDictionary = null)
{
return ViewComponent(typeof(CartComponent), quantityDictionary);
}

方法正在被调用，但我不知道我应该在脚本端构建什么对象，这将被正确地转换为控制器端的Dictionary<Guid, int>。

figure out:

public IActionResult UpdateCart(Dictionary<Guid,int> productQuantitiyDictionary = null)
{
return ViewComponent(typeof(CartComponent), productQuantitiyDictionary);
}

reloadCartComponent() {
var dict = {};
dict["443597a5-9940-49a8-94d5-3c386e9e6fd1"] = 1;
dict["4b27e0b7-6617-4ba2-b8aa-94751b3d9a7a"] = 2;

$.ajax({
url: "Products/UpdateCart",
data: {
productQuantitiyDictionary : dict
},
success: function (data) {
$("#summary").html(data);
}
})
}
