BindAttribute在ASP.Net MVC Core(2.0.8)中似乎不起作用 [英] BindAttribute doesn't seem to work in ASP.Net MVC Core (2.0.8)

问题描述

我正在尝试使用Bind属性在模型中仅包括特定属性.我知道我可以使用视图模型并仅指定所需的属性，但是我不能使用它，因为代码必须经过一些静态代码分析，如果没有Bind属性，该分析会触发错误，并且我可以不能更改该规则(不受我控制).

I'm trying to use the Bind attribute to include only specific properties in my model. I know I can use a view model and only specify the properties I need, but I can't use that because the code has to run through some static code analysis that triggers an error if the Bind attribute is not present, and I can't change that rule (it's not controlled by me).

这是我尝试过的.

型号:

[Bind("One")]
public class SomeModel 
{
    public int One { get; set; }
    public int Two { get; set; }
}

控制器方法:

[HttpPost("foo")]
[Consumes("application/json")]
public IActionResult Foo([FromBody] SomeModel model)
{
    return Json(model);
}

我在POST中发送的内容:

What I'm sending in POST:

{
    "One": 1,
    "Two": 2
}

我得到的答复:

{
    "One": 1,
    "Two": 2
}

我还尝试将[Bind]属性放在控制器方法参数的前面，但这不起作用.

I also tried putting the [Bind] attribute right before the controller method parameter, but it doesn't work.

所以，我遇到的问题是，即使我明确告诉我只希望将"One"绑定，"Two"仍然会被分配一个值.

So, the problem I'm having is that "Two" still gets assigned a value, even though I explicitly told that I only want "One" to be bound.

我做错什么了吗?

推荐答案

看来[Bind]不适用于JSON，因此，至少在我的用例中，没有办法解决此问题.

It seems [Bind] doesn't work for JSON, so there's no way around this, at least for my use case.
