I have a nuget package which contains an MVC controller - MyController which has a method MethodWithStringParameter(string a) and another method MethodWithoutParameters().
I have installed this nuget package in my MVC service and have registered the controller and the routes.

我有一个nuget包,其中包含一个MVC控制器 - MyController,它有一个方法MethodWithStringParameter(字符串a)和另一个方法MethodWithoutParameters()。我在我的MVC服务中安装了这个nuget包,并注册了控制器和路由。

public sealed class MyController : Controller
{
    [System.Web.Mvc.HttpPost]
    public HttpResponseMessage MethodWithStringParameter(string a)
    {
        return new HttpResponseMessage
        {
            StatusCode = HttpStatusCode.OK
        };
    }

    [System.Web.Mvc.HttpPost]
    public HttpResponseMessage MethodWithoutParameters()  
    {
        return new HttpResponseMessage
        {
            StatusCode = HttpStatusCode.OK
        };
    }
}

When I try hitting MethodWithStringParameter method, I get an exception

当我尝试点击MethodWithStringParameter方法时,我得到一个异常

Invalid JSON primitive: a.

无效的JSON原语:a。

However, I am able to hit the method MethodWithoutParameters without any issues.

但是,我能够毫无问题地使用方法MethodWithoutParameters。

Detailed exception

Type: "System.ArgumentException"

Message: "Invalid JSON primitive: a."
