c# - 如何在 JSON 响应 ASP.NET Core 中关闭或处理 camelCasing？

Question

我正在学习有关 ASP.NET Core/Web API/Angular 2 的 WintellectNOW 类(class)。我已经实现了 API 部分，但无论出于何种原因，返回的 JSON 的变量名称都被小写了。

返回的 JSON 格式如下...

[
 {"id":1,"name":"Bowler","color":"black","count":1},
 {"id":2,"name":"Fedora","color":"red","count":1},
 {"id":3,"name":"Baseball Cap","color":"blue","count":3}
]

我期待...

[
 {"Id":1,"Name":"Bowler","Color":"black","Count":1},
 {"Id":2,"Name":"Fedora","Color":"red","Count":1},
 {"Id":3,"Name":"Baseball Cap","Color":"blue","Count":3}
]

基于...的C#模型

namespace HatCollection.Models
{
    public class Hat
    {
        public int Id { get; set; }
        public string Name { get; set; }
        public string Color { get; set; }
        public int Count { get; set; }
    }
}

我什至用 [DataMember(Name = "Id")] 装饰属性只是为了确保它仍然没有关系。

偶有与 Controller 中的Action和实例变量有关...

private static readonly List<Hat> MyHats = new List<Hat>
{
    new Hat {Id = 1, Name = "Bowler", Color = "black", Count = 1 },
    new Hat {Id = 2, Name = "Fedora", Color = "red", Count = 1 },
    new Hat {Id = 3, Name = "Baseball Cap", Color = "blue", Count = 3 }
};

[HttpGet]
public IEnumerable<Hat> Get()
{
    return MyHats;
}

如何关闭 camelCase 功能，以便 ASP.NET Core 返回属性名称而不更改它们？

Answer 1

在 Asp.Net Core 3.0 中，有些事情发生了变化。对于 camelCase，不做任何开箱即用的事情。对于 PascalCase 或其他集合样式使用。

services.AddMvc(setupAction=> {
            setupAction.EnableEndpointRouting = false;
        }).AddJsonOptions(jsonOptions =>
        {
            jsonOptions.JsonSerializerOptions.PropertyNamingPolicy = null;
        })
        .SetCompatibilityVersion(CompatibilityVersion.Version_3_0);

在 Startup.cs ConfigureServices 部分
