网络API 2：如何返回JSON与驼峰格式属性名称，在对象及其子对象

问题描述

更新

感谢所有的答案。我是一个新的项目，它看起来像我终于得到了这条底线：它看起来像下面的code实际上要怪：

Thanks for all the answers. I am on a new project and it looks like I've finally got to the bottom of this: It looks like the following code was in fact to blame:

        public static HttpResponseMessage GetHttpSuccessResponse(object response, HttpStatusCode code = HttpStatusCode.OK)
        {
            return new HttpResponseMessage()
            {
                StatusCode = code,
                Content = response != null ? new JsonContent(response) : null
            };
        }

在其他地方...

elsewhere...

            public JsonContent(object obj)
            {
                var encoded = JsonConvert.SerializeObject(obj, Newtonsoft.Json.Formatting.None, new JsonSerializerSettings { NullValueHandling = NullValueHandling.Ignore } );
                _value = JObject.Parse(encoded);

                Headers.ContentType = new MediaTypeHeaderValue("application/json");
            }

我忽略了一个普普通通的JsonContent假设它的WebAPI，但没有。

I had overlooked the innocuous looking JsonContent assuming it was WebAPI but no.

这是使用的处处的......可我只是第一个说，跆拳道？或许这应该是他们为什么要这样做？

This is used everywhere... Can I just be the first to say, wtf? Or perhaps that should be "Why are they doing this?"

原题如下的

人们会以为这是一个简单的配置设置，但它躲避我太久了。

One would have thought this would be a simple config setting, but it's eluded me for too long now.

我已经看过了各种解决方案和答案：

I have looked at various solutions and answers:

似乎并不适用于最新的WebAPI的版本...

doesn't seem to apply to latest WebAPI version...

下面似乎并没有工作 - 属性名称仍PascalCased

The following doesn't seem to work - property names are still PascalCased.

    var json = GlobalConfiguration.Configuration.Formatters.JsonFormatter;

    json.UseDataContractJsonSerializer = true;
    json.SerializerSettings.NullValueHandling = Newtonsoft.Json.NullValueHandling.Ignore;

    json.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();

Mayank的答案在这里：CamelCase JSON的WebAPI子对象（嵌套对象，子对象）似乎是不令人满意的，但可行的答案，直到我意识到这些属性将不得不为我们使用的是被添加到产生code LINQ2SQL ...

Mayank's answer here: CamelCase JSON WebAPI Sub-Objects (Nested objects, child objects) seemed like an unsatisfactory but workable answer until I realised these attributes would have to be added to generated code as we are using linq2sql...

任何方式自动做到这一点？这种讨厌一直困扰了我很长一段时间了。

Any way to do this automatically? This 'nasty' has plagued me for a long time now.

推荐答案

全部放在一起你...

Putting it all together you get...

protected void Application_Start()
{
    HttpConfiguration config = GlobalConfiguration.Configuration;
    config.Formatters.JsonFormatter.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver()
    config.Formatters.JsonFormatter.UseDataContractJsonSerializer = false;
}
