从网页API返回JSON驼峰 [英] Return camelCased JSON from Web API

问题描述

我试图返回骆驼

这是一个ASP.Net的Web API 2控制器套管JSON。我创建了只是其中的ASP.Net MVC和Web API位一个新的Web应用程序。我劫持了Values​​Controller像这样：

 公共类Values​​Controller：ApiController
{
    公共类的事
    {
        公众诠释标识{搞定;组; }
        公共字符串名字{获得;组; }
        公共字符串ISBN {搞定;组; }
        公众的DateTime RELEASEDATE {搞定;组; }        公共字符串[] {标签获取;组; }
    }    //获取API /值
    公共IHttpActionResult获得（）
    {
        VAR的事情=新的东西
        {
            ID = 123，
            名字=布莱恩
            ISBN =ABC213
            RELEASEDATE = DateTime.Now，
            标签=新的字符串[] {A，B，C，D}
        };        返回JSON（事）;
    }
}
 

在IE中运行这个，我得到如下结果：

<$p$p><$c$c>{\"Id\":123,\"FirstName\":\"Brian\",\"ISBN\":\"ABC213\",\"ReleaseDate\":\"2014-10-20T16:26:33.6810554-04:00\",\"Tags\":[\"A\",\"B\",\"C\",\"D\"]}

随着<一个href=\"http://odeto$c$c.com/blogs/scott/archive/2013/03/25/asp-net-webapi-tip-3-camelcasing-json.aspx\">K.关于这个问题的斯科特·艾伦的帖子，我增加了以下在WebApiConfig.cs文件注册方法：

 公共静态无效的注册（HttpConfiguration配置）
    {
        //网页API的配置和服务
        VAR格式化= GlobalConfiguration.Configuration.Formatters;
        VAR jsonFormatter = formatters.JsonFormatter;
        VAR设置= jsonFormatter.SerializerSettings;
        settings.Formatting = Formatting.Indented;
        settings.ContractResolver =新CamelCasePropertyNamesContractResolver（）;        //网页API路线
        config.MapHttpAttributeRoutes（）;        config.Routes.MapHttpRoute（
            名称：DefaultApi
            routeTemplate：API / {}控制器/（编号），
            默认：新{ID = RouteParameter.Optional}
        ）;
    }
 

不过，我仍然得到同样的，capitilization在我的结果。有我丢失的东西？我已经尝试了一些其他的方法，但没有什么工作呢。

解决方案

看起来像的主要问题是，我使用JsonResult快捷JSON（）作用的结果方式：

 公共IHttpActionResult获取（[FromUri]串领域，[FromUri]用户名字符串）
{
    VAR AUTHINFO = BLL.GetAuthenticationInfo（域名，用户名）;
    返回JSON（AUTHINFO）;
}
 

这显然是有格式的结果的完全控制。如果我切换到返回的Htt presponseMessage那么它将按预期工作：

 公开的Htt presponseMessage获取（[FromUri]串领域，[FromUri]用户名字符串）
{
    VAR AUTHINFO = BLL.GetAuthenticationInfo（域名，用户名）;
    返回Request.CreateResponse（的HTTPStatus code.OK，AUTHINFO）;
}
 

我没有最终使用code块在WebApiConfig文件Omar.Alani建议（相对于很多更长code，我在我的OP）。但是，真正的罪魁祸首是JsonResult操作方法。我希望这可以帮助别人了。

I'm trying to return camel cased JSON from an ASP.Net Web API 2 controller. I created a new web application with just the ASP.Net MVC and Web API bits in it. I hijacked the ValuesController like so:

public class ValuesController : ApiController
{
    public class Thing
    {
        public int Id { get; set; }
        public string FirstName { get; set; }
        public string ISBN { get; set; }
        public DateTime ReleaseDate { get; set; }

        public string[] Tags { get; set; }
    }

    // GET api/values
    public IHttpActionResult Get()
    {
        var thing = new Thing
        {
            Id = 123,
            FirstName = "Brian",
            ISBN = "ABC213", 
            ReleaseDate = DateTime.Now,
            Tags = new string[] { "A", "B", "C", "D"}
        };

        return Json(thing);
    }
}

Running this in IE, I get the following results:

{"Id":123,"FirstName":"Brian","ISBN":"ABC213","ReleaseDate":"2014-10-20T16:26:33.6810554-04:00","Tags":["A","B","C","D"]}

Following K. Scott Allen's post on the subject, I added the following to the Register method in the WebApiConfig.cs file:

public static void Register(HttpConfiguration config)
    {
        // Web API configuration and services
        var formatters = GlobalConfiguration.Configuration.Formatters;
        var jsonFormatter = formatters.JsonFormatter;
        var settings = jsonFormatter.SerializerSettings;
        settings.Formatting = Formatting.Indented;
        settings.ContractResolver = new CamelCasePropertyNamesContractResolver();

        // Web API routes
        config.MapHttpAttributeRoutes();

        config.Routes.MapHttpRoute(
            name: "DefaultApi",
            routeTemplate: "api/{controller}/{id}",
            defaults: new { id = RouteParameter.Optional }
        );
    }

However, I still get the same, capitilization in my results. Is there something I'm missing? I've tried a few other approaches but nothing works yet.

解决方案

Looks like the main issue was that I was using the JsonResult shortcut Json() action result method:

public IHttpActionResult Get([FromUri] string domain, [FromUri] string username)
{
    var authInfo = BLL.GetAuthenticationInfo(domain, username);
    return Json(authInfo);
}

It apparently had full control of formatting the results. If I switch to returning HttpResponseMessage then it works as expected:

public HttpResponseMessage Get([FromUri] string domain, [FromUri] string username)
{
    var authInfo = BLL.GetAuthenticationInfo(domain, username);
    return Request.CreateResponse(HttpStatusCode.OK, authInfo);
}

I did end up using the block of code in the WebApiConfig file as Omar.Alani suggested (opposed to the much lengthier code I had in my OP). But the real culprit was the JsonResult action method. I hope this helps someone else out.
