我的问题是，我希望返回camelcases(而不是标准PascalCase) JSON数据通过ActionResults从ASP。NET MVC控制器方法，由JSON.NET序列化。
作为一个例子，考虑下面的c#类:
public class Person
{
public string FirstName { get; set; }
public string LastName { get; set; }
}
默认情况下，当从MVC控制器返回这个类的实例作为JSON时，它将以以下方式序列化:
{
"FirstName": "Joe",
"LastName": "Public"
}
我希望它被序列化(由JSON.NET)为:
{
"firstName": "Joe",
"lastName": "Public"
}
我怎么做呢?
当前回答
在我看来越简单越好!
你为什么不这样做呢?
public class CourseController : JsonController
{
public ActionResult ManageCoursesModel()
{
return JsonContent(<somedata>);
}
}
简单基类控制器
public class JsonController : BaseController
{
protected ContentResult JsonContent(Object data)
{
return new ContentResult
{
ContentType = "application/json",
Content = JsonConvert.SerializeObject(data, new JsonSerializerSettings {
ContractResolver = new CamelCasePropertyNamesContractResolver() }),
ContentEncoding = Encoding.UTF8
};
}
}
其他回答
我是这样做的:
public static class JsonExtension
{
public static string ToJson(this object value)
{
var settings = new JsonSerializerSettings
{
ContractResolver = new CamelCasePropertyNamesContractResolver(),
NullValueHandling = NullValueHandling.Ignore,
ReferenceLoopHandling = ReferenceLoopHandling.Serialize
};
return JsonConvert.SerializeObject(value, settings);
}
}
这是MVC核心中一个简单的扩展方法，它会给你项目中的每个对象ToJson()能力，在我看来，在一个MVC项目中，大多数对象应该有成为json的能力，当然这取决于:)
您必须在“Startup.cs”文件中设置设置
您还必须在JsonConvert的默认值中定义它，这是如果您以后想直接使用库来序列化对象。
public void ConfigureServices(IServiceCollection services)
{
services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_2)
.AddJsonOptions(options => {
options.SerializerSettings.NullValueHandling = NullValueHandling.Ignore;
options.SerializerSettings.ContractResolver = new CamelCasePropertyNamesContractResolver();
});
JsonConvert.DefaultSettings = () => new JsonSerializerSettings
{
NullValueHandling = NullValueHandling.Ignore,
ContractResolver = new CamelCasePropertyNamesContractResolver()
};
}
对于WebAPI，请查看这个链接: http://odetocode.com/blogs/scott/archive/2013/03/25/asp-net-webapi-tip-3-camelcasing-json.aspx
基本上，添加以下代码到你的Application_Start:
var formatters = GlobalConfiguration.Configuration.Formatters;
var jsonFormatter = formatters.JsonFormatter;
var settings = jsonFormatter.SerializerSettings;
settings.ContractResolver = new CamelCasePropertyNamesContractResolver();
如果你在。net core web api中返回ActionResult，或IHttpAction结果，那么你可以用Ok()方法包装你的模型，该方法将匹配你前端的情况并为你序列化它。不需要使用JsonConvert。：）
或者，简单地说:
JsonConvert.SerializeObject(
<YOUR OBJECT>,
new JsonSerializerSettings
{
ContractResolver = new CamelCasePropertyNamesContractResolver()
});
例如:
return new ContentResult
{
ContentType = "application/json",
Content = JsonConvert.SerializeObject(new { content = result, rows = dto }, new JsonSerializerSettings { ContractResolver = new CamelCasePropertyNamesContractResolver() }),
ContentEncoding = Encoding.UTF8
};
