SignalR:使用骆驼套 [英] SignalR : use camel case

问题描述

我想知道是否有一种配置SignalR的方法，以便集线器中的客户端功能使用驼峰式大小写返回对象.

I would like to know if there is a way to configure SignalR so that the client functions in the hub return objects using camel case.

谢谢.

推荐答案

滚动您自己的Conttract解析器

Roll your own Conttract resolver like

public class SignalRContractResolver : IContractResolver
{

    private readonly Assembly assembly;
    private readonly IContractResolver camelCaseContractResolver;
    private readonly IContractResolver defaultContractSerializer;

    public SignalRContractResolver()
    {
        defaultContractSerializer = new DefaultContractResolver();
        camelCaseContractResolver = new CamelCasePropertyNamesContractResolver();
        assembly = typeof(Connection).Assembly;
    }

    public JsonContract ResolveContract(Type type)
    {
        if (type.Assembly.Equals(assembly))
        {
            return defaultContractSerializer.ResolveContract(type);

        }

        return camelCaseContractResolver.ResolveContract(type);
    }

}

注册为

var settings = new JsonSerializerSettings();
settings.ContractResolver = new SignalRContractResolver();
var serializer = JsonSerializer.Create(settings);
GlobalHost.DependencyResolver.Register(typeof (JsonSerializer), () => serializer);

如果使用自定义的IoC，则可能会遇到问题，因为JsonSerializer是具体类型，而某些IoC(例如 Ninject )将注入未绑定的具体类型.在Ninjects情况下，解决方案是向Ninject注册，而不是向SignalR自己的DependencyResolver

If you use a custom IoC you can run into problems because JsonSerializer is a concrete type and some IoCs like for example Ninject will inject unbound concrete types. In Ninjects case the solution is to register it with Ninject instead of with SignalRs own DependencyResolver

var settings = new JsonSerializerSettings();
settings.ContractResolver = new SignalRContractResolver();
var serializer = JsonSerializer.Create(settings);
kernel.Bind<JsonSerializer>().ToConstant(serializer);
