设置的CurrentCulture多语言ASP.NET的WebAPI应用程序的最佳地点

问题描述

（Best地方设置的CurrentCulture为）我正在寻找一个全球性的方式做同样的ASP.NET的WebAPI多种语言的ASP.NET MVC Web应用程序。

based on this question (Best place to set CurrentCulture for multilingual ASP.NET MVC web applications) I'm looking for a global way to do the same for ASP.NET WebAPI.

我的当前实现ASP.NET MVC看起来是这样的：

My current implementation for ASP.NET MVC looks like this:

public class MvcApplication : System.Web.HttpApplication
{
    protected void Application_Start()
    {

        AreaRegistration.RegisterAllAreas();
        GlobalConfiguration.Configure(WebApiConfig.Register);
        FilterConfig.RegisterGlobalFilters(GlobalFilters.Filters);
        RouteConfig.RegisterRoutes(RouteTable.Routes);
        BundleConfig.RegisterBundles(BundleTable.Bundles);


        ControllerBuilder.Current.SetControllerFactory(new DefaultControllerFactory(new CultureAwareControllerActivator()));


    }
}


public class CultureAwareControllerActivator : System.Web.Mvc.IControllerActivator
{
    public System.Web.Mvc.IController Create(System.Web.Routing.RequestContext requestContext, System.Type controllerType)
    {
        string cultureName = null;

        // Attempt to read the culture cookie from Request
        HttpCookie cultureCookie = requestContext.HttpContext.Request.Cookies["_culture"];
        if (cultureCookie != null)
            cultureName = cultureCookie.Value;
        else
            cultureName = requestContext.HttpContext.Request.UserLanguages != null && requestContext.HttpContext.Request.UserLanguages.Length > 0 ?
                      requestContext.HttpContext.Request.UserLanguages[0] :  // obtain it from HTTP header AcceptLanguages
                      null;

        // Validate culture name
        cultureName = RoedingGmbh.Pis2Go.Web.Mvc.Helpers.CultureHelper.GetImplementedCulture(cultureName); // This is safe

        // Modify current thread's cultures
        System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo(cultureName);
        // Currently the UI Language is only english
        //Thread.CurrentThread.CurrentUICulture = Thread.CurrentThread.CurrentCulture;

        return DependencyResolver.Current.GetService(controllerType) as IController;
    }
}

我试图做同样的事情在ASP.NET MVC中，但以下code不能正常工作。

I'm trying to do the same things as in ASP.NET MVC, but following code doesn't work properly.

 public static class WebApiConfig
 {
      public static void Register(HttpConfiguration config)
      {
            // Web API configuration and services

            // Web API routes
            config.MapHttpAttributeRoutes();

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

            GlobalConfiguration.Configuration.Services.Replace(typeof(System.Web.Http.Dispatcher.IHttpControllerActivator), new CultureAwareHttpControllerActivator());

          }
 }


 public class CultureAwareHttpControllerActivator : System.Web.Http.Dispatcher.IHttpControllerActivator
 {
     public System.Web.Http.Controllers.IHttpController Create(System.Net.Http.HttpRequestMessage request, System.Web.Http.Controllers.HttpControllerDescriptor controllerDescriptor, Type controllerType)
     {
        System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("DE-de");
        return GlobalConfiguration.Configuration.DependencyResolver.GetService(controllerType) as System.Web.Http.Controllers.IHttpController;
     }
 }

使用了code，的WebAPI找不到任何路线了:(
我有什么做的就是这个工作！

With that code, WebAPI cannot find any route anymore :(What have I to do to get this to work!

问候，

推荐答案

如果你想为整个应用程序全球定位，你可以把一套文化code到的了的BeginRequest方法的HttpApplication全球ASAX文件。这将设置你的文化在最首位的每个请求，并会影响到每一个MVC和的WebAPI请求。

If you want global localization for whole application, you can put the set culture code into the BeginRequest method of the HttpApplication in global asax file. This will set your culture in the most first place of each request and will affect every MVC and webapi request.
