如何将IStringLocalizer注入IApplicationModelConvention？

Posted 2021-03-27

我有一个自定义约定，需要在其中的本地化字符串。 AFAIK实例化IStringLocalizer的唯一方法是DependencyInjection。

如何在CustomConvention中使用IStringLocalizer？

该惯例是这样注册的

public void ConfigureServices(IServiceCollection services)
{
     //First I register the localization settings
     services.AddLocalization(o =>
     {
        o.ResourcesPath = "Resources";
     });

      services.AddMvc(options =>
      {
           //My custom convention, I would need to inject an IStringLocalizer  
           //into constructor here, but I can' instantiate it
           options.Conventions.Add(new LocalizationRouteConvention());
      })
}

答案

我的解决方案并不漂亮。

您可以执行类似的操作，构建服务提供程序以获取StringLocalizer的实例。

public void ConfigureServices(IServiceCollection services)
{
     //First I register the localization settings
     services.AddLocalization(o =>
     {
        o.ResourcesPath = "Resources";
     });

     var stringLocalizer = services.BuildServiceProvider().GetService<IStringLocalizer<Resource>>();

     services.AddMvc(options =>
     {
          //My custom convention, I would need to inject an IStringLocalizer  
          //into constructor here, but I can' instantiate it
          options.Conventions.Add(new LocalizationRouteConvention(stringLocalizer));
     })
}
