.Net5 之 IHttpContextAccessor注册

1. 一般情况下我们需要通过HttpContext 来获取当前用户请求服务器得到认证的信息.
2. 在.Net5中如果要使用HttpContext需要先在容器中注册.

public void ConfigureServices(IServiceCollection services)
{
      services.AddSingleton<IHttpContextAccessor, HttpContextAccessor>();
}

3. 然后使用, 但是为了方便操作, 一般会建一个静态类, 用静态的方式获取该服务.

public static class StaticHttpContextExtensions
{
 public static IApplicationBuilder UseStaticHttpContext(this IApplicationBuilder app)
        {
            var httpContextAccessor = app.ApplicationServices.GetRequiredService<IHttpContextAccessor>();
           Utilities.HttpContext.Configure(httpContextAccessor);
            return app;
        }
}

4. 使用

public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
{
      app.UseStaticHttpContext();
}
