.net core mvc route的注冊，激活，調用流程
mvc的入口是route，當前請求的url匹配到合適的route之后，mvc根據route所指定的controller和action激活controller并調用action完成mvc的處理流程。下面我們看看服務器是如何調用route的。
core mvc startup基本代碼。重點在AddMvc和UseMvc
public class Startup{ public IConfigurationRoot Configuration { get; } // This method gets called by the runtime. Use this method to add services to the container.
public void ConfigureServices(IServiceCollection services) {
services.AddMvc();
} // This method gets called by the runtime. Use this method to configure the HTTP request pipeline.
public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory) {
app.UseStaticFiles();
app.UseMvc(routes =>
{
routes.MapRoute(
name: "default",
template: "{controller=Home}/{action=Index}/{id?}");
});
}
}
