刚接触netcore, 以下我正在使用的配置说明以及需要注入的几点
1.我在项目中因为不想使用构造函数注入,所以我引用了第三方的Autofac包来管理我的service,在controller中只需要 创建 public iClass class{get;set;}即可
2.service注入我采用的是dll反射进行注入,
注意如下代码 var files = System.IO.Directory.GetFiles(AppContext.BaseDirectory, "*.BLL.dll"); 由于我的业务层都放在BLL中,所以我只需要搜索根目录下的BLL文件进行注入即可
3. 项目中如果使用了Areas ,需要添加以下代码
app.UseMvc(routes =>
{
routes.MapRoute(
name: "areaRoute",
template: "{area:exists}/{controller=Home}/{action=Index}/{id?}");//控制器分层
如果需要将areas单独建成项目,需要在ConfigureServices(IServiceCollection services)中如下代码,该代码是将子项目中的controller注入到主项目中
#region mvc 区域分项目时调用
var manager = new ApplicationPartManager();
files = System.IO.Directory.GetFiles(AppContext.BaseDirectory, "*.Web.dll");//获取所有的web.dll
if (files != null && files.Length > 0)
{
foreach (var file in files)
{
manager.ApplicationParts.Add(new AssemblyPart(Assembly.LoadFrom(file)));
}
}
manager.FeatureProviders.Add(new ControllerFeatureProvider());
var feature = new ControllerFeature();
manager.PopulateFeature(feature);
#endregion
在子项目中属性 ---》生成事件----》后期生成事件中添加如下代码
mkdir "$(SolutionDir)$(SolutionName).Web\Areas\{AreaName}\Views"
xcopy "$(ProjectDir)Views" "$(SolutionDir)$(SolutionName).Web\Areas\{AreaName}\Views" /S /E /C /Y

}

#region //身份认证时需要使用的方法

options.IdleTimeout = TimeSpan.FromMinutes(ApplicationEnvironments.Site.SessionTimeout);
});
services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
.AddCookie(CookieAuthenticationDefaults.AuthenticationScheme, options =>
{
options.DataProtectionProvider= DataProtectionProvider.Create(new DirectoryInfo(AppDomain.CurrentDomain.BaseDirectory+ "/shared-auth-ticket-keys/"));
options.Cookie.Name = ApplicationEnvironments.Site.CookieName;
options.Cookie.Path = "/";
options.LoginPath = new PathString("/login");
options.AccessDeniedPath = new PathString("/Forbidden"); //禁止访问路径:当用户试图访问资源时,但未通过该资源的任何授权策略,请求将被重定向到这个相对路径。
// options.SlidingExpiration = false; //Cookie可以分为永久性的和临时性的。 临时性的是指只在当前浏览器进程里有效,浏览器一旦关闭就失效(被浏览器删除)。 永久性的是指Cookie指定了一个过期时间,在这个时间到达之前,此cookie一直有效(浏览器一直记录着此cookie的存在)。 slidingExpriation的作用是,指示浏览器把cookie作为永久性cookie存储,但是会自动更改过期时间,以使用户不会在登录后并一直活动,但是一段时间后却自动注销。也就是说,你10点登录了,服务器端设置的TimeOut为30分钟,如果slidingExpriation为false,那么10:30以后,你就必须重新登录。如果为true的话,你10:16分时打开了一个新页面,服务器就会通知浏览器,把过期时间修改为10:46。 更详细的说明还是参考MSDN的文档。
