MVC

當網站出錯時有問題卻沒有紀錄怎麼辦？用Application_Error來Hold住全場吧 !!

Global.asax

protected void Application_Error(object sender, EventArgs e)
{
	var rawUrl = Request.RawUrl;
	var ex = Server.GetLastError();
	Debug.WriteLine("RawUrl: {0}", rawUrl);
	Debug.WriteLine("Ex: {0}", ex.Message);
	Debug.WriteLine("StackTrace: {0}", ex.StackTrace);

	//若網頁沒有撰寫任何的錯誤處理，或是沒有回收清除(Server.ClearError)，最後將顯示預設錯誤畫面；反之若有清除則不再往下一個除錯流程。
	Server.ClearError();

	//導回首頁
	Response.Redirect("/");
}

protected void Application_Error(object sender, EventArgs e)

{

var rawUrl = Request.RawUrl;

var ex = Server.GetLastError();

Debug.WriteLine("RawUrl: {0}", rawUrl);

Debug.WriteLine("Ex: {0}", ex.Message);

Debug.WriteLine("StackTrace: {0}", ex.StackTrace);

//若網頁沒有撰寫任何的錯誤處理，或是沒有回收清除(Server.ClearError)，最後將顯示預設錯誤畫面；反之若有清除則不再往下一個除錯流程。

Server.ClearError();

//導回首頁

Response.Redirect("/");

}

之前嘗試很多次都失敗，這次終於成功註冊Controller、Service與Repository了，來記錄一下設定檔。

AutofacConfig.cs

/// <summary>
/// DI設定檔
/// </summary>
public class AutofacConfig
{
	/// <summary>
	/// 註冊DI注入物件資料
	/// </summary>
	public static void Register()
	{
		// 容器建立者
		ContainerBuilder builder = new ContainerBuilder();

		// 註冊Controllers
		builder.RegisterControllers(Assembly.GetExecutingAssembly());

		// 註冊Service
		builder.RegisterAssemblyTypes(Assembly.GetExecutingAssembly())
			   .Where(t => t.Name.EndsWith("Service"))
			   .AsSelf();

		// 註冊Repository
		builder.RegisterAssemblyTypes(Assembly.GetExecutingAssembly())
			   .Where(t => t.Name.EndsWith("Repository"))
			   .AsSelf();

		// 建立容器
		IContainer container = builder.Build();

		// 解析容器內的型別
		AutofacDependencyResolver resolver = new AutofacDependencyResolver(container);

		// 建立相依解析器
		DependencyResolver.SetResolver(resolver);
	}
}

builder.RegisterControllers(Assembly.GetExecutingAssembly());

builder.RegisterAssemblyTypes(Assembly.GetExecutingAssembly())

.AsSelf();

// 建立容器

IContainer container = builder.Build();

// 解析容器內的型別

AutofacDependencyResolver resolver = new AutofacDependencyResolver(container);

// 建立相依解析器

DependencyResolver.SetResolver(resolver);

}
