Temel olarak HTTP durum kodları

Types of HTTP Error and Status Codes

Included in the HTTP server response data for each request is a code number indicating the result of the request. These result codes are three-digit numbers divided into categories as follows:
100-199 : informational status
200-299 : success status
300-399 : redirection status
400-499 : client errors
500-599 : server errors

XmlAttribute bir yerde tanımlıysa, o field ya da property nin tipindeki(class,struct vs.) [XmlType(......)] bir işe yaramaz.

KitapItem sınıfının Title fieldı için farklı bir namespace tanımladık (attribute_namepseysi) ve bunun için d2p1 oluşturulup özelliğin önüne konulduğuna dikkat edelim emi...

Enum gösterimi için [XmlEnum (Name = "enumGorunecekAdi")] kullanılır

XmlIgnore ile serileştirilmesini istemediğimiz field, prop vs. seçilir

XmlInclude ile hangi tiplerin serileştirilip serileştirilmeyeceği belirlenir

WCF'te tanımlı interface(arayüz) istemci(client) de nasıl görünüyor

Temel olarak çalışma şeklim her durumu ince detaylarına varıncaya kadar irdelemektir. Sonuçta en basit haliyle sunucu tarafındaki ServiceContract olarak tanımlı Interface'in istemci tarafında nasıl hayat bulduğunu görmek istedim.

Interface aynı şekliyle istemciye gelmiş ek olarak System.Threading.Tasks.Task<t> metotAdiAsync(parametreleri) diye asenkron metodu eklenmiş.
İşte ekranı görüntüsü:

Bu adres fena anlatmamış: http://www.yazgelistir.com

Yukarıda arayüzün istemci tarafındaki şeklini gördük. Aşağıda ise bu arayüzü System.ServiceModel.ClientBase<Arayuz> ile istemci oluşturmak için nasıl miras alındığını göreceğiz.

Sınıfımız System.ServiceModel.ClientBase sınıfından türetiltiği için Channel özelliği ile kanalın üstünden metot çağrılarını yapabiliyoruz.

UBL içinde cbc, cac gibi isim uzayları ne anlama gelir

Ben de sizin gibi merak ettim ve aşağıdaki bağlantıları okudum. Daha iyi öğrenmek için XML isim uzayları ile ilgili derlemelerimi de okuyabilirsiniz.

cbc = UBL-CommonBasicComponents-2.0.xsd
Common Basic Components kısaltması olarak cbc öneki(prefix) kullanılmış.
cac = CommonAggregateComponents-2.0.xsd
Common Aggregate Components kısaltması olarak cac öneki kullanılmış.

Ayrıca UBL 2.0 içinde kullanılan önekler şunlardır:

XML Namespace (İsim uzayı)

Önce namespace (isim uzayı) nedir?
İçinde eşsiz isimlerin bulunduğu bir kümedir.
Mesela bir babanın çocuklarının isimleri, web adresleri, şehir adları birer isim uzayı oluşturur. Bir isim uzayının bir adı olmalıdır. Tıpkı ailenin soyadı olması gibi.
XML namespace tanımları URI(Uniform Resource Identifier) referanslarıyla yapılır.

URI'nin iki genel şekli vardır: URL(Uniform Resource Locators) ve URN(Uniform Resource Names).

In order to ensure the global uniqueness of URN namespaces, their identifiers (NIDs) are required to be registered with the IANA.

URI'nin 2 Formu olan URL ve URN Örnekleri

<x xmlns:edi='http://ecommerce.example.org/schema'>
  <!-- the "edi" prefix is bound to http://ecommerce.example.org/schema for the "x" element and contents -->
</x>

Bu örnekte: edi öneki 'http://ecommerce.example.org/schema' adresine bağlanmış, hem x elemanı hem de içeriği tarafından kullanılmış.

The prefix xml is by definition bound to the namespace name http://www.w3.org/XML/1998/namespace. It MAY, but need not, be declared, and MUST NOT be bound to any other namespace name. Other prefixes MUST NOT be bound to this namespace name, and it MUST NOT be declared as the default namespace.

xml'i önek olarak, isim uzayı(xml namespace) olarak kullanmamalısınız.

<x xmlns:edi='http://ecommerce.example.org/schema'>
  <!-- the 'taxClass' attribute's namespace is http://ecommerce.example.org/schema -->
  <lineItem edi:taxClass="exempt">Baby food</lineItem>
</x>

taxClass "özelliğinin" isim uzayı ancak önekin kullanılacağı etikegin(tag) içinde ya da bulunduğu etiketi içeren elemanda tanımlanmış olmalıdır. Örnekte taxClass öneki "lineItem" elemanınını içeren "x" elemanında tanımlıdır.

XML tiplerinden NormalizedString ile String farkı

normalizedString

string veri elemanının tanımı:
   <xs:element name="customer" type="xs:string"/>
Veri taşırken:
   <customer>John Smith</customer>
ya da tab tuşu ile şu şekilde değeri olabilir
   <customer>       John Smith     </customer>
ve string kullandığımız için XML işlemcisi elemanın değerini değiştirmeyecektir ve 
  * satır besleme (#xA) 
  * satırbaşı karakterlerini (#xD) 
  * sekme (#x9) karakterleri aynı kalacaktır...

Ama NormalizedString veri elemanını kullanırsak (#xA),(#xD),(#x9) karakterleri, boşluk karakterine(#x20) dönüştürülür...
normalizedString veri elemanının tanımı:
   <xs:element name="customer" type="xs:normalizedString"/>
Veri taşırken:
   <customer>John Smith</customer>
ya da tab tuşu(#x9) ile girilmiş değerler boşluk karakterine(#x20) ye dönüştürülüyor
   <customer>       John Smith     </customer>

You can see that an instance of order sends getQuantityand getProduct messages to the order line. You can also see how we show the order invoking a method on itself and how that method sends getDiscountInfo to an instance of customer.

The diagram, however, doesn’t show everything very well. The sequence of messages getQuantity,getProduct, getPricingDetails, and calculateBasePrice needs to be done for each order line on the order, while calculateDiscounts is invoked just once.

E-Defter

Önce XBRL(Genişletilebilir İşletme Raporlama Dili) ile bilgilerin taşınacağından mütevellit (veled:doğan, tevellüt: doğum, mütevellit:dolayı, şundan sebep) ne olduğunu bir anlayalım.

XBRL bir ticari veya finansal nitelikteki bilgi alışverişi bir yöntemdir.

Kimler özellikle XBRL kullanıyor? 
Muhasebeciler, bankalar, finansal analistler, alacaklılar, ekonomik kurum ve borsalarda XBRL kullanarak başarılı işletmelerin tüm örnekleridir.

YTKK’nın Ticari Defterler, Defter Tutma ve Envanter Başlıklı, Defter Tutma Yükümlülüğü bölümünde; 

“MADDE 64- (1) Her tacir, ticari defterleri tutmak ve defterlerinde, ticari işlemleriyle malvarlığı durumunu, Türkiye Muhasebe Standartlarına ve 88 inci madde hükümleri başta olmak üzere bu Kanuna göre açıkça görülebilir bir şekilde ortaya koymak zorundadır. Defterler, üçüncü kişi uzmanlara, makul bir süre içinde yapacakları incelemede işletmenin faaliyetleri ve finansal durumu hakkında fikir verebilecek şekilde tutulur. İşletme faaliyetlerinin oluşumu ve gelişmesi defterlerden izlenebilmelidir.

(2) Tacir, işletmesiyle ilgili olarak gönderilmiş bulunan her türlü belgenin, fotokopi, karbonlu kopya, mikrofiş, bilgisayar kaydı veya benzer şekildeki bir kopyasını, yazılı, görsel veya elektronik ortamda saklamakla yükümlüdür.

(3) Ticari defterler, açılış ve kapanışlarında noter tarafından onaylanır. Kapanış onayları, izleyen faaliyet döneminin altıncı ayının sonuna kadar yapılır. Şirketlerin kuruluşunda defterlerin açılışı ticaret sicili müdürlükleri tarafından da onaylanabilir. Açılış onayının noter tarafından yapıldığı hâllerde noter, ticaret sicili tasdiknamesini aramak zorundadır. Türkiye Muhasebe Standartlarına göre elektronik ortamda veya dosyalama suretiyle tutulan defterlerin açılış ve kapanış onaylarının şekli ve esasları ile bu defterlerin nasıl tutulacağı Sanayi ve Ticaret Bakanlığınca bir tebliğle belirlenir.

(4) Pay defteri, yönetim kurulu karar defteri ve genel kurul toplantı ve müzakere defteri gibi işletmenin muhasebesiyle ilgili olmayan defterler de ticari defterlerdir.

(5) Yevmiye, defteri kebir ve envanter defteri dışında tutulacak defterler Türkiye Muhasebe Standartları Kurulu tarafından bir tebliğ ile belirlenir.

II - Defterlerin tutulması

MADDE 65- (1) Defterler ve gerekli diğer kayıtlar Türkçe tutulur. Kısaltmalar, rakamlar, harfler ve semboller kullanıldığı takdirde bunların anlamları açıkça belirtilmelidir.

(2) Defterlere yazımlar ve diğer gerekli kayıtlar, eksiksiz, doğru, zamanında ve düzenli olarak yapılır.

(3) Bir yazım veya kayıt, önceki içeriği belirlenemeyecek şekilde çizilemez ve değiştirilemez. Kayıt sırasında mı yoksa daha sonra mı yapıldığı anlaşılmayan değiştirmeler yasaktır.

(4) Defterler ve gerekli diğer kayıtlar, olgu ve işlemleri saptayan belgelerin dosyalanması şeklinde veya veri taşıyıcıları aracılığıyla tutulabilir; şu şartla ki, muhasebenin bu tutuluş biçimleri ve bu konuda uygulanan yöntemler Türkiye Muhasebe Standartlarına uygun olmalıdır. Defterlerin ve gerekli diğer kayıtların elektronik ortamda tutulması durumunda, bilgilerin saklanma süresince bunlara ulaşılmasının ve bu süre içinde bunların her zaman kolaylıkla okunmasının temin edilmiş olması şarttır. Elektronik ortamda tutulma hâlinde birinci ilâ üçüncü fıkra hükümleri kıyas yoluyla uygulanır. 

Kanunun 64. maddesinin 1.fıkrasından da   anlaşılacağı üzere, ticari defterlerin IFRS  ile uyumlu TMS’ye uygun şekilde tutulacağı emredici bir hüküm niteliğindedir.. Bu suretle bilgi kullanıcılara ve üçüncü şahıslara şeffaf, adil ve tutarlı finansal bilgileri sunmak zorunda olan tüm sermeye şirketleri bu hususta, profesyonel muhasebe-denetim meslek mensuplarının seçimi ve eğitimi konusunda finansal tablolardan sorumlu yönetim kurulları-organları çalışmalarına ivedilikle başlamalıdırlar. 

64. maddenin 2. fıkrasının en önemli özelliği, mezkur kanunun gerekçe kısmında açıklanmış ve “ belge yoksa kayıtta yoktur ilkesinden hareketle ( evrak-ı müsbiteye ) , teknik gelişmelere uygun saklama ortamını sınırlayıcı olmayan, gelişmelere açık bir tarzda gösterilmiştir.  Bu bağlamda da geçtiğimiz yıllarda Maliye Bakanlığı’na VUK Mükerrer 242. madde ile “elektronik defter, belge ve kayıtların oluşturulması, kaydedilmesi, iletilmesi, muhafaza ve ibrazı ile defter ve belgelerin elektronik ortamda tutulması ve düzenlenmesi uygulamasına ilişkin usul ve esasları belirleme yetkisi verilmiştir. Aynı maddede, elektronik ortamda tutulmasına ve düzenlenmesine izin verilen defter ve belgelerde yer alması gereken bilgilerin Maliye Bakanlığı'na veya belirleyeceği gerçek veya tüzel kişilere aktarma zorunluluğu getirmeye ve bu hususlarla ilgili uygulamaya ilişkin usul ve esasları tespit etme yetkisi de verilmiş bulunmaktadır.” Maliye Bakanlığı kanunla kendisine verilen yetkisini kullanarak 11.07.2006 tarihinde 361 sıra nolu Vergi Usul Kanunu Genel Tebliği'ni yayımlamış ve uygulama esaslarını belirlemiştir.  Farklı hukuk disiplinleri arasında yapılan bu düzenlemeler  uygulamada herhangi bir sorun yaşanmaması açısından müspet bir gelişme olarak karşımızda durmaktadır. 

6762  sayılı TTK’ dan farklı olarak mezkur kanun ,tüm ticari defterlerin açılış ve kapanış tasdikine tabi olmasını buyurmuş, özellikle çift defter kullanma olasılığını ortadan kaldırmıştır. Pay defteri, karar defteri ve genel kurul karar defterlerinde sıklıkla rastlanan çift defter tutma durumu, biri kapanmadan açılan-kapanan  defterler ihtilaflarda mahkemelerin önüne farklı defterleri çıkarmakta ve hukuki süreç tıkanmaktaydı. Ayrıca  kapanış tasdiklerinin onay süresi, uygulamada zaman sıkışıklığına neden olmaması için faaliyet dönemini izleyen altıncı ayın sonuna uzatılmıştır. 

Defterlerin tutulması başlıklı 65. maddesinin 1 fıkrası, ayrıca yorumlamayı gerektirmeyecek bir şekilde defterlerin ve gerekli diğer kayıtların Türkçe’den başka bir dilde tutulamayacağı emredici niteliktedir. Maddenin ikinci fıkrası bilanço ilkelerine atıfta bulunmuş, muhasebe kayıtlarının eksiksiz doğru ve zamanında yapılmasında TMS ile özdeş olan IFRS’in  kavramsal çerçevesinde de  belirtildiği gibi finansal tablo kullanıcılarının ihtiyacını karşılayacak tam, doğru, zamanında ve düzenli kayıt prensibine uygun bir düzenleme yapmıştır. 

SONUÇ:

Belirli maddelerin niteliklerine göre 1 Temmuz 2012 ve özellikle muhasebe standartlarının uygulanması açısından 1 Ocak 2013 tarihi itibaren uygulamaya girecek Yeni TTK, ticari defterler ve bu defterlerin tutulması açısından IFRS’yi baz almıştır. Artık muhasebe kayıt ve uygulamalarının vergi usul kanunu ve vergi mevzuatına göre tutulmasından ziyade, defter ve kayıtlarda yer alan bilgilerin profesyonel muhasebe-denetim meslek mensuplarınca  IFRS’yi temel alarak hazırlaması emredici niteliktedir. Vergi verileri ve sonuçları sadece muhasebenin bir sonucu olup, amacı olmayacaktır. Yeni TTK’da  şirketlerde en önemli organ olan denetçiler ve uygulamacılar yaklaşan bu sürece uyum sağlamalıdırlar.

Types of WCF Binding

WCF provides nine built-in bindings:

• BasicHttpBinding: Basic web service communication. Exposes WCF services as legacy ASMX web services. Used for interoperability. No security by default.
• WSHttpBinding: Web services with WS-* support. Supports transactions and reliable messaging.
• WSDualHttpBinding: Web services with duplex contract and transaction support.
• WSFederationHttpBinding: Web services with federated security. Supports transactions.
• MsmqIntegrationBinding: Communication directly with MSMQ applications. Supports transactions.
• NetMsmqBinding: Communication between WCF applications by using queuing. Supports transactions.
• NetNamedPipeBinding: Communication between WCF applications on same computer. Supports duplex contracts and transactions.
• NetPeerTcpBinding: Communication between computers across peer-to-peer services. Supports duplex contracts.
• NetTcpBinding: Communication between WCF applications across computers. Supports duplex contracts and transactions.
• Although most bindings will work on scenarios they are not designed for, it's a good practice to choose the right binding for a given a situation. You need to identify your potential use-cases and apply a Binding Decision best practices.

http://wcftutorial.net/WCF-Types-of-Binding.aspx

BasicHttpBinding

It is suitable for communicating with ASP.NET Web services (ASMX)-based services that comfort with WS-Basic Profile conformant Web services.
This binding uses HTTP as the transport and text/XML as the default message encoding.
Security is disabled by default
This binding does not support WS-* functionalities like WS- Addressing, WS-Security, WS-ReliableMessaging
It is fairly weak on interoperability.

WSHttpBinding

Defines a secure, reliable, interoperable binding suitable for non-duplex service contracts.
It offers lot more functionality in the area of interoperability.
It supports WS-* functionality and distributed transactions with reliable and secure sessions using SOAP security.
It uses HTTP and HTTPS transport for communication.
Reliable sessions are disabled by default.

WSDualHttpBinding

This binding is same as that of WSHttpBinding, except it supports duplex service. Duplex service is a service which uses duplex message pattern, which allows service to communicate with client via callback.

In WSDualHttpBinding reliable sessions are enabled by default. It also supports communication via SOAP intermediaries.

WSFederationHttpBinding

This binding support federated security. It helps implementing federation which is the ability to flow and share identities across multiple enterprises or trust domains for authentication and authorization. It supports WS-Federation protocol.

NetTcpBinding

This binding provides secure and reliable binding environment for .Net to .Net cross machine communication. By default it creates communication stack using WS-ReliableMessaging protocol for reliability, TCP for message delivery and windows security for message and authentication at run time. It uses TCP protocol and provides support for security, transaction and reliability.

NetNamedPipeBinding

This binding provides secure and reliable binding environment for on-machine cross process communication. It uses NamedPipe protocol and provides full support for SOAP security, transaction and reliability. By default it creates communication stack with WS-ReliableMessaging for reliability, transport security for transfer security, named pipes for message delivery and binary encoding.

NetMsmqBinding

This binding provides secure and reliable queued communication for cross-machine environment.
Queuing is provided by using MSMQ as transport.
It enables for disconnected operations, failure isolation and load leveling

NetPeerTcpBinding

This binding provides secure binding for peer-to-peer environment and network applications.
It uses TCP protocol for communication
It provides full support for SOAP security, transaction and reliability.

Mustache Template Örneği

Ref: NetTuts - Youtube

// Değişkenleri en üstte tanımlamak iyi, window içinde tanımlamak kötüdür !
var data, template, html;

data = {
  name : "Site adı",
  sites: ["Nettuts+", "Psdtuts+","Mobiletuts+"],
  url: function(){
    return function(text,render){
       text = render(text);
       var url = text.trim().toLowerCase().split('tuts+')[0] + '.tutsplus.com';
       return ''+text+'';
    }
  }

  tempalte = "
{{name}} 
{{#sites}} 
{{#url}} {{.}} {{/url}} 
 {{/sites}} 
";

  html = Mustache.to_html(template, data);

  document.write(html);

ASP.NET Web API

• Extensible Framework for building HTTP based endpoints(PUT,GET,DELETE,POST HTTP de kullanıldığına göre, HTTP based olması normal )
• You can use alone, with MVC4, or you can use with ASP.NET Forms
• Available via NuGet (MVC4 indirmene gerek yok)
  NuGet ile WebAPI yüklemek istediğimizde
  microsoft.web.infrastructure.dll
  Newtonsoft.Json.dll
  system.net.http.formatting.dll
  system.web.http.dll
  system.web.http.webHost.dll
  yüklenmişti.
  
  "http://localhost:27740/HelloApi" url adresi çağırılıyor (GET methoduyla)
  Global.asax uygulama başlatıldığında diyor ki; gelen her şeyi Controller'ına gönder.
  Gelen: "GET" methodu ile "/HelloApi"
  Gideceği yer: "/HelloApiController" daki "Get()" methodu
  
  Default olarak JSON dönüyor
  
  "api/" : URL adresi api ile başlıyorsa,
  
  {controller} : Karşılayacak Controller sınıfı (ApiController dan türemiş) işaret eder,
  
  {action} : Hangi HTTP metoduyla geldiğini (GET,POST, PUT,....),
  
  Bu durumda HTTP metodu talep edilen URL içinde olmak zorunda !
  
• The team decided to make it independent so that WebAPI will not have ASP.NET class dependencies and it can be hosted in console or a Windows service as self-hosting.
• * the actions are dispatched by default based on the HTTP request(GET,POST,PUTE,DELETE e göre hareket edilir).However there is a flexibility to override it so that the WebAPI will use the action name to select the action method within the ApiController().

Neden this veya prototype kullanırız?

PERFORMANS

Eğer bir A fonksyionundan new ile birçok nesne tanımlayacaksak, A fonksiyonunda this.xxx ile tanımlı her fonksiyon tüm nesneler için tek tek oluşturulur.

var A = function () {
    this.x = function () {
        //do something
    };
};

// Aşağıdaki tanımlamada tek bir fonksiyon tüm örnekler için kullanılır
// ve bu şekilde memory daha az kullanılır.
var A = function () { };
A.prototype.x = function () {
    //do something
};

Ref: http://jsperf.com/prototype-vs-this

GİZLEMEK

Fonksiyon içindeki private değişkenleri, public fonksiyonlardan gizlemek istersek, prototype içinde public fonksiyonlarını tanımlarız. Böylece A fonksyonu içindeki private_var erişilmez olur. Sadece A içinde this ile tanımlı kaynaklara prototype içinde tanımlı fonksiyonlar erişir.

__proto__ ne işe yarar

Bir fonksiyonun prototype özelliği otomatik olarak tanımlanır ve içindeki bilgiler o fonksiyondan üretilen nesnelere geçer. Üretilen her nesne __proto__ bilgisi içinde fonksyionun prototype özelliğindeki nesneyi saklar ve aranan her property eğer birinci seviyede nesnede yoksa __proto__ içinde aranır. Bulunamazsa __proto__.__proto__ içinde ve en son __proto__ ya kadar aranır.

prototype.constructor ne işe yarar

Fonksiyonun varsayılan özelliği prototype idi ve constructor ile __proto__ dan oluşuyordu.

Fonksiyonun atasını prototype içinden öğreniyoruz.

Function dan miras alınanlar:

Eğer prototype özelliğini başka bir fonksiyondan olma nesne ile ezersek:

Eğer daha A fonksiyonunun prototype'ını B fonksiyonuyla ezip,
A fonksiyonundan olma bir a nesnesinin constructor fonksiyonundan c nesnesi yaratmak istersek,
elbetteki B fonksiyonundan üretilmiş olacak çünkü A'nın prototype özelliğini B yapmıştık.

Kısaca constructor ile objenin atasına ait fonksiyona bağ kurmuş oluyoruz. Eğer nesnenin üstünden new ile bir başka nesne yaratmak istersek constructor fonksiyonu işimize yarayacaktır.

Javascript Sınıflarında prototype atanması

1)

2)


Sınıfların durumunu daha derin incelersek:

Herhangi bir inheritance(miras, kalıtım) uygulanmadığı için B sınıfı varsayılan olarak Object sınıfından miras alır. Bu durumda B'den yaratılacak nesneler için ilk aranacak metotlar B sınıfının içindekiler sonra B'nin miras aldığı Object sınıfı içindekiler olacak.
Nesnenin daima __proto__ su vardır ve inherit ettiği sınıfların bilgilerini barındırır.
Bir nesne içinde property araması yapıldığında önce kendi içinde (hasOwnProperty) sonra inherit ettiği sınıfların içinde propertylerde arama yapar.

var b = new B();
b.__proto__ 
B {}
b.__proto__.__proto__
Object {}
b.__proto__.__proto__.__proto__
null

Object.create ile inheritance:


new Operatörüyle inheritance:


B nin prototype'ı için Object.create ile A yı B sınıfının atası olarak tayin ettiğimizde, A dan bir nesne yaratılmaz ve tüm property leri B sınıfından yaratılan nesnelere geçirilmez.

Miras alan sınıfa, sanki atadan geliyormuş gibi yeni fonksiyon ve özellikler eklemek

Object.create(param1,param2)
param1: Miras alınan sınıf
param2: Sanki miras alınan sınıftan geliyormuş gibi eklenen fonksiyon ve özellikler. Dikkat edilecek nokta: Miras alınan sınıfa yeni eklenen fonksiyon ve özellikler geçmez!

KALITIMI YOK ETMEK

null veya Object.create(null) ile sınıfın, ata sınıfla ilişiği kesildiği anda, prototype'ı null yapılan sınıflardan türetilen nesnelerin __proto__ özelliği Object ile yer değişir.
