==Web Service laborok más tárgyakból==

* [[IIRLaborWS|Integrált információs rendszerek]] &mdash; Visual Studio 2005 + Web Service Enhancement 3
* [[Szoftverfejlesztés J2EE platformon - Labor: Web Service|Szoftverfejlesztés J2EE platformon]] &mdash; NetBeans 5.5

==Code-first==

* New C# Console Project: AmazonClient
* Add Web Reference
** URL: {{InLineFileLink|Infoszak|ElosztottLaborWebService|amazon.wsdl|amazon.wsdl}} (eredetileg: http://lancelot.aut.bme.hu/temp/Amazon.wsdl)
** Web reference name: AmazonProxy
* Double click a Web References / AmazonProxy-n

===Könyvek keresése és kilistázása===

<code class="pre">using AmazonClient.AmazonProxy;
&nbsp;
static void Main(string[] args)
{
	 AWSECommerceService service = new AWSECommerceService();
&nbsp;
	 ItemSearchRequest request = new ItemSearchRequest();
	 request.SearchIndex = "Books";
	 request.Power = "title: .NET";
	 request.Sort = "salesrank";
	 request.ResponseGroup = new string[] { "Small" };
&nbsp;
	 ItemSearchRequest[] requests = 
		  new ItemSearchRequest[] { request };
&nbsp;
	 ItemSearch itemSearch = new ItemSearch();
	 itemSearch.AWSAccessKeyId = "079ZMCK5940PKP7WVAG2";
	 itemSearch.Request = requests;
&nbsp;
	 ItemSearchResponse resp = service.ItemSearch(itemSearch);
&nbsp;
	 Items info = resp.Items[0];
	 foreach (Item item in info.Item)
	 {
		  foreach (string name in item.ItemAttributes.Author)
				Console.Write(name + ", ");
		  Console.WriteLine("\n{0}\n", item.ItemAttributes.Title);
	 }
}</code>

==Contract-first==

* New Blank Solution
* Add New Item: PoRequest.xml (Product Order Request) <br><code style="white-space:pre">&lt;?xml version="1.0" encoding="utf-8"?&gt;<br>&lt;PoRequest&gt;<br>	&lt;Product name="pen" quantity="10"/&gt;<br>	&lt;Product name="paper" quantity="1000"/&gt;<br>&lt;/PoRequest&gt;</code>
** XML / Create Schema
** Save as PoRequest.xsd
** Add Existing Item: PoRequest.xsd
** targetNameSpace: http://www.aut.bme.hu/PoRequest
* Add New Item: PoResponse.xml <br><code style="white-space:pre">&lt;?xml version="1.0" encoding="utf-8"?&gt;<br>&lt;PoResponse&gt;<br>	&lt;Confirmation price="500"/&gt;<br>&lt;/PoResponse&gt;</code>
** az előbbieket eljátszani a PoResponse-ra is
* wsdl-t letölteni és hozzáadni a solution-höz: {{InLineFileLink|Infoszak|ElosztottLaborWebService|PoService.wsdl|PoService.wsdl}}

* Stub generálás: VS2005 Command Prompt-ból: <br> wsdl /server PoService.wsdl PoRequest.xsd PoResponse.xsd
** Generálódott egy PoServicePort.cs
* Add New Web Site
** ASP.NET Web Service
** D:\User\erl\ContractFirst\Po
** App_Code könyvtárba bemásolni a PoServicePort.cs-t
** service.asmx / Set As Start Page
** ...\ContractFirst\Po / Set As Startup Project, elindítani
* Kliens oldali proxy generálás: <br> wsdl PoService.wsdl PoRequest.xsd PoResponse.xsd
* Add New Project / C# Console Application: PoClient
* Add Reference: .NET / System.Web.Services
* PoServicePort.cs-t átrakni a PoClient könyvtárba és felvenni a projektbe
* PoClient / Set As Startup Project
* A wsdl.exe inkompatibilis stubot és proxyt generált: ki kell javítani a proxyban 1 sort: <br> =public PoResponse SubmitPo([System.Xml.Serialization.XmlArrayAttribute(Namespace="http://www.aut.bme.hu/PoService")] [System.Xml.Serialization.XmlArrayItemAttribute("PoRequestProduct", IsNullable=false)] PoRequestProduct[] PoRequest) {=

===Po / Service.cs===

<code class="pre">using System;
using System.Web;
using System.Web.Services;
using System.Web.Services.Protocols;
&nbsp;
[System.CodeDom.Compiler.GeneratedCodeAttribute("wsdl", "2.0.50727.42")]
[System.Web.Services.WebServiceAttribute(Namespace = "http://www.aut.bme.hu/PoService")]
[System.Web.Services.WebServiceBindingAttribute(Name = "PoService",
	 Namespace = "http://www.aut.bme.hu/PoService")]
public class Service : PoServicePort
{
	 [System.Web.Services.WebMethodAttribute()]
	 [System.Web.Services.Protocols.SoapDocumentMethodAttribute(
		  "http://www.aut.bme.hu/PoService:submitPoIn",
		  Use = System.Web.Services.Description.SoapBindingUse.Literal,
		  ParameterStyle = System.Web.Services.Protocols.SoapParameterStyle.Bare)]
	 [return: System.Xml.Serialization.XmlElementAttribute("PoResponse",
		  Namespace = "http://www.aut.bme.hu/PoResponse")]
	 public override PoResponse SubmitPo(PoRequestProduct[] PoRequest)
	 {
		  PoResponse resp = new PoResponse();
		  resp.Confirmation = new PoResponseConfirmation();
		  foreach (PoRequestProduct p in PoRequest)
				resp.Confirmation.price += p.quantity;
		  return resp;
	 }
}</code>

Az attribútumokat a PoServicePort.cs-ből kellett kimásolni.

===PoClient / Program.cs===

<code class="pre">using System;
using System.Collections.Generic;
using System.Text;
&nbsp;
namespace PoClient
{
	 class Program
	 {
		  static void Main(string[] args)
		  {
				PoRequestProduct[] products = new PoRequestProduct[1];
				products[0] = new PoRequestProduct();
				products[0].name = "Pen";
				products[0].quantity = 5;
				PoServicePort port = new PoServicePort();
				// tálcán az ASP.NET Development Server ikon mutatja a portot
				// a végleges verzióban a wsdl fogja tartalmazni az url-t
				port.Url = "http://localhost:1529/Po/Service.asmx";
&nbsp;
				PoResponse resp = port.SubmitPo(products);
				Console.WriteLine(resp.Confirmation.price);
		  }
	 }
}</code>
