一般一个已经实现功能的WEB Server会发布自己的WSDL文件，供客户端生成代理类。 但有时是先有的server与client交互的接口定义（WSDL）文件，然后由server和client端分别写程序，一个提供web服务，一个使用web服务。 以下介绍如何由已有的WSDL文件在VS2005中生成server端代码。 1）使用VS2005提供的工具wsdl.exe由WSDL文件生成cs文件： 使用wsdl.exe的/serverInterface选项（或缩写的 /si）指定输入的wsdl文件（注意，如果要转换的wsdl文件中import了其他wsdl文件，则所有文件都应列出，包括使用到的xsd文件也应列出）。输出将是 一个代码文件（默认是C#的，如果需要别的语言，参考MSDN中wsdl.exe的使用说明），其中包含每个 wsdl 绑定的接口。 示例：假设ServerInterfaceSample.wsdl文件中import了importedSample.wsdl，并使用Service.xsd作为schema文件； wsdl.exe /si ServerInterfaceSample.wsdl importedSample.wsdl Service.xsd 生成代码如下: //------------------------------------------------------------------------------ // // This code was generated by a tool. // Runtime Version:2.0.50727.42 // // Changes to this file may cause incorrect behavior and will be lost if // the code is regenerated. // //------------------------------------------------------------------------------ using System; using System.ComponentModel; using System.Diagnostics; using System.Web.Services; using System.Web.Services.Protocols; using System.Xml.Serialization; // // This source code was auto-generated by wsdl, Version=2.0.50727.42. // /// [System.CodeDom.Compiler.GeneratedCodeAttribute("wsdl", "2.0.50727.42")] [System.Web.Services.WebServiceBindingAttribute(Name="org.csapi.cs.IpChargingManagerSOAPBinding", Namespace="")] public interface IOrgcsapicsIpChargingManagerSOAPBinding { /// [System.Web.Services.WebMethodAttribute()] [System.Web.Services.Protocols.SoapDocumentMethodAttribute("", RequestElementName="org.csapi.cs.IpChargingManager.createChargingSession", RequestNamespace="", ResponseElementName="org.csapi.cs.IpChargingManager.createChargingSessionResult", ResponseNamespace="", Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)] [return: System.Xml.Serialization.XmlElementAttribute("return", Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] orgcsapicsTpChargingSessionID createChargingSession([System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] EndpointReferenceType appChargingSession, [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] string sessionDescription, [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] orgcsapicsTpMerchantAccountID merchantAccount, [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] orgcsapiTpAddress user, [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] orgcsapicsTpCorrelationID correlationID); /// [System.Web.Services.WebMethodAttribute()] [System.Web.Services.Protocols.SoapDocumentMethodAttribute("", RequestElementName="org.csapi.cs.IpChargingManager.createSplitChargingSession", RequestNamespace="", ResponseElementName="org.csapi.cs.IpChargingManager.createSplitChargingSessionResult", ResponseNamespace="", Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)] [return: System.Xml.Serialization.XmlElementAttribute("return", Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] orgcsapicsTpChargingSessionID createSplitChargingSession([System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] EndpointReferenceType appChargingSession, [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] string sessionDescription, [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] orgcsapicsTpMerchantAccountID merchantAccount, [System.Xml.Serialization.XmlArrayAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] [System.Xml.Serialization.XmlArrayItemAttribute("item", Form=System.Xml.Schema.XmlSchemaForm.Unqualified, IsNullable=false)] orgcsapiTpAddress[] users, [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] orgcsapicsTpCorrelationID correlationID); /// [System.Web.Services.WebMethodAttribute()] [System.Web.Services.Protocols.SoapDocumentMethodAttribute("", RequestElementName="org.csapi.IpService.setCallback", RequestNamespace="", ResponseElementName="org.csapi.IpService.setCallbackResult", ResponseNamespace="", Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)] void setCallback([System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] EndpointReferenceType appInterface); /// [System.Web.Services.WebMethodAttribute()] [System.Web.Services.Protocols.SoapDocumentMethodAttribute("", RequestElementName="org.csapi.IpService.setCallbackWithSessionID", RequestNamespace="", ResponseElementName="org.csapi.IpService.setCallbackWithSessionIDResult", ResponseNamespace="", Use=System.Web.Services.Description.SoapBindingUse.Literal, ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)] void setCallbackWithSessionID([System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] EndpointReferenceType appInterface, [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] int sessionID); } 代码中有一个接口类,并给出了接口函数声明. 此功能的优点是将实现代码和协定代码（如接口所定义的那样）分开。 如果更改 wsdl，然后重新生成接口，则不会丢失任何实现代码。 若要遵循建议的设计指南，则不应将任何代码放置在更改 wsdl 协定的实现中。 同样，不应使用影响运行时行为的代码来更改接口。 协定和实现的详细信息应该分开。 2) 在VS IDE中新建一个web service工程,加入新生成的**Interface.cs文件. 将自动生成的Service类改为从加入的Interface接口类派生,并实现所有的接口函数.(注意名空间一致) [WebService(Namespace = "")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] public class Service : IOrgcsapicsIpChargingManagerSOAPBinding { public orgcsapicsTpChargingSessionID createChargingSession(EndpointReferenceType appChargingSession, string sessionDescription, orgcsapicsTpMerchantAccountID merchantAccount, orgcsapiTpAddress user,orgcsapicsTpCorrelationID correlationID) { return new orgcsapicsTpChargingSessionID(); } public orgcsapicsTpChargingSessionID createSplitChargingSession(EndpointReferenceType appChargingSession, string sessionDescription, orgcsapicsTpMerchantAccountID merchantAccount, orgcsapiTpAddress[] users, orgcsapicsTpCorrelationID correlationID) { return new orgcsapicsTpChargingSessionID(); } public void setCallback(EndpointReferenceType appInterface) { } public void setCallbackWithSessionID(EndpointReferenceType appInterface, int sessionID) { } } 大功告成,在实现函数中加入处理代码就可以了. |
