C#动态调用带有SoapHeader验证的WebServices
http://blog.csdn.net/u012995964/article/details/54573143
本文记录C#中通过反射动态的调用带有SoapHeader验证的WebServices服务，基于 Windows8.1、Visual Studio 2013、IIS8 环境实现。
关于WebService创建、部署及静态调用等内容，可以见：C#静态调用带有SoapHeader验证的WebServices。
创建动态调用类
创建一个客户端控制台程序，并新建类DynamicInvokeService.cs , 文件内容如下：
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Net; using System.IO; using System.Web.Services.Description; using System.CodeDom; using Microsoft.CSharp; using System.CodeDom.Compiler; using System.Reflection; namespace DynamicInvoke { /// <summary> /// Web Service服务类 /// </summary> public class WSHelper { /// < summary> /// 动态调用web服务 （不含有SoapHeader） /// < /summary> /// < param name="url">WSDL服务地址< /param> /// < param name="methodname">方法名< /param> /// < param name="args">参数< /param> /// < returns>< /returns> public static object InvokeWebService(string url, string methodname, object[] args) { return WSHelper.InvokeWebService(url, null, methodname, null, args); } /// <summary> /// 动态调用web服务（含有SoapHeader） /// </summary> /// <param name="url"></param> /// <param name="methodname"></param> /// <param name="soapHeader"></param> /// <param name="args"></param> /// <returns></returns> public static object InvokeWebService(string url, string methodname, SoapHeader soapHeader, object[] args) { return WSHelper.InvokeWebService(url, null, methodname, soapHeader, args); } /// < summary> /// 动态调用web服务 /// < /summary> /// < param name="url">WSDL服务地址< /param> /// < param name="classname">类名< /param> /// < param name="methodname">方法名< /param> /// < param name="args">参数< /param> /// < returns>< /returns> public static object InvokeWebService(string url, string classname, string methodname, SoapHeader soapHeader, object[] args) { string @namespace = "EnterpriseServerBase.WebService.DynamicWebCalling"; if ((classname == null) || (classname == "")) { classname = WSHelper.GetWsClassName(url); } try { //获取WSDL WebClient wc = new WebClient(); Stream stream = wc.OpenRead(url + "?WSDL"); ServiceDescription sd = ServiceDescription.Read(stream); ServiceDescriptionImporter sdi = new ServiceDescriptionImporter(); sdi.AddServiceDescription(sd, "", ""); CodeNamespace cn = new CodeNamespace(@namespace); //生成客户端代理类代码 CodeCompileUnit ccu = new CodeCompileUnit(); ccu.Namespaces.Add(cn); sdi.Import(cn, ccu); CSharpCodeProvider icc = new CSharpCodeProvider(); //设定编译参数 CompilerParameters cplist = new CompilerParameters(); cplist.GenerateExecutable = false; cplist.GenerateInMemory = true; cplist.ReferencedAssemblies.Add("System.dll"); cplist.ReferencedAssemblies.Add("System.XML.dll"); cplist.ReferencedAssemblies.Add("System.Web.Services.dll"); cplist.ReferencedAssemblies.Add("System.Data.dll"); //编译代理类 CompilerResults cr = icc.CompileAssemblyFromDom(cplist, ccu); if (cr.Errors.HasErrors) { System.Text.StringBuilder sb = new System.Text.StringBuilder(); foreach (System.CodeDom.Compiler.CompilerError ce in cr.Errors) {http://localhost:38076/Properties/ sb.Append(ce.ToString()); sb.Append(System.Environment.NewLine); } throw new Exception(sb.ToString()); } //保存生产的代理类，默认是保存在bin目录下面 TextWriter writer = File.CreateText("MyWebServices.cs"); icc.GenerateCodeFromCompileUnit(ccu, writer, null); writer.Flush(); writer.Close(); //生成代理实例 System.Reflection.Assembly assembly = cr.CompiledAssembly; Type t = assembly.GetType(@namespace + "." + classname, true, true); object obj = Activator.CreateInstance(t); #region 设置SoapHeader FieldInfo client = null; object clientkey = null; if (soapHeader != null) { client = t.GetField(soapHeader.ClassName + "Value"); //获取客户端验证对象 soap类 Type typeClient = assembly.GetType(@namespace + "." + soapHeader.ClassName); //为验证对象赋值 soap实例 clientkey = Activator.CreateInstance(typeClient); //遍历属性 foreach (KeyValuePair<string, object> property in soapHeader.Properties) { typeClient.GetField(property.Key).SetValue(clientkey, property.Value); // typeClient.GetProperty(property.Key).SetValue(clientkey, property.Value, null); } } #endregion if (soapHeader != null) { //设置Soap头 client.SetValue(obj, clientkey); //pro.SetValue(obj, soapHeader, null); } //调用指定的方法 System.Reflection.MethodInfo mi = t.GetMethod(methodname); //方法名错误（找不到方法），给出提示 if (null == mi) { return "方法名不存在，请检查方法名是否正确！"; } return mi.Invoke(obj, args); // PropertyInfo propertyInfo = type.GetProperty(propertyname); //return propertyInfo.GetValue(obj, null); } catch (Exception ex) { throw new Exception(ex.InnerException.Message, new Exception(ex.InnerException.StackTrace)); } } private static string GetWsClassName(string wsUrl) { string[] parts = wsUrl.Split('/'); string[] pps = parts[parts.Length - 1].Split('.'); return pps[0]; } /// <summary> /// 构建SOAP头，用于SoapHeader验证 /// </summary> public class SoapHeader { /// <summary> /// 构造一个SOAP头 /// </summary> public SoapHeader() { this.Properties = new Dictionary<string, object>(); } /// <summary> /// 构造一个SOAP头 /// </summary> /// <param name="className">SOAP头的类名</param> public SoapHeader(string className) { this.ClassName = className; this.Properties = new Dictionary<string, object>(); } /// <summary> /// 构造一个SOAP头 /// </summary> /// <param name="className">SOAP头的类名</param> /// <param name="properties">SOAP头的类属性名及属性值</param> public SoapHeader(string className, Dictionary<string, object> properties) { this.ClassName = className; this.Properties = properties; } /// <summary> /// SOAP头的类名 /// </summary> public string ClassName { get; set; } /// <summary> /// SOAP头的类属性名及属性值 /// </summary> public Dictionary<string, object> Properties { get; set; } /// <summary> /// 为SOAP头增加一个属性及值 /// </summary> /// <param name="name">SOAP头的类属性名</param> /// <param name="value">SOAP头的类属性值</param> public void AddProperty(string name, object value) { if (this.Properties == null) { this.Properties = new Dictionary<string, object>(); } Properties.Add(name, value); } } } }
注意代码中有如下代码：
//保存生产的代理类，默认是保存在bin目录下面 TextWriter writer = File.CreateText("MyWebServices.cs"); icc.GenerateCodeFromCompileUnit(ccu, writer, null); writer.Flush(); writer.Close();
此代码可以保存生成的代理类，可以在工程目录下的bin目录下查看文件。
测试端代码
using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace DynamicInvokeService { class Program { static void Main(string[] args) { string url = "http://192.168.1.109:81/WebService1.asmx"; //string url = "http://192.168.1.109:82/WebService2.asmx"; Dictionary<string, object> properties = new Dictionary<string, object>(); properties.Add("UserName", "admin"); properties.Add("PassWord", "admin123"); DynamicInvoke.WSHelper.SoapHeader soapHeader = new DynamicInvoke.WSHelper.SoapHeader("MySoapHeader", properties); Object obj1 = DynamicInvoke.WSHelper.InvokeWebService(url, "HelloWorld", null); Object obj2 = DynamicInvoke.WSHelper.InvokeWebService(url, "HelloWorld", soapHeader, null); Object obj3 = DynamicInvoke.WSHelper.InvokeWebService(url, "getNum", new Object[] { 1, 2 }); Object obj4 = DynamicInvoke.WSHelper.InvokeWebService(url, "getNum", soapHeader, new Object[] { 1, 2 }); Object obj5 = DynamicInvoke.WSHelper.InvokeWebService(url, "getList", null); Object obj6 = DynamicInvoke.WSHelper.InvokeWebService(url, "getList", soapHeader, null); Console.WriteLine("无SoapHeader调用HelloWorld：" + obj1); Console.WriteLine("有SoapHeader调用HelloWorld：" + obj2); Console.WriteLine("无SoapHeader调用getNum：" + obj3); Console.WriteLine("有SoapHeader调用getNum：" + obj4); Console.WriteLine("无SoapHeader调用无验证方法getList：" + obj5.GetType().IsArray); Console.WriteLine("有SoapHeader调用无验证方法getList：" + obj6); Console.ReadKey(); } } }
运行后测试结果显示如下：
