动态调用webservice(部分转载)
动态调用webservice,做个笔记：
1 public class WSHelper 2 { 3 /// < summary> 4 /// 动态调用web服务 5 /// < /summary> 6 /// < param name="url">WSDL服务地址< /param> 7 /// < param name="methodname">方法名< /param> 8 /// < param name="args">参数< /param> 9 /// < returns>< /returns> 10 public static object InvokeWebService(string url, string methodname, object[] args) 11 { 12 return WSHelper.InvokeWebService(url, null, methodname, args); 13 } 14 /// < summary> 15 /// 动态调用web服务 16 /// < /summary> 17 /// < param name="url">WSDL服务地址< /param> 18 /// < param name="classname">类名< /param> 19 /// < param name="methodname">方法名< /param> 20 /// < param name="args">参数< /param> 21 /// < returns>< /returns> 22 public static object InvokeWebService(string url, string classname, string methodname, object[] args) 23 { 24 string @namespace = "EnterpriseServerBase.WebService.DynamicWebCalling"; 25 if ((classname == null) || (classname == "")) 26 { 27 classname = WSHelper.GetWsClassName(url); 28 } 29 try 30 { //获取WSDL 31 WebClient wc = new WebClient(); 32 Stream stream = wc.OpenRead(url + "?WSDL"); 33 ServiceDescription sd = ServiceDescription.Read(stream); 34 ServiceDescriptionImporter sdi = new ServiceDescriptionImporter(); 35 sdi.AddServiceDescription(sd, "", ""); 36 CodeNamespace cn = new CodeNamespace(@namespace); 37 //生成客户端代理类代码 38 CodeCompileUnit ccu = new CodeCompileUnit(); 39 ccu.Namespaces.Add(cn); 40 sdi.Import(cn, ccu); 41 CSharpCodeProvider icc = new CSharpCodeProvider(); 42 //设定编译参数 43 CompilerParameters cplist = new CompilerParameters(); 44 cplist.GenerateExecutable = false; 45 cplist.GenerateInMemory = true; 46 cplist.ReferencedAssemblies.Add("System.dll"); 47 cplist.ReferencedAssemblies.Add("System.XML.dll"); 48 cplist.ReferencedAssemblies.Add("System.Web.Services.dll"); 49 cplist.ReferencedAssemblies.Add("System.Data.dll"); 50 //编译代理类 51 CompilerResults cr = icc.CompileAssemblyFromDom(cplist, ccu); 52 if (true == cr.Errors.HasErrors) 53 { 54 System.Text.StringBuilder sb = new System.Text.StringBuilder(); 55 foreach (System.CodeDom.Compiler.CompilerError ce in cr.Errors) 56 { 57 sb.Append(ce.ToString()); 58 sb.Append(System.Environment.NewLine); 59 } 60 throw new Exception(sb.ToString()); 61 } 62 //生成代理实例，并调用方法 63 System.Reflection.Assembly assembly = cr.CompiledAssembly; 64 Type t = assembly.GetType(@namespace + "." + classname, true, true); 65 object obj = Activator.CreateInstance(t); 66 System.Reflection.MethodInfo mi = t.GetMethod(methodname); 67 return mi.Invoke(obj, args); 68 // PropertyInfo propertyInfo = type.GetProperty(propertyname); 69 //return propertyInfo.GetValue(obj, null); 70 } 71 catch (Exception ex) 72 { 73 throw new Exception(ex.InnerException.Message, new Exception(ex.InnerException.StackTrace)); 74 } 75 } 76 private static string GetWsClassName(string wsUrl) 77 { 78 string[] parts = wsUrl.Split('/'); 79 string[] pps = parts[parts.Length - 1].Split('.'); 80 return pps[0]; 81 } 82 }
需要在web.config中添加webservice的地址。
<add key="ConnetionHisExist" value="http://10.10.99.8:8808/HisIsExist.asmx"/> <!--<add key="ConnetionUrlMsg" value="http://10.10.99.8:8082/MessageApi.asmx"/>--> <add key="ConnetionUrlMsg" value="http://112.74.203.57:8000/MessageApi.asmx"/>
动态调用方式:
1、取得webconfig中的webservice的值
string MsgWebServiceurl = ConfigurationManager.AppSettings["ConnetionUrlMsg"].ToString();//取得webconfig中webservice值
2、组建字符串数组，访问
1 string strxml = "<?xml version=\"1.0\" encoding=\"utf-8\" ?>" + 2 "<data>" + 3 "<OrderNo>" + dt.Rows[0]["order_no"].ToString() + "</OrderNo>" + 4 "<MerBillNo>" + dt.Rows[0]["merchant_billno"].ToString() + "</MerBillNo>" + 5 "<RefundMethod>" + "02" + "</RefundMethod>" + 6 "<Amount>" + dt.Rows[0]["real_cost"].ToString() + "</Amount>" + 7 "<OperUser>" + dt.Rows[0]["oper_user"].ToString() + "</OperUser>" + 8 "<TermNo>" + dt.Rows[0]["termno"].ToString() + "</TermNo>" + 9 "<HisRefundNo>" + dt.Rows[0]["merchant_billno"].ToString() + "</HisRefundNo>" + 10 "<HisNo>" + dt.Rows[0]["merchant_billno"].ToString() + "</HisNo>" + 11 "<ChannelTransNo>" + dt.Rows[0]["tran_no"].ToString() + "</ChannelTransNo>" + 12 "<PayAppSource>" + dt.Rows[0]["payappcode"].ToString() + "</PayAppSource>" + 13 "<PaySourceCode>" + dt.Rows[0]["paysourcecode"].ToString() + "</PaySourceCode>" + 14 "<Flushes>" + "1" + "</Flushes>" +//0-退款 1-冲正 15 "<SignType>" + "01" + "</SignType>" + 16 "<SignData>" + SignData + "</SignData>" + 17 "</data>"; 18 19 20 21 string[] argsMsg = new string[3];//组建字符串数组 22 argsMsg[0] = "F000105";//访问类型 23 argsMsg[1] = strxml;//入参 24 argsMsg[2] = "xml";//返回类型 xml ,json 25 object Msgresult = WSHelper.InvokeWebService(MsgWebServiceurl, "MuPayInterface", argsMsg);
3、接下来对返回的object转化为字符串，然后解析这个字符串xml。
4、调用其他入参不是xml类型的
1 string isExistWebServiceurl = ConfigurationManager.AppSettings["ConnetionHisExist"].ToString();//取得webconfig中webservice值 2 3 string[] args = new string[1]; 4 args[0] = tran_no; 5
6 object result = WSHelper.InvokeWebService(isExistWebServiceurl, "HisExistsOrNot", args);
返回的result是一个int类型，进行转换后，即可用了。
